Reinforcement sensitivity theory proposes three brain-behavioral systems that underlie individual differences in sensitivity to reward, punishment and motivation. Though not originally framed as a theory of personality, it has since been used to study and predict anxiety, impulsivity and extraversion, and it developed out of Jeffrey Gray's biopsychological theory of personality, incorporating findings from across psychology and neuroscience before undergoing a major revision in 2000 that distinguished fear from anxiety and proposed functionally related subsystems for each. Built on Gray's earlier behavioral inhibition system and behavioral activation system, the theory continues to inform the study of anxiety disorders in clinical settings and is used today to study and predict work performance and predispositions toward alcohol and drug abuse, even as disagreement continues over whether its subsystems should be treated as related or independent.
