Behavioral inhibition, behavioral activation, and affective responses to impending reward and punishment: The BIS/BAS Scales.

J. A. Gray (1981, 1982) holds that 2 general motivational systems underlie behavior and affect: a behavioral inhibition system (BIS) and a behavioral activation system (BAS). Self-report scales to assess dispositional BIS and BAS sensitivities were created. Scale development (Study 1) and convergent and discriminant validity in the form of correlations with alternative measures are reported (Study 2). In Study 3, a situation in which Ss anticipated a punishment was created. Controlling for initial nervousness, Ss high in BIS sensitivity (assessed earlier) were more nervous than those low in BIS sensitivity. In Study 4, a situation in which Ss anticipated a reward was created. Controlling for initial happiness, Ss high in BAS sensitivity (Reward Responsiveness and Drive scales) were happier than those low in BAS sensitivity. In each case the new scales predicted better than an alternative measure. Discussion is focused on conceptual implications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Behavioral inhibition and activation systems: Differences in substance use expectancy organization and activation in memory.

We used multidimensional scaling to model the semantic network of alcohol and marijuana expectancies (N = 897). Preference mapping was used to estimate vectors representing patterns of activation through the network as a function of levels of behavioral inhibition (BIS) and behavioral activation (BAS). Individuals with low BIS combined with high BAS levels exhibited patterns of activation emphasizing behavioral activation similar to heavier drug users in previous research. High BIS, low BAS individuals exhibited activation patterns with greater emphasis on inhibitory expectancies similar to low-level users. Differences in expectancy activation patterns were maintained after controlling for substance use and gender. Individual differences in BIS/BAS are associated with the organization of semantic networks and patterns of activation of expectancies contributing to differences in substance use behavior.

Negative Affects Deriving From the Behavioral Approach System.

Does the behavioral approach system (BAS) relate to the experience of any negative affects, or are all negative affects tied to the behavioral inhibition system (BIS)? In Study 1, self-reported Fun Seeking predicted reports of greater frustration and sadness after frustrative nonreward. In Study 2, self-reported Reward Responsiveness predicted reports of greater anger in response to scenarios. In Study 3, self-reported Drive predicted reports of greater anger after the terrorist attacks of September 11, 2001. In no case did BIS sensitivity contribute uniquely to these affects, though BIS predicted nervousness in Study 2 and fear in Study 3. Discussion focuses on the role of frustration and anger in effortful pursuit of goals and depressed affect in disengagement from goals.

Behavioral activation and inhibition systems and the severity and course of depression.

Theorists have proposed that depression is associated with abnormalities in the behavioral activation (BAS) and behavioral inhibition (BIS) systems. In particular, depressed individuals are hypothesized to exhibit deficient BAS and overactive BIS functioning. Self-reported levels of BAS and BIS were examined in 62 depressed participants and 27 nondepressed controls. Clinical functioning was assessed at intake and at 8-month follow-up. Relative to nondepressed controls, depressed participants reported lower BAS levels and higher BIS levels. Within the depressed group, lower BAS levels were associated with greater concurrent depression severity and predicted worse 8-month outcome. Levels of both BIS and BAS showed considerable stability over time and clinical state. Overall, results suggest that BAS dysregulation exacerbates the presentation and course of depressive illness.

The relations of motivational traits with workplace deviance.

The authors developed and tested new theoretical relations between approach and avoidance motivational traits and deviant work behaviors. Approach motivation was divided into 3 traits: personal mastery (i.e., desire to achieve), competitive excellence (i.e., desire to perform better than others), and behavioral activation system (BAS) sensitivity (i.e., responsiveness to rewards). Avoidance motivation, which reflects one's sensitivity to negative stimuli and the desire to escape such stimuli, was conceptualized as a unitary construct. Using structural equation modeling, the authors examined the relations of these 4 motivational traits with interpersonal and organizational deviance in a sample of primarily part-time employees. For the approach motivation traits, results showed that personal mastery was negatively related to interpersonal and organizational deviance, BAS sensitivity was positively related to interpersonal and organizational deviance, and competitive excellence was unrelated to both types of workplace deviance. Finally, avoidance motivation was positively related to organizational deviance and interacted with organizational constraints to predict interpersonal deviance.

Validating a Distinction Between Primary and Secondary Psychopathy With Measures of Gray's BIS and BAS Constructs.

