Abstract
Phenomenon: The increase in clinical and teaching workload has brought enormous pressure to clinical teachers. Clinical teachers play an extremely important role in the quality of higher medical education and the cultivation of medical talents. However, few studies have examined the attitudes and practices of clinical teachers regarding the role of teachers in China. This study aimed to investigate clinical teachers' perceptions about their roles and current practices at affiliated hospitals of medical universities in China. Approach: Responses from 312 Chinese clinical teachers were included in the analyses. The data were collected using the questionnaires of perception and practice regarding the role of teachers which consisted of 12 items rated on a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree), and scored by calculating the mean. The data were analyzed using the Statistical Package for Social Sciences, version 22.0 (IBM SPSS Corp). Findings: The mean score of perception of clinical teachers regarding the role of teachers was 4.51 (SD = 0.72), and the mean score of practice was 3.69 (SD = 1.17). Multivariable binary logistic regression model showed that undertaking very few/few clinical teaching workload, 'thinking it is my obligation to carry out teaching work seriously' and 'thinking it is my duty to train medical talents' were not only significant determinants of good perception but also good practice. Additionally, 'thinking hospital attached great importance to clinical teaching' was the significant determinant of good perception. Insights: Chinese clinical teachers demonstrate less positive perception and practice regarding the roles of teacher than clinical teachers in developed countries. Affiliated hospitals of medical universities should hold training sessions regularly and take targeted intervention measures to enhance clinical teachers' perception and practice regarding the roles of teacher.

Abstract
OBJECTIVE To evaluate therapeutic footwear expectations and usability of individuals with diabetes and foot complications. DESIGN A prospective multicenter study was conducted on participants with a high risk of developing a diabetic foot ulcer. SETTING Participants were enrolled in 11 different specialized diabetic foot units in Spain between March 2022 and June 2023. SUBJECTS Patients with diabetes at moderate to high risk of foot ulceration receiving first therapeutic footwear prescription. INTERVENTIONS All the patients included in the research were prescribed with their first pair of therapeutic footwear. MAIN MEASURES Primary outcome measures were MOS-pre and MOS-post questionnaires evaluating use and usability of prescribed therapeutic footwear. Secondary outcome measures aimed to evaluate footwear clinical efficacy as ulceration rate and self-reported perceived walking distance per day. RESULTS The use of therapeutic footwear exceeded the patient's pre-provision prediction of their anticipated use in 94% of people (n = 126). Based on the visual analogic satisfaction scale, the median satisfaction of daily wearing their therapeutic footwear was 7 points, Interquartile Range (IQR) [5-8.25]. During the follow-up period, 39 participants (29.1%) experienced diabetic foot ulcer. Perceived walking distance participants reported an improvement in their perceived walking ability during various daily life activities. CONCLUSIONS Diabetes patients at moderate to high risk of diabetic foot ulcer improved their perception of walking ability after therapeutic footwear prescription. Adherence to the therapeutic footwear prescription resulted in less ulcerations.

Abstract
Controversy exists among collegiate lacrosse about the use of headgear and whether its use will facilitate greater risk compensation by players and thus contribute to unsafe gameplay. We aimed to characterize the attitudes of headgear among women's collegiate lacrosse stakeholders. A total of 190 women's lacrosse stakeholders (players: n = 87; coaches: n = 71; officials: n = 32) participated in this study. Participants completed a survey surrounding attitudes of headgear in women's lacrosse. Descriptives, multiple regressions, and Kruskal-Wallis analyses compared attitudes surrounding headgear among stakeholder groups. Scales of Headgear Affects Play (β = -0.38, p < 0.001) and Sports Development and Safety Practices (β = 0.26, p < 0.05) significantly predicted endorsement on Headgear Safety Attitudes Scale. Among players, Aesthetics (β = 0.51, p < 0.001) and Intention to Wear Headgear (β = 0.31, p < 0.05) predicted endorsement on Headgear Safety Attitudes Scale. Stakeholders did not agree if headgear should be worn in women's lacrosse. Items related to sports development, safety and potential changes in gameplay predicted attitudes to headgear safety among all participants.

Abstract
As people age, they tend to spend more time indoors, and the colours in their surroundings may significantly impact their mood and overall well-being. However, there is a lack of empirical evidence to provide informed guidance on colour choices, irrespective of age group. To work towards informed choices, we investigated whether the associations between colours and emotions observed in younger individuals also apply to older adults. We recruited 7393 participants, aged between 16 and 88 years and coming from 31 countries. Each participant associated 12 colour terms with 20 emotion concepts and rated the intensity of each associated emotion. Different age groups exhibited highly similar patterns of colour-emotion associations (average similarity coefficient of .97), with subtle yet meaningful age-related differences. Adolescents associated the greatest number but the least positively biased emotions with colours. Older participants associated a smaller number but more intense and more positive emotions with all colour terms, displaying a positivity effect. Age also predicted arousal and power biases, varying by colour. Findings suggest parallels in colour-emotion associations between younger and older adults, with subtle but significant age-related variations. Future studies should next assess whether colour-emotion associations reflect what people actually feel when exposed to colour.

Abstract
Ongoing brain activity preceding visual stimulation has been suggested to shape conscious perception. According to the pulsed inhibition framework, bouts of functional inhibition arise in each alpha cycle (every ~100 ms), allowing information to be processed in a pulsatile manner. Consequently, it has been hypothesized that perceptual outcome can be influenced by the specific phase of alpha oscillations prior to the stimulus onset, although empirical findings are controversial. In this study, we aimed to shed light on the role of prestimulus alpha oscillations in visual perception. To this end, we recorded electroencephalographic activity, while participants performed three near-threshold visual detection tasks with different attentional involvement: a no-cue task, a noninformative cue task (50% validity), and an informative cue task (100% validity). Cluster-based permutation statistics were complemented with Bayesian analyses to test the effect of prestimulus oscillatory amplitude and phase on visual awareness. We additionally examined whether these effects differed in trials with low and high oscillatory amplitude, as expected from the pulsed inhibition theory. Our results show a clear effect of prestimulus alpha amplitude on conscious perception, but only when alpha fluctuated spontaneously. In contrast, we did not find any evidence that prestimulus alpha phase influenced perceptual outcome, not even when differentiating between low- and high-amplitude trials. Furthermore, Bayesian analysis provided moderate evidence in favor of the absence of phase effects. Taken together, our results challenge the central theoretical predictions of the pulsed inhibition framework, at least for the particular experimental conditions used here.

Abstract
CONTEXT From 2000 to 2019, drug overdoses, combined intentional and unintentional, were the number one cause of death for Americans under 50 years old,with the number of overdoses increasing every year. Between 2012 and 2018, approximately 85 % of all opioid users obtained their opioids through prescriptions from healthcare providers, predominantly physicians. Increased education about the severity of this issue may increase the likelihood of physicians integrating alternative forms of care such as cognitive behavioral approaches, nonopioid therapies, and nonpharmacologic therapies into treatment plans for chronic pain. OBJECTIVES This study investigates medical students' beliefs, experiences, and perceived impact of opioids at Ohio University Heritage College of Osteopathic Medicine (OU-HCOM) and University of Toledo College of Medicine and Life Sciences (UT). METHODS A total of 377 students from OU-HCOM (years 1-4, n=312) and UT (years 1-2, n=65) were surveyed on their beliefs, experiences, and perceived impact of opioids. Multiple t tests were conducted to compare the difference in perceived severity and stigma between participants who were impacted by the epidemic and those who were not. A Kendall rank test was performed to analyze the relationship between the county drug overdose rate and perceived severity for medical students. p <0.05 defined statistical significance for all statistical tests performed in this study. RESULTS In comparing medical students' personal experiences with the opioid crisis, it was found that many more participants had experiences with an affected classmate or patient (4.1; 95 % CI, 4.0-4.2), as opposed to direct experiences within their family or group of friends (1.9; 95 % CI, 1.8-2.0). However, this group of participants who directly experienced the opioid crisis were found to be more likely to view the crisis as more severe in Ohio's adult population than those without that direct experience (p=0.03, α=0.05). The difference in experience and severity outlook did not make one group of medical students more likely to hold a stigma toward those struggling with opioid addiction (p=0.3, α=0.05). The study did not find a significant relationship between the county drug overdose rate and the perceived severity among medical students (R=0.05, p=0.6, α=0.05). CONCLUSIONS This study gave an insight into the beliefs, experiences, and perceived impact of opioids within a group of 377 medical students. It was shown that differences in background can lead to differences in perception of the crisis. Knowing these differences can lead to beneficial changes in education and curriculum design in medical education.

