What's in a name: The role of verbalization in reinforcement learning

(e.g., characters or fractals) and concrete stimuli (e.g., pictures of everyday objects) are used interchangeably in the reinforcement-learning literature. Yet, it is unclear whether the same learning processes underlie learning from these different stimulus types. In two preregistered experiments (N = 50 each), we assessed whether abstract and concrete stimuli yield different reinforcement-learning performance and whether this difference can be explained by verbalization. We argued that concrete stimuli are easier to verbalize than abstract ones, and that people therefore can appeal to the phonological loop, a subcomponent of the working-memory system responsible for storing and rehearsing verbal information, while learning. To test whether this verbalization aids reinforcement-learning performance, we administered a reinforcement-learning task in which participants learned either abstract or concrete stimuli while verbalization was hindered or not. In the first experiment, results showed a more pronounced detrimental effect of hindered verbalization for concrete than abstract stimuli on response times, but not on accuracy. In the second experiment, in which we reduced the response window, results showed the differential effect of hindered verbalization between stimulus types on accuracy, not on response times. These results imply that verbalization aids learning for concrete, but not abstract, stimuli and therefore that different processes underlie learning from these types of stimuli. This emphasizes the importance of carefully considering stimulus types. We discuss these findings in light of generalizability and validity of reinforcement-learning research.

The role of expectancies and selective interrogation of information in trait anxiety-linked affect when approaching potentially stressful future events

The present study examined cognitive mechanisms underpinning the increased tendency of individuals with high trait anxiety to experience inflation of negative affect when approaching potential stressors. Specifically, the roles of (1) disproportionately negative relative to positive expectancies (i.e., negative expectancy bias) and (2) disproportionately interrogating negative relative to positive information (i.e., negative interrogation bias), each concerning the potential stressor, were examined. High and low trait anxiety participants (N = 286) completed the experimental session, in which they were informed they may view a potentially stressful film. As participants approached the putative film viewing, participants' negative and positive affect, as well as their negative and positive expectancies were assessed. Additionally, negative interrogation bias was assessed by providing participants the opportunity to selectively interrogate information from a larger pool of negative and positive information concerning the putative film viewing. Our findings provide evidence indirect associations between trait anxiety and inflation of negative affect is serially mediated via negative interrogation bias and, in turn, negative expectancy bias. Findings are discussed with regards to limitations and potential implications for public health campaigns, and cognitive interventions for anxiety, highlighting the utility of further examining negative interrogation bias as an avenue for improving the efficacy of each.

Adolescents' attitudes, habits, identity and social support in relation to physical activity after the COVID-19 pandemic

This study focuses on adolescents' cognitive processes, behaviors and social support (SS) as they relate to physical activity (PA) before and after the pandemic. The aims of the study were: (1) to investigate the changes in adolescents' engagement in moderate and vigorous physical activity (MVPA), and examine the changes in PA-related attitudes and behaviors before and after the COVID-19 pandemic; (2) to analyze the correlations between the significant changes that were found, PA engagement, and SS. The survey targeted third-year middle school students of Italian nationality, attending male and female mixed classes, residents in urban, periphery and sub-urban areas, living in families with different incomes, and different habits of engaging in PA. A longitudinal study was developed using a standardized questionnaire. The questionnaire was administered in April-May 2023 to a sample of 952 students aged 11/14 residing in the Marche region in Central Italy. Increasing values were found in the post-COVID-19 phase for all the cognitive processes and attitudes, in particular, those regarding habits (0.66 vs 0.50, + 32%) and identity (0.70 vs 0.55, + 27%) related to PA. Significant correlations were found between these values and VPA engagement and between the values of the same indicators and SS (p < 0.01). The strongest relationship was found with the dimension of identity (r = 0.51; r = 054).

Connecting the dots: Exploring brain connectivity during responsibility recognition in construction contract negotiations

Despite recent advancements in monitoring brain activity, causal relationships within the brain during responsibility identification in construction contracts remain unexplored. We aimed to understand the neural mechanisms involved in the cognitive components and their interactions related to contract text reading by delving into the brain mechanisms of contract responsibility identification. This study investigated students' brain connectivity using electroencephalography (EEG) data during a text-based contract responsibility-identification task. It employed an adaptive directed transfer function based on Granger causality to simulate directed and time-varying information flow in observed brain activity. We evaluated the EEG records of 18 participants under two reading conditions (involving or not involving contractor responsibility). During responsibility identification, the most substantial information exchange occurs in the somatosensory area of the brain. The results revealed a "top-down" cortical mechanism for responsibility identification, with the left parietal-occipital area (PO3) as the central hub promoting connectivity structures. These findings indicate that the perceptual processing of contract responsibility texts is associated with higher visual learning and memory quality. Contracts without contractor-responsibility clauses resulted in more substantial information flow output in the frontal cortex and consumed more cognitive resources. Our findings advance the understanding of cognitive processes involved in contract responsibility identification, providing a framework for investigating causal relationships within the brain and novel insights into cortical mechanisms. By identifying the neural basis of responsibility identification, stakeholders can develop effective training programs for negotiators and enhance their ability to interpret and implement construction contracts.

Pseudodiagnosticity and preference hierarchy in a search-only inference paradigm

Bayes' Theorem provides a rationality-standard for information search when there are two mutually exclusive hypotheses and one or more statistical cues pertaining to the likelihoods of the hypotheses. Prior research shows that when people already have a cue pertaining to a hypothesis and are asked to seek additional information to help decide which hypothesis is correct, they tend to exhibit a specific form of pseudodiagnosticity: Rather than seek information that would assess the same cue relative to an alternative hypothesis, they tend to seek information about how a second cue would pertain to the first hypothesis. For example, if people are told that 70% of genuine paintings are landscapes, they then seek to know the percentage of genuine paintings that are watercolor rather than the percentage of fake paintings that are landscapes. However, this response pattern has sometimes been violated in a way that may depend on the cues' numerical values (e.g., 70% vs. 30%), thus raising a question as to the nature of the bias: Does the selection bias characterize the search process per se, or does it reflect the manner in which people utilize already-obtained percentage information? To address these issues, we employed a novel, search-only judgment paradigm in which people were asked to search for cues and to select them without ever obtaining the cues' percentage values. The results confirmed a tendency toward same-hypothesis pseudodiagnosticity both in primary (i.e., most-preferred) and secondary preference, and supported a model in which pseudodiagnosticity can proceed with or without numerical cue data.

Mental health after lumbar spine surgery: cognitive appraisal processes and outcome in a longitudinal cohort study

BACKGROUND CONTEXT

A not uncommon finding following spine surgery is that many patients do not achieve mental health improvement up to population norms for their age cohort, despite improvement in pain and functioning.

PURPOSE

This study examined how patients who were categorized as depressed versus not depressed think about health-related quality of life as assessed by cognitive-appraisal processes. It examined cross-sectional and longitudinal differences over 12 months post-surgery.

DESIGN

Prospective longitudinal cohort study with data collected at pre-surgery and at ∼3- and ∼12-months post-surgery from August 2013 to August 2023.

PATIENT SAMPLE

We included 173 adults undergoing lumbar spine surgery for degenerative spinal conditions at an academic medical center. The study sample was 47% female, with a mean age of 61 (SD=15.0), and a median level of education of college graduate.

OUTCOME MEASURES

Depression was defined as a Mental Component Score (MCS)≤38 on the Rand-36, building on studies that equated MCS scores with significant depression as assessed by clinically validated depression scales. The Quality-of-Life Appraisal Profile assessed the cognitive-appraisal domains of Experience Sampling and Standards of Comparison.

METHODS

The analysis focused on two comparisons: cross-sectionally comparing those who were not depressed (n=82) to those who were depressed (n=77) at baseline; and comparing longitudinal trajectories among those depressed before surgery and improved (n=54) versus did not improve (n=23). T-tests characterized group differences in appraisal endorsement; analysis of variance evaluated appraisal items in terms of explained variance; and Pearson correlation coefficients assessed direction of association in predicting mental health.

