This experiment compared the effects of exposure to masked phobic stimuli at a very brief stimulus-onset asynchrony on spider-phobic and non-phobic individuals. Participants were identified through a widely used questionnaire and a Behavioral Avoidance Test with a live, caged tarantula to establish baseline levels of avoidance. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. Preliminary masking experiments showed that independent samples of participants from the same populations failed to (...) recognize these stimuli. Participants in the main experiment reported ratings of subjective distress immediately before and after the exposure manipulation. Then they engaged in the BAT once again. Very brief exposure to images of spiders reduced phobic participants’ avoidance of the tarantula. No effects were evidenced on subjective distress, or on non-phobic participants. Theoretical implications for the non-conscious basis of fear are discussed. (shrink)

A series of experiments tested the hypothesis that very brief exposure to feared stimuli can have positive effects on avoidance of the corresponding feared object. Participants identified themselves as fearful of spiders through a widely used questionnaire. A preliminary experiment showed that they were unable to identify the stimuli used in the main experiments. Experiment 2 compared the effects of exposure to masked feared stimuli at short and long stimulus onset asynchronies . Participants were individually administered one (...) of three continuous series of backwards masked or non-masked stimuli: unreportable images of spiders , clearly visible images of spiders , or unreportable images of trees . Immediately thereafter, they engaged in a Behavioral Avoidance Test with a live, caged tarantula. Exposure to unreportable images of spiders resulted in greater approach towards the tarantula than unreportable neutral images. A post-hoc comparison with clearly visible exposure to these same images approached significance. These effects were maintained at a 1-week follow-up . In Experiment 3 , participants engaged in the BAT 1 week prior to the exposure manipulation in order to provide a baseline measurement of their avoidant behavior, and again immediately after the exposure manipulation. Exposure to unreportable images of spiders reduced avoidance of the tarantula. Similar exposure to trees did not. Implications for the non-conscious basis of fear are discussed. (shrink)

The mere exposure effect is the increase in positive affect that results from the repeated exposure to previously novel stimuli. We sought to determine if judgments other than affective preference could reliably produce a mere exposure effect for two-dimensional random shapes. In two experiments, we found that brighter and darker judgments did not differentiate target from distracter shapes, liking judgments led to target selection greater than chance, and disliking judgments led to distracter selection greater than chance. These results for (...) brighter, darker, and liking judgments were obtained regardless of whether shape recognition was greater (Experiment 1) or not greater (Experiment 2) than chance. Effects of prior exposure to novel shapes were reliably observed only for affective judgment tasks. These results are inconsistent with general predictions made by the nonspecific activation hypothesis, but not the affective primacy or perceptual fluency hypotheses which were discussed in terms of cognitive neuroscience research.

Prior research suggests that visual features of the classroom environment (e.g., charts and posters) are potential sources of distraction hindering children's ability to maintain attention to instructional activities and reducing learning gains in a laboratory classroom. However, prior research only examined short‐term exposure to elements of classroom décor, and it remains unknown whether children habituate to the visual environment with repeated exposure. In study 1, we explored experimentally the possibility that children may habituate to the visual environment if the (...) visual displays are static. We measured kindergarten children's patterns of attention allocation in a decorated classroom environment over a 2‐week period and compared the percentage of time children spent off‐task to a baseline condition in which the classroom environment was streamlined (i.e., charts, posters, and manipulatives were removed). The findings indicate that with more prolonged exposure to a static visual environment, partial habitation effects were observed: Attention to the environment declined at the end of the exposure period compared to the beginning of the study; however, the environment remained a significant source of off‐task behavior even after 2 weeks of exposure. In study 2, we extend this work by conducting a longitudinal observation of six primary classrooms in which we measured children's patterns of attention allocation in real classrooms for 15 weeks to investigate whether increasing familiarity with the classroom décor would influence attention toward the visual environment. No evidence of habituation was observed in genuine classrooms in study 2. Potential implications for classroom design and future directions are discussed. (shrink)