Abstract
OBJECTIVE Antibiotic resistance (ABR) is a major threat to public health. Hospital healthcare professionals are important stakeholders in curbing ABR. To be able to encourage healthcare professionals to act against ABR, information on their perceptions is needed. Yet, summary evidence on how healthcare professionals perceive ABR causes, consequences, and solutions is outdated. This review aims to elucidate these perceptions. METHODS We searched MEDLINE, EMBASE, PsycINFO, and CINAHL for literature published until July 6th, 2022, and used Web of Science and Scopus to identify reports citing included studies. Reports of quantitative original research from high-income countries were included if they investigated hospital healthcare professionals' perceptions about ABR. Descriptive data and data on perceptions about causes, consequences, and solutions regarding ABR were extracted. PROSPERO registration: CRD42022359249. RESULTS The database search and citation tracking yielded 13,551 and 694 papers respectively. Forty-eight reports from 46 studies were included in the review. These studies were performed between 1999 and 2023 and included between 8 and 1362 participants. Healthcare professionals perceived ABR as a problem that is more severe nationally than locally and they primarily recognize ABR as a distant and abstract problem. Studies mostly concurred on prescribing behavior as a cause and a solution for ABR, while external causes and solutions (e.g., in agriculture) elicited less agreement. CONCLUSIONS Studies with a primary focus on the perceptions of healthcare professionals about ABR are limited. Healthcare professionals perceive prescribing behavior as a major cause of ABR and a focus area for ABR solutions.

Abstract
While perceptual thresholds have been widely studied, VOR thresholds have received less attention, so the relationship between vestibulo-ocular reflex (VOR) and perceptual thresholds remains unclear. We compared the frequency dependence of human VOR thresholds to human perceptual thresholds for yaw head rotation in both upright ("yaw rotation") and supine ("yaw tilt") positions using the same human subjects and motion device. VOR thresholds were generally a little smaller than perceptual thresholds. We also found that horizontal VOR thresholds for both yaw rotation about an earth-vertical axis and yaw tilt (yaw rotation about an earth-horizontal axis) were relatively constant across 4 frequencies (0.2, 0.5, 1 and 2 Hz) with little difference between yaw rotation and yaw tilt VOR thresholds. For yaw tilt stimuli, perceptual thresholds were slightly lower at the lowest frequency and nearly constant at all other (higher) frequencies. However, for yaw rotation, perceptual thresholds increased significantly at the lowest frequency (0.2Hz). We conclude: (i) that VOR thresholds were relatively constant across frequency for both yaw rotation and yaw tilt, (ii) that the known contributions of velocity storage to the VOR likely yielded these VOR thresholds that were similar for yaw rotation and yaw tilt for all frequencies tested, and (iii) that the integration of otolith and horizontal canal signals during yaw tilt when supine contributes to stable perceptual thresholds, especially relative to the low frequency perceptual thresholds recorded during yaw rotation.

Abstract
Reality is fleeting, and any moment can only be experienced once. Rewatching a video, however, allows people to repeatedly observe the exact same moment. We propose that people may fail to fully distinguish between merely observing behavior again (through replay) from that behavior being performed again in the exact same way. Using an assortment of stimuli that included auditions, commercials, and potential trial evidence, we demonstrated through nine experiments (N = 10,412 adults in the United States) that rewatching makes a recorded behavior appear more rehearsed and less spontaneous, as if the actors were simply precisely repeating their actions. These findings contribute to an emerging literature showing that incidental video features, like perspective or slow motion, can meaningfully change evaluations. Replay may inadvertently shape judgments in both mundane and consequential contexts. To understand how a video will influence its viewer, one will need to consider not only its content, but also how often it is viewed.

Abstract
The phenomenon of semantic satiation, which refers to the loss of meaning of a word or phrase after being repeated many times, is a well-known psychological phenomenon. However, the microscopic neural computational principles responsible for these mechanisms remain unknown. In this study, we use a deep learning model of continuous coupled neural networks to investigate the mechanism underlying semantic satiation and precisely describe this process with neuronal components. Our results suggest that, from a mesoscopic perspective, semantic satiation may be a bottom-up process. Unlike existing macroscopic psychological studies that suggest that semantic satiation is a top-down process, our simulations use a similar experimental paradigm as classical psychology experiments and observe similar results. Satiation of semantic objectives, similar to the learning process of our network model used for object recognition, relies on continuous learning and switching between objects. The underlying neural coupling strengthens or weakens satiation. Taken together, both neural and network mechanisms play a role in controlling semantic satiation.

Abstract
Recent evidence suggests that primary sensory cortical regions play a role in the integration of information from multiple sensory modalities. How primary cortical neurons integrate different sources of sensory information is unclear, partly because non-primary sensory input to a cortical sensory region is often weak or modulatory. To address this question, we take advantage of the robust representation of thermal (cooling) and tactile stimuli in mouse forelimb primary somatosensory cortex (fS1). Using a thermotactile detection task, we show that the perception of threshold-level cool or tactile information is enhanced when they are presented simultaneously, compared with presentation alone. To investigate the cortical cellular correlates of thermotactile integration, we performed in vivo extracellular recordings from fS1 in awake resting and anesthetized mice during unimodal and bimodal stimulation of the forepaw. Unimodal stimulation evoked thermal- or tactile- specific excitatory and inhibitory responses of fS1 neurons. The most prominent features of combined thermotactile stimulation are the recruitment of unimodally silent fS1 neurons, non-linear integration features, and response dynamics that favor longer response durations with additional spikes. Together, we identify quantitative and qualitative changes in cortical encoding that may underlie the improvement in perception of thermotactile surfaces during haptic exploration.

Abstract
The perception and neural processing of sensory information are strongly influenced by prior expectations. The integration of prior and sensory information can manifest through distinct underlying mechanisms: focusing on unexpected input, denoted as prediction error (PE) processing, or amplifying anticipated information via sharpened representation. In this study, we employed computational modeling using deep neural networks combined with representational similarity analyses of fMRI data to investigate these two processes during face perception. Participants were cued to see face images, some generated by morphing two faces, leading to ambiguity in face identity. We show that expected faces were identified faster and perception of ambiguous faces was shifted towards priors. Multivariate analyses uncovered evidence for PE processing across and beyond the face-processing hierarchy from the occipital face area (OFA), via the fusiform face area, to the anterior temporal lobe, and suggest sharpened representations in the OFA. Our findings support the proposition that the brain represents faces grounded in prior expectations.

