Behavioral and personality characteristics are factors that may jointly regulate body weight. This study explored the relationship between body mass index (BMI) and self-reported behavioral and personality measures. These measures included eating behavior (based on the Three-Factor Eating Questionnaire; Stunkard and Messick, 1985), sensitivity to reward and punishment (based on the Behavioral I...

Gray's (1970) reinforcement sensitivity theory (RST) was recently updated (Gray & McNaughton, 2000), but the changes have not received extensive empirical validation. The study tests three novel predictions of the revised RST. First, the behavioral activation system (BAS) is expected to be sensitive to both conditioned and unconditioned incentives. Second, the behavioral inhibition system (BIS)...

Behavioral motivation is regulated through the behavioral inhibition system (BIS) and the behavioral approach system (BAS), which underlie responses to emotional stimuli and are thought to influence emotion dysregulation. Research shows that mindfulness may increase the efficacy of emotion regulation among those with psychological symptoms, but the relationships between behavioral motivation an...

The behavioral inhibition system (BIS) and behavioral approach system (BAS) are thought to influence sensitivity to reinforcement and punishment, making them useful for predicting mood-related drinking outcomes. This study provided the first examination of BIS and BAS as moderators of longitudinal within-person associations between mood and alcohol-related consequences in college student drinke...

Gray’s two-factor model represents motivation in terms of a behavioral inhibition (BIS) and a behavioral activation system (BAS). Although this model has theoretical links to psychopathy, few studies have examined this relationship. In a sample of 326 noninstitutionalized young adults, we examined the relationship of the BIS/BAS dimensions to multiple indices of primary and secondary psychopath...

background: gray`s reinforcement sensitivity theory (rst) presupposes individual differences in the sensitivity of basic brain systems that respond to punishing and reinforcing stimuli. these differences are thought to underlie the personality dimensions of anxiety and impulsivity, and to have relevance for psychopathology. the present study aims at studying the relationship between behavioural...

a r t i c l e i n f o Keywords: Trait anxiety State anxiety Intertemporal decision making The behavioral inhibition system Family socioeconomic status in childhood Based on Gray's theory, which links the behavioral inhibition motivation system (BIS) to the personality trait of " anxiety " , the present study examined whether anxiety (trait vs. state), BIS sensitivity, and family socioeconomic s...

This study examined the relationship between reinforcement sensitivity theory (RST), life stress, and internalizing symptoms. Generally, low sensitivity of the behavioral approach system (BAS) predicts depression whereas high sensitivity of the behavioral inhibition system (BIS) predicts anxiety and depression. However, few studies have examined how RST variables interact with life stress to pr...