RESULTS

There were pre-surgical and longitudinal differences in both cognitive appraisal domains. Before surgery, depressed patients were less likely than non-depressed patients to endorse emphasizing the positive; more likely to focus on worst moments, recent flare-ups, their spinal condition, and the future; and more likely to compare themselves to high aspirations (eg, perfect health). Over time, among those who were depressed before surgery, those who improved focused decreasingly on worst moments and on the time before their spinal condition, and increasingly on emphasizing the positive and balancing the positives/negatives. Appraisal explained more variance in mental health among those who did not improve as compared to those who did, at all timepoints. All appraisal items were more highly correlated with mental health among those who remained depressed as compared to those who improved, particularly over time.

CONCLUSIONS

Endorsement of cognitive appraisal processes was different for depressed versus non-depressed spine-surgery patients before surgery and distinguished those who were depressed before surgery and improved versus those who did not improve. These findings suggest that targeted interventions could be beneficial for addressing mental health concerns during the spine surgery recovery trajectory. These interventions might use appraisal measures to identify patients likely to remain depressed after surgery, and then focus on helping these patients shift their focus and standards of comparison.

Food rejection and the relation with category-based induction and memory in young children

BACKGROUND

Childhood rejection of fruits and vegetables (F/V) has been associated with an immature food categorization system, characterized by difficulties in accurately categorizing and making inductions about foods. This may result in variations in the kind of category-based induction children use, such as relying on the color of a fruit/vegetable. Research indicates that children who reject food frequently tend to prioritize perceptual features like color and shape over abstract features, such as the type of food (e.g., tomato) when making food-related inductions. The way children categorize food can also impact what they remember about foods. Food rejection may therefore be related to better memory for perceptual features and diminished memory for abstract features. To explore this further, a pre-registered study was conducted to examine how category-based induction and memory relate to each other, and to children's food rejection.

METHODS

107 children aged 4-6 years old performed a category-based induction and memory task related to F/V, based on color and shape (perceptual features), and type of food (abstract feature). A vegetable photo task measured vegetable acceptance, and parents completed the Child Food Rejection Scale (CFRS).

RESULTS

Children generally used color-based induction and displayed better memory for F/V color. Performance on the two tasks was related: higher type-based induction for F/V was linked to better memory for the type of F/V. However, there were no associations found with food rejection.

CONCLUSION

Which category young children use for inductive reasoning about food, is related to what they remember best about food. Nevertheless, our study did not establish a relationship between an immature food categorization system and food rejection. Other factors, such as food familiarity, might play a stronger role in children's food acceptance.

The impact of brivaracetam on cognitive processes and anxiety in various experimental models

BACKGROUND

Memory deficits and anxiety symptoms are undesirable effects that occur in epilepsy patients. They may be associated with the pathophysiology of the disease but also with anticonvulsant therapy. Brivaracetam (BRV) is one of the newest antiseizure drugs. It acts as a ligand for synaptic vesicle glycoprotein 2A (SV2A), which may play a significant role in cognitive processes. Although BRV has a favorable safety profile, its central side effects remain unclear. Hence, this study aimed to evaluate the effect of BRV on various types of memory and anxiety in rats.

METHODS

BRV was given to adult male Wistar rats (n = 80) via gastric tube as a single dose (6 mg/kg or 20 mg/kg) or chronically (6 mg/kg). The effect of the drug on spatial memory was evaluated in the Morris water maze (MWM), fear-learning by passive avoidance (PA), and recognition memory with novel object recognition (NOR). The elevated plus maze (EPM) was used to assess anxiety-like behaviors.

RESULTS

The impact of BRV on memory is dose-dependent and mainly high doses may alter retrieval memory and fear-learning. Sub-chronic administration also impaired retrieval and spatial memory in animals. Moreover, chronic BRV may increase anxiety levels in rats but did not affect recognition memory.

CONCLUSIONS

BRV may cause transient memory deficits as well as anxiety disturbances. However, the results are varied and depend on the type of memory, used dose, and duration of administration.

Worry, rumination and negative metacognitive beliefs as moderators of outcomes of Transdiagnostic group cognitive-behavioural therapy in emotional disorders

BACKGROUND

Despite the relevance of cognitive processes such as rumination, worry, negative metacognitive beliefs in emotional disorders, the existing literature about how these cognitive processes moderate the effect of treatment in treatment outcomes is limited. The aim of the present study was to explore the potential moderator effect of baseline cognitive processes-worry, rumination and negative metacognitive beliefs-on the relationship between treatment allocation (transdiagnostic cognitive-behavioural therapy -TD-CBT plus treatment as usual-TAU vs. TAU alone) and treatment outcomes (anxiety and depressive symptoms, quality of life [QoL], and functioning) in primary care patients with emotional disorders.

METHODS

A total of 631 participants completed scales to evaluate worry, rumination, negative metacognitive beliefs, QoL, functioning, and anxiety and depressive symptoms.

RESULTS

Worry and rumination acted as moderators on the effect of treatment for anxiety (b = -1.25, p = .003; b = -0.98, p = .048 respectively) and depressive symptoms (b = -1.21, p = .017; b = -1.34, p = .024 respectively). Individuals with higher baseline levels of worry and rumination obtained a greater reduction in emotional symptoms from the addition TD-CBT to TAU. Negative metacognitive beliefs were not a significant moderator of any treatment outcome.

LIMITATIONS

The study assesses cognitive processes over a relatively short period of time and uses self-reported instruments. In addition, it only includes individuals with mild or moderate anxiety or depressive disorders, which limits generalization to other populations.

CONCLUSIONS

These results underscore the generalization of the TD-CBT to individuals with emotional disorders in primary care with different cognitive profiles, especially those with high levels of worry and rumination.

Cognitive Processes and Translation Quality: Evidence from Keystroke-Logging Software

This study investigates the relationship between cognitive processes and translation quality in the context of English-Arabic translations of journalistic articles. Specifically, it explores the translation processes at the orientation, production, and revision stages and the relationship between such processing and translation quality, using keylogging software (i.e., Translog II) to record the experiment. Twenty-two translation trainees participated in the study, translating a news article from English into Arabic. Presas's (2012) rubric for assessment was used to evaluate the translation quality, and several correlation analyses were applied to the data. Findings revealed negative correlations between translation quality and online revision, translation duration, and text production. The trainees' translations demonstrated limitations in communicating the main ideas of the target text (TT) to the target language (TL). The findings also showed the trainees' focus on online revision and editing and the concentration of translation time and cognitive effort in the drafting phase. The researchers recommend including the three phases of translation (reading, drafting, and revision) into translation training courses and equipping translator trainees with the required skills for each translation stage.

Impaired prediction of ongoing events in posttraumatic stress disorder

The ability to make accurate predictions about what is going to happen in the near future is critical for comprehension of everyday activity. However, predictive processing may be disrupted in Posttraumatic Stress Disorder (PTSD). Hypervigilance may lead people with PTSD to make inaccurate predictions about the likelihood of future danger. This disruption in predictive processing may occur not only in response to threatening stimuli, but also during processing of neutral stimuli. Therefore, the current study investigated whether PTSD was associated with difficulty making predictions about near-future neutral activity. Sixty-three participants with PTSD and 63 trauma controls completed two tasks, one testing explicit prediction and the other testing implicit prediction. Higher PTSD severity was associated with greater difficulty with predictive processing on both of these tasks. These results suggest that effective treatments to improve functional outcomes for people with PTSD may work, in part, by improving predictive processing.