Fast and accurate recognition of teammates is crucial in contexts as varied as fast-moving sports, the military, and law enforcement engagements; misrecognition can result in lost scoring opportunities in sport or friendly fire in combat contexts. Initial studies on teammate recognition in sport suggests that athletes are adept at this perceptual ability but still susceptible to errors. The purpose of the current proof-of-concept study was to explore the trainability of teammate recognition from very brief exposure to vision of the (...) whole-body form and motion of a previously unknown individual. Participants were divided into three groups: a 4-week training group who were also the actors for the test and training footage, a 2-week training group, and a no-training group. Findings revealed significant differences between the training groups and their improvement from the pre-to post-test on Response Accuracy and Movement Time. The current study found the best performance in the 4-week Training group. The biggest improvement was found in the 2-week training group, whilst no significant improvement was made in the Control group. These results suggest that training was effective, but also indicate that having initially performed the movements as actors may have led to improvements in baseline testing and ultimately the best results, thus physical performance of skills combined with video-based training may reduce the amount of time needed to improve teammate identification.

We previously showed that the illusory sense of ownership and agency over a moving body in immersive virtual reality can trigger subjective and physiological reactions on the real subject’s body and, therefore, an acute improvement of cognitive functions after a single session of high-intensity intermittent exercise performed exclusively by one’s own virtual body, similar to what happens when we actually do physical activity. As well as confirming previous results, here, we aimed at finding in the elderly an increased improvement after (...) a longer virtual training with similar characteristics. Forty-two healthy older subjects completed a parallel-group randomized controlled trial including an adapted version of the virtual training previously used: while sitting, participants observed the virtual body in a first-person perspective or a third-person perspective performing 20 min of virtual high-intensity intermittent exercise. This was repeated twice a week for 6 weeks. During the vHIE, we measured the heart rate and administered questionnaires to evaluate illusory body ownership and agency. Before the beginning of the intervention, immediately after the first session of vHIE, and at the end of the entire intervention, we evaluated the cognitive performance at the Stroop task with online recording of the hemodynamic activity over the left dorsolateral prefrontal cortex. While we confirm previous results regarding the virtual illusion and its physiological effects, we did not find significant cognitive or neural improvement immediately after the first vHIE session. As a novelty, in the 1PP group only, we detected a significant decrease in the response time of the Stroop task in the post-intervention assessment compared to its baseline; coherently, we found an increased activation on left dorsolateral prefrontal cortex after the entire intervention. While the current results strengthen the impact of the virtual full-body illusion and its physiological consequences on the elderly as well, they might have stronger and more established body representations. Perhaps, a longer and increased exposure to those illusions is necessary to initiate the cascade of events that culminates to an improved cognitive performance. (shrink)

In three studies, factors influencing the incidence of fraudulent financial reporting were assessed. We examined (1) the effects of personal values and (2) codes of corporate conduct, on whether managers misrepresented financial reports. In these studies, executives and controllers were asked to respond to hypothetical situations involving fraudulent financial reporting procedures. The occurrence of fraudulent reporting was found to be high; however, neither personal values, codes of conduct, nor the interaction of the two factors played a significant role in (...) fraudulent financial reporting.

Arguments about the effects of repeated exposure to a suspenseful narrative raise controversial disputes over the paradox of suspense. The lexical meaning and theoretical analyses of suspense imply that suspense cannot be experienced repeatedly because, in such cases, the knowledge from prior viewings and the resolution of outcome will eliminate tension and suspense. However, previous studies have argued that suspense can be re-experienced even when the participants know the outcome or repeatedly confront a suspenseful narrative. This study investigated (...) the effects of repeated exposure to a suspenseful film by collecting self-reported questionnaires and measuring psychophysiological responses. The participants (N = 50) watched clips of a suspenseful film three times and answered self-reported items regarding suspense, arousal, and enjoyment. Psychophysiological data, including skin conductance level (SCL) and electrocardiogram (ECG), were collected while the participants watched the video clips. It was hypothesized that self-reported suspense, arousal, and enjoyment as well as the physiological indices of arousal (SCL) and attention (ECG) would decrease upon repeated viewing of suspenseful clips. Furthermore, it was postulated that there would be inter-group differences depending on the awareness of potential or definite change in outcome at the end of repeatedly shown suspenseful events. The results showed that self-reported suspense and arousal, as well as physiological measures of SCL, declined with repeated exposure, although there were no significant differences on self-reported enjoyment. No group difference was found in self-reported items, but meaningful significant changes were observed in the group comparison of SCL and ECG. The findings suggest that repeated exposure to suspenseful films could result in affective habituation or desensitization to repeated stimuli. The implications and limitations of the current study and suggestions for future research are discussed. (shrink)

