ABSTRACT The current study examined the role of Behavioral Approach System (BAS) and Behavioral Inhibition System (BIS) sensitivity in predicting symptoms along the externalizing dimension of psychopathology. A sample of 273 undergraduates completed measures of BAS, BIS, and externalizing disorder symptomatology. Regression analyses indicated that high BAS predicted drug abuse, alcohol abuse, primary and secondary psychopathy, and hyperactive-impulsive AD/HD symptoms. Whereas low BIS predicted drug use and hyperactive-impulsive symptoms only, high BIS predicted secondary psychopathy and inattentive AD/HD symptoms. These results replicate previous findings and suggest that high BAS is closely associated with the externalizing dimension. In contrast, the results from the current study call into question the role of low BIS in externalizing disorders and provide only limited support for the joint-subsystems hypothesis in this context.

    ABSTRACT: Attention-Deficit/Hyperactivity Disorder (ADHD) and Tourette Syndrome (TS) present as distinct conditions clinically; however, they show comorbidity and inhibitory control deficits have been proposed to underlie both. The role of reinforcement sensitivity in ADHD has been studied previously, but no study has addressed this in relation to TS-like behaviors in the general population. The present study examined these associations within the remit of the revised Reinforcement Sensitivity Theory (rRST). One hundred and thirty-eight participants completed psychometric measures of the rRST, and self-report checklists for ADHD- and TS-like behaviors. The results show that whilst ADHD-inattention was only linked to increased anxiety (BIS), ADHD-hyperactivity/impulsivity was linked to increased impulsivity (BAS-fun seeking), anxiety (BIS) and punishment sensitivity (FFFS), and to reduced reward sensitivity (BAS-reward responsiveness), independently of ‘comorbid’ TS-like behaviors. TS-related phonic tics were associated with increased BIS and FFFS, and TS-related obsessive-compulsive behaviors (OCBs) with increased goal-orientation (BAS-drive) and reduced impulsivity (BAS-fun seeking). However, these associations were driven by ADHD-like behaviors or OCB co-occurrence, respectively, suggesting little role of the rRST in pure TS-like behaviors. The results are discussed in light of mixed findings in the literature and the importance of distinguishing between multiple processing models of the rRST in distinct disorder phenotypes.

    ABSTRACT: Despite previous studies of psychopathy and the motivational systems of the Reinforcement Sensitivity Theory (RST) of personality, few have examined psychopathy in light of the revised RST model. In a large sample (N = 779) of young adults, we expand on Hughes, Moore, Morris, and Corr’s (2012) preliminary findings relating primary/secondary psychopathy to revised RST’s three systems: Flight-Flight-Freeze System (FFFS), Behavioral Inhibition System (BIS), and Behavioral Approach System (BAS). Converging results between Hughes et al. and the current study emphasize three major findings: (1) primary psychopathy is negatively related to the BIS as well as the FFFS; (2) primary psychopathy is positively related to goal-driven behavior of the BAS; and, (3) secondary psychopathy is positively related to impulsivity reflected in the BAS. The FFFS was incrementally predictive of primary but not secondary psychopathy. No evidence for a BAS × BIS interaction in psychopathy was found. Results are discussed in terms of future research directions.

    ABSTRACT: The study examined the relation between reward and punishment sensitivity and antisocial behavior (ASB) in male adolescents. We compared Behavioral Inhibition/Behavioral Activation System (BIS/BAS) Scale scores in adolescent male offenders (n = 85) and non-offenders (n = 50), and explored the relation between BIS/BAS and measures associated with ASB (psychopathy, conduct problems and alcohol use) within the whole group of adolescents, and offending frequency in the offenders. Between group analyses indicated heightened BAS (reward sensitivity; specifically the drive to seek rewards) and lowered BIS (punishment sensitivity) in the offenders compared to the non-offenders. Regression analyses indicated that traits associated with reward seeking (BAS Drive and/or Fun Seeking) positively predicted psychopathic traits, conduct problems and alcohol use. In contrast, response to reward (BAS Reward Responsiveness) was negatively associated with psychopathy and conduct problems. Reduced punishment sensitivity (BIS) was associated with psychopathy only. The findings suggest that BAS reward traits are useful in understanding ASB and emphasize the importance of examining dimensions of reward processing in relation to different aspects of ASB in adolescents.
