Reinforcement sensitivity theory and symptoms of personality disorder: Specificity of the BIS in Cluster C and BAS in Cluster B

Gray’s reinforcement sensitivity theory, consisting of the behavioral inhibition (BIS) and behavioral activation (BAS), is frequently used to represent basic dimensions of psychopathology. However, notably few investigations have examined the link between the BIS/BAS and symptoms of personality disorder (PD). Although the Fight-Flight-Freeze System has emerged in the revised model as an important aspect of motivation, the BIS (linked to anxiety) and BAS (linked to impulsivity) have been the primary foci. The current investigation uses a dimensional measure of PD, the schedule for nonadaptive and adaptive personality (SNAP; Clark, 1993) applied to two independent samples of English-speaking participants: undergraduates (n = 276) and clinical patients (n = 47). Results were consistent across both samples, demonstrating that symptoms of Cluster B PDs are indicative of high BAS levels whereas symptoms of Cluster C PDs are characterized by high BIS levels.     

Big-five personality and BIS/BAS traits as predictors of career exploration: The mediation role of career adaptability

Based on career construction theory, the current research examined whether career adaptability mediates the relations of the personality traits (Five-Factor Model personality traits and behavioral inhibition and activation systems (BIS/BAS)) to career exploration behavior. Results from a survey in Chinese university students (N = 264) showed that career exploration correlated negatively with neuroticism, and positively with openness to experience, extroversion, agreeableness, conscientiousness and BAS. Results of regression analyses further showed that openness to experience, agreeableness, conscientiousness and BAS served as the strongest predictors for career exploration. In addition, career adaptability was shown to be a key mediator for the relationships between personality traits and career exploration behavior. Career concern and career curiosity were the more important dimensions in the mediation model. These findings advance current understandings on how different personality traits predict career exploration behavior.     

Covering all the BAS’s: A closer look at the links between BIS,BAS, and socio-emotional functioning in childhood

The purpose of this study was to investigate associations between the BIS, BAS, and socio-emotional functioning in childhood. Participants were 368 children (181 boys) ranging in age from 9 to 13 years (M_age = 10.16, SD = .95). Children provided self-report assessments of BIS/BAS sensitivity, indices of internalizing problems (e.g., depression, social anxiety, loneliness), and perceptions of their peer relations. Parents also rated child internalizing and externalizing problems. Results from confirmatory factor-analysis suggested that the three-factor solution for the BAS (typically reported in adult samples) provided a better fit of the data than a one-factor (typically employed in previous studies with children). Moreover, BAS subscales were associated differentially with different indices of socio-emotional functioning. Support for the joint subsystems hypothesis was also found, with specific BAS subscales serving as moderators of the relations between the BIS and socio-emotional functioning.     

Neuroticism,BIS, and reactivity to discrete negative mood inductions

Research has established relationships between the personality dimensions of neuroticism and BIS and broad negative emotional reactivity. However, few researchers have examined the relationships among neuroticism, BIS, and discrete negative emotional reactivities. The present study examined whether individuals scoring high on neuroticism and BIS were more reactive across four discrete negative mood inductions, relative to those scoring low on these traits. Participants (n = 166) completed personality questionnaires, measures of current mood, viewed a specific mood-inducing film clip (sadness, anger, fear or disgust) and then reported their moods a second time. Results revealed that neuroticism/BIS was associated with high reactivity to the fear and sadness inductions. Neuroticism/BIS did not predict anger or disgust reactivity, but neuroticism/BIS and extraversion/BAS interacted in predicting anger. Although further research is needed to extend generalizability, it appears that neuroticism and BIS predict negative emotional reactivity broadly, but not ubiquitously.     

Coping mediates relationships between reinforcement sensitivity and symptoms of psychopathology

Limited research has evaluated whether coping strategies mediate the relationships between reinforcement sensitivity theory (RST) and symptoms of psychopathology. Undergraduates (n = 293) completed questionnaires assessing RST, coping, and symptoms of psychopathology. Consistent with our hypotheses, bootstrapping analyses indicated that emotion- and avoidance-focused coping mediated the relationship between high Behavioral Inhibition System (BIS) and depression, anxiety, and worry. Less problem-focused coping mediated the relationship between low Behavioral Approach System (BAS) and depression. Avoidance-focused coping mediated the effects of high BIS on drug and alcohol use whereas high BAS directly predicted alcohol and drug use. Unexpectedly, emotion-focused coping mediated the relationship between BAS and anxiety and worry. These results provide support for the hypothesis that personality variables are associated with psychopathology partially through coping.     