The mere exposure phenomenon (repeated exposure to a stimulus is sufficient to improve attitudes toward that stimulus) is one of the most inspiring phenomena associated with Robert Zajonc’s long and productive career in social psychology. In the first part of this article, Richard Moreland (who was trained by Zajonc in graduate school) describes his own work on exposure and learning, and on the relationships among familiarity, similarity, and attraction in person perception. In the second part, Sascha Topolinski (a recent (...) graduate who never met Zajonc, but found his ideas inspirational) describes his own work concerning embodiment and fluency in the mere exposure effect. Also, several avenues for future research on the mere exposure phenomenon are identified, further demonstrating its continuing relevance to the field. (shrink)

One fundamental assumption often made in the literature on unawareness is that risk preferences are invariant to changes of awareness. We study how exposure to unawareness affects choices under risk. Participants in our experiment choose repeatedly between varying sure outcomes and a lottery in three phases. All treatments are exactly identical in phase 1 and phase 3, but differ in phase 2. There are five different treatments pertaining to the lottery faced in phase 2: The control treatment, the treatment with (...) awareness of unawareness of lottery outcomes but known number of outcomes, the treatment with awareness of unawareness of outcomes but with unknown number of outcomes, the treatment with unawareness of unawareness of some outcomes, and the treatment with an ambiguous lottery. We study both whether behavior differs in phase 3 across treatments and whether differences of subjects’ behavior between phases 1 and phase 3 differ across treatments. We observe no significant treatment effects. (shrink)

This paper investigates the effect of the countervailing forces within organizations of formal systems that direct employees toward ethical acts and informal systems that direct employees toward fraudulent behavior. We study the effect of these forces on deception, a key component of fraud. The results provide support for an interactive effect of these formal and informal systems. The effectiveness of formal systems is greater when there is a strong informal “push” to do wrong; conversely, in the absence of a strong (...) push to do wrong, the strength of formal systems has little impact on fraudulent behavior. These results help to explain why the implementation of formal systems within organizations has been met with mixed results and identifies when formal systems designed to promote ethical behavior will be most efficacious.

Repetition learning is an efficient way to enhance memory performance in our daily lives and educational practice. However, it is unclear to what extent repetition or multiple exposures modulate different types of memory over time. The inconsistent findings on it may be associated with encoding strategy. In this study, participants were presented with pairs of pictures once or three times and were asked to make a same/similar/different judgment. By this, an elaborative encoding is more required for the “same” and (...) “similar” conditions than the “different” condition. Then after intervals of 10 min, 1 day, and 1 week, they were asked to perform a recognition test to discriminate a repeated and a similar picture, followed by a remember/know/guess assessment and a contextual judgment. The results showed that after learning the objects three times, both item memory and contextual memory improved. Multiple exposures enhanced the hit rate for the “same” and “similar” conditions, but did not change the false alarm rate significantly. The recollection, rather than the familiarity, contributed to the repetition effect. In addition, the memory enhancement was manifested in each encoding condition and retention interval, especially for the “same” condition and at 10-min and 1-day intervals. These results clarify how repetition influences item and contextual memories during discriminative learning and suggest that multiple exposures render the details more vividly remembered and retained over time when elaborative encoding is emphasized.

