Presentation abstract: The role of emotional processing in obesity has only recently become the focus of active research. Regarding the automatic emotional processing, research has shown that individuals with obesity (OB) present a tendency to inhibit attention from negative emotions. However, studies in this field are still scarce, focused on emotional awareness, and seldom consider the presence of disordered eating behaviors. The aim of this study is to explore the neural mechanisms associated with automatic emotional processing in obesity (through the analysis of event-related potentials – ERP) and analyze whether possible impairments are related with the presence of binge eating disorder (BED). We expect to screen 30 participants with obesity diagnosis and 30 with normal weight for the presence of BED, depression/ anxiety. Participants will also complete a dot probe task of emotional faces while EEG activity is recorded. Data collection is still underway, but it is expected OB to show an attentional avoidance of negative emotions reporting lower reaction times and less response precision than normal weight participants, independently of self-reported depression/ anxiety. Also ERP analysis should show a decreased N2pc towards negative emotions. Greater impairments are expected to be observed in individuals with BED. Emotional avoidance is considered a strategy to escape from personal problems and negative emotional states which has been related to OB and moreover to binge eating symptoms. Therefore, this negativity bias (if demonstrated) may occur due to the difficulties imposed by the disease and presents some clues on how OB individuals, especially with BED, cope with emotions.
