Sixty Years After Orne's American Psychologist Article: A Conceptual Framework for Subjective Experiences Elicited by Demand Characteristics

Examining conceptual generalisation after acquisition, extinction, and reinstatement in evaluative conditioning

In evaluative conditioning, a neutral conditional stimulus (CS) acquires the valence of a pleasant or unpleasant unconditional stimulus (US) after the CS and US are paired (acquisition). Valence acquired by the CS can generalise to other stimuli from the same category. Presenting the CS alone can reduce evaluative conditioning (extinction), but evaluations can return after the US is presented alone (reinstatement). The current research investigated whether extinction and reinstatement generalise to other category members (generalisation stimuli, GS). In Experiment 1, evaluations generalised in acquisition after conditioning with one category exemplar, but GS evaluations were unaffected by extinction and reinstatement. In Experiment 2, we aimed to enhance generalisation by presenting multiple category exemplars during conditioning. This strengthened the generalisation of evaluations in extinction but not reinstatement. In Experiment 3, conditioning with multiple exemplars caused explicit and implicit evaluations (measured using an affective priming task) to generalise in acquisition but not in extinction or reinstatement. The acquisition and extinction of US expectancy generalised in all experiments, but the reinstatement generalised in Experiment 3 only. Overall, we found partial evidence of evaluative generalisation during extinction (but not reinstatement) and demonstrated that the extinction and reinstatement of US expectancy generalises in evaluative conditioning.

Suspicion About Suspicion Probes: Ways Forward

Suspicion probes are the traditional tool employed to assess the extent to which participants suspect intentional misdirection or deception within the research context. A primary reason psychologists use deception in research settings is to prevent participants from altering their behavior in light of knowing what is being studied, which could undermine internal validity as well as threaten the generalizability of findings to the real world (i.e., external validity). The present article elucidates a number of challenges with suspicion probes. A definition and framework for conceptualizing the construct of suspicion in research settings are proposed. Following a literature review, an analysis of existing evidence, and new data on the prevalence of using and reporting suspicion probes, we conclude that suspicion is a likely problem in research practice. We provide a decision guide to help researchers navigate the numerous choices involved in addressing potential suspicion and call for a combination of (a) renewed research leading to empirically supported tools and best practices and (b) systemic changes to editorial policies, funding practices, professional standards, and research training that would increase rigor and focus on this aspect of research methodology.

Unawareness of Attitudes, Their Environmental Causes, and Their Behavioral Effects

Claims about unawareness are abundant in attitude research. This article provides an analysis of evidence regarding three aspects of an attitude of which people may lack awareness: (a) the attitude itself, (b) its environmental causes, and (c) its behavioral effects. Our analysis reveals that, despite widespread claims of unawareness of the three aspects, strong empirical evidence for these claims is surprisingly scarce. The article concludes with a discussion of the most likely aspects of attitudes that people may be unaware of; their relation to contextual factors that might influence evaluative responses outside of awareness; open questions about the (un)awareness of attitudes, their environmental causes, and their behavioral effects; and methodological recommendations for future research that aims to provide more compelling evidence for aspects of attitudes that may evade awareness.

(Mis)estimation of the modal number of desired sexual partners

Misperceptions of the social world can lead to actions and social policy that are detrimental to an individual's or group's well-being. Here we investigate whether misperceptions arise when participants make predictions of the modal number of ideal future sexual partners reported by heterosexual cohorts (younger cohort: 18-23 years; older cohort: 24-29 years). For both men and women and in both cohorts, the modal number of reported partners equaled 1.0, but men's averages were higher than women's averages due to a subgroup of men who reported desiring large numbers of partners (that is, the distributions had the same shape, but men's distributions had a longer tail). Study 1: When asked to estimate the mode directly, participants performed poorly and, in some conditions, dramatically so (e.g., 40% of younger men reported wanting one sexual partner, but 0% of younger men predicted 1 to be the most frequent response). Study 2: When asked to estimate the shape of the whole distribution, participants underestimated the number of respondents who would desire the mode and thus replicated patterns in the literature for misestimations of skewed distributions. Study 3: When provided information about others' actual modal desired number of partners, the number of male participants who reported desiring one sexual partner increased, suggesting that misperceptions of social norms may influence preferences. We discuss how the mean and mode can lead to two accurate but different interpretations of the data (mean: men report desiring more sexual partners than women; mode: the most frequent response reported by both men and women is 1.0). Discrepancies of this sort can lead to mischaracterizations that may not be uncommon in the research literature. These discrepancies cannot be differentiated by significance tests that seek to find differences in the mean but can be resolved with attention to other methods of analyses.