Abstract
OBJECTIVE To determine the perception of surgical patients at Aga Khan University Hospital (AKUH) about the risks related to blood transfusion. The ultimate aim was to influence patients' acceptability of blood transfusion by reducing their fears through effective counselling. BACKGROUND AKUH has a hospital-based blood bank with more than 90% family replacement donation. Many patients perceive blood transfusion as a risky procedure. This survey will help healthcare practitioners in addressing patients' concerns more effectively while counselling them about blood transfusion. METHODS/MATERIALS It was a cross-sectional survey of patients attending anaesthesia clinic at AKUH during the study period. It assessed patients' perception about adverse effects associated with blood transfusion. RESULTS A total of 363 patients were included. Among the participants, 18% considered blood transfusion to be very often or always risky. Blood transfusion related infections were considered most frequently occurring adverse events. Female patients were more concerned about the risks (p = 0.046). CONCLUSION Many patients consider blood transfusion as a high-risk procedure. Healthcare professionals need to understand patient's perceptions and conduct patient counselling accordingly. This will help physicians in addressing patient-specific concerns related to blood transfusion. Improved knowledge is hoped to translate into improvement in transfusion practices at the national level.

Abstract
Neurons in the inferotemporal (IT) cortex respond selectively to complex visual features, implying their role in object perception. However, perception is subjective and cannot be read out from neural responses; thus, bridging the causal gap between neural activity and perception demands independent characterization of perception. Historically, though, the complexity of the perceptual alterations induced by artificial stimulation of IT cortex has rendered them impossible to quantify. To address this old problem, we tasked male macaque monkeys to detect and report optical impulses delivered to their IT cortex. Combining machine learning with high-throughput behavioral optogenetics, we generated complex and highly specific images that were hard for the animal to distinguish from the state of being cortically stimulated. These images, named "perceptograms" for the first time, reveal and depict the contents of the complex hallucinatory percepts induced by local neural perturbation in IT cortex. Furthermore, we found that the nature and magnitude of these hallucinations highly depend on concurrent visual input, stimulation location, and intensity. Objective characterization of stimulation-induced perceptual events opens the door to developing a mechanistic theory of visual perception. Further, it enables us to make better visual prosthetic devices and gain a greater understanding of visual hallucinations in mental disorders.

Abstract
Why do we prefer some singers to others? We investigated how much singing voice preferences can be traced back to objective features of the stimuli. To do so, we asked participants to rate short excerpts of singing performances in terms of how much they liked them as well as in terms of 10 perceptual attributes (e.g.: pitch accuracy, tempo, breathiness). We modeled liking ratings based on these perceptual ratings, as well as based on acoustic features and low-level features derived from Music Information Retrieval (MIR). Mean liking ratings for each stimulus were highly correlated between Experiments 1 (online, US-based participants) and 2 (in the lab, German participants), suggesting a role for attributes of the stimuli in grounding average preferences. We show that acoustic and MIR features barely explain any variance in liking ratings; in contrast, perceptual features of the voices achieved around 43% of prediction. Inter-rater agreement in liking and perceptual ratings was low, indicating substantial (and unsurprising) individual differences in participants' preferences and perception of the stimuli. Our results indicate that singing voice preferences are not grounded in acoustic attributes of the voices per se, but in how these features are perceptually interpreted by listeners.

Abstract
Plant proteins often carry off-notes, necessitating customized aroma addition. In vitro studies revealed protein-aroma binding, limiting release during consumption. This study employs in vivo nose space proton transfer reaction-time-of-flight-mass spectrometry and dynamic sensory evaluation (time intensity) to explore in-mouth interactions. In a lupin protein-based aqueous system, a sensory evaluation of a trained "green" attribute was conducted simultaneously with aroma release of hexanal, nonanal, and 2-nonanone during consumption. Results demonstrated that enlarging aldehyde chains and relocating the keto group reduced maximum perceived intensity (Imax_R) by 71.92 and 72.25%. Protein addition decreased Imax_R by 30.91, 36.84, and 72.41%, indicating protein-aroma interactions. Sensory findings revealed a perceived intensity that was lower upon protein addition. Aroma lingering correlated with aroma compounds' volatility and hydrophobicity, with nonanal exhibiting the longest persistence. In vitro mucin addition increased aroma binding four to 12-fold. Combining PTR-ToF-MS and time intensity elucidated crucial food behavior, i.e., protein-aroma interactions, that are pivotal for food design.

Abstract
Inspired by recent findings in the visual domain, we investigated whether the stimulus-evoked pupil dilation reflects temporal statistical regularities in sequences of auditory stimuli. We conducted two preregistered pupillometry experiments (experiment 1, n = 30, 21 females; experiment 2, n = 31, 22 females). In both experiments, human participants listened to sequences of spoken vowels in two conditions. In the first condition, the stimuli were presented in a random order and, in the second condition, the same stimuli were presented in a sequence structured in pairs. The second experiment replicated the first experiment with a modified timing and number of stimuli presented and without participants being informed about any sequence structure. The sound-evoked pupil dilation during a subsequent familiarity task indicated that participants learned the auditory vowel pairs of the structured condition. However, pupil diameter during the structured sequence did not differ according to the statistical regularity of the pair structure. This contrasts with similar visual studies, emphasizing the susceptibility of pupil effects during statistically structured sequences to experimental design settings in the auditory domain. In sum, our findings suggest that pupil diameter may serve as an indicator of sound pair familiarity but does not invariably respond to task-irrelevant transition probabilities of auditory sequences.

Abstract
AIM Determining patients' perceptions of multiple sclerosis, a disease with varying symptoms and prognosis for each individual, can significantly contribute to directing care and treatment. Metaphors may be an opportunity to determine perceptions of this unique illness experience. The aim of this study was to reveal the perceptions of patients with multiple sclerosis about "multiple sclerosis" through metaphors. METHODS This study was conducted with metaphor analysis technique based on phenomenological method. The sample included 184 patients with multiple sclerosis. Data was collected face-to-face between July 2022 and January 2023. Each participant was interviewed individually and was asked to fill in the blanks in the sentence, "multiple sclerosis is like… because…". Content analysis was performed for metaphors. RESULTS The study revealed five main themes and twelve subthemes that provided insight into the participants' multiple sclerosis perceptions. The themes address (i) Manipulator multiple sclerosis; ambiguous multiple sclerosis, attritive multiple sclerosis, controller multiple sclerosis, demander multiple sclerosis, and conditional multiple sclerosis (ii) Temporal multiple sclerosis; cyclical multiple sclerosis and perpetual multiple sclerosis (iii) Follower multiple sclerosis; unaccepted multiple sclerosis, partner multiple sclerosis and ambusher multiple sclerosis (iv) Different multiple sclerosis; bittersweet multiple sclerosis and unique multiple sclerosis (v) Restorative multiple sclerosis. CONCLUSION This study demonstrated that patients with multiple sclerosis mostly had negative perceptions regarding their relationship with multiple sclerosis. The results place a responsibility on healthcare professionals to improve how patients adapt to multiple sclerosis. This study's results can bridge theoretical knowledge and practice.

Abstract
The purpose of this cross-sectional study is to analyze and perform a model analysis of the scope of caffeine consumption in adolescents in Turkey. The prevalence of caffeine consumption was 65.5% (321/490), with 22% of boys and 38.45% of girls consuming foodstuffs or beverages containing it. The mean daily caffeine intake was 85.8 mg. Girls consumed all types of coffee more frequently, while boys consumed black tea and energy drinks such as Red Bull and Burn more frequently than girls. Coffee was most frequently consumed to boost concentration, and tea and energy drinks out of habit. Individuals who lived in the city center, smokers, and individuals with high income levels consumed more caffeine (P = .000, P = .000, and P = .000). The level at which energy drinks were consumed by mixing with alcohol in a party setting was 11.5%, and this was more common among boys (P = .000). Greater efforts should be made to inform parents and adolescents of the potential harm resulting from misuse of caffeine.

