The Mass Media

The prevalence of autism is growing, the problems of stigmatization and discrimination of people with autism spectrum disorders in society are exacerbating. The mass media play an important role in enlightening and reducing stigmatizing effects, in connection with which the goal was formulated to study the construction of images of a person with ASD in the mass media by the method of qualitative and discourse analysis of video clips from the federal channel. According to the results of the study, it can be argued that the range of characteristics used to describe people with autism in media discourse is diverse, but in retrospect, dominant interpretation models can be identified. At an early stage, the prevailing image of a person with ASD was deprived of the quality’s characteristic of normotypical people who do not want to leave their world. People diagnosed with autism were referred to as the intolerant category of "autistic". Since 2013, there has been a discursive turn, within which the category “autist” is replaced by tolerant speech patterns, adults with autism get into the lens of the media, the topic of uncommunicability as a property of a person with autism is replaced by the intention of the lack of opportunities to communicate, one of the reasons for which is social exclusion. In television stories of recent years, the mass media are actively constructing the image of a person with autism spectrum disorder through his inner world, through the advantages that a person with ASD can have due to his characteristics. However, it cannot be said that there has been a complete change of the image: the old cliches, as a rule, manifest themselves at a more latent level of grammatical constructions and semiotic meanings.

We investigated the differences in the emotional experiences of people who smoke and have damaged interoceptive awareness. Interoception is the sensation of the physiological condition of the body, and it has 2 biases: neglect and amplification of bodily feedback. We recruited 72 participants and divided them into 4 groups according to smoking status and interoceptive bias based on their scores on the Multidimensional Assessment of Interoceptive Awareness. All groups assessed their physiological and subjective arousal before and after watching video clips (positive–low arousal, positive–high arousal, negative–low arousal, negative–high arousal, neutral). The results indicated that people with amplification (vs. neglect) bias who smoked showed stronger subjective arousal to neutral stimuli. In contrast, people with amplification (vs. neglect) bias who did not smoke showed stronger subjective arousal to positive stimuli. These findings suggest that people who smoke and have an amplification bias could be more likely to misinterpret neutral emotional stimuli, leading to an increased craving for smoking.

Valence And Arousal

Most studies of emotional responses have used unimodal stimuli (e.g., pictures or sounds) or congruent bimodal stimuli (e.g., video clips with sound), but little is known about the emotional response to incongruent bimodal stimuli. The aim of the present study was to evaluate the effect of congruence between auditory and visual bimodal stimuli on heart rate and self-reported measures of emotional dimension, valence and arousal. Subjects listened to pleasant, neutral, and unpleasant sounds, accompanied by videos with and without content congruence, and heart rate was recorded. Dimensions of valence and arousal of each bimodal stimulus were then self-reported. The results showed that heart rate depends of the valence of the sounds but not of the congruence of the bimodal stimuli. The valence and arousal scores changed depending on the congruence of the bimodal stimuli. These results suggest that the congruence of bimodal stimuli affects the subjective perception of emotion.

Facial Trustworthiness

Researchers have found that compared with other existing conditions (e.g., pleasantness), information relevant to survival produced a higher rate of retrieval; this effect is known as the survival processing advantage (SPA). Previous experiments have examined that the advantage of memory can be extended to some different types of visual pictorial material, such as pictures and short video clips, but there were some arguments for whether face stimulus could be seen as a boundary condition of SPA. The current work explores whether there is a mnemonic advantage to different trustworthiness of face for human adaptation. In two experiments, we manipulated the facial trustworthiness (untrustworthy, neutral, and trustworthy), which is believed to provide information regarding survival decisions. Participants were asked to predict their avoidance or approach response tendency, when encountering strangers (represented by three classified faces of trustworthiness) in a survival scenario and the control scenario. The final surprise memory tests revealed that it was better to recognize both the trustworthy faces and untrustworthy faces, when the task was related to survival. Experiment 1 demonstrated the existence of a SPA in the bipolarity of facial untrustworthiness and trustworthiness. In Experiment 2, we replicated the SPA of trustworthy and untrustworthy face recognitions using a matched design, where we found this kind of memory benefits only in recognition tasks but not in source memory tasks. These results extend the generality of SPAs to face domain.

Abstract Background and study aims The Paris classification of superficial colonic lesions has been widely adopted, but a simplified description that subgroups the shape into pedunculated, sessile/flat and depressed lesions has been proposed recently. The aim of this study was to evaluate the accuracy and inter-rater agreement among 13 Western endoscopists for the two classification systems. Methods Seventy video clips of superficial colonic lesions were classified according to the two classifications, and their size estimated. The interobserver agreement for each classification was assessed using both Cohen k and AC1 statistics. Accuracy was taken as the concordance between the standard morphology definition and that made by participants. Sensitivity analyses investigated agreement between trainees (T) and staff members (SM), simple or mixed lesions, distinct lesion phenotypes, and for laterally spreading tumors (LSTs). Results Overall, the interobserver agreement for the Paris classification was substantial (κ = 0.61; AC1 = 0.66), with 79.3 % accuracy. Between SM and T, the values were superimposable. For size estimation, the agreement was 0.48 by the κ-value, and 0.50 by AC1. For single or mixed lesions, κ-values were 0.60 and 0.43, respectively; corresponding AC1 values were 0.68 and 0.57. Evaluating the several different polyp subtypes separately, agreement differed significantly when analyzed by the k-statistics (0.08–0.12) or the AC1 statistics (0.59–0.71). Analyses of LSTs provided a κ-value of 0.50 and an AC1 score of 0.62, with 77.6 % accuracy. The simplified classification outperformed the Paris classification: κ = 0.68, AC1 = 0.82, accuracy = 91.6 %. Conclusions Agreement is often measured with Cohen’s κ, but we documented higher levels of agreement when analyzed with the AC1 statistic. The level of agreement was substantial for the Paris classification, and almost perfect for the simplified system.