Self appraisal and behavioural activation in the prediction of hypomanic personality and depressive symptoms

Hypomanic personality is characterised by increased positive mood and energy but also more depression and greater risk of bipolar disorder. It is linked with positive self-appraisals for hypomania-relevant events and Behavioural Activation System (BAS) sensitivity such that hypomanic individuals tend preferentially towards goal-related activities. This study investigated relationships between positive and negative self-appraisal and BAS functioning and hypomanic personality and depressive symptoms. Participants (N = 231) completed measures of hypomanic personality, mood symptoms, dysfunctional attitudes, self-appraisal and behavioural activation/inhibition.Positive but not negative self-appraisal contributed to prediction of hypomanic personality as did higher BAS fun seeking and lower Behavioural Inhibition System (BIS) scores. Conversely, negative self-appraisal was positively predictive of current depressive mood, whilst BAS reward responsiveness was negatively predictive. There are specific relationships between positive and negative appraisal styles and hypomanic personality and depressive mood, respectively. The findings of complimentary contributions from appraisal style, BAS and BIS to prediction of hypomanic personality are relevant to developing a better understanding of risk factors for bipolar disorder.     

Throwing light on the dark side of personality: Reinforcement sensitivity theory and primary/secondary psychopathy in a student population

In a student sample, we examined two major issues in relation to primary/secondary subtypes of psychopathy and the reinforcement sensitivity theory of personality: the roles played by (a) fear (related to the fight-flight-freeze system, FFFS) and anxiety (related to the behavioural inhibition system, BIS), and (b) different aspects of the behavioural approach system (BAS). Largely consistent with Corr’s (2010a) proposal concerning the neuropsychological deficits associated with the psychoticism-psychopathy continuum, results confirmed that low BIS activity was associated with both primary and secondary psychopathy; whereas low FFFS activity was associated with only primary psychopathy. In relation to the BAS, reward sensitivity and drive were positively related to primary psychopathy; whereas Fun Seeking was negatively related to primary psychopathy but positively related to secondary psychopathy. These results represent a more nuanced picture of FFFS/BIS/BAS and dispositional psychopathy in a student sample. Specifically, they challenge the view that low BIS is preferentially associated with primary psychopathy and a high BAS is preferentially associated with secondary psychopathy. Further work is needed to confirm that these findings extend to clinical and forensic psychopathy populations.     

The effect of prenatal androgen exposure on the development of neural reactivity systems: A study of the HEXACO Personality Inventory

The ratio of the lengths of the second and fourth digits of hands (2D:4D) seems to vary as a function of systematic differences in prenatal androgen exposure (Hönekopp & Watson, 2010). The 2D:4D ratio has been shown to be related to a variety of personality attributes. This study predicted that 2D:4D would covary with scores on the emotionality dimension of the six-facet HEXACO personality assessment, due to emotionality’s relationship with neural reactivity systems controlled by the amygdala (Hines, Allen, & Gorski, 1992), but that 2D:4D would relate to no other facet. Consistent with hypotheses, data showed that men had smaller ratios than women on both the right, t(405) = 2.84, p < .05, d = .28, and left hands, t(405) = 4.51, p < .05, d = .45, and the relationship between 2D:4D and emotionality was outside of sampling error of zero, r = .18, p < .001. Additionally, 2D:4D was unrelated to the remaining HEXACO facets. Findings suggest that prenatal testosterone exposure has an organizing effect on personality traits.     

Carver and Whites’ BIS/FFFS/BAS scales and domains and facets of the Five Factor Model of personality

Few empirical studies have investigated the relationship between Gray’s Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) of personality. In a large sample of undergraduates (N = 779), we examined the relationship between FFM domains and facets and the revised RST (see Gray & McNaughton, 2000). Regression and partial correlation analyses indicated that only FFM Agreeableness discriminates between the BIS and FFFS. Other differences at the facet level were found for Neuroticism facets of Self-Consciousness and Angry Hostility (negatively), Agreeableness facets of Compliance and Modesty, and Conscientiousness facets of Self-Discipline and Deliberation. These findings emphasize social inhibition and constraint in the BIS, compared to the FFFS.     