Transcranial magnetic stimulation (TMS) of the visual cortex can induce phosphenes as can non-diagnostic ultrasound, the latter while participants have closed their eyes during Stimulation. Here we sought to study potential alteration of a visual target (a white crosshair) due to application of diagnostic ultrasound to the visual cortex. We applied a randomized series of actual or sham diagnostic ultrasound to the visual cortex of healthy participants while they stared at a visual target, with the ultrasound device placed where TMS (...) elicited phosphenes. These participants observed percepts 7 out of 10 times, consisting of extra or extensions of lines relative to the original crosshair, and additional colors. Observation of a percept occurred an average of 53.7 +/- 2.6% of the time over the course of the experiment for these participants. In contrast, 7 out of 10 participants exposed to sham-only diagnostic ultrasound observed comparable percepts an average of 36.3 +/ 1.9% of the time, a statistically significant difference (p < 0.00001). Moreover, on average, participants exposed to a combination of sham and actual ultrasound reported a net increase of 47.9 percentage points in the likelihood that they would report a visual effect by the end of the experiment. Our experiment demonstrated that a random combination of sham-only and actual diagnostic ultrasound applied to the visual cortex of participants increased the likelihood that they would observe visual effects, but not the type of effects, with that likelihood increasing over the course of the experiment. From this we conclude that repeated exposures by diagnostic ultrasound made the visual cortex more responsive to stimulation of their visual cortex by the visual target. These observations, consistent with other’s observation of effects of diagnostic ultrasound stimulation of human motor cortex and amygdala, as well as the FDA approved nature of diagnostic ultrasound, may lead to increased study of diagnostic ultrasound applied to human brain.

As a result of the COVID-19 pandemic people have endured potentially stressful challenges which have influenced behaviors such as eating. This pilot study examined the effectiveness of two brief interventions aimed to help individuals deal with food cravings and associated emotional experiences. Participants were 165 individuals residing in United Kingdom, Finland, Philippines, Spain, Italy, Brazil, North America, South Korea, and China. The study was implemented remotely, thus without any contact with researchers, and involved two groups. Group one participants were (...) requested to use daily diaries for seven consecutive days to assess the frequency of experience of their food cravings, frequency of giving in to cravings, and difficulty resisting cravings, as well as emotional states associated with their cravings. In addition to completing daily food diaries, participants in group two were asked to engage in mindful eating practice and forming implementation intentions. Participants assessed their perceived changes in eating, wellbeing, and health at the beginning and end of the intervention. Repeated measures MANOVAs indicated that participants experienced significantly less food cravings, as well as lower intensities of unpleasant states associated with cravings across time. In contrast to our hypothesis, the main effects of the group were not significant. Participants reported less eating and enhanced wellbeing at the end of the study. Our findings can be used to inform future remote interventions to manage food cravings and associated emotions and highlight the need for alternative solutions to increase participant engagement.

Objective: Body dissatisfaction is a major risk factor underlying vulnerability to eating disorders. Laboratory settings suggest that body dissatisfaction could be improved by using evaluative conditioning (EC). The present study evaluates the feasibility of using an EC app in everyday life and the effects of its use on body dissatisfaction. Method: We designed a game-like app inspired by the Therapeutic Evaluative Conditioning app. 60 participants were randomly assigned to two conditions. Participants in the EC condition had to pair photographs (...) of their own body with positive photographs, while participants in the neutral condition had to pair photographs of their own body with neutral photographs. We tested the effect of use of the app on body dissatisfaction, drive for thinness, self-esteem, mood and eating behaviors. Results: Analysis revealed that participants in all conditions presented a significant decrease in body dissatisfaction and drive for thinness. However, contrary to our hypothesis, these reductions were not greater in the EC condition than in the neutral condition. Conclusions: This is the first study to evaluate the effects of an app-based EC intervention targeting body image. Results appear to be promising and the app could easily be implemented in an ecological setting as it is a low effort, attractive and accessible intervention. However, these findings do not support the idea that evaluative conditioning is responsible for the effects. Results are discussed. (shrink)

