Psychopathic individuals are generally unresponsive to motivational and emotional cues that facilitate behavioral regulation. A putative mechanism for this deficiency is Gray’s (1981) behavioral inhibition system (BIS). To evaluate the association between psychopathy and BIS functioning, we administered a laboratory-based assessment of BIS functioning to a group of psychopathic offenders assess...

background: diabetes mellitus is a common metabolic disorder worldwide. it imposes excessive psychological stress on patients which negatively affect the course of the disease. the brain-behavioral systems have a role in dealing with stressful events such as chronic disorders. objective: comparison the brain-behavioral systems and psychological distress in diabetic patients and non-diabetics. m...

Gray's Reinforcement Sensitivity Theory postulates that the behavioral inhibition system (BIS) is responsible for regulating anxiety and fear in response to external stimuli, while activation (BAS) processing positive cues such as rewards. Dickman's model distinguishes dysfunctional impulsivity (DI), characterized by non-reflective decision-making, from functional (FI), which reflects propensit...

Introduction: Studies related to investigating reasons of mental disorders emphasize on role of environmental factors in creation of the disorders. For this reason, in this paper, a research was conducted to investigate the relationship between BIS/BAS systems and emotional regulation difficulties with alexithymia. Methods: 200 undergraduate students of University of Tabriz in majors includi...

In this study, we examined the viability of measuring personality using computerized lexical analysis of natural speech. Two well-validated models of personality were measured, one involving trait positive affectivity (PA) and negative affectivity (NA) dimensions and the other involving a separate behavioral inhibition motivational system (BIS) and a behavioral activation motivational system (B...

In two studies, we explore the neurobiological basis of the General Factor of Personality (GFP) by correlating it with measures of the Behavioral Inhibition System–Behavioral Activation System (BIS–BAS), generalized expectancies of reward and punishment, self-esteem, and positive and negative affect. The GFP was measured by aggregating across the scales of the Big Five Inventory (reverse keying...

Reinforcement Sensitivity Theory predicts that those with a strong behavioral inhibition system (BIS) likely experience considerable anxiety and uncertainty during the transition out of university. Accordingly, they may continue to drink heavily to cope during this time (a period associated with normative reductions in heavy drinking), but only if they also have a strong behavioral approach sys...

introduction: this paper investigates the relationships between extraversion, neuroticism and psychoticism dimensions with brain / behavioral systems. methods: randomly selected 128 female university students in tehran completed gray-wilson personality questionnaire and eysenck personality questionnaire-reversion, using pearson correlation coefficiency and regression analysis, result: the resul...

Joint effects of daily events and dispositional sensitivities to cues of reward and punishment on daily positive affect (PA) and negative affect (NA) were examined in 3 diary studies. Study 1 showed that positive events were strongly related to PA but not NA, whereas negative events were strongly related to NA but not PA. Studies 2 and 3 examined how the dispositional sensitivities of independe...