Inertia in cognitive processes: the case of the COVID-19 vaccine

Developments in factor analysis (Spearman in Am J Psychol 15:201-292, 1904); Thurstone in Multiple factor analysis, University of Chicago Press, Chicago, 1947), multidimensional scaling (Torgerson in Theory and methods of scaling, Wiley Hoboken, New Jersey, 1958; Young and Householder in Psychometrika, 3:19-22, 1938), the Galileo model (Woelfel and Fink in The measurement of communication processes: galileo theory and method, Academic Press Cambridge, Massachusetts, 1980), and, more recently, in computer science, artificial intelligence, computational linguistics, network analysis and other disciplines (Woelfel in Qual Quant 54:263-278, 2020) have shown that human cognitive and cultural beliefs and attitudes can be modeled as movement through a high-dimensional non-Euclidean space. This article demonstrates the theoretical and methodological contribution that multidimensional scaling makes to understand attitude change associated with the COVID-19 vaccine.

Working memory load affects intelligence test performance by reducing the strength of relational item bindings and impairing the filtering of irrelevant information

There is a broad consensus that individual differences in working memory capacity (WMC) are strongly related to individual differences in intelligence. However, correlational studies do not allow conclusions about the causal nature of the relationship between WMC and fluid intelligence. While research on the cognitive basis of intelligence typically assumes that simpler lower-level cognitive processes contribute to individual differences in higher-order reasoning processes, a reversed causality or a third variable giving rise to two intrinsically uncorrelated variables may exist. In two studies (n₁ = 65, n₂ = 113), we investigated the causal nature of the relationship between WMC and intelligence by assessing the experimental effect of working memory load on intelligence test performance. Moreover, we tested if the effect of working memory load on intelligence test performance increased under time constraints, as previous studies have shown that the association between the two constructs increases if intelligence tests are administered with a strict time limit. We show that working memory load impaired intelligence test performance, but that this experimental effect was not affected by time constraints, which suggests that the experimental manipulations of working memory capacity and processing time did not affect the same underlying cognitive process. Using a computational modeling approach, we demonstrated that external memory load affected both the building and maintenance of relational item bindings and the filtering of irrelevant information in working memory. Our results confirm that WMC causally contributes to higher-order reasoning processes. Moreover, they support the hypothesis that working memory capacity in general and the abilities to maintain arbitrary bindings and to disengage from irrelevant information in particular are intrinsically related to intelligence.

Breaking boundaries: The Bayesian Brain Hypothesis for perception and prediction

This special issue aims to provide a comprehensive overview of the current state of the Bayesian Brain Hypothesis and its standing across neuroscience, cognitive science and the philosophy of cognitive science. By gathering cutting-edge research from leading experts, this issue seeks to showcase the latest advancements in our understanding of the Bayesian brain, as well as its potential implications for future research in perception, cognition, and motor control. A special focus to achieve this aim is adopted in this special issue, as it seeks to explore the relation between two seemingly incompatible frameworks for the understanding of cognitive structure and function: the Bayesian Brain Hypothesis and the Modularity Theory of the Mind. In assessing the compatibility between these theories, the contributors to this special issue open up new pathways of thinking and advance our understanding of cognitive processes.

Depressive symptoms and persistent negative self-referent thinking among adolescents: A learning account

Learning theories of depression propose that negative thinking is acquired through subsequent rewarding experiences and is often resistant to change even when it becomes associated with punishment. We examined whether this persistency of negative thinking is related to current and future levels of depressive symptoms among adolescents. Persistency of negative self-referent thinking was assessed by means of a decision-making task, namely the emotional reversal learning task. This task offers participants the choice between thinking about negative and positive self-related aspects. Their choice for negative self-referent thinking is initially rewarded but is later punished. Therefore, participants were expected to efficiently switch between negative and positive self-referent thinking, and to internally update their reward expectancy for these thinking options. Results showed that persistency of negative self-referent thinking was related to concurrent levels of depressive symptoms, replicating earlier findings in adults. However, persistency of negative thinking was unrelated to future levels of depressive symptoms. These findings suggest that adolescents with depressive symptoms tend to hold on to the belief that negative self-referent thinking has beneficial consequences, even when it is no longer being rewarded. This tendency should be seen as a concurrent feature of depression, as the predictive value is still in question.

Development and psychometric evaluation of a scrambled sentences test specifically for worry in individuals with generalised anxiety disorder

The tendency to draw negative conclusions from ambiguous information (interpretation bias) is prevalent across emotional disorders and plays a key role in the development and maintenance of pathological worry and anxious mood. Assessing interpretation bias using valid and reliable measures is central to empirical research. A commonly used measure of interpretation bias is the scrambled sentences test (SST), originally relating to depression. Given the association between interpretation bias and worry, we aimed to develop and psychometrically evaluate a new version of the SST with items pertaining to common worry domains for use in worry and anxiety research. In Studies 1-3 (analogue samples, combined N = 288), the new worry SST showed excellent construct validity (moderate-to-strong associations with worry and anxiety-related measures), and reliability (split-half and test-retest reliability). We confirmed construct validity in Study 4 (N = 215 individuals with generalised anxiety disorder). Furthermore, we demonstrated version specificity in analogue and clinical samples: the worry SST was associated with trait worry but not trait rumination, while the original depression SST largely showed the opposite pattern. Overall, the new worry SST is a psychometrically robust measure that may be especially useful for research into cognitive processes underpinning worry and anxiety.

Attentional Bias Toward Threat in Sexually Victimized Hispanic Women: A Dot Probe Study

The current study examined attentional bias toward threat in Hispanic college women exposed to lifetime sexual victimization in childhood, adulthood, and both childhood and adulthood. Response latencies and attention bias scores were compared between victimized and non-victimized individuals. Participants were 20 women exposed to adulthood sexual victimization (AS group), 15 exposed to childhood sexual victimization (CS group), 8 exposed to both childhood and adulthood sexual assault (revictimization: RV group), and 20 not endorsing sexual victimization (NS group). They were asked to complete the dot-probe task. The CS group and RV group were combined to create the CS-RV group. Among the AS and CS-RV groups, response latencies were faster when attention was engaged to threat than when attention was engaged to non-threat. The NS group did not demonstrate such differences. When response latencies were compared among the three groups, the CS-RV group had slower response latencies than the NS group. The CS-RV and AS groups revealed similarly significantly elevated bias scores toward threat words than the NS group. Hispanic college women exposed to lifetime sexual victimization display elevated levels of attention bias compared to non-victimized women. Further, the current findings align with an integrative cognitive model for explaining maladaptive informational processing in trauma victims.

Investigating the response scale of the EORTC QLQ-C30 in German cancer patients and a population survey

BACKGROUND

The European Organization for research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) scales are scored on a 4-point response scale, ranging from not at all to very much. Previous studies have shown that the German translation of the response option quite a bit as mäßig violates interval scale assumptions, and that ziemlich is a more appropriate translation. The present studies investigated differences between the two questionnaire versions.

METHODS

The first study employed a balanced cross-over design and included 450 patients with different types of cancer from three German-speaking countries. The second study was a representative survey in Germany including 2033 respondents. The main analyses included compared the ziemlich and mäßig version of the questionnaire using analyses of covariance adjusted for sex, age, and health burden.

RESULTS

In accordance with our hypothesis, the adjusted summary score was lower in the mäßig than in the ziemlich version; Study 1: - 4.5 (95% CI - 7.8 to - 1.3), p = 0.006, Study 2: - 3.1 (95% CI - 4.6 to - 1.5), p < 0.001. In both studies, this effect was pronounced in respondents with a higher health burden; Study 1: - 6.8 (95% CI - 12.2 to - 1.4), p = 0.013; Study 2: - 4.5 (95% CI - 7.3 to - 1.7), p = 0.002.

CONCLUSIONS

We found subtle but consistent differences between the two questionnaire versions. We recommend to use the optimized response option for the EORTC QLQ-C30 as well as for all other German modules.

TRIAL REGISTRATION

The study was retrospectively registered on the German Registry for Clinical Studies (reference number DRKS00012759, 04th August 2017, https://www.drks.de/DRKS00012759 ).