A paradigm shift in the human chronotoxicity of xenobiotics would study two‐sided desynchronized phenomena of interfacial interactions between cyclic or periodic environmental insults and the endogenous response and recovery profile. These systems‐based networks are under the influence of well‐synchronized biological clocks and their metabolic regulators. This perspective argues in favor of addressing the concept of synchronization in studies involving critical life windows of susceptibility, or circadian rhythms, or 24‐hour (periodic) diurnal rhythms and answering whether these disruptions in synchronization would affect (...) response and recovery or disease phenotypes associated with environmental insults, e.g., xenobiotics. Synchronization or synchrony is defined as the totality of elements that appear during the same time period within a system, including the network of interactions between the system's elements. Desynchronized interfaces during critical life windows or in time‐repeated exposure events would likely lead to initiating a cascade of adverse health effects associated with differentiated disease phenotypes.

The executive hypothesis of self-regulation places cognitive information processing at the center of self-regulatory success/failure. While the hypothesis is well supported by cross-sectional studies, no study has tested its primary prediction, that temporary lapses in executive control underlie moments of self-regulatory failure. Here, we conducted a naturalistic experiment investigating whether short-term variation in executive control is associated with momentary self-regulatory outcomes, indicated by negative affect reactivity to everyday stressors. We assessed working memory capacity (WMC) through ultra-brief, ambulatory assessments on (...) smart phones five times per day in a 7-day ecological momentary assessment (EMA) study involving college-aged adults. We found that participants exhibited more negative affect reactivity to stressor exposures during moments when they exhibited lower than usual WMC. Contrary to previous findings, we found no between-person association between WMC and average stress reactivity. We interpret these findings as reflecting the role of executive control in determining one’s effective capacity to self-regulate. (shrink)

This article presents a meta-analysis of the impact of minimal exposure to affective stimuli on the emergence of enduring conscious affective feelings. Theories often assume that such affective feelings are linked to automatic appraisals of events (i.e. in the absence of an evaluative processing goal). However, few studies have tested this hypothesis. Moreover, they have provided divergent results. We propose a meta-analysis of these studies to get a clearer picture on this issue. The meta-analysis includes 22 studies (37 effect sizes; (...) combined N = 2159) in which participants were repeatedly exposed to affective stimuli in the absence of an evaluative processing goal before their mood was measured. In this analysis, we focused on the type of stimulus presentation (i.e. visible vs. masked) as well as on the type of stimulus (i.e. faces, pictures, words). The results indicate that the effect of a stimulus is moderated by the visibility of the stimuli. Repeated exposure to visible stimuli leads to congruency effects (i.e. positive stimuli lead to positive feelings), whereas exposure to masked stimuli leads to contrast effects (i.e. positive stimuli lead to negative feelings). Moreover, these effects seem to be restricted to some types of stimuli, with no detectable effects of emotional faces. (shrink)

Previous research suggests that exposure to nature may reduce delay discounting and thereby facilitate healthier dietary intake. This pre-registered study examined the impact of online exposure to images of natural scenes on delay discounting and food preferences. It was predicted that exposure to images of natural scenes would be associated with: lower delay discounting; higher desirability for fruits and vegetables ; and delay discounting would mediate the effect of nature-image exposure on food desirability. Adult participants were recruited to an online (...) between-subjects experiment in which they viewed a timed sequence of six images either showing natural landscape scenes or urban scenes. They then completed measures of mood, delay discounting and rated their momentary desire to eat four fruits and vegetables, and four energy-dense foods. There was no statistically significant effect of experimental condition on delay discounting or food desirability. Bayes factors supported the null hypothesis for discounting, and energy-dense food desirability, but provided no strong evidence for either hypothesis for F&V desirability. These findings indicate that brief online exposure to images of nature does not affect momentary impulsivity or energy-dense food preference, whereas for preference for less-energy dense foods, the evidence was inconclusive.

