Comprehensive models, targeting the development of eating disorders (EDs) in males, often employ a sociocultural perspective and empathize the importance of body dissatisfaction (BD). To further illuminate psychological factors contributing to the development of ED pathology, we propose a mediator model of disturbed eating and compensatory behavior (DECB) for men. This model suggests that emotion dysregulation and the susceptibility to body-related cognitive distortions (thought-shape fusion, TSF) mediate the relationship between BD and DECB. Based on data from a cross-sectional online-survey we tested our model in a non-clinical community sample of young men (N=123, 18-37 years). We found a significant positive association between BD and DECB, accounting for participant's body mass index (BMI), age and depressive symptoms. While TSF partially mediated the relationship between BD and DECB, we did not detect a corresponding effect for emotion dysregulation. Based on our findings, we concluded that TSF, which describes specific distorted cognitions with respect to one's own body triggered by fattening/ forbidden food, contributes to the pathological eating- and body-related behavior in men who are dissatisfied with their body. We suggest that TSF should be included in etiological models as a relevant aspect of cognitive information processing with emotional and behavioral consequences.

The visual environment of humans contains abundant ambiguity and fragmentary information. Therefore, an early step of vision must disambiguate the incessant stream of information. Humorous stimuli produce a situation that is strikingly analogous to this process: Funniness is associated with the incongruity contained in a joke, pun, or cartoon. Like in vision in general, appreciating a visual pun as funny necessitates disambiguation of incongruous information. Therefore, perceived funniness of visual puns was implemented to study visual perception in a sample of 36 schizophrenia patients and 56 healthy control participants. We found that both visual incongruity and Theory of Mind (ToM) content of the puns were associated with increased experienced funniness. This was significantly less so in participants with schizophrenia, consistent with the gestalt hypothesis of schizophrenia, which would predict compromised perceptual organization in patients. The association of incongruity with funniness was not mediated by known predictors of humor appreciation, such as affective state, depression, or extraversion. Patients with higher excitement symptoms and, at a trend level, reduced cognitive symptoms, reported lower funniness experiences. An open question remained whether patients showed this deficiency of visual incongruity detection independent of their ToM deficiency. Humorous stimuli may be viewed as a convenient method to study perceptual processes, but also fundamental questions of higher-level cognition.