Measures of explicit and implicit in motor learning: what we know and what we don't

Adaptation tasks are a key tool in characterizing the contribution of explicit and implicit processes to sensorimotor learning. However, different assumptions and ideas underlie methods used to measure these processes, leading to inconsistencies between studies. For instance, it is still unclear explicit and implicit combine additively. Cognitive studies of explicit and implicit processes show how non-additivity and bias in measurement can distort results. We argue that to understand explicit and implicit processes in visuomotor adaptation, we need a stronger characterization of the phenomenology and a richer set of models to test it on.

Cognitive processes related to problematic pornography use (PPU): A systematic review of experimental studies

INTRODUCTION

Some people experience symptoms and negative outcomes derived from their persistent, excessive, and problematic engagement in pornography viewing (i.e., Problematic Pornography Use, PPU). Recent theoretical models have turned to different cognitive processes (e.g., inhibitory control, decision making, attentional bias, etc.) to explain the development and maintenance of PPU, but empirical evidence derived from experimental studies is still limited. In this context, the present systematic review aimed to review and compile the evidence around cognitive processes related to PPU.

METHODS

A systematic review was performed in accordance with PRISMA guidelines to compile evidence regarding cognitive processes related to PPU. We retained and analyzed 21 experimental studies addressing this topic.

RESULTS

Studies were focused on four cognitive processes: attentional bias, inhibitory control, working memory, and decision making. In brief, PPU is related to (a) attentional biases toward sexual stimuli, (b) deficient inhibitory control (in particular, to problems with motor response inhibition and to shift attention away from irrelevant stimuli), (c) worse performance in tasks assessing working memory, and (d) decision making impairments (in particular, to preferences for short-term small gains rather than long-term large gains, more impulsive choice patterns than non-erotica users, approach tendencies toward sexual stimuli, and inaccuracies when judging the probability and magnitude of potential outcomes under ambiguity).

CONCLUSION

This systematic review offers a comprehensive overview of the current state of knowledge regarding the cognitive features related to PPU, and points out new areas that warrants further research.

Transdiagnostic Cognitive Processes in Chronic Pain and Comorbid PTSD and Depression in Veterans

BACKGROUND

Chronic pain in Veterans is a major problem compounded by comorbid posttraumatic stress disorder (PTSD) and depression. Adopting a transdiagnostic framework to understanding "shared territory" among these diagnoses has the potential to inform our understanding of the underlying cognitive processes and mechanisms that transverse diagnostic boundaries.

PURPOSE

To examine the associations between pain-related cognitive processes (diversion, distancing, absorption, and openness), pain intensity, PTSD and depressive symptoms, and the extent to which Veterans with chronic pain with and without comorbid PTSD and depression engage in different/similar pain-related cognitive processes.

METHODS

Secondary analysis of pretreatment data with a subsample (n = 147) of Veterans with chronic pain from a larger clinical trial. Pretreatment PCL-5 and PROMIS Depression scales were used to categorize participants into three groups: (a) Pain-only; (b) Pain-PTSD; and (c) Pain-PTSD-DEP.

RESULTS

Compared to the Pain-only group, the Pain-PTSD and Pain-PTSD-DEP groups reported significantly greater pain intensity, PTSD and depressive symptoms, and ruminative pain absorption. The Pain-PTSD-DEP group had significantly lower pain diversion and pain openness scores. When diversion and openness were used within the Pain-PTSD-DEP group, however, they were both associated with lower pain intensity and openness was additionally associated with lower PTSD scores. However, in the Pain-PTSD group, pain openness was associated with higher depression scores.

CONCLUSIONS

Across increasing complexity of comorbidity profiles (i.e., one vs. two comorbid conditions), ruminative absorption with pain emerged as a cognitive process that transverses diagnoses and contributes to worse outcomes. Nonjudgmental acceptance may not be universally beneficial, potentially depending upon the nature of comorbidity profiles.

A comprehensive approach to study the resting-state brain network related to creative potential

Studies related to creativity generally investigate cognition and brain functioning linked to creative achievement. However, this approach does not allow characterization of creative potential. To better define creative potential, we studied cognitive function related to creative processes and the associated brain resting functional connectivity. Therefore, in this pilot study, we constructed a cognitive functioning model via structural equation modeling assuming an influence of working memory (WM) and analytical thinking on creativity assessed by the Torrance Tests of Creative Thinking. On the basis of this model, we differentiated two groups with different functioning levels on the basis of their creative score. We identified one group as the high-creative potential group, with a positive correlation between WM and creativity and a negative correlation between analytical thinking and creativity. The other group was the low-creative potential group, with no correlation between WM and creativity and a negative correlation between analytical thinking and creativity. Then, we examined brain functional connectivity at rest and found that the high-creative potential group had increased connectivity in the attentional network (AN) and default-mode network (DMN) and decreased connectivity in the salience network (SN). Our findings highlight the involvement of the AN. We, therefore, linked this network to creative potential, which is consistent with cognitive theories suggesting that creativity is underpinned by attentional processes.

Enhancing medical radiation science education through a design science research methodology

Recently, there has been a call for research-informed and research-developed practice in health sciences education. This prompts the consideration of alternative suitable research approaches that could be used to enhance health sciences education practice, including medical radiation sciences education (MRSE) practice. In this discussion paper, the authors uphold design science research (DSR) methodology as a suitable research approach to enhance MRSE practice and research. An overview of the DSR methodology and an example of a project that used DSR methodology are presented to demonstrate the application of this methodology in MRSE practice and research. The paper concludes that the use of DSR methodology could be instrumental in addressing practice related challenges while developing a theoretical contribution to the discipline.

Cognitive processes and a centre-of-pressure error-based moving light-touch biofeedback

Lightly touching an earth-fixed external surface with the forefinger provides somatosensory information that reduces the center of pressure (CoP) oscillations. If this surface were to move slowly, the central nervous system (CNS) would misinterpret its movement as body self-motion, and involuntary compensatory sway responses would appear, resulting in a significant coupling between finger and CoP motions. We designed a forefinger moving light-touch biofeedback based on this finding, which controls the surface velocity to drive the CoP towards a target position. Here, we investigate this biofeedback resistance to cognitive processes. In addition to a baseline, the experimental protocol includes four main conditions. In the first, participants were utterly naive about the feedback. Then, they received additional reliable sensory information. The third condition ensured their full awareness of the external nature of the surface motion. Finally, the experimenter notified them that the external motion drives their balance and asked them to reject its influence. Our investigation shows that despite the robustness of the proposed biofeedback, light-touch remains penetrable by cognitive processes. For participants to dramatically reduce the existing coupling between the finger and CoP motions, they should be aware of the external motion, how it impacts sway, and actively reject its influence. The main implication of our findings is that light-touch exhibits the same cognitive flexibility as vision when artificially stimulated. This could be interpreted as a defense mechanism to re-weight these two sensory inputs in a moving environment.

Cognitive and emotional regulation in adolescents and young women with eating disorders

BACKGROUND

Eating disorders (EDs) are associated with a reduced ability to regulate emotion and impulses during the life span. Working memory and executive functions (EFs) are cognitive regulatory systems supported by networks involving the pre-frontal cortex. Studies in EDs found impaired functioning in these domains, showing an association between EDs and the reduced ability to control emotions and impulses.

OBJECTIVE

To investigate EF in adolescents and young women with eating disorders (ED) using a quasi-experimental design, focusing on cognitive efficiency, emotional regulation (ER) and behavioural outcomes also taking into account pharmacological treatment and duration of illness.

METHODS

A sample of 151 females belonging to two groups took part in this study. Twenty-six girls and young women (M_age 22;8 years) with ED and 125 typically developed girls and young women (M_age 17;4 years) completed a battery of cognitive tasks (Go-no-go, Stop-signal task, Symmetry span, Reading Span) and the Youth Self-Report and the Difficulties in Emotional Regulation Scale Performance. A series of ANOVA with the Brown-Forsythe test was used to compare the groups.

RESULTS

Participants with ED and controls did not show significant differences in EF tasks, whereas differences between younger and older participants with ED emerged. Moreover, ER difficulties seem to be associated with mainly internalizing problems in EDs. Further analysis on the full ED sample did not reveal any significant differences associated with the disorder persistence. Considering pharmacological treatment effects over cognitive, emotional and behavioural measures emerged.