Abstract
BACKGROUND Inertial self-motion perception is thought to depend primarily on otolith cues. Recent evidence demonstrated that vestibular perceptual thresholds (including inertial heading) are adaptable, suggesting novel clinical approaches for treating perceptual impairments resulting from vestibular disease. OBJECTIVE Little is known about the psychometric properties of perceptual estimates of inertial heading like test-retest reliability. Here we investigate the psychometric properties of a passive inertial heading perceptual test. METHODS Forty-seven healthy subjects participated across two visits, performing in an inertial heading discrimination task. The point of subjective equality (PSE) and thresholds for heading discrimination were identified for the same day and across day tests. Paired t-tests determined if the PSE or thresholds significantly changed and a mixed interclass correlation coefficient (ICC) model examined test-retest reliability. Minimum detectable change (MDC) was calculated for PSE and threshold for heading discrimination. RESULTS Within a testing session, the heading discrimination PSE score test-retest reliability was good (ICC = 0. 80) and did not change (t(1,36) = -1.23, p = 0.23). Heading discrimination thresholds were moderately reliable (ICC = 0.67) and also stable (t(1,36) = 0.10, p = 0.92). Across testing sessions, heading direction PSE scores were moderately correlated (ICC = 0.59) and stable (t(1,46) = -0.44, p = 0.66). Heading direction thresholds had poor reliability (ICC = 0.03) and were significantly smaller at the second visit (t(1,46) = 2.8, p = 0.008). MDC for heading direction PSE ranged from 6-9 degrees across tests. CONCLUSION The current results indicate moderate reliability for heading perception PSE and provide clinical context for interpreting change in inertial vestibular self-motion perception over time or after an intervention.

Abstract
In this study, we explored spatial-temporal dependencies and their impact on the tactile perception of moving objects. Building on previous research linking visual perception and human movement, we examined if an imputed motion mechanism operates within the tactile modality. We focused on how biological coherence between space and time, characteristic of human movement, influences tactile perception. An experiment was designed wherein participants were stimulated on their right palm with tactile patterns, either ambiguous (incongruent conditions) or non-ambiguous (congruent conditions) relative to a biological motion law (two-thirds power law) and asked to report perceived shape and associated confidence. Our findings reveal that introducing ambiguous tactile patterns (1) significantly diminishes tactile discrimination performance, implying motor features of shape recognition in vision are also observed in the tactile modality, and (2) undermines participants' response confidence, uncovering the accessibility degree of information determining the tactile percept's conscious representation. Analysis based on the Hierarchical Drift Diffusion Model unveiled the sensitivity of the evidence accumulation process to the stimulus's informational ambiguity and provides insight into tactile perception as predictive dynamics for reducing uncertainty. These discoveries deepen our understanding of tactile perception mechanisms and underscore the criticality of predictions in sensory information processing.

Abstract
Recognising objects is a vital skill on which humans heavily rely to respond quickly and adaptively to their environment. Yet, we lack a full understanding of the role visual information sampling plays in this process, and its relation to the individual's priors. To bridge this gap, the eye-movements of 18 adult participants were recorded during a free-viewing object-recognition task using Dots stimuli1. Participants viewed the stimuli in one of three orders: from most visible to least (Descending), least visible to most (Ascending), or in a randomised order (Random). This dictated the strength of their priors along the experiment. Visibility order influenced the participants' recognition performance and visual exploration. In addition, we found that while orders allowing for stronger priors generally led participants to visually sample more informative locations, this was not the case of Random participants. Indeed, they appeared to behave naïvely, and their use of specific object-related priors was fully impaired, while they maintained the ability to use general, task-related priors to guide their exploration. These findings have important implications for our understanding of perception, which appears to be influenced by complex cognitive processes, even at the basic level of visual sampling during object recognition.

Abstract
BACKGROUND Acute mental health services report high levels of safety incidents that involve both patients and staff. The potential for patients to be involved in interventions to improve safety within a mental health setting is acknowledged, and there is a need for interventions that proactively seek the patient perspective of safety. Digital technologies may offer opportunities to address this need. OBJECTIVE This research sought to design and develop a digital real-time monitoring tool (WardSonar) to collect and collate daily information from patients in acute mental health wards about their perceptions of safety. We present the design and development process and underpinning logic model and programme theory. METHODS The first stage involved a synthesis of the findings from a systematic review and evidence scan, interviews with patients (n=8) and health professionals (n=17), and stakeholder engagement. Cycles of design activities and discussion followed with patients, staff, and stakeholder groups, to design and develop the prototype tool. RESULTS We drew on patient safety theory and the concepts of contagion and milieu. The data synthesis, design, and development process resulted in three prototype components of the digital monitoring tool (WardSonar): (1) a patient recording interface that asks patients to input their perceptions into a tablet computer, to assess how the ward feels and whether the direction is changing, that is, "getting worse" or "getting better"; (2) a staff dashboard and functionality to interrogate the data at different levels; and (3) a public-facing ward interface. The technology is available as open-source code. CONCLUSIONS Recent patient safety policy and research priorities encourage innovative approaches to measuring and monitoring safety. We developed a digital real-time monitoring tool to collect information from patients in acute mental health wards about perceived safety, to support staff to respond and intervene to changes in the clinical environment more proactively.

Abstract
The primary visual cortex (V1) and the superior colliculus (SC) both occupy stations early in the processing of visual information. They have long been thought to perform distinct functions, with the V1 supporting the perception of visual features and the SC regulating orienting to visual inputs. However, growing evidence suggests that the SC supports the perception of many of the same visual features traditionally associated with the V1. To distinguish V1 and SC contributions to visual processing, it is critical to determine whether both areas causally contribute to the detection of specific visual stimuli. Here, mice reported changes in visual contrast or luminance near their perceptual threshold while white noise patterns of optogenetic stimulation were delivered to V1 or SC inhibitory neurons. We then performed a reverse correlation analysis on the optogenetic stimuli to estimate a neuronal-behavioral kernel (NBK), a moment-to-moment estimate of the impact of V1 or SC inhibition on stimulus detection. We show that the earliest moments of stimulus-evoked activity in the SC are critical for the detection of both luminance and contrast changes. Strikingly, there was a robust stimulus-aligned modulation in the V1 contrast-detection NBK but no sign of a comparable modulation for luminance detection. The data suggest that behavioral detection of visual contrast depends on both V1 and SC spiking, whereas mice preferentially use SC activity to detect changes in luminance. Electrophysiological recordings showed that neurons in both the SC and V1 responded strongly to both visual stimulus types, while the reverse correlation analysis reveals when these neuronal signals actually contribute to visually guided behaviors.

Abstract
Interdependence occurs when individuals have a stake in the success or failure of others, such that the outcomes experienced by one individual also generate costs or benefits for others. Discussion on this topic has typically focused on positive interdependence (where gains for one individual result in gains for another) and on the consequences for cooperation. However, interdependence can also be negative (where gains for one individual result in losses for another), which can spark conflict. In this article, we explain when negative interdependence is likely to arise and, crucially, the role played by (mis)perception in shaping an individual's understanding of their interdependent relationships. We argue that, owing to the difficulty in accurately perceiving interdependence with others, individuals might often be mistaken about the stake they hold in each other's outcomes, which can spark needless, resolvable forms of conflict. We then discuss when and how reducing misperceptions can help to resolve such conflicts. We argue that a key mechanism for resolving interdependent conflict, along with better sources of exogenous information, is to reduce reliance on heuristics such as stereotypes when assessing the nature of our interdependent relationships.

