Abstract
Individual differences in motivation and approach behavior exist, and underlie independent dimensions of personality. The Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS) refer to distinct neurophysiological systems that are proposed to govern two broad facets of personality: trait anxiety and impulsivity. These systems comprise Gray's Biopsychosocial Theory of Personality. The BIS is thought to govern aversive approach and avoidance, and responds to cues of punishment or nonreward, whereas the BAS governs appetitive approach, and responds to cues of reward. Extremes of BIS and BAS sensitivity are proposed to explain the development of various psychological disorders.