CONCLUSIONS

The present study documented no specific differences in EF between control and participants with EDs, whereas important differences emerged in ER and behavioural outcomes perception in the clinical sample, together with a partial influence of pharmacological treatment.

Resting-state posterior alpha power changes with prolonged exposure in a natural environment

Exposure to environments that contain natural features can benefit mood, cognition, and physiological responses. Previous research proposed exposure to nature restores voluntary attention - attention that is directed towards a task through top down control. Voluntary attention is limited in capacity and depletes with use. Nature provides unique stimuli that do not require voluntary attention; therefore, the neural resources needed for attention to operate efficiently are theorized to restore when spending time in nature. Electroencephalography reflects changes in attention through fluctuations in power within specific frequencies. The current study (N = 29) measured changes in averaged resting state posterior alpha power before, during, and after a multiday nature exposure. Linear mixed-effects models revealed posterior alpha power was significantly lower during the nature exposure compared to pre-trip and post-trip testing, suggesting posterior alpha power may be a potential biomarker for differences related to exposure to natural and urban environments.

Do Children and Adults with Autism Spectrum Condition Anticipate Others' Actions as Goal-Directed? A Predictive Coding Perspective

An action's end state can be anticipated by considering the agent's goal, or simply by projecting the movement trajectory. Theories suggest that individuals with autism spectrum condition (ASC) have difficulties anticipating other's goal-directed actions, caused by an impairment using prior information. We examined whether children, adolescents and adults with and without ASC visually anticipate another's action based on its goal or movement trajectory by presenting participants an agent repeatedly taking different paths to reach the same of two targets. The ASC group anticipated the goal and not just the movement pattern, but needed more time to perform goal-directed anticipations. Results are in line with predictive coding accounts, claiming that the use of prior information is impaired in ASC.

Challenges and opportunities for top-down modulation research in cognitive psychology

Studying social modulation of cognitive processes holds much promise for illuminating how, where, when and why social factors influence how we perceive and act in the world, as well as providing insight into the underlying cognitive mechanisms. This is no small objective; it reflects an ambitious programme of research. At present, based on the modal theoretical and methodological approach, we suggest that several challenges exist to achieving such lofty aims. These challenges span an overreliance on a simplistic dichotomy between "top-down" and "bottom-up" modulation, a lack of specificity about mechanisms that renders clear interpretations difficult, and theories that largely test against null hypotheses. We suggest that these challenges present several opportunities for new research and we encourage the field to abandon simplistic dichotomies and connect much more with existing research programmes such as semantics, memory and attention, which have all built diverse research platforms over many decades and that can help shape how social modulation is conceptualised and studied from a cognitive and brain perspective. We also outline ways that stronger theoretical positions can be taken, which avoid comparing to null hypotheses, and endorse methodological reform through fully embracing proposals from the open science movement and "credibility revolution". We feel that by taking these opportunities, the field will have a better chance of reaching its potential to build a cumulative science of social modulation that can inform understanding of basic cognitive and brain systems, as well as real-life social interactions and the varied abilities observed across the Autism Spectrum.

Change in implicit alcohol associations over time: Moderation by drinking history and gender

Implicit measures of alcohol-related associations or implicit alcohol associations are associated with drinking outcomes over time and can be understood as vulnerability markers for problem drinking. Longitudinal research remains rare, leaving open questions about how implicit alcohol associations themselves change over time and what factors moderate that change. We examined these questions with data from a larger study of first and second year U.S. college students. We investigated how these implicit alcohol associations change over time and potential moderators of those changes (gender, lifetime drinking history, family history of problem drinking, and class standing). A sample of 506 students (57% women) completed baseline demographic measures and implicit measures (variants of the Implicit Association Test [IAT]) assessing associations with drinking and the self [drinking identity], alcohol and excite [alcohol-excite], and alcohol and approach [alcohol-approach]). IATs were completed at 3-month intervals for a total of 8 assessments. Results indicated small, but significant, change in alcohol-excite and alcohol-approach IAT scores over time, and mixed findings for hypothesized moderators. Drinking history moderated change in drinking identity IAT scores, with increases over time among individuals with no history of drinking or no history of intoxication and decreases among individuals with a history of intoxication. Gender moderated change in alcohol-excite IAT scores with greater change among women (vs. men). No significant moderators of change in alcohol approach IAT scores were found. Results point to the importance of evaluating implicit associations' trajectories and identifying additional factors that predict those trajectories and concomitant vulnerability to problem drinking.

Effects of live and video simulation on clinical reasoning performance and reflection

Introduction

In recent years, researchers have recognized the need to examine the relative effectiveness of different simulation approaches and the experiences of physicians operating within such environments. The current study experimentally examined the reflective judgments, cognitive processing, and clinical reasoning performance of physicians across live and video simulation environments.

Methods

Thirty-eight physicians were randomly assigned to a live scenario or video case condition. Both conditions encompassed two components: (a) patient encounter and (b) video reflection activity. Following the condition-specific patient encounter (i.e., live scenario or video), the participants completed a Post Encounter Form (PEF), microanalytic questions, and a mental effort question. Participants were then instructed to re-watch the video (i.e., video condition) or a video recording of their live patient encounter (i.e., live scenario) while thinking aloud about how they came to the diagnosis and management plan.

Results

Although significant differences did not emerge across all measures, physicians in the live scenario condition exhibited superior performance in clinical reasoning (i.e., PEF) and a distinct profile of reflective judgments and cognitive processing. Generally, the live condition participants focused more attention on aspects of the clinical reasoning process and demonstrated higher level cognitive processing than the video group.

Conclusions

The current study sheds light on the differential effects of live scenario and video simulation approaches. Physicians who engaged in live scenario simulations outperformed and showed a distinct pattern of cognitive reactions and judgments compared to physicians who practiced their clinical reasoning via video simulation. Additionally, the current study points to the potential advantages of video self-reflection following live scenarios while also shedding some light on the debate regarding whether video-guided reflection, specifically, is advantageous. The utility of context-specific, micro-level assessments that incorporate multiple methods as physicians complete different parts of clinical tasks is also discussed.

Appraisals and coping mediate the relationship between resilience and distress among significant others of persons with spinal cord injury or acquired brain injury: a cross-sectional study

Background

Many significant others of persons with serious conditions like spinal cord injury (SCI) and acquired brain injury (ABI) report high levels of psychological distress. In line with the stress-coping model, the aim of the present study was to investigate the relationship between personal resource resilience and psychological distress, and whether appraisals of threat and loss, and passive coping mediate this relationship.

Methods

Significant others (n = 228) of persons with SCI or ABI completed questionnaires shortly after admission to first inpatient rehabilitation after onset of the condition. The questionnaire included measures to assess psychological distress (Hospital Anxiety and Depression Scale), resilience (Connor-Davidson Resilience Scale-10), appraisals (Appraisals of Life Events scale, threat and loss) and passive coping (Utrecht Coping List). The PROCESS tool was used to test the presence of mediation. Confounding and differences between SCI and ABI were investigated.

Results

High levels of psychological distress among significant others were found (34–41%). Fifty-five percent of the variance in psychological distress was explained by the relationship between resilience and psychological distress. This relationship was mediated by appraisals of threat and loss, and passive coping. The relationship between resilience and psychological distress was similar in the SCI and ABI groups.

Conclusions

The results of our study indicate that appraisals of threat and loss and passive coping are mediating factors in the relationship between resilience and psychological distress. It seems useful to investigate if interventions focussing on psychological factors like resilience, appraisal and coping are effective to prevent or reduce psychological distress among significant others of persons with SCI or ABI.

How to Explain Behavior?