A worldwidemental health crisis is expected, as millions worldwide fear death and disease while being forced into repeated isolation. Thus, there is a need for new proactive approaches to improve mental resilience and prevent mental health conditions. Since the 1990s, art has emerged as an alternative mental health therapy in the United States and Europe, becoming part of the social care agenda. This article focuses on how visual esthetic experiences can create similar patterns of neuronal activity as those observed (...) when the reward system is activated. The activation of the reward structures could have a stress buffering effect, given the interdependence observed between the reward and stress systems. Therefore, could visual esthetic experiences stimulate mental resilience? And if this were the case, could art-based interventions be offered for mental health in the context of COVID-19 and beyond?

When experienced in-person, engagement with art has been associated—in a growing body of evidence—with positive outcomes in wellbeing and mental health. This represents an exciting new field for psychology, curation, and health interventions, suggesting a widely-accessible, cost-effective, and non-pharmaceutical means of regulating factors such as mood or anxiety. However, can similar impacts be found with online presentations? If so, this would open up positive outcomes to an even-wider population—a trend accelerating due to the current COVID-19 pandemic. Despite its promise, this (...) question, and the underlying mechanisms of art interventions and impacts, has largely not been explored. Participants were asked to engage with one of two online exhibitions from Google Arts and Culture. With just 1–2 min exposure, both improved negative mood, state-anxiety, loneliness, and wellbeing. Stepdown analysis suggested the changes can be explained primarily via negative mood, while improvements in mood correlated with aesthetic appraisals and cognitive-emotional experience of the exhibition. However, no difference was found between exhibitions. We discuss the findings in terms of applications and targets for future research. (shrink)

It is currently assumed that exposure to an artificial blue-enriched light enhances human alertness and task performance, but recent research has suggested that behavioural effects are influenced by the basal state of arousal. Here we tested whether the effect of blue-enriched lighting on vigilance performance depends on participants’ arousal level. Twenty-four participants completed four sessions (blue-enriched vs. dim light x low vs. high arousal) at 10 pm on four consecutive days, following a repeated-measures design. Participants’ arousal was manipulated (...) parametrically through the execution of a cycling task at two intensities (low vs. moderate), and was checked by monitoring their heart rate. On each session, distal and proximal skin temperatures were recorded as a neuroergonomic index of vigilance, while participants performed a 20-min psychomotor vigilance task (PVT) under either blue-enriched light or dim light conditions. The Positive and Negative Affect Schedule (PANAS), Karolinska Sleepiness Scale (KSS) and Borg Rating of Perceived Exertion Scale (RPE) were used to measure subjective psychological state. The results showed that the exercise-induced manipulation of arousal produced robust alerting effects in most measures, while the lighting manipulation only attenuated subjective sleepiness and enhanced positive affect, but it did not influence behaviour or physiology. Acute exposure to a blue-enriched light was practically ineffective when the arousal level was over baseline. The present research favoured the use of acute physical exercise over acute exposure to blue-enriched lighting in order to boost humans’ alertness when necessary, as in work settings where maintaining optimal levels of attention is difficult (shift work, night-work, vigilance tasks) and necessary to prevent human error and accidents.

Since its emergence, the novel coronavirus disease of 2019 has had enormous physical, social, and psychological impacts worldwide. The aim of this article was to identify elements of our knowledge on asbestos exposure and malignant mesothelioma that can provide insight into the psychological impact of the COVID-19 pandemic and be used to develop adequate interventions. Although the etiology of Covid-19 and MM differs, their psychological impacts have common characteristics: in both diseases, there is a feeling of being exposed through aerial (...) contagion to an “invisible killer” without boundaries that can strike even the strongest individuals. In both cases, affected persons can experience personality dysfunction, anxiety, depression, and posttraumatic symptoms; helplessness, hopelessness, and projection of destructive thoughts onto external forces often emerge, while defense mechanisms such as denial, splitting, repression, and reduced emotional expression are used by individuals to contain their overwhelming anxieties. We believe that in both diseases, an integrated multidimensional intervention offered by hospitals and other public health services is the most effective approach to alleviating patients’ and caregivers’ psychological distress. In particular, we emphasize that in the context of both MM and COVID-19, Brief Psychoanalytic Group therapy can help patients and caregivers attribute meaning to the significant changes in their lives related to the experience of the disease and identify adaptive strategies and more realistic relational modalities to deal with what has happened to them. We also highlight the importance of developing a surveillance system that includes individual anamnestic evaluation of occupational risk factors for COVID-19 disease. (shrink)