Abstract
University education is a leading source of information for dental practitioners. Particular emphasis should be given to determining the extent to which students acquire positive knowledge, attitudes, and practices (KAP) and positive metacompetences beyond the scope of each studied dental discipline. We performed a cross-sectional questionnaire-based study among dentistry students from Romania to assess self-perceived risk of infectious diseases and their KAP on topics related to infectious disease prevention. The surveyed students presented good knowledge regarding personal protective equipment (PPE), and their PPE practices significantly correlated with the perceived usefulness of PPE. Only 45.1% correctly recognized all vaccine-preventable diseases (VPDs), but knowledge regarding VPDs significantly improved with increasing year of study (τb = 0.298, p = 0.001), confirming a positive education effect. Awareness regarding the need for screening for bloodborne viruses is poor; the majority of students had never performed a test for hepatitis C virus infection (HCV) (59.4%) or for human immunodeficiency virus (HIV) infection (60.4%). Furthermore, most respondents incorrectly considered themselves at high or very high risk of acquiring BBV, and perceived risk was inversely correlated with willingness to treat patients with hepatitis B virus (HBV) infection (τb = -0.214, p = 0.018), HCV infection (τb = -0.234, p = 0.013), or HIV infection (τb = -0.242, p = 0.006). This led to 3.0% of respondents stating that they would hypothetically deny dental treatment to a patient with HBV infection, 5.0% for HCV infection, and 10.9% for HIV infection, the proportion being significantly higher for HIV (z = -2.2, p = 0.026). In conclusion, better knowledge is needed among dental students regarding their own vaccination history, screening for bloodborne viruses, accurate estimates for their risk of acquiring bloodborne viruses during routine dental practice, and the existence of post-exposure measures following occupational exposure. Improving student knowledge and awareness could translate into a higher willingness to treat patients with chronic viral infections and into a safer and more inclusive dental practice. We propose an adaptation to the university curriculum to cover these key areas for targeted focus to empower future dental practitioners and to facilitate the improvement of across-discipline metacompetences for infection prevention and control.

Abstract
Fluctuations in brain activity alter how we perceive our body and generate movements but have not been investigated in functional whole-body behaviors. During reactive balance, we recently showed that evoked brain activity is associated with the balance ability in young individuals. Furthermore, in PD, impaired whole-body motion perception in reactive balance is associated with impaired balance. Here, we investigated the brain activity during the whole-body motion perception in reactive balance in young adults (9 female, 10 male). We hypothesized that both ongoing and evoked cortical activity influences the efficiency of information processing for successful perception and movement during whole-body behaviors. We characterized two cortical signals using electroencephalography localized to the SMA: (1) the "N1," a perturbation-evoked potential that decreases in amplitude with expectancy and is larger in individuals with lower balance function, and (2) preperturbation β power, a transient rhythm that favors maintenance of the current sensorimotor state and is inversely associated with tactile perception. In a two-alternative forced choice task, participants judged whether pairs of backward support surface perturbations during standing were in the "same" or "different" direction. As expected, lower whole-body perception was associated with lower balance ability. Within a perturbation pair, N1 attenuation was larger on correctly perceived trials and associated with better balance, but not perception. In contrast, preperturbation β power was higher on incorrectly perceived trials and associated with poorer perception, but not balance. Together, ongoing and evoked cortical activity have unique roles in information processing that give rise to distinct associations with perceptual and balance ability.

Abstract
BACKGROUND Numerous prior opinion papers, administrative electronic health record data studies, and cross-sectional surveys of telehealth during the pandemic have been published, but none have combined assessments of video visit success monitoring with longitudinal assessments of perceived challenges to the rapid adoption of video visits during the pandemic. OBJECTIVE This study aims to quantify (1) the use of video visits (compared with in-person and telephone visits) over time during the pandemic, (2) video visit successful connection rates, and (3) changes in perceived video visit challenges. METHODS A web-based survey was developed for the dual purpose of monitoring and improving video visit implementation in our health care system during the COVID-19 pandemic. The survey included questions regarding rates of in-person, telephone, and video visits for clinician-patient encounters; the rate of successful connection for video visits; and perceived challenges to video visits (eg, software, hardware, bandwidth, and technology literacy). The survey was distributed via email to physicians, advanced practice professionals, and clinicians in May 2020. The survey was repeated in March 2021. Differences between the 2020 and 2021 responses were adjusted for within-respondent correlation across surveys and tested using generalized estimating equations. RESULTS A total of 1126 surveys were completed (511 surveys in 2020 and 615 surveys in 2021). In 2020, only 21.7% (73/336) of clinicians reported no difficulty connecting with patients during video visits and 28.6% (93/325) of clinicians reported no difficulty in 2021. The distribution of the percentage of successfully connected video visits ("Over the past two weeks of scheduled visits, what percentage did you successfully connect with patients by video?") was not significantly different between 2020 and 2021 (P=.74). Challenges in conducting video visits persisted over time. Poor connectivity was the most common challenge reported by clinicians. This response increased over time, with 30.5% (156/511) selecting it as a challenge in 2020 and 37.1% (228/615) in 2021 (P=.01). Patients not having access to their electronic health record portals was also a commonly reported challenge (109/511, 21.3% in 2020 and 137/615, 22.3% in 2021, P=.73). CONCLUSIONS During the pandemic, our health care delivery system rapidly adopted synchronous patient-clinician communication using video visits. As experience with video visits increased, the reported failure rate did not significantly decline, and clinicians continued to report challenges related to general network connectivity and patient access to technology.

Abstract
Background The emergence of COVID-19 pandemic has led to heightened fear and uncertainty among parents of children with cancer. This study was conducted to evaluate the parental perceptions toward effects of COVID-19 infection to children with cancer, determine their stress level and factors contributing to high stress level during the pandemic. Methods This cross-sectional study was conducted in three paediatric oncology centres in Malaysia from September 2020 until December 2022. A total of 167 parents were recruited. Parents completed a set of questionnaires to assess their perception on effect of COVID-19 infection to children with cancer and COVID Stress Scale (CSS) to assess the parents' stress level. Results Patients' mean age at study entry was 8.75 years (SD 4.38). Ninety-one (54.5%) patients were still on active treatment. More than 80% of the parents obtained information regarding COVID-19 infection from mass media and social networking. Fear of their children contracting COVID-19 infection was high especially among patients who were still on treatment. Forty-nine (29.3%) parents were significantly affected by the pandemic leading to loss of job or monthly income. Twenty-nine (17.4%) patients required treatment modification during the pandemic. The median total score for CSS was 78.0 (IQR 25th 64.0; 75th 95.0). Ninety-one (54.5%) respondents were very/extremely stressed based on the CSS scores. Components with high scores were xenophobia (median score 18.0; IQR 25th 13.0, 75th 22.0), fear of danger (median score 17.0; IQR 25th 14.0, 75th 20.0) and contamination fears (median score 16.0; IQR 25th 12.0, 75th 19.0). Lower household income was associated with higher stress level (p = 0.006). Conclusion Our study demonstrated high awareness regarding risk of COVID-19 infection among parents of oncology children. Half of the parents had high stress level, with low household income identified as a factor associated with high stress level.

Abstract
Used cooking oils (UCOs) represent the residual oil and fat used for deep-frying foods. This study determined the perception and practices of food vendors on the reuse and disposal of UCOs. The study aims to provide information on UCO management and its potential environmental impacts. The descriptive cross-sectional study utilized a mixed-method approach. A three-stage sampling technique was applied to select 291 commercial food vendors selling deep-fried foods. The data were collected using interviewer-administered questionnaire, and three focus group discussions. The results showed that 61.0% of the respondents positively perceived the environmental effects of reusing and disposing UCO, and 99.0% repeatedly use the same cooking oil for deep-frying till depletion. The respondents' perception on cooking oil reuse and disposal were influenced by wealth, ethnicity, education, and years of experience. Most respondents demonstrated a positive awareness on the environmental impact of UCO, though a significant gap remained between their knowledge and practice.