Investigators commonly distinguish between primary and secondary psychopathy (H. Cleckley, 1976; D.T. Lykken, 1995), though there is a lack of consensus regarding the best means to achieve this distinction. To address the validity of using R. D. Hare's (2003) Psychopathy Checklist and the G. Welsh (1956) Anxiety Scale for this purpose, the authors used 2 measures of J. A. Gray's (1987) behavioral inhibition system/behavioral activation system (BIS/BAS). Following D. T. Lykken (1995) and D. C. Fowles (1980), the authors hypothesized that primary psychopathy would be associated with a weak BIS and a normal BAS, whereas secondary psychopathy would be associated with a strong BAS and a normal BIS. Results for primary psychopathy were as predicted. Results for secondary psychopathy clearly supported the strong BAS prediction but provided mixed support for the normal BIS prediction.

Personality and Emotion: Test of Gray's Personality Theory by Means of an fMRI Study.

Although it is known that there are fundamental personality differences in the behavioral responses to emotional stimuli, traits have scarcely been investigated in this context by means of functional imaging studies. To maximize the variance with respect to personality, the authors tested 12 control subjects and 12 subjects who had sadomasochistic experiences with respect to the relationship between J. A. Gray's (1970) personality dimensions, the behavioral approach system (BAS) and the behavioral inhibition system (BIS), and brain activity in regions of interest. The BIS was associated with activity in numerous brain areas in response to fear, disgust, and erotic visual stimuli, whereas few associations could he detected between the BAS and brain activity in response to disgust and erotic stimuli.

Clarifying the factors that undermine behavioral inhibition system functioning in psychopathy.

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 assessed with the Psychopathy Checklist–Revised (PCL–R; Hare, 2003). In addition, we tested the hypothesis that the effects of working memory load on BIS functioning would interact differentially with the PCL–R factors. Replicating previous results, psychopathic offenders were less sensitive to BIS-related cues than controls. As predicted, working memory load interacted with Factor 2 (antisocial/impulsive), with higher scores predicting weaker BIS functioning under high-load though not low-load conditions. Results suggest new insights concerning the relationship among working memory, reward sensitivity, and BIS functioning in psychopathy.

Behavioral activation and inhibition in everyday life.

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 independent appetitive and aversive motivational systems, the Behavioral Activation System (BAS) and the Behavioral Inhibition System (BIS), moderated these relationships. Participants in Study 2 with higher BAS sensitivity reported more PA on average; those with more sensitive BIS reported more NA. Also, BIS moderated reactions to negative events, such that higher BIS sensitivity magnified reactions to negative events. Study 3 replicated these findings and showed that BAS predisposed people to experience more positive events. Results demonstrate the value of distinguishing within-person and between-person effects to clarify the functionally independent processes by which dispositional sensitivities influence affect.

The behavioral inhibition system and the verbal information pathway to children's fears.

The behavioral inhibition system (BIS) is the neurological substrate of trait anxiety and is linked to the development of anxiety disorders. Three experiments are reported that investigate the moderating influence of the BIS on 1 pathway to fear: threat information. In all studies, children were given verbal information about a set of novel animals, and their BIS sensitivity was measured. The results suggest that BIS sensitivity (a) facilitates attentional biases to stimuli associated with threat information and (b) facilitates behavioral avoidance of novel stimuli associated with threat information. This suggests a possible mechanism through which the BIS may promote the acquisition of animal fears. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Optimism, Perceived Risk of Breast Cancer, and Cancer Worry Among a Community-Based Sample of Women.

Optimism is frequently inversely associated with distress; however, less is known about the mechanisms underlying this relationship. Optimism can be defined as having a generalized positive expectancy about the future. The authors hypothesized that a specific expectancy might mediate the relationship between optimism and distress. That model was tested using perceived risk of breast cancer as a specific measure of expectancy and cancer worry as a measure of distress in a community-based sample of 1,366 women. It was hypothesized that optimism would be inversely associated with cancer worry and that perceived risk of breast cancer would mediate the relationship between optimism and cancer worry. Multiple regression analyses revealed that perceived risk partially mediated the relationship between optimism and cancer worry. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mood regulation expectancies, anxiety sensitivity, and emotional distress.

Mood regulation expectancy is a behavior–outcome response expectancy; anxiety sensitivity can be conceptualized as a stimulus–outcome response expectancy. Current expectancy models of emotion and distress focus on stimulus–outcome expectancies, potentially neglecting behavior–outcome expectancies. In a sample of 502 college students, measures of each expectancy were independently related to distress, measured by the Beck Depression Inventory and Trait Anxiety Inventory: Those with weak beliefs about their ability to regulate negative moods and strong beliefs that the experience of anxiety causes further negative consequences reported the highest levels of distress. Implications for integrating behavior–outcome and stimulus–outcome response expectancies in models of emotion are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

How coping mediates the effect of optimism on distress: A study of women with early stage breast cancer.