Unlike behaviorism, cognitive psychology relies on mental concepts to explain behavior. Yet mental processes are not directly observable and multiple explanations are possible, which poses a challenge for finding a useful framework. In this article, I distinguish three new frameworks for explanations that emerged after the cognitive revolution. The first is called tools-to-theories: Psychologists' new tools for data analysis, such as computers and statistics, are turned into theories of mind. The second proposes as-if theories: Expected utility theory and Bayesian statistics are turned into theories of mind, describing an optimal solution of a problem but not its psychological process. The third studies the adaptive toolbox (formal models of heuristics) that describes mental processes in situations of uncertainty where an optimal solution is unknown. Depending on which framework researchers choose, they will model behavior in either situations of risk or of uncertainty, and construct models of cognitive processes or not. The frameworks also determine what questions are asked and what kind of data are generated. What all three frameworks have in common, however, is a clear preference for formal models rather than explanations by general dichotomies or mere verbal concepts. The frameworks have considerable potential to inform each other and to generate points of integration.

Patterns of interrelation between perception and understanding of images and texts with different degree of blur

The efficiency of information processing depends on a holistic and integrated process of understanding. Eye tracking helps us to study the peculiarities of the understanding of visually perceived stimuli. The purpose of this study was to identify and characterize the relationship between perception and understanding, on the example of images and texts with different degrees of blurring (visual complexity). The work involved 25 participants, ages 19 to 25 years. Methods include poll, recording eye movements (eye tracking), wavelet filtering of text and images, and content analysis. Stimuli were consistently presented on the screen included text stimuli (from 7 texts), episodes from Russian fairy tales, and images (from 8 comics total), each consisting of eight pictures, united by one complete plot. Visual stimuli were presented in order from the clearest to the most blurred image. The results of the study showed that the participants made more gaze fixations on plot-relevant details and characters. They reveal key details of images for a general understanding of the content. The willful regulation of cognitive processes allows distinguishing the main characters and keywords to recreate or anticipate the meaning of visually perceived information constructs while reading texts or pictures with a high degree of blur.

Knowledge revision through the lenses of the three-pronged approach

In the present study, we employed the three-pronged approach to determine the actual cognitive processes theorized in knowledge revision. First, the Knowledge Revision Components (KReC) framework was identified as the guiding theory. Second, think-aloud analysis highlighted at which points in refutation texts readers detected discrepancies between their incorrect, commonsense beliefs and the correct beliefs, and the exact processes with which they dealt with these discrepancies-successfully or unsuccessfully, as indicated by posttest scores. Third, corroborating reading-time data and posttest data demonstrated that the structure of the refutation texts facilitated the coactivation and integration of the explanation with the commonsense belief, resulting in knowledge revision. Finally, an analysis directly connected the processes identified during think-aloud to sentence reading times. These findings systematically identify the cognitive processes theorized during knowledge revision and, in doing so, provide evidence for the conditions for revision outlined in the KReC framework.

Social influences on cognitive processing in enacted social support: effects on receivers' cognitive appraisals, emotion, and affiliation

Background and objectives. Social support is linked with psychological health, but its mechanisms are unclear. We examined supporters' influence on recipients' cognitive processing as a mechanism of effects of support on outcomes associated with depression. Design/methods. 2 × 2 between-subjects experiment. 147 participants (1) experienced a negative event (false feedback); (2) received social support modeling one of two contrasting cognitive processing modes (abstract/evaluative or concrete/experiential); (3) generated explanations for the event, later coded for processing mode and internal/external causal attribution; and (4) reported on emotion, perceptions of self and future, and social affiliation. To examine relational effects, half of participants were led to perceive the supporter as similar to themselves via a shared birthday manipulation. Results. Support condition influenced participants' processing mode and causal attributions as predicted. Abstract/evaluative support led to more positive emotion and self-perceptions, and less pessimistic expectancies for the future than concrete/experiential support. Perceived similarity moderated effects on beliefs about an upcoming social interaction, magnifying positive affiliation outcomes of abstract/evaluative versus concrete/experiential support. Conclusions. Processing modes that are generally maladaptive at the intrapersonal level may be adaptive (and vice versa) when they are interpersonally influenced, and perceived similarity may facilitate interpersonal effects of processing mode on affiliation.

Design factors in mouse-tracking: What makes a difference?

Investigating cognitive processes by analyzing mouse movements has become a popular method in many psychological disciplines. When creating mouse-tracking experiments, researchers face many design choices-for example, whether participants indicate responses by clicking a button or just by entering the button area. Hitherto, numerous different settings have been employed, but little is known about how these methodological differences affect mouse-tracking data. We systematically investigated the influences of three central design factors, using a classic mouse-tracking paradigm in which participants classified typical and atypical exemplars. In separate experiments, we manipulated the response indication, mouse sensitivity, and starting procedure. The core finding that mouse movements deviate more toward the nonchosen option for atypical exemplars was replicated in all conditions. However, the size of this effect varied. Specifically, it was larger when participants indicated responses via click and when they were instructed to initialize the movement early. Trajectory shapes also differed between setups. For example, a dynamic start led to mostly curved trajectories, responses via click led to a mix of straight and "change-of-mind" trajectories, and responses via touch led to mostly straight trajectories. Moreover, the distribution of curvature indices was classified as bimodal in some setups and as unimodal in others. Because trajectory curvature and shape are frequently used to make inferences about psychological theories, such as differentiating between dynamic and dual-system models, this study shows that the specific design must be carefully considered when drawing theoretical inferences. All methodological designs and analyses were implemented using open-source software and are available from https://osf.io/xdp7a/.

Reconsidering the minimally important difference: evidence of instability over time and across groups

BACKGROUND CONTEXT

Underlying cognitive factors have been found to influence patients' symptom experience. Current evidence suggests that concomitant changes in appraisal must be taken into account to accurately interpret change as measured by standard spine patient-reported outcomes (PROs).

PURPOSE

To investigate changes in patients' minimally important differences (MID) over recovery from spinal surgery; whether and how cognitive appraisal processes are implicated in the change trajectories.

STUDY DESIGN/SETTING

Longitudinal cohort study with up to 12 months follow-up.

PATIENT SAMPLE

Surgical patients (n = 167) with a diagnosis of disc herniation or spinal stenosis.

OUTCOME MEASURES

Standard spine patient-reported PROs were used (Rand-36, Oswestry Disability Index, Numerical Rating Scale for pain, PROMIS Pain Impact).

METHODS

This study was funded by the Feldberg Chair in Spinal Research, Sunnybrook Health Sciences Centre and the authors have no conflicts of interest. MID used an anchor technique and was computed by global assessment of change (GAC) grouping. Participants were binned into groups based on their GAC response patterns at all time points: Consistently better post-surgery, consistently worse post-surgery, and bouncers, whose GAC ratings fluctuate (ie, better-then-worse-then-better; or vice versa). Individuals' longitudinal quality of life (QOL) and appraisal slope scores were computed. QOL-appraisal slopes' correlations were computed by GAC group. Fisher's Z transformation tested the hypothesis that GAC groups differed in the QOL-appraisal relationship over time.

RESULTS

Moderate to large changes are recognized as clinically important in the early stages of recovery (ie, 6 weeks post-surgery), and over time smaller and smaller changes become important. The three pattern groups emphasized and deemphasized different standards of comparison over time, with the Better group emphasizing personal goals and the Worse and Bouncers deemphasizing doctors' input. These group differences translated to differential relationships between PRO change and appraisal changes over time.

CONCLUSIONS

The MID reflects increasingly subtle change over time in PROs. Appraisal may influence how patients experience the same (MID) change over time, with better outcomes associated with emphasizing long-term goals. PRO change seems to be driven by different standards of comparison. Potential avenues for clinical intervention are discussed.