It has been argued that some recent experimental findings about the mere exposure effect can be used to argue for aesthetic antirealism: the view that there is no fact of the matter about aesthetic value. The aim of this paper is to assess this argument and point out that this strategy, as it stands, does not work. But we may still be able to use experimental findings about the mere exposure effect in order to engage with the aesthetic realism/antirealism debate. (...) However, this argument would need to proceed very differently and would only support a much more modest version of aesthetic antirealism. (shrink)

Gaze cueing effect (GCE) refers to attention orienting towards the gazed-at location, characterised by faster responses to gazed-at than non-gazed-at stimuli. A previous study investigated the effects of affective priming on GCE and reported that threatening primes enhanced GCE. However, it remains unknown whether the threat or heightened arousal potentiated GCE. We investigated how highly arousing threatening and positive primes, compared to low arousing neutral primes modulate GCE. After a brief exposure to an affective prime (pictures of threat (...) or erotica) or a neutral prime, participants detected an asterisk validly or invalidly cued by the gaze direction of a neutral face. The results showed that the threatening primes diminished the magnitude of GCE. The highly arousing positive primes did not have an effect on GCE. Further analyses showed that, as compared to neutral priming, the reaction times after threatening primes were shortened on invalid trials. This finding was interpreted to suggest that the threatening primes enhanced goal-directed target detection and attenuated attention orienting by irrelevant gaze cues via improving executive control. In sum, the present findings indicate that threat priming modulates GCE, not because of heightened arousal but because of the threat. (shrink)

The subjective impression that statements are true increases when statements are presented repeatedly. There are two sources for this truth effect: An increase in validity based on recollection and increase in processing fluency due to repeated exposure . Using multinomial processing trees , we present a comprehensive model of the truth effect. Furthermore, we show that whilst the increase in processing fluency is indeed automatic, the interpretation and use of that experience is not. Experiment 1 demonstrates the standard use (...) of the fluency experience and Experiment 2 demonstrates that people can change the interpretation of the experience according to its ecological validity. By implication, the truth effect represents the adaptive usage of feedback received from internal processes. (shrink)

In three experiments, picture quality between test items was manipulated to examine whether subjects’ expectations about the fluency normally associated with these different stimuli might influence the effects of fluency on preference or familiarity-based recognition responses. The results showed that fluency due to pre-exposure influenced responses less when objects were presented with high picture quality, suggesting that attributions of fluency to preference and familiarity are adjusted according to expectations about the different test pictures. However, this expectations influence depended on (...) subjects’ awareness of these different quality levels. Indeed, imperceptible differences seemed not to induce expectations about the test item fluency. In this context, fluency due to both picture quality and pre-exposure influenced direct responses. Conversely, obvious, and noticed, differences in test picture quality did no affect responses, suggesting that expectations moderated attributions of fluency only when fluency normally associated with these different stimuli was perceptible but difficult to assess.

This paper reports on the results from two studies that were conducted eight years apart with different respondents. The studies examined the role of the Mere Exposure Effect on ethical tolerance or acceptability of particular business decisions. The results from Study 1 show there is a significant difference in ethical judgment for 12 out of 16 vignettes between those who have been exposed to such situations compared to those who have not been exposed to them. In those 12 situations, those (...) who have been exposed to such situations adopted a more tolerant stance toward the ethically questionable behavior. The results from Study 2 show there is a significant difference in ethical judgment for 9 out of 16 vignettes between those who have been exposed to such situations compared to those who have not been exposed to them. Again, in those nine situations, those who have been exposed to such situations adopted a more tolerant stance toward the ethically questionable behavior. Interestingly, the 9 situations in Study 2 were 9 of the 12 situations found to be significant in Study 1, and in the same direction, suggesting that we have found consistency in our findings and support for the Mere Exposure Effect. Implications are provided for both higher education and practitioners. (shrink)

