title: Perceptions of social dominance through facial emotion expressions in euthymic patients with bipolar I disorder.
abstract: The ability to accurately perceive dominance in the social hierarchy is important for successful social interactions. However, little is known about dominance perception of emotional stimuli in bipolar disorder. The aim of this study was to investigate the perception of social dominance in patients with bipolar I disorder in response to six facial emotional expressions. Participants included 35 euthymic patients and 45 healthy controls. Bipolar patients showed a lower perception of social dominance based on anger, disgust, fear, and neutral facial emotional expressions compared to healthy controls. A negative correlation was observed between motivation to pursue goals or residual manic symptoms and perceived dominance of negative facial emotions such as anger, disgust, and fear in bipolar patients. These results suggest that bipolar patients have an altered perception of social dominance that might result in poor interpersonal functioning. Training of appropriate dominance perception using various emotional stimuli may be helpful in improving social relationships for individuals with bipolar disorder.
