Psoriasis is a chronic debilitating disease which is frequently associated with strong psychological distress and psychological conditions (e.g., depression, anxiety). Although some studies have indicated a relationship between this condition and difficulties in emotion regulation (as they are self-reported by the patients), behavioral and physiological evidence about this link are scarce.
Members of highly social species decode, interpret, and react to the emotion of a conspecific depending on whether the other belongs to the same (ingroup) or different (outgroup) social group. While studies indicate that consciously perceived emotional stimuli drive social categorization, information about how implicit emotional stimuli and specific physiological signatures affect social categorization is lacking. We addressed this issue by exploring whether subliminal and supraliminal affective priming can influence the categorization of neutral faces as ingroup versus outgroup.
