Behavioral inhibition system (BIS) strength and trait dominance are associated with affective response and perspective taking when viewing dyadic interactions.
The neurophysiology underlying the Behavioral Activation and Behavioral Inhibition Systems (BAS and BIS) and the impact of the strength of these systems on affective processing have received increased attention over the last 25 years. Specifically, left-frontal brain regions have been implicated in BAS strength as well as the experience of positive-approach affect (such as happiness). Conversely, BIS strength and negative-avoidance affect (such as fear) appear to be modulated by right-frontal brain regions. Taken together, it is not surprising that BAS and BIS strength have been associated with positive and negative affective biases, respectively, to emotional stimuli that do not involve extensive human interaction. The present investigation was designed to extend these findings by assessing the relationship between BAS and BIS strength on the perception of emotional interactions. Participants (n = 67) were shown four 2-min film clips that depict an individual exerting dominance over one or more other individuals. Each participant rated the clips with regard to valence, arousal, and dominance parameters, and then indicated the person(s) in the movie with whom they identified (i.e., the dominant individual or submissive individual[s]). Consistent with a priori hypotheses, persons identifying with the submissive character scored significantly higher on BIS sensitivity. BAS strength and BIS/BAS ratio, conversely, were not associated with character identification. Also as predicted, identification with the dominant movie character was associated with increased positive affect and feelings of dominance. Interestingly, although not hypothesized, trait dominance was also associated with character identification by virtue of being positively associated with BAS and PA and negatively associated with BIS and NA.