Individual differences and propensity to engage with in-vehicle distractions - A self-report survey

Ratings of severity and frequency of engagement with distracting driver behaviours are reported in this paper. Survey data were collected using an anonymous online questionnaire. Four hundred eighty-two respondents contributed to the survey during a 2 month data collection period. Results indicate that the three behaviours rated as most distracting when driving were (i) writing text messages (41%), (ii) reading text messages (62%), and (iii) using a cellular telephone hand-held (52%). The three most frequently reported distracting behaviours that resulted in accidents were (i) ‘interaction with child passengers’ 2.1% (near misses = 7.5%), (ii) both, route guidance destination entry with 2% (near misses = 2.8%) and use of an ‘… add-on media device, e.g., an iPod’ with 2% (near misses = 3.9%), and (iii) the three items ‘reading a text message’, ‘following advice from a route guidance system’, and ‘interaction with pets’, all with 1.7% of respondents reporting an accident when undertaking the activity (with 6.5%, 3%, and 2.2% respectively for near misses). Two hierarchical regression models were explored. The first introducing personal factors, i.e., age, extraversion, agreeableness, conscientiousness, emotional stability and intellect (R² = 0.131, p < 0.001). The second controlled for variables in the first model and introduced driver-related variables, mileage, penalty points, and frequency of accidents with assumed responsibility (R² = 0.253, p < 0.001). This model identified age, extraversion, mileage, penalty points and accidents all to be significant predictors of engagement with unnecessary distractions. The data presents a picture of widespread awareness of, and engagement with, distracting behaviours by drivers in the United Kingdom. Findings from the hierarchical regressions suggest scope may exist to mediate the levels of distracting behaviours by exploring individual differences and driving styles.     

The effects of behavioral inhibition/approach system as predictors of Internet addiction in adolescents

This study aimed to determine how the Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS) affect Internet addiction in adolescents. Two hundred and eleven high school students participated in this study and completed the Young’s Internet Addiction Test (IAT), BIS/BAS scales, and several self-administered questionnaires about depression, anxiety, and impulsivity. Hierarchical regressions showed that BIS and BAS × BIS emerged as significant predictors of IAT; however, only BAS-fun seeking subscale predicted IAT among BAS related subscales. In further analyses, the BAS-fun seeking subscale was mediated by impulsivity and anxiety, and BIS was mediated by anxiety and depression. The current findings imply that BIS and BAS interdependently influence vulnerability to Internet addiction through both shared (anxiety) and different (depression and impulsivity, respectively) pathways.     

From BIS/BAS to the big five

Gray ( 1987 ) proposed two systems that underlie much of our behaviour and personality. One system relates to avoidance or withdrawal behaviour, called the Behavioural Inhibition System (BIS), whereas the other system relates to approach behaviour, called the Behavioural Approach System (BAS). In two samples, it was investigated whether individual differences in surface of personality as described by the Big Five can be explained by BIS/BAS. Neuroticism and Extraversion could be explained well by BIS/BAS, but also for Agreeableness and Conscientiousness consistent findings were obtained. Copyright © 2006 John Wiley & Sons, Ltd.     

Personality types and behavioural activation and inhibition in adolescents

A hypothesis relating personality types to activity of the Behavioural Approach System (BAS) and the Behavioural Inhibition System (BIS) was tested in a sample of 1015 10–18-year-old adolescents. According to this hypothesis, Undercontrollers could be characterized as individuals with overactive BAS, Overcontrollers as individuals with overactive BIS, and Resilients as individuals with low activity of both systems. These predictions were generally confirmed. Psychometrically measured BAS and BIS appeared to be the strongest predictors of Undercontrolled and Overcontrolled prototypes, respectively. Resilients were characterized by low scores on both dimensions.     

Disagreeable narcissism mediates an effect of BAS on addictive behaviors

Some forms of personality dysfunction that are associated with substance use and other externalizing behaviors, such as Narcissistic Personality Disorder, are characterized by low five-factor Agreeableness. Low Agreeableness and high Extraversion are both associated with the Behavioral Approach System in the revised Reinforcement Sensitivity Theory of Personality (RST; McNaughton & Corr, 2008). Meta-analyses examining personality predictors of Substance Use Disorders (Kotov et al., 2010) and Pathological Gambling (MacLaren et al., 2011) have implicated low Agreeableness but not Extraversion. In the present study, we sampled undergraduate students (N = 346) to examine relationships between two aspects of grandiose narcissism measured by the Narcissistic Personality Inventory (NPI), approach motivation measured by the BIS/BAS scales, and self-reported addictive behaviors. Disagreeable and Extraverted subscales of the NPI were examined for possible mediation of associations between BAS and addictive behaviors. The more disagreeable aspect of narcissism mediated the effects of BAS on drug use, gambling, sex, and maladaptive intimate relationships. These results suggest that one mechanism through which the Behavioral Approach System may promote addictive behavior among grandiose Narcissists is through its association with their aggressive and antagonistic interpersonal style.     