Deciphering pain: molecular mechanisms and neurochemical pathways-challenges and future opportunities

This review delves into the intricate biological underpinnings of pain perception. It encompasses nociceptive signaling pathways, the molecular mechanisms involved, and the subjective experience of discomfort in humans. The initial focus is on nociceptor transduction, where specialized neurons transform noxious stimuli into electrical impulses. Subsequently, the review explores the central nervous system, elucidating how these signals are processed and modulated by critical elements such as ion channels, receptors, and neurotransmitters (e.g., substance P, glutamate, GABA). Shifting gears toward chronic pain, the review examines the concept of neuroplasticity, highlighting its potential to induce maladaptive responses through alterations in neural networks. The burgeoning field of pain genomics, alongside established genetic research, offers valuable insights that could pave the way for a framework of personalized pain management strategies. Finally, the review emphasizes the significance of these molecular insights in facilitating accurate therapeutic interventions. The overarching objective is to establish an integrative framework for precision medicine in pain management by incorporating this information alongside biopsychosocial models. This framework serves to translate the heterogeneous landscape of pain mechanisms into a coherent roadmap for the development of effective therapies.

The Game Within the Game: The Potential Influence of Demand Characteristics and Participant Beliefs in Violent Video Game Studies

In two experiments, we examined the potential impact of demand characteristics in violent video game (VVG) research. Study 1 (N = 788) measured behavioral aggression, while Study 2 (N = 1,182) measured trait aggression. Participants were informed either that researchers wanted to confirm that VVGs increase aggression ("Positive Hypothesis") or that VVGs have no effect ("Null Hypothesis"). Study 2 included a third condition where participants were given no information. In both studies, the interaction between VVG exposure and experimental conditions was significant. Whereas VVG exposure was significantly positively associated with aggression in the "Null Hypothesis" condition, it was not in the "Positive Hypothesis" condition. These effects were driven by habitual players responding differently based on the presented hypothesis, appearing less aggressive in the "Positive Hypothesis" condition than in the other two conditions. These findings highlight the importance of addressing demand characteristics in VVG studies.

A call to action: Re-activating the latent human factor for achieving the UN SDGs-cultivating courageous partnerships and compassionate human systems

The raison d'être for psychotherapy1 is to address individual suffering and distress. The sustainable development goals address suffering and distress on a global scale in the context of threats to the survival of our communities and planet.

OBJECTIVE

We propose scaling up therapeutic principles for collective impact and nurturing therapist commitment beyond the therapy room, to activate and sustain compassion-in-action at the community system level.

DESIGN

The SDGs represent the strength of collective human concern and action coming together. At the half-way point, we are falling dangerously short of our targets, requiring an urgent response. The tenet of this paper is that the weakest link in our journey is not technical capability or finances, or even the impact of multiple intersecting crises, but our ability to collaborate for sustained action-it is the human factor-hence, we need a psychologically informed response.

METHOD

Notably, least 'visible' is SDG17, the umbrella goal designated means of implementation, through partnership. Partnership has been treated as a transactional element of SDG projects, rather than the vital heartbeat connecting daily actions to the 2030 vision. Partnership is about investing in relationships and a commitment to working together with a common purpose-the bailiwick of psychological therapists.

RESULTS

We propose an architecture to support the development of courageous partnerships and compassionate systems.

CONCLUSION

Compassion uniquely potentiates global action on wicked problems.

Visual imagery vividness correlates with afterimage conscious perception

Afterimages are illusory, visual conscious perceptions. A widely accepted theory is that afterimages are caused by retinal signaling that continues after the physical disappearance of a light stimulus. However, afterimages have been reported without preceding visual, sensory stimulation (e.g. conditioned afterimages and afterimages induced by illusory vision). These observations suggest the role of top-down brain mechanisms in afterimage conscious perception. Therefore, some afterimages may share perceptual features with sensory-independent conscious perceptions (e.g. imagery, hallucinations, and dreams) that occur without bottom-up sensory input. In the current investigation, we tested for a link between the vividness of visual imagery and afterimage conscious perception. Participants reported their vividness of visual imagery and perceived sharpness, contrast, and duration of negative afterimages. The afterimage perceptual features were acquired using perception matching paradigms that were validated on image stimuli. Relating these perceptual reports revealed that the vividness of visual imagery positively correlated with afterimage contrast and sharpness. These behavioral results support shared neural mechanisms between visual imagery and afterimages. However, we cannot exclude alternative explanations, including demand characteristics and afterimage perception reporting inaccuracy. This study encourages future research combining neurophysiology recording methods and afterimage paradigms to directly examine the neural mechanisms of afterimage conscious perception.