Abstract
Background The use of a smartphone built-in microphone for auscultation is a feasible alternative to the use of a stethoscope, when applied by physicians. Objective This cross-sectional study aims to assess the feasibility of this technology when used by parents-the real intended end users. Methods Physicians recruited 46 children (male: n=33, 72%; age: mean 11.3, SD 3.1 y; children with asthma: n=24, 52%) during medical visits in a pediatric department of a tertiary hospital. Smartphone auscultation using an app was performed at 4 locations (trachea, right anterior chest, and right and left lung bases), first by a physician (recordings: n=297) and later by a parent (recordings: n=344). All recordings (N=641) were classified by 3 annotators for quality and the presence of adventitious sounds. Parents completed a questionnaire to provide feedback on the app, using a Likert scale ranging from 1 ("totally disagree") to 5 ("totally agree"). Results Most recordings had quality (physicians' recordings: 253/297, 85.2%; parents' recordings: 266/346, 76.9%). The proportions of physicians' recordings (34/253, 13.4%) and parents' recordings (31/266, 11.7%) with adventitious sounds were similar. Parents found the app easy to use (questionnaire: median 5, IQR 5-5) and were willing to use it (questionnaire: median 5, IQR 5-5). Conclusions Our results show that smartphone auscultation is feasible when performed by parents in the clinical context, but further investigation is needed to test its feasibility in real life.

Abstract
BACKGROUND Digital interventions are increasingly popular for the provision of nonpharmacological pain interventions, but few exist for adolescents with menstrual pain. User-centered design involves incorporating users across phases of digital health intervention design, development, and implementation and leads to improved user engagement and outcomes. A needs assessment is the first step of this approach. OBJECTIVE The goal of this study was to conduct a needs assessment to understand menstrual pain management needs and preferences and mindfulness experiences, preferences, and knowledge of adolescents with menstrual pain to inform the future development of an app for managing menstrual pain. METHODS We used an explanatory sequential mixed method design that included a survey followed by focus groups. Adolescents aged 13-17 years completed a survey (n=111) and participated in focus groups (n=16). Data were analyzed using descriptive statistics and thematic content analysis and synthesized to provide specific recommendations based on adolescent responses. RESULTS Adolescents (n=111) who completed the survey reported a moderate understanding of mindfulness and menstrual pain. Over three-quarters (n=87, 78%) of participants practiced some form of mindfulness and 87% (n=97) of survey participants used nonpharmacological pain management strategies. Teens had a moderate perception that mindfulness could help their menstrual pain (mean 4.51/10, SD 2.45, with higher scores suggesting more interest). Themes were generated related to mindfulness experiences, menstrual pain knowledge and experiences, and app functionality. These themes underscored adolescents' need for continued support and flexible access to mindfulness activities; their awareness of multiple influences to pain, with potential for further education in this area; and the need for menstrual pain-specific content, along with content relevant to typical day-to-day experiences of adolescents. CONCLUSIONS Adolescents with menstrual pain have an interest in using a mindfulness app for pain but have unique needs that need to be addressed to ensure app engagement and relevance for this population. Concrete recommendations for future app development are provided.

Abstract
The biographies of some celebrated artists are marked by accounts that paint a far from beautiful portrait. Does this negative-social knowledge influence the aesthetic experience of an artwork? Does an artist's fame protect their paintings from such an influence? We present two preregistered experiments examining the effect of social-emotional biographical knowledge about famous and unknown artists on the reception and perception of their paintings, using aesthetic ratings and neurocognitive measures. In Experiment 1, paintings attributed to artists characterised by negative biographical information were liked less, evoked greater feelings of arousal and were judged lower in terms of quality, than paintings by artists associated with neutral information. No modulation of artist renown was found. Experiment 2 fully replicated these behavioural results and revealed that paintings by artists associated with negative social-emotional knowledge also elicited enhanced early brain activity related to visual perception (P1) and early emotional arousal (early posterior negativity; EPN). Together, the findings suggest that negative knowledge about famous artists can shape not only explicit aesthetic evaluations, but may also penetrate the perception of the artwork itself.

Abstract
The authors are both self-described congenital aphantasics, who feel they have never been able to have volitional imagined visual experiences during their waking lives. In addition, Loren has atypical experiences of a number of visual phenomena that involve an extrapolation or integration of visual information across space. In this perspective, we describe Loren's atypical experiences of a number of visual phenomena, and we suggest these ensue because her visual experiences are not strongly shaped by inhibitory feedback or by prior expectations. We describe Loren as having Deep Aphantasia, and Derek as shallow, as for both a paucity of feedback might prevent the generation of imagined visual experiences, but for Loren this additionally seems to disrupt activity at a sufficiently early locus to cause atypical experiences of actual visual inputs. Our purpose in describing these subjective experiences is to alert others to the possibility of there being sub-classes of congenital aphantasia, one of which-Deep Aphantasia, would be characterized by atypical experiences of actual visual inputs.

Abstract
Safe autonomous vehicle (AV) operations depend on an accurate perception of the driving environment, which necessitates the use of a variety of sensors. Computational algorithms must then process all of this sensor data, which typically results in a high on-vehicle computational load. For example, existing lane markings are designed for human drivers, can fade over time, and can be contradictory in construction zones, which require specialized sensing and computational processing in an AV. But, this standard process can be avoided if the lane information is simply transmitted directly to the AV. High definition maps and road side units (RSUs) can be used for direct data transmission to the AV, but can be prohibitively expensive to establish and maintain. Additionally, to ensure robust and safe AV operations, more redundancy is beneficial. A cost-effective and passive solution is essential to address this need effectively. In this research, we propose a new infrastructure information source (IIS), chip-enabled raised pavement markers (CERPMs), which provide environmental data to the AV while also decreasing the AV compute load and the associated increase in vehicle energy use. CERPMs are installed in place of traditional ubiquitous raised pavement markers along road lane lines to transmit geospatial information along with the speed limit using long range wide area network (LoRaWAN) protocol directly to nearby vehicles. This information is then compared to the Mobileye commercial off-the-shelf traditional system that uses computer vision processing of lane markings. Our perception subsystem processes the raw data from both CEPRMs and Mobileye to generate a viable path required for a lane centering (LC) application. To evaluate the detection performance of both systems, we consider three test routes with varying conditions. Our results show that the Mobileye system failed to detect lane markings when the road curvature exceeded ±0.016 m-1. For the steep curvature test scenario, it could only detect lane markings on both sides of the road for just 6.7% of the given test route. On the other hand, the CERPMs transmit the programmed geospatial information to the perception subsystem on the vehicle to generate a reference trajectory required for vehicle control. The CERPMs successfully generated the reference trajectory for vehicle control in all test scenarios. Moreover, the CERPMs can be detected up to 340 m from the vehicle's position. Our overall conclusion is that CERPM technology is viable and that it has the potential to address the operational robustness and energy efficiency concerns plaguing the current generation of AVs.

Abstract
The determination of odor threshold values can be performed in various matrices, including air, and serves as a parameter to compare the potencies of odorous compounds. Typically, the odor thresholds in air are determined by gas chromatography-olfactory (GC-O) and referenced to an internal standard, most often (E)-dec-2-enal. Herein, a direct gas chromatography-flame ionization detector-olfactory analysis method for the determination of odor thresholds in air is reported. As model substrates for this novel approach, naturally occurring substances (R)-1-p-menthene-8-thiol as well as (3S,3aS,6R,7aS)-3,6-dimethyl-3a,4,5,6,7,7a-hexahydro-3H-1-benzofuran-2-one were used. The latter compound was synthesized from (-)-isopulegol and exhibited an extremely low odor recognition threshold of 1.9 × 10-6 ng L-1 air, the lowest value reported for a fungal aroma compound thus far.