Association between the HTR2B gene and the personality trait of fun seeking

Previous research reported that a rare serotonin receptor 2B gene (HTR2B) stop codon mutation predisposes subjects to severe impulsivity and novelty seeking. In this study, we expanded this previous work by testing six single nucleotide polymorphisms (SNPs) within the HTR2B gene for potential associations with the behavioral inhibition system (BIS) and the three components of the behavioral approach systems (BAS: fun seeking, drive, and reward responsiveness) in a Han Chinese sample (N = 478). Association analysis for individual SNPs indicated that four of the six SNPs (i.e., rs6437000, rs10194776, rs16827801, and rs1549339) were significantly associated with BAS fun seeking (p = .0003–.0022). Haplotype-based association analysis revealed that fun seeking was positively associated with haplotype A–A–G–A for SNPs rs6437000–rs10194776–rs16827801–rs1549339 (p = .0002), which survived Bonferroni correction. Except for the association between BAS reward responsiveness and rs16827801 (p = .005), no other association was found for BAS drive, BAS reward responsiveness, or BIS. This study provides the first evidence for the involvement of the HTR2B gene in BAS fun seeking. A better understanding of the genetic basis of the BIS and BAS would allow us to develop more effective diagnosis, treatment, and prevention of impulsive behavioral problems.     

Personality and action control: BAS Reward predicts motor control accuracy

Theoretically, the processes involved in approach motivation and action control should overlap. In both cases, a person must commit to a goal, identify a goal target, and seek to reduce discrepancies between the self and this goal target on a somewhat continuous basis. These ideas motivated three studies (total N = 253) in which personality differences in the behavioral approach system (BAS) and the behavioral inhibition system (BIS) were assessed as potential predictors of performance in an objective motor control task. People high in BAS Reward had markedly better motor control (i.e., smaller distances from targets) than people low in BAS Reward. This was true across a variety of affective priming conditions. The other components of BAS and BIS, by contrast, were inconsistent predictors. The results support both reward-based and functional perspectives of the BAS in the context of a cybernetic view of how self-regulation by approach operates.     

Gender differences in rumination: A meta-analysis

Starting in adolescence and continuing through adulthood, women are twice as likely as men to experience depression. According to the response styles theory (RST), gender differences in depression result, in part, from women’s tendency to ruminate more than men. A meta-analysis was performed to evaluate gender differences in rumination in adults (k = 59; N = 14,321); additionally, an analysis of subtypes of rumination – brooding and reflection – was conducted (k = 23). Fixed effects analyses indicated that women scored higher than men in rumination (d = .24, p < .01, SEd = .02), brooding (d = .19, p < .01, SEd = .03) and reflection (d = .17, p < .01, SEd = .03); there was no evidence of heterogeneity or publication bias across studies for these effect sizes. Although statistically significant, the effect sizes for gender differences in rumination were small in magnitude. Results are discussed with respect to the RST and gender differences in depression.     

Heart rate variability and drawing impairment in hypoxemic COPD

We studied 54 patients with hypoxemic chronic obstructive pulmonary disease (COPD). The Mini Mental State Examination and the Mental Deterioration Battery were used for neuropsychological assessment. Heart rate variability (HRV) was assessed based on 24-h Holter ECG recording. Mann–Whitney test was used to compare HRV parameters of patients performing normally or abnormally on individual neuropsychological tasks. Spearman’s rho was used to investigate the correlations between HRV parameters and neuropsychological scores, indexes of health status or COPD severity. Patients with defective performance at copying drawings with landmarks (CDL) test (N = 23) had lower very low frequency (VLF) power with respect to patients with normal performance (N = 31) (24 h: median 213; interquartile range 120–282 vs. 309; 188–431 ms², p = 0.043; daytime: 202; 111–292 vs. 342; 194–397 ms², p = 0.039). The CDL score correlated with the VLF power (24 h: ρ = 0.27, p = 0.049; daytime: ρ = 0.30, p = 0.028), and the normalized low frequency/high frequency (LF/HF) ratio (24 h: ρ = 0.27, p = 0.05; daytime: ρ = 0.33, p = 0.015). Sympathetic modulation decreased for increasing severity of COPD. In conclusion, drawing impairment correlates with depressed sympathetic modulation in patients with COPD, and both might be indexes of COPD severity.