Increased frequency of mind wandering in healthy women using oral contraceptives

Oral contraceptive (OC) is the most common type of contraceptive method used in industrialized countries. A recent epidemiological study showed that OC use was associated with the onset of depression in young women. Mind wandering, a cognitive process associated with spontaneous thoughts unrelated to the task at-hand, has previously been associated with depressive thinking. Consequently, mind wandering might be a precursor for cognitive vulnerability in individuals who are at-risk for mood disorders. The purpose of this study was to examine the frequency and nature of mind wandering in women using OC in comparison to two control groups: naturally cycling women and men. We recruited 71 participants (28 women currently using OC, 14 naturally cycling women in the luteal phase of their menstrual cycle and 29 men) aged between 18 and 35 years, and measured the frequency and nature (guilt/fear oriented and positive) of mind wandering using the short version of the Imaginal Process Inventory. In all analyses, we controlled for depressive symptoms to delineate the unique association between OC use and mind wandering. We also measured estradiol, progesterone and testosterone to confirm expected group differences in sex hormones concentrations. Results show that women using OC presented increased frequency of mind wandering when compared to naturally cycling women and men who did not differ between each other. The three groups did not differ in terms of the nature of mind wandering. These results show that OC use is associated with increased frequency of mind wandering and suggest that the association between OC use and dysphoric mood described in previous studies may be partially explained by the impact of OC use on cognitive processes underlying mind wandering.

Brain functional imaging in obese and diabetic patients

Obesity and type 2 diabetes are associated with greater risk of brain damage. Over the last decade, functional imaging techniques (functional magnetic resonance imaging, fMRI, positron emission tomography, PET, electroencephalography, magnetoencephalography, near infrared spectroscopy) have been exploited to better characterize behavioral and cognitive processes, by addressing cerebral reactions to a variety of stimuli or tasks, including hormones and substrates (e.g., glucose, insulin, gut peptides), environmental cues (e.g., presentation of sensory stimuli), and cognitive tasks. Among these techniques, fMRI and PET are most commonly used, and this review focuses on results obtained with these techniques in relation to brain substrate metabolism, appetite control and food intake, and cognitive decline in obesity and type 2 diabetes. The available knowledge indicates that there are a series of cerebral abnormalities associating with, or preceding obesity and type 2 diabetes, including impaired substrate handling, insulin resistance, disruption of inter-organ cross-talk and of resting state networking. Some of these abnormalities are reversed by metabolic interventions, suggesting that they are partly a consequence rather than cause of disease. Therefore, causal implications and mechanisms remain to be determined.

Goal-directed self-talk used to self-regulate in male basketball competitions

This study examined how goal-directed self-talk may help basketball players to self-regulate in stereotypical competitive situations: seconds before a challenging game, while clearly winning or clearly losing, and at the close of a tight game. Participants were recruited in groups of three to four, until preliminary inspection of the data indicated that data saturation was reached. In the end, 34 basketball players voluntarily took part in individual interviews, writing up to three self-instructions they had used in each of the four competitive situations to self-regulate. Content analyses revealed that self-talk in competitive basketball situations serves cognitive functions (e.g., regulating cognition and behaviour), motivational functions (e.g., promoting mastery goals) and emotion and activation-regulating functions (e.g., creating activated states). More specifically, the results also indicated that athletes' self-talk may serve functions specific to the psychological demands experienced in each situation. It is argued that knowing how athletes counsel themselves, could prove important for applied sport psychologists to design psychological skill training.

Volumetric image interpretation in radiology: scroll behavior and cognitive processes

The interpretation of medical images is a primary task for radiologists. Besides two-dimensional (2D) images, current imaging technologies allow for volumetric display of medical images. Whereas current radiology practice increasingly uses volumetric images, the majority of studies on medical image interpretation is conducted on 2D images. The current study aimed to gain deeper insight into the volumetric image interpretation process by examining this process in twenty radiology trainees who all completed four volumetric image cases. Two types of data were obtained concerning scroll behaviors and think-aloud data. Types of scroll behavior concerned oscillations, half runs, full runs, image manipulations, and interruptions. Think-aloud data were coded by a framework of knowledge and skills in radiology including three cognitive processes: perception, analysis, and synthesis. Relating scroll behavior to cognitive processes showed that oscillations and half runs coincided more often with analysis and synthesis than full runs, whereas full runs coincided more often with perception than oscillations and half runs. Interruptions were characterized by synthesis and image manipulations by perception. In addition, we investigated relations between cognitive processes and found an overall bottom-up way of reasoning with dynamic interactions between cognitive processes, especially between perception and analysis. In sum, our results highlight the dynamic interactions between these processes and the grounding of cognitive processes in scroll behavior. It suggests, that the types of scroll behavior are relevant to describe how radiologists interact with and manipulate volumetric images.

The Cognitive Underpinnings of Option Generation in Everyday Life Decision-Making: A Latent Variable Analysis

The ability to generate options for action is crucial for everyday life decision-making. In this article, we propose and test a model of the cognitive underpinnings of option generation in everyday life situations. We carried out a laboratory study using measures of a wide range of cognitive functions and asked participants (N = 157) to generate options for actions for different everyday life decision-making scenarios. The results of a latent variable analysis show that the cognitive underpinnings of option generation are consistent across different everyday life situations and, hence, option generation can be conceptualized as a general construct. Moreover, the results of a confirmatory factor analysis reveal that, when controlling for the shared variance among the cognitive processes assessed, verbal fluency, working memory capacity, ideation fluency, and processing speed predicted option generation. These findings suggest that option generation in everyday life situations can be distinguished from other cognitive constructs, such as divergent thinking (in terms of ideas' originality) and long-term memory.

Mental imagery in dentistry: Phenomenology and role in dental anxiety

Dental anxiety is a prevalent problem with marked psychological, physical and public health implications. Based on cognitive theory and evidence, we hypothesized that vivid, sensory image-based cognitions play a role in dental anxiety. A quantitative online survey (N = 306) and qualitative semi-structured interviews (N = 18) found that vivid sensory images were common irrespective of dental anxiety levels, but that their content, associated distress and responses varied. Participants reporting higher anxiety experienced intense and intrusive fear-provoking dental imagery focusing on unpleasant sensations, which were associated with the intrusive recollection of negative past experiences and avoidance of dentistry. Participants with lower anxiety ratings, reported images that were less distressing and centered around reassuring aspects and positive appointment outcomes, potentially acting as protective factors against dental anxiety and facilitating appointment attendance. The inclusion of components aimed at reducing intrusive memories and dental imagery rescripting may help improve interventions for dental anxiety.

Evidence for mood-dependent attentional processing in asthma: attentional bias towards health-threat in depressive mood and attentional avoidance in neutral mood

Attentional biases have been observed in populations with psychological disorders, but have been under-investigated in populations with physical illnesses. This study investigated potential attentional biases in asthma as a function of mood. Asthma (N = 45), and healthy (N = 39) participants were randomly allocated to a depressed or a neutral mood state induction. They completed a visual probe task that measured participants’ reaction times to health-threat and neutral pictures and words. Compared to the healthy controls, the asthma group showed attentional bias towards health-threat pictures in depressed mood, and avoidance of health-threat pictures in neutral mood. Attentional biases were found in a group with a physical illness as a function of induced mood. It is suggested that attentional processes in people with physical illness may be important in relation to symptom perception and illness management.

The relationship between schizotypal facets and conspiracist beliefs via cognitive processes

This study sought to replicate previous work showing relationships between components of schizotypy and conspiracist beliefs, and extend it by examining the mediating role of cognitive processes. An international online sample of 411 women and men (mean age = 35.41 years) completed measures of the schizotypal facets of Odd Beliefs or Magical Thinking and Ideas of Reference, conspiracist beliefs, and cognitive processes related to need for cognition, analytic thinking, and cognitive insight. Path analysis confirmed the associations between both schizotypal facets and conspiracist beliefs in the present sample. Confirmatory evidence was found for the association between analytic thinking and conspiracist beliefs, and results also suggested an association between cognitive insight and conspiracist beliefs. Cognitive insight also mediated the link between Odd Beliefs or Magical Thinking and Ideas of Reference with conspiracist beliefs. However, analytic thinking provided a mediating link to conspiracy ideation for Odd Beliefs or Magical Thinking and not Ideas of Reference. Finally, there was an association between Odd Beliefs or Magical Thinking and need for cognition, but this path did not extend to conspiracist beliefs. These results suggest possible mediating roles for analytic thinking and self-certainty between schizotypy and conspiracist beliefs.