Abstract
Personal protective equipment (PPE) is a set of tools used by workers to protect all or part of their body against the potential danger of work accidents in the work area. The use of personal protective equipment is often considered unimportant by workers, especially those working in dangerous and risky areas. The discipline of workers in using personal protective equipment is still low, so the risk of work accidents that can endanger workers is quite large. The purpose of this study was to determine the relationship between perception, motivation, knowledge and supervision of the behavior of using PPE at PT. Maruki International Indonesia, Tamalanrea District, Makassar City, South Sulawesi Province. This type of research is analytical research with a cross-sectional study approach with a total sample of 41 people. The results showed that there was a relationship between perceptions and the behavior of using PPE (p = .004), there was a relationship between motivation and behavior in using PPE (p = .002), there was no relationship between knowledge and behavior in using PPE (p = .814), there was a relationship between supervision and usage behavior. PPE (p = .008). It is recommended that workers be obedient and disciplined to use PPE (personal protective equipment) according to the regulations and make it a work norm, provide IEC PPE in all work locations, and increase supervision of the use of PPE through improved management.

Abstract
Humans spend a large proportion of time participating in social interactions. The ability to accurately detect and respond to human interactions is vital for social functioning, from early childhood through to older adulthood. This detection ability arguably relies on integrating sensory information from the interactants. Within the visual modality, directional information from a person's eyes, head, and body are integrated to inform where another person is looking and who they are interacting with. To date, social cue integration research has focused largely on the perception of isolated individuals. Across two experiments, we investigated whether observers integrate body information with head information when determining whether two people are interacting, and manipulated frame of reference (one of the interactants facing observer vs. facing away from observer) and the eye-region visibility of the interactant. Results demonstrate that individuals integrate information from the body with head information when perceiving dyadic interactions, and that integration is influenced by the frame of reference and visibility of the eye-region. Interestingly, self-reported autistics traits were associated with a stronger influence of body information on interaction perception, but only when the eye-region was visible. This study investigated the recognition of dyadic interactions using whole-body stimuli while manipulating eye visibility and frame of reference, and provides crucial insights into social cue integration, as well as how autistic traits affect cue integration, during perception of social interactions.

Abstract
PURPOSE To provide a critical assessment, summarize, and synthesize the evidence from studies using psychometrically validated questionnaires to assess the effects and benefits/barriers of physical exercise in hemodialysis patients. METHODS The search was performed on six electronic databases. It was conducted following the PRISMA statement and the PICO framework. The methodological quality was assessed using the MMAT. Were used the quality criteria for psychometric properties developed by Terwee et al. RESULTS Overall, 70 studies were included, and 39 questionnaires identified, evaluating 13 outcomes. The quality of the psychometric properties of the questionnaires was not always described; only 13 presented positive ratings on > =6/9 properties. The most assessed measure was criterion validity, and the least assessed criteria was responsiveness. The most outcome measured by these questionnaires was quality of life using SF-36, followed by psychological health using the BDI. The DPEBBS was the only instrument identified that assessed the benefits and barriers of exercise. CONCLUSION Quality of life and depression were the most frequent outcomes. Other measures contemplating physical, mental, cognitive performance, and especially of the perceptions benefits and barriers to exercise should be further investigated. We have clearly identified the need for more studies evaluating psychometric measures that have not been tested satisfactorily or hardly been tested at all.

Abstract
Shaking hands is a fundamental form of social interaction. The current study used high-definition cameras during a university graduation ceremony to examine the temporal sequencing of eye contact and shaking hands. Analyses revealed that mutual gaze always preceded shaking hands. A follow up investigation manipulated gaze when shaking hands, and found that participants take significantly longer to accept a handshake when an outstretched hand precedes eye contact. These findings demonstrate that the timing between a person's gaze and their offer to shake hands is critical to how their action is interpreted.

Abstract
Perceptual confidence is thought to arise from metacognitive processes that evaluate the underlying perceptual decision evidence. We investigated whether metacognitive access to perceptual evidence is constrained by the hierarchical organization of visual cortex, where high-level representations tend to be more readily available for explicit scrutiny. We found that the ability of human observers to evaluate their confidence did depend on whether they performed a high-level or low-level task on the same stimuli, but was also affected by manipulations that occurred long after the perceptual decision. Confidence in low-level perceptual decisions degraded with more time between the decision and the response cue, especially when backward masking was present. Confidence in high-level tasks was immune to backward masking and benefitted from additional time. These results can be explained by a model assuming confidence heavily relies on postdecisional internal representations of visual stimuli that degrade over time, where high-level representations are more persistent.

Abstract
Background Conventional physical therapy (CPT) is widely used in clinical practice and known to contribute beneficially to patient's health conditions but remains loosely defined. Research has shown inconsistency in the definition and utilization of CPT among physical therapists in clinical and research settings, limiting its generalisability and reproducibility. Therefore, this study evaluates physical therapists' knowledge, attitudes, and perceptions toward CPT. Methods A cross-sectional study using a self-administered questionnaire containing 36 questions was distributed among 238 licensed physical therapists. Descriptive and inferential statistics were used to measure the physical therapists' knowledge, attitudes, and perceptions towards CPT. Results Physical therapists showed limited knowledge of CPT in rehabilitation (4.09±1.698, 51%). However, the knowledge scores were significantly associated with age (P=0.002), educational levels (P=0.006), and years of work experience (P=0.001). Nevertheless, physical therapists showed an overall positive attitude towards CPT and perceived it as essential to rehabilitation. Conclusion Most physical therapists have low knowledge about CPT but positive attitudes and perceptions. Therefore, customized medical education is necessary to incorporate CPT theories and applications into physical therapists' rehabilitation programs.

Abstract
The diet quality of US adults is poor and cross-sectional analyses suggest self-perception of healthful dietary intake may be overestimated. This analysis assessed the concordance between calculated and perceived diet quality and changes in diet quality among adults seeking weight loss and enrolled in a 12-month randomized behavioral trial. Healthy Eating Index-2015 diet quality (HEI) was calculated from self-administered 24-hour recalls. Perceived diet quality (PDQ) was measured on a 100-point scale. Higher scores indicate better diet quality. Concordance was assessed using the concordance correlation coefficient and Bland-Altman plots. The one hundred and five participants with complete dietary data were mostly female and white. There was good agreement between HEI and PDQ scores at 12 months for less than a third of participants. Most of the disagreement arose from PDQ scores being higher than HEI scores. Even fewer participants had good agreement between HEI changes and PDQ changes. Participants perceived greater improvement in diet quality than indicated by HEI score changes. Concordance was low at 12 months and for change in diet quality. Despite the diet quality of adults seeking weight loss being suboptimal and not improving, many perceived their diet quality and diet quality improvements as better than calculated. Future studies might explore the effect of misperceptions on weight loss outcomes.

Abstract
PURPOSE Long Covid syndrome is a multiorgan condition with multiple sequelae affecting quality of life, capacity to work and daily activities. The advantages that new technologies can offer are presented as an opportunity in the current healthcare framework. OBJECTIVE This research aimed to explore people with Long Covid's experiences with a digital physiotherapy practice intervention, during four weeks. METHODS Qualitative semistructured interviews were conducted by video call. Thirty-two Long Covid participants were invited to join an in-depth interview once the intervention was completed. Participants were queried on their intervention experiences and perceptions, as well as any lifestyle changes made, as a result of receiving digital physiotherapy practice. The interviews were transcribed and analysed using inductive qualitative content analysis. RESULTS In-depth qualitative analysis has revealed four themes that reflect participants' perceptions of digital physiotherapy intervention. The helpfulness of the exercises, interaction with the physiotherapist, the domestic use of technology and the future of digital health practice were the topics highlighted by Long Covid participants. Some improvements have been suggested including video sounds and the need to introduce face-to-face sessions. Participants stated that interventions were helpful and superior to printed exercise sheets, mobile phone apps and usual care received. This intervention did not present major barriers, highlighting the importance of personalized care and continuity in the provision of health services. CONCLUSION The digital physiotherapy practice is perceived by people with Long Covid as an appropriate method for the care of their health needs. Participants stated the need for this type of intervention in the public health system, where it would eliminate waiting lists, facilitate accessibility and improve existing care. PATIENT AND PUBLIC CONTRIBUTION Participants contributed to the interpretation of the data acquired in the interview. CLINICAL TRIAL REGISTRATION Trial registration NCT04742946.