Computer users are often the last line of defense in computer security. However, with repeated exposures to system messages and computer security warnings, neural and behavioral responses show evidence of habituation. Habituation has been demonstrated at a neural level as repetition suppression where responses are attenuated with subsequent repetitions. In the brain, repetition suppression to visual stimuli has been demonstrated in multiple cortical areas, including the occipital lobe and medial temporal lobe. Prior research into the repetition suppression effect (...) has generally focused on a single repetition and has not examined the pattern of signal suppression with repeated exposures. We used complex, everyday stimuli, in the form of images of computer programs or security warning messages, to examine the repetition suppression effect across repeated exposures. The use of computer warnings as stimuli also allowed us to examine the activation of learned fearful stimuli. We observed widespread linear decreases in activation with repeated exposures, suggesting that repetition suppression continues after the first repetition. Further, we found greater activation for warning messages compared to neutral images in the anterior insula, pre-supplemental motor area, and inferior frontal gyrus, suggesting differential processing of security warning messages. However, the repetition suppression effect was similar in these regions for both warning messages and neutral images. Additionally, we observed an increase of activation in the default mode network with repeated exposures, suggestive of increased mind wandering with continuing habituation. (shrink)

ObjectivesConstant Installation of Present Orientation and Safety is a Eye Movements Desensitization and Reprocessing -derived technique, which is often used to prepare for the treatment of post-traumatic stress disorder. It differs from the latter by involving cyclically recurring exercises in reorientation to the present, interspersed between brief periods of exposure to the traumatic material.While EMDR is well established as a therapeutic method, the efficacy and mechanisms of action of CIPOS have not been investigated so far. In this pilot study, (...) an experimental setting was used to record the subjective and physiological effects of the CIPOS intervention compared to a control condition with pure mental exposition.MethodsThe study was performed on 30 healthy volunteers aged from 20 to 30 years. Distress was induced using audio files of subjectively stressful situations. Subjective distress was measured via the Subjective Units of Distress Scale, while physiological indicators were used as measures for objective stress. For each condition, pre- and post-intervention comparisons were calculated.ResultsIn both groups, startle reflex potentiation and mean skin conductance level significantly decreased. In the group with CIPOS intervention, but not in the control group, a significant decrease in the SUD value was found.Conclusion and significanceThe results show that the CIPOS technique is as effective as pure mental exposition in reducing physiological stress. In addition, a superiority in reducing subjective distress was found compared to pure mental exposition. Possible explanations of these effects are discussed. (shrink)

People tend to grossly overestimate the size of their mirror-reflected face. Although this overestimation bias is robust, not much is known about its relationships to self-face perception. In two experiments, we investigated the overestimation bias as a function of the presentation of the own face , the identity of the seen face, and prior exposure to a real mirror. For this we developed a computerized task requiring size estimations of displayed faces. We replicated the observation that people overestimate the size (...) of their mirror-reflected face and showed that the overestimation can be reduced following a brief mirror exposure. We also found that left–right reversal modulates the overestimation bias, depending on the perceived face’s identity. These data underline the enhanced familiarity of left–right reversed self-faces and the importance of size perception for understanding mirror reflection processing. (shrink)

We examined whether variations in contextual diversity, spacing, and retrieval practice influenced how well adults learned new words from reading experience. Eye movements were recorded as adults read novel words embedded in sentences. In the learning phase, unfamiliar words were presented either in the same sentence repeated four times (same context) or in four different sentences (diverse context). Spacing was manipulated by presenting the sentences under distributed or non‐distributed practice. After learning, half of the participants were asked to retrieve (...) the new words, and half had an extra exposure to the new words. Although words experienced in diverse contexts were acquired more slowly during learning, they enjoyed a greater benefit of learning at immediate posttest. Distributed practice also slowed learning, but no benefit was observed at posttest. Although participants who had an extra exposure showed the greatest learning benefit overall, learning also benefited from retrieval opportunity, when words were experienced in diverse contexts. These findings demonstrate that variation in the content and structure of the learning environment impacts on word learning via reading. (shrink)