Development of a practical outcome measure to account for individual differences in quality-of-life appraisal: the Brief Appraisal Inventory

BACKGROUND

The present study evaluated the distributional and structural characteristics and explanatory power of the 23-item Brief Appraisal Inventory (BAI), a more practical appraisal measure for use in clinical research and practice.

METHODS

A heterogeneous, online cohort of chronic disease patients and caregivers completed the BAI, along with demographics, comorbidities, PROMIS-10, and the Brief NEO Personality Inventory. Principal components, bivariate, and linear and logistic regression analyses addressed BAI item distributions, structure, and construct validity.

RESULTS

The study sample (n = 592) had a mean age of 43.8 (SD = 18.5), and was 79% female. The BAI items exhibited good distributions, and principal component analysis yielded five composite scores: (1) Health Worries; (2) Interpersonal and Independence concerns; (3) Accomplishing Goals and Problem-Solving; (4) Calm, Peaceful, and Active; (5) Spiritual Growth and Altruism. The construct validity of appraisal factors is supported by their zero-order correlations with demographic, health, personality, and health-related QOL measures. Comparisons of appraisal-correlates among comorbidity-burden subgroups shed light on the mediating role that appraisal may play in adapting to chronic illness. Appraisal moderated the influence of comorbidities on emotional but not physical functioning. The performance of the BAI in explaining unique variance in physical and emotional functioning is comparable to results obtained with earlier measures.

CONCLUSIONS

The BAI provides a practical, short tool for evaluating appraisal in a wide range of assessment situations. Future research might utilize the BAI in longitudinal research aimed at detecting response-shift effects over time, and in clinical settings to improve patient-provider communication about concerns related to health, health care, or QOL.

Brain activity patterns induced by interrupting the cognitive processes with online advertising

As a result of the increasing role of online advertising and strong competition among advertisers, intrusive techniques are commonly used to attract web users' attention. Moreover, since marketing content is usually delivered to the target audience when they are performing typical online tasks, like searching for information or reading online content, its delivery interrupts the web user's current cognitive process. The question posed by many researchers in the field of online advertising is: how should we measure the influence of interruption of cognitive processes on human behavior and emotional state? Much research has been conducted in this field; however, most of this research has focused on monitoring activity in the simulated environment, or processing declarative responses given by users in prepared questionnaires. In this paper, a more direct real-time approach is taken, and the effect of the interruption on a web user is analyzed directly by studying the activity of his brain. This paper presents the results of an experiment that was conducted to find the brain activity patterns associated with interruptions of the cognitive process by showing internet advertisements during a text-reading task. Three specific aspects were addressed in the experiment: individual patterns, the consistency of these patterns across trials, and the intra-subject correlation of the individual patterns. Two main effects were observed for most subjects: a drop in activity in the frontal and prefrontal cortical areas across all frequency bands, and significant changes in the frontal/prefrontal asymmetry index.

Nightmares in the general population: identifying potential causal factors

BACKGROUND

Nightmares are inherently distressing, prevent restorative sleep, and are associated with a number of psychiatric problems, but have rarely been the subject of empirical study. Negative affect, linked to stressful events, is generally considered the key trigger of nightmares; hence nightmares have most often been considered in the context of post-traumatic stress disorder (PTSD). However, many individuals with heightened negative affect do not have nightmares. The objective of this study was to identify mechanistically plausible factors, beyond negative affect, that may explain why individuals experience nightmares.

METHOD

846 participants from the UK general population completed an online survey about nightmare occurrence and severity (pre-occupation, distress, and impairment), negative affect, worry, depersonalisation, hallucinatory experiences, paranoia, alcohol use, sleep duration, physical activity levels, PTSD symptoms, and stressful life events. Associations of nightmares with the putative predictive factors were tested controlling for levels of negative affect. Analyses were also repeated controlling for levels of PTSD and the recent occurrence of stressful life events.

RESULTS

Nightmare occurrence, adjusting for negative affect, was associated with higher levels of worry, depersonalisation, hallucinatory experiences, paranoia, and sleep duration (odds ratios 1.25-1.45). Nightmare severity, controlling for negative affect, was associated with higher levels of worry, depersonalisation, hallucinatory experiences, and paranoia (R 2s: 0.33-0.39). Alcohol use and physical activity levels were not associated with nightmares.

DISCUSSION

The study identifies a number of potential predictors of the occurrence and severity of nightmares. Causal roles require testing in future longitudinal, experimental, and treatment studies.

Resilience to health challenges is related to different ways of thinking: mediators of physical and emotional quality of life in a heterogeneous rare-disease cohort

BACKGROUND

We sought to understand what distinguishes people who confront health challenges but still manage to thrive. This study investigated whether resilience helps to explain the impact of health challenges on quality of life (QOL) outcomes, and how resilience relates to appraisal.

METHODS

A web-based survey of rare-disease panel participants included the Centers for Disease Control Healthy Days Core Module, the PROMIS-10, and comorbidities. The QOL Appraisal Profile-v2 assessed cognitive processes underlying QOL. Resilience was operationalized statistically using residual modeling, and hierarchical regressions tested the mediation hypothesis that resilience accounts for a significant amount of the relationship of appraisal to QOL.

RESULTS

The study sample (n = 3,324; mean age 50; 86% female; 90% White) represented a range of diagnostic codes, with cancer and diseases of the nervous system being the most prevalent health conditions. After adjusting for comorbidities (catalysts), resilience was associated with better physical and emotional functioning, and different appraisal processes were associated with better or worse physical or emotional functioning. After controlling for catalysts, 62% of the association of Physical Functioning and 23% of the association between Emotional Functioning and appraisal were mediated by resilience. Physical and emotional resilience comprised some of the same appraisal processes, but physically resilient people were characterized by more appraisal processes than their emotionally resilient counterparts.

CONCLUSIONS

Resilient people employ different appraisal processes than non-resilient people, and these processes differ for physical and emotional outcomes. Resilience was a stronger mediator of the relationship between physical rather than emotional functioning and appraisal.

Distinguishing appraisal and personality influences on quality of life in chronic illness: introducing the quality-of-life Appraisal Profile version 2

BACKGROUND

Cognitive appraisal of quality of life (QOL) differs across individuals in ways that explain otherwise paradoxical findings, such as similar QOL ratings among individuals in highly divergent health states. Although warranted by a growing body of evidence, routine assessment of appraisal in QOL research has been impeded by measurement challenges. This study describes the QOL Appraisal Profile-version 2 (QOLAPv2), a new measure that addresses these challenges.

METHODS

A heterogeneous, on-line cohort of chronic disease patients and caregivers completed the QOLAPv2, along with demographics, PROMIS10 and Brief NEO Personality Inventory (NEO-PI). Analyses address the psychometric properties and construct validity of this new measure using principal components, bivariate, canonical correlation, and linear regression analyses.

RESULTS

Analysis including 4173 respondents yielded 12 second-order QOLAPv2 principal components. Appraisal components varied with age and disease duration. Appraisals involving "Wellness," "Health," and "Recent Challenges" were correlated with QOL and with NEO-PI scales of "Agreeableness" and "Conscientiousness." Canonical correlation analysis revealed that QOL scales were associated with appraisals involving "Spirituality," "Anticipating Decline," and "Lightness of Being." Appraisal dimensions of "Relationships," "Maintaining Roles," "Independence," "Pursuing Dreams," and "Lightness of Being" were also associated with personality scales. Appraisal measures accounted for significantly more variance in QOL than personality and demographics alone.

CONCLUSIONS

Findings corroborate the Rapkin and Schwartz QOL appraisal theory. QOL appraisal measures correlate as expected with personality scales, and explain more variance in QOL than does personality. The QOLAPv2 can be used across populations to provide insight into patients' concerns, salient experiences, and comparators.
