Objective: Body checking (BC) and avoidance (BA) form the behavioral component of body image disturbance. High levels of BC/BA have often been documented to hold a positive and potentially reinforcing relationship with eating pathology. While some researchers hypothesize, that patients engage in BC/BA to prevent or reduce levels of anxiety, little is known about the mediating factors. Considering the great comorbidity between eating disorders and in particular social anxieties, the present study investigated whether socially relevant types of anxiety mediate the (...) relationship between eating pathology and BC/BA. Method: 83 participants reporting an eating disorder and 323 healthy participants (14-25 years) took part in an online survey. Eating pathology was measured with the Eating Disorder Examination Questionnaire and Body Checking and Avoidance Questionnaire. Trait and social anxiety were assessed by means of the State Trait Anxiety Inventory (STAI-T), the Fear of Negative Evaluation (FNE) and the Social Appearance and Anxiety Scale (SAAS). Separate mediation analyses were carried out with eating pathology as independent variable, BC/BA as dependent variable and STAI, FNE and SAAS as mediating variables. Results: Anxieties correlated highly positive with eating pathology in both groups. SAAS mediated the relationship between ED pathology and BC/BA in participants with ED and mediated the relationship between ED pathology and BA in healthy participants. FNE mediated the relationship between eating pathology and BA for participants with eating pathology. Discussion: SAAS mediated the relationship between eating pathology and BC/BA. Being afraid of bodily evaluations may represent a particular relevant fear that triggers safety behaviors. (shrink)
ABSTRACTWhen processing information about human faces, we have to integrate different sources of information like skin colour and emotional expression. In 3 experiments, we investigated how these features are processed in a top-down manner when task instructions determine the relevance of features, and in a bottom-up manner when the stimulus features themselves determine process priority. In Experiment 1, participants learned to respond with approach-avoidance movements to faces that presented both emotion and colour features. For each participant, only one of these (...) two features was task-relevant while the other one could be ignored. In contrast to our predictions, we found better learning of task-irrelevant colour when emotion was task-relevant than vice versa. Experiment 2 showed that the learning of task-irrelevant emotional information was improved in general when participants’ awareness was increased by adding NoGo-trials. Experiment 3 replicated these results... (shrink)
ABSTRACTFacial expressions play a central role in diverse areas of psychology. However, facial stimuli are often only validated by adults, and there are no face databases validated by school-aged c...
ABSTRACTWe used an immersive virtual environment to examine avoidance learning in spider-fearful participants. In 3 experiments, participants were asked to repeatedly lift one of 3 virtual boxes, under which either a toy car or a spider appeared and then approached the participant. Participants were not told that the probability of encountering a spider differed across boxes. When the difference was large, spider-fearfuls learned to avoid spiders by lifting the few-spiders-box more often and the many-spiders-box less often than non-fearful controls did. (...) However, they hardly managed to do so when the probability differences were small, and they did not escape from threat more quickly. In contrast to the observed performance differences, spider-fearfuls and non-fearfuls showed equal competence, that is comparable post-experimental knowledge about the probability to encounter spiders under the 3 boxes. The limitations and implications of the present study are discussed. (shrink)
