The role of cognitive appraisal in media-induced presence and emotions

In the present study, we applied Valins’ (1966) bogus bodily feedback paradigm to investigate the roles of cognitive appraisal (tele)presence, and emotion in the context of media usage. Participants (N=30) viewed short sequences of a TV show, whereby false heart rate feedback was provided. In line with Valins’ paradigm, the manipulation we used in this study included two levels: high vs. low false heart rate feedback. We assessed presence, enjoyment, and the real heart rate. Participants reported stronger experiences of presence and enjoyed the clips more when they wrongly believed that they had been aroused. Since bogus feedback increases the sensation of presence, the results indicate that presence—like emotions—can be influenced by cognitive appraisals. It is likely that the false heart rate feedback was attributed to the stimulus, which in turn enhanced the sensation of presence.     

Influence of mental imagery on spatial presence and enjoyment assessed in different types of media

Previous research studies on spatial presence point out that the users' imagery abilities are of importance. However, this influence has not yet been tested for different media. This is surprising because theoretical considerations suggest that mental imagery comes into play when a mediated environment lacks vividness. The aim of this study was to clarify the influence mental imagery abilities can have on the sensation of presence and enjoyment in different mediated environments. We presented the participants (n?=?60) a narrative text, a movie sequence, and a computer game. Across all media, no effect of mental imagery abilities on presence and enjoyment was found, but imagery abilities marginally interacted with the mediated environment. Individuals with high imagery abilities experienced more presence and enjoyment in the text condition. The results were different for the film condition: here, individuals with poor imagery abilities reported marginally higher enjoyment ratings, whereas the presence ratings did not differ between the two groups. Imagery abilities had no influence on presence and enjoyment within the computer game condition. The results suggest that good imagery abilities contribute to the sensations of presence and enjoyment when reading a narrative text. The results for this study have an applied impact for media use because their effectiveness can depend on the individual mental imagery abilities.     

Unconscious task set priming with phonological and semantic tasks

Whether unconscious stimuli can modulate the preparation of a cognitive task is still controversial. Using a backward masking paradigm, we investigated whether the modulation could be observed even if the prime was made unconscious in 100% of the trials. In two behavioral experiments, subjects were instructed to initiate a phonological or semantic task on an upcoming word, following an explicit instruction and an unconscious prime. When the SOA between prime and instruction was sufficiently long (84 ms), primes congruent with the task set instruction led to speedier responses than incongruent primes. In the other condition (36 ms), no task set priming was observed. Repetition priming had the opposite tendency, suggesting the observed task set facilitation cannot be ascribed solely to perceptual repetition priming. Our results therefore confirm that unconscious information can modulate cognitive control for currently active task sets, providing sufficient time is available before the conscious decision.     

The influence of neuroticism on spatial presence and enjoyment in films

The purpose of the present study was to clarify the influence of neuroticism on the sensation of spatial presence and enjoyment in films. We presented participants (N = 64) a fearful, sad, and funny movie sequence. Across all media, individuals scoring high on neuroticism experienced more presence than those scoring low. In contrast, no main effect was found on enjoyment. In terms of enjoyment, however, neuroticism interacted with the valence of the sequences: in the two conditions with negative valence (fearful and sad sequence), participants scoring high on neuroticism reported less enjoyment than those scoring low on neuroticism. Opposite results were observed in the funny sequence: participants scoring high on neuroticism enjoyed the funny sequence more than those scoring low on neuroticism. Thus, neuroticism increased presence within all conditions, whereas individuals scoring high on neuroticism only experienced increased enjoyment in positive media contents.

Systematic approach to the diagnosis of lysosomal storage disorders

Disorders that arise as a result of lysosomal dysfunction represent some of the most challenging diagnostic problems in medicine. Not only are these disorders infrequently seen, but they may also present with signs and symptoms that mimic perinatal injury, food intolerance, or the sequellae of neonatal infection. Misidentification can lead to significant delay in diagnosis. Ironically, as the prevailing economic climate places increasing time constraints on practicing physicians, medical research is providing treatment strategies and management techniques that are most effective if applied early in the course of the disease. Most lysosomal storage disorders can now be definitively diagnosed once the signs are recognized. In many cases the benefits of early diagnosis, enlightened management, and appropriate referral are considerable. The aim of this paper is to demystify this elusive class of diseases, to promote clinical vigilance in their detection, and to provide a systematic approach to diagnosis when clinical suspicion is aroused.

The Fantasy Questionnaire: A Measure to Assess Creative and Imaginative Fantasy

This article reports the construction and validation of a comprehensive self-report measure of fantasy. Unlike previous measures of fantasy, which focus on psychopathology, we conceive fantasy as a trait with positive connotation. Principal component analysis (N = 318) and confirmatory factor analyses (N = 345) were conducted using 2 sociodemographically diverse samples. The results provided support for a 2-factor conceptualization of the construct, with the dimensions imaginative fantasy and creative fantasy. Imaginative fantasy refers to vivid imagination and absorption in these images and daydreams. Creative fantasy refers to the activity of using fantasy to create new ideas. The trait measure showed good internal consistency, test–retest reliability, discriminant and convergent construct validity, as well as incremental validity. Moreover, in 3 behavioral studies, we put fantasy scores in relationship with behavioral data to provide further proof of validity. A comprehensive measure of fantasy can contribute to our understanding of individual differences in inner experiences, creative processes, and problem solving.     

How children with facial differences are perceived by non-affected children and adolescents: Perceiver effects on stereotypical attitudes

Children with a facial difference are presumed to be at risk of social stigmatization. The purposes of this study were twofold: (1) to assess the effect of facial differences on social perceptions by unaffected children and adolescents; and (2) to identify perceiver characteristics that predict stereotypical attitudes toward facial differences. Participants were 344 non-affected children and adolescents, ages 8–17 years. Participants rated digitally altered images of 12 children depicted either with or without a facial difference. Results show that participants attributed less favorable characteristics to children with a facial difference than to those without. Moreover, participants reported less willingness to interact with or befriend a child with a facial difference. Significant predictors of low discriminative attitudes were older participant age and previous contact with someone with a facial difference. Our data call attention to the need for public education programs targeted at reducing negative attitudes toward facial differences.