Feeling more neutral? Evaluative conditioning can increase neutral affective reactions

ABSTRACTWhile it is important to learn what is good and bad, can people learn what is neither? The answer to this question is not readily apparent, but it has important implications for how people learn affective responses. Six experiments examined whether evaluative conditioning (EC) can instill neutral affect. They tested four hypotheses: EC, in which novel conditioned stimuli (CSs) are paired with neutral unconditioned stimuli (USs) (1) creates neutral affect, (2) forms stronger experiences of neutrality when the number of contingent CS-US pairings is high rather than low, (3) creates positive affect, due to mere exposure, and (4) forms responses that are distinct from no US pairings. Respondents rated how positive, negative, and neutral they felt about a CS before and after an EC task in which CSs were paired with USs (positive, negative, neutral, or no stimuli). The positive/negative US conditions increased/decreased positivity, decreased/increased negativity, and decreased neutrality ratings, respectively. Supporting hypotheses 1, 2, and 4, the neutral US, but not the no US, condition increased neutral evaluations when respondents experienced a high (vs. low) number of CS-US pairings. Hypothesis 3 was not supported. The results reveal that people learn not only valenced, but also neutral, preferences.

Truthfulness as the basis for ethical safeguards in deceptive research: An interview study with researchers

Ethical safeguards such as debriefing are often recommended or required for research studies in which participants are deceived. However, existing guidance on these safeguards seems insufficiently coherent and precise, which may be associated with their suboptimal implementation in practice. This study aimed to contribute to a more coherent and precise framework of ethical safeguards in deceptive studies through semi-structured interviews with a diverse sample of 24 researchers who had significant experience with deception. Interviewees discussed which ethical safeguards they implemented and how, as well as their relation to the notion of truthfulness (i.e., the intentional communication of true information). Moreover, interviewees provided a variety of reasons for and against implementing these safeguards, as well as how these reasons varied with the particular context of a study. Overall, the current study contributes to a more coherent and precise understanding of ethical safeguards in deceptive research that could be useful for guiding researchers and ethics reviewers in their ethical decision-making, although certain imprecisions and incoherent aspects remain in need of further investigation and normative reflection.

Liking music with and without sadness: Testing the direct effect hypothesis of pleasurable negative emotion

Negative emotion evoked in listeners of music can produce intense pleasure, but we do not fully understand why. The present study addressed the question by asking participants (n = 50) to self-select a piece of sadness-evoking music that was loved. The key part of the study asked participants to imagine that the felt sadness could be removed. Overall participants reported performing the task successfully. They also indicated that the removal of the sadness reduced their liking of the music, and 82% of participants reported that the evoked sadness also adds to the enjoyment of the music. The study provided evidence for a "Direct effect hypothesis", which draws on the multicomponent model of emotion, where a component of the negative emotion is experienced as positive during music (and other aesthetic) experiences. Earlier evidence of a mediator, such as 'being moved', as the source of enjoyment was reinterpreted in light of the new findings. Instead, the present study applied a semantic overlap explanation, arguing that sadness primes emotions that share meaning with sadness, such as being-moved. The priming occurs if the overlap in meaning is sufficient. The degree of semantic overlap was defined empirically. The present study therefore suggests that mediator-based explanations need to be treated with caution both as a finding of the study, and because of analytic limitations in earlier research that are discussed in the paper.