Abstract
Extraneous neuroscience information improves ratings of scientific explanations, and affects mock juror decisions in many studies, but others have yielded little to no effect. To establish the magnitude of this effect, we conducted a random-effects meta-analysis using 60 experiments from 28 publications. We found a mild but highly significant effect, with substantial heterogeneity. Planned subgroup analyses revealed that within-subjects studies, where people can compare the same material with and without neuroscience, and those using text, have stronger effects than between-subjects designs, and studies using brain image stimuli. We serendipitously found that effect sizes were stronger on outcomes of evaluating satisfaction or metacomprehension, compared with jury verdicts or assessments of convincingness. In conclusion, there is more than one type of neuroscience explanations effect. Irrelevant neuroscience does have a seductive allure, especially on self-appraised satisfaction and understanding, and when presented as text.

Abstract
As population-related climate change research increases, so does the need to nuance approaches to this complex phenomenon, including issues related to cultural and linguistic translations. To explore how climate change is understood in understudied societies, a case-study approach is taken to address social representations of climate change by inhabitants of a Maore village in the French island of Mayotte. The study explores how local fishers understand the issue when considering observed environmental changes. Based on analyses of 30 interviews, the study found that social representations and related climate change discourses are not well established, except for individuals in close contact with French institutions. Issues regarding local culture and language reveal the importance of understanding the different components of climate change. Climate change communication and awareness-raising on the island are explored, as well as considerations of culturally and linguistically complex settings with a Global North/Global South interface.

Abstract
The return to social life after a hip fracture is a major concern for patients and a determinant factor in their recovery. However, patients' perceptions of social life after hip fracture are variable and context-dependent. By identifying these perceptions and strategies of patients, interventions can be strengthened and modified. The aim of this study was to identify patients' perceptions of their social life after hip fracture. This qualitative study used inductive content analysis. Twenty patients with hip fractures who were referred to Tehran University of Medical Sciences hospitals were purposefully selected and included in the study. Data were collected through individual, face-to-face, in-depth, semi-structured interviews conducted by a researcher experienced in carrying out such interviews. The interviews were recorded, immediately transcribed verbatim, and analyzed in MAXQDA-10. The interviewing process continued until data saturation was reached. The data analysis led to the extraction of three categories: Disruption of normal social life, Minimal social life, and Social isolation. The results indicated that the social life of these patients is influenced by physical conditions and contextual factors and progresses over time. All patients experienced meaningful disruption of their social life after experiencing hip fractures and movement limitations. The interdisciplinary perspectives provided by these findings can increase awareness of patients' post-fracture social life perceptions and conditions. These findings can also be used to design future programs for interdisciplinary interventions (involving sociology and medical sciences) to improve social life and increase the ability to return to a normal social life. Recovery management for patients with hip fractures should be preventive and organized by an all-around team (involving medicine, psychology, and sociology) based on patient-centered, community-based, and modern care strategies.

Abstract
Tactile perception of softness serves a critical role in the survival, well-being, and social interaction among various species, including humans. This perception informs activities from food selection in animals to medical palpation for disease detection in humans. Despite its fundamental importance, a comprehensive understanding of how softness is neurologically and cognitively processed remains elusive. Previous research has demonstrated that the somatosensory system leverages both cutaneous and kinesthetic cues for the sensation of softness. Factors such as contact area, depth, and force play a particularly critical role in sensations experienced at the fingertips. Yet, existing haptic technologies designed to explore this phenomenon are limited, as they often couple force and contact area, failing to provide a real-world experience of softness perception. Our research introduces the softness-rendering interface (SORI), a haptic softness display designed to bridge this knowledge gap. Unlike its predecessors, SORI has the unique ability to decouple contact area and force, thereby allowing for a quantitative representation of softness sensations at the fingertips. Furthermore, SORI incorporates individual physical fingertip properties and model-based softness cue estimation and mapping to provide a highly personalized experience. Utilizing this method, SORI quantitatively replicates the sensation of softness on stationary, dynamic, homogeneous, and heterogeneous surfaces. We demonstrate that SORI accurately renders the surfaces of both virtual and daily objects, thereby presenting opportunities across a range of fields, from teleoperation to medical technology. Finally, our proposed method and SORI will expedite psychological and neuroscience research to unlock the nature of softness perception.

Abstract
BACKGROUND Experimental research evaluating differences between the visceral and somatic stimulation is limited to pain and typically uses different induction methods for visceral and somatic stimulation (e.g., rectal balloon distention vs. tactile hand stimulation). Our study aimed to compare differences in response time, intensity, unpleasantness, and threat between identical electrical visceral and somatic stimulations at both painful and non-painful perceptual thresholds. METHODS Electrical stimulation was applied to the wrist and distal esophagus in 20 healthy participants. A double pseudorandom staircase determined perceptual thresholds of Sensation, Discomfort, and Pain for the somatic and visceral stimulations, separately. Stimulus reaction time (ms, via button press), and intensity, unpleasantness, and threat ratings were recorded after each stimulus. General linear mixed models compared differences in the four outcomes by stimulation type, threshold, and the stimulation type-by-threshold interaction. Sigmoidal maximum effect models evaluated differences in outcomes across all delivered stimulation intensities. KEY RESULTS Overall, visceral stimulations were perceived as more intense, threatening, and unpleasant compared to somatic stimulations, but participants responded faster to somatic stimulations. There was no significant interaction effect, but planned contrasts demonstrated differences at individual thresholds. Across all delivered intensities, higher intensity stimulations were needed to reach the half-maximum effect of self-reported intensity, unpleasantness, and threat ratings in the visceral domain. CONCLUSIONS AND INFERENCES Differences exist between modalities for both non-painful and painful sensations. These findings may have implications for translating paradigms and behavioral treatments from the somatic domain to the visceral domain, though future research in larger clinical samples is needed.

Abstract
The adoption of precision technologies on dairy farms has increased significantly in recent decades, leading to the challenge of providing employees with resources to maximize the efficient use of these tools. The objective of this study was to explore how dairy farm employees perceive the available precision technologies and to identify possible challenges they face when adapting to their use at the farm. An online survey consisting of four sections (employee demographics, precision technologies in use, perception of these technologies, and opportunities for adapting to technology use) was completed from September to December 2022 by 266 farm employees from three dairies operated under similar management. Most of the respondents were identified as male (72.2%), Hispanic or Latino (92.5%), aged between 21 and 30 (39.1%) or 31 and 40 yr (36.8%), with a bachelor's degree (34.6%) or completion of middle school (29.3%) and having basic or no English proficiency (74%). Overall, the respondents indicated being comfortable (95.6%) with and understanding (91.8%) the technology they use. Employees recognized precision technology as a tool that helps them to be more efficient (93.7%), identifying the technologies' benefits (92.1%). However, challenges for adapting to these technologies included personal limitations, such as not knowing the language of the technology (31%), visual impairments (24%), light sensitivity (14%), and not being able to read (7%). Environmental limitations were also recognized and included cold weather (64.3%), wind (46%), and surroundings that were too dark (31%) or too bright (21%). Significant associations between perception of the technology and age, level of education, and English proficiency were identified. Respondents indicated their desire to learn more about precision technologies implemented at work, which could eventually lead to improved efficiency at the dairy operation through innovations in the way users interact with these technologies, increasing employees' motivation. This study provides insights that could assist the dairy industry in addressing challenges and enhancing opportunities for a more efficient use of precision technologies at dairy farms.