Heart is deceitful above all things: Threat expectancy induces the illusory perception of increased heartrate

It has been suggested that our perception of the internal milieu, or the body's internal state, is shaped by our beliefs and previous knowledge about the body's expected state, rather than being solely based on actual interoceptive experiences. This study investigated whether heartbeat perception could be illusorily distorted towards prior subjective beliefs, such that threat expectations suffice to induce a misperception of heartbeat frequency. Participants were instructed to focus on their cardiac activity and report their heartbeat, either tapping along to it (Experiment 1) or silently counting (Experiment 2) while ECG was recorded. While completing this task, different cues provided valid predictive information about the intensity of an upcoming cutaneous stimulation (high- vs. low- pain). Results showed that participants expected a heart rate increase over the anticipation of high- vs. low-pain stimuli and that this belief was perceptually instantiated, as suggested by their interoceptive reports. Importantly, the perceived increase was not mirrored by the real heart rate. Perceptual modulations were absent when participants executed the same task but with an exteroceptive stimulus (Experiment 3). The findings reveal, for the first time, an interoceptive illusion of increased heartbeats elicited by threat expectancy and shed new light on interoceptive processes through the lenses of Bayesian predictive processes, providing tantalizing insights into how such illusory phenomena may intersect with the recognition and regulation of people's internal states.

The relevance of syntactic complexity for truth judgments: A registered report

Fluency theories predict higher truth judgments for easily processed statements. We investigated two factors relevant for processing fluency: repetition and syntactic complexity. In three online experiments, we manipulated syntactic complexity by creating simple and complex versions of trivia statements. Experiments 1 and 2 replicated the repetition-based truth effect. However, syntactic complexity did not affect truth judgments although complex statements were processed slower than simple statements. This null effect is surprising given that both studies had high statistical power and varied in the relative salience of syntactic complexity. Experiment 3 provides a preregistered test of the discounting explanation by using improved trivia statements of equal length and by manipulating the salience of complexity in a randomized design. As predicted by fluency theories, simple statements were more likely judged as true than complex ones, while this effect was small and not moderated by the salience of complexity.

People underestimate the influence of repetition on truth judgments (and more so for themselves than for others)

People judge repeated statements as more truthful than new statements: a truth effect. In three pre-registered experiments (N = 463), we examined whether people expect repetition to influence truth judgments more for others than for themselves: a bias blind spot in the truth effect. In Experiments 1 and 2, using moderately plausible and implausible statements, respectively, the test for the bias blind spot did not pass the significance threshold set for a two-step sequential analysis. Experiment 3 considered moderately plausible statements but with a larger sample of participants. Additionally, it compared actual performance after a two-day delay with participants' predictions for themselves and others. This time, we found clear evidence for a bias blind spot in the truth effect. Experiment 3 also showed that participants underestimated the magnitude of the truth effect, especially so for themselves, and that predictions and actual truth effect scores were not significantly related. Finally, an integrative analysis focusing on a more conservative between-participant approach found clear frequentist and Bayesian evidence for a bias blind spot. Overall, the results indicate that people (1) hold beliefs about the effect of repetition on truth judgments, (2) believe that this effect is larger for others than for themselves, (3) and underestimate the effect's magnitude, and (4) particularly so for themselves.

Disentangling affect from self-esteem using subliminal conditioning

Across three experiments, participants underwent conditioning sequences where the self-referential term I AM (Conditioned Stimulus, or CS+) or a scrambled counterpart M IA (CS-) was paired with either neutral (Unconditioned Stimulus, or US-) or positive attributes (US+). CS and US were presented under subliminal and/or visible conditions. A normalized indicator of affective shift and an explicit self-esteem measure were deployed as outcome measures. In Experiment 1 (N = 60), subliminal CS+ followed by visible US+ produced a significant affective shift only. Experiment 2 (N = 59) presented CS and US under subliminal conditions, which did not influence either outcome measure. In Experiment 3 (N = 60), visible CS appeared with visible US, which resulted in a significant effect on explicit self-esteem only. These findings highlight the central roles of CS and/or US visibility towards influencing reported affect and self-esteem. We theorize that configural components of subliminally presented stimuli can become perceptually encoded and influence self-related affect non-consciously.

Evaluative Conditioning: Past, Present, and Future

Evaluative conditioning (EC) research investigates changes in the evaluation of a stimulus after co-occurrence with an affective stimulus. To explain the motivation behind this research, this review begins with an overview of the history of EC research, followed by a summary of the state of the art with respect to three key questions. First, how should EC procedures be used to influence evaluation? We provide a guide based on evidence concerning the functional properties of EC effects. Second, how does the EC effect occur? We discuss the possible mediating cognitive processes and their automaticity. Third, are EC effects ubiquitous outside the lab? We discuss the evidence for the external validity of EC research. We conclude that the most important open questions pertain to the relevance of EC to everyday life and to the level of control that characterizes the processes that mediate the EC effect after people notice the stimulus co-occurrence.