At diagnosis, 59 breast cancer patients reported on their overall optimism about life; 1 day presurgery, 10 days postsurgery, and at 3-, 6-, and 12-mo follow-ups, they reported their recent coping responses and distress levels. Optimism related inversely to distress at each point, even controlling for prior distress. Acceptance, positive reframing, and use of religion were the most common coping reactions; denial and behavioral disengagement were the least common reactions. Acceptance and the use of humor prospectively predicted lower distress; denial and disengagement predicted more distress. Path analyses suggested that several coping reactions played mediating roles in the effect of optimism on distress. Discussion centers on the role of various coping reactions in the process of adjustment, the mechanisms by which dispositional optimism vs pessimism appears to operate, third variable issues, and applied implications.

Psychometric Evaluation of the Behavioral Inhibition/Behavioral Activation Scales in a Large Sample of Outpatients With Anxiety and Mood Disorders.

The latent structure, reliability, and validity of the Behavioral Inhibition/Behavioral Activation Scales (BIS/BAS; C. L. Carver & T. L. White, 1994) were examined in a large sample of outpatients (N = 1,825) with anxiety and mood disorders. Four subsamples were used for exploratory and confirmatory factor analyses. In addition to generally upholding a latent structure found previously in nonclinical samples, results indicated measurement invariance of the BIS/BAS between genders and a higher order structure of the BAS scales. Convergent and discriminant validity of the BIS/BAS were supported by findings that the subscales correlated most strongly with measures of neighboring personality constructs (e.g., BIS with neuroticism, BAS with positive affect) than with measures of current anxiety and depression symptoms. Overall, the results support the psychometric properties of the BIS/BAS in this clinical sample. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Distinguishing BIS-mediated and BAS-mediated disinhibition mechanisms: A comparison of disinhibition models of Gray (1981, 1987) and of Patterson and Newman (1993).

The theoretical framework developed by J. A. Gray (1981, 1987a, 1987b) was used to study disinhibitory behavior. Using a point-scoring reaction time procedure, 4 different experiments were conducted to differentiate 2 disinhibitory mechanisms associated with the behavioral activation system (BAS) and the behavioral inhibition system (BIS). Consistent with the work of C. M. Patterson and J. P. Newman (1993), the BAS-mediated mechanism was related to a lack of inhibition in reward-directed behavior after introducing an occasional aversive contingency and to deficits in learning from aversive cues when responding for reward (Experiments 1–3). The BIS-mediated mechanism was related to a higher ability to extinguish aversive associations (Experiment 1), a lower aversive generalization gradient (Experiment 3), and a lower interference with appetitive behavior in the presence of aversive stimuli (Experiment 4).

Bipolar spectrum–substance use co-occurrence: Behavioral approach system (BAS) sensitivity and impulsiveness as shared personality vulnerabilities.

Bipolar disorders and substance use disorders (SUDs) show high co-occurrence. One explanation for this co-occurrence may be common personality vulnerabilities involved in both. The authors tested whether high behavioral approach system (BAS) sensitivity and impulsiveness are shared personality vulnerabilities in bipolar spectrum disorders and substance use problems and their co-occurrence in a longitudinal study of 132 individuals on the bipolar spectrum and 153 control participants. At Time 1, participants completed the Behavioral Inhibition System/BAS Scales and the Impulsive Nonconformity Scale. Substance use problems were assessed via the Michigan Alcoholism Screening Test and the Drug Abuse Screening Test at 4-month intervals for 1 year. Participants with bipolar disorder had higher rates of lifetime SUDs and substance use problems during the follow-up, relative to control participants. In line with hypotheses, higher BAS sensitivity and impulsiveness predicted bipolar status and increased substance use problems prospectively. BAS total, BAS Fun Seeking, and impulsiveness mediated the association between bipolar spectrum status and prospective substance use problems, with impulsiveness as the most important mediator. High BAS sensitivity and impulsiveness may represent shared personality vulnerabilities for both disorders and may partially account for their co-occurrence.

A multimethod investigation of the Behavioral Activation System in bipolar disorder.

Dysregulation in behavioral activation system (BAS) activity has been implicated in the pathogenesis of bipolar disorder (BPD). To characterize BAS activity and related facets in this disorder, the authors compared 59 participants with BPD to 44 controls on multiple measures of BAS activity, including a standardized behavioral task, self-reports, and electroencephalographic indexes of regional cortical activity. Levels of putative BAS activity differed depending on assessment strategy. When a behavioral task indexing reward sensitivity was used, euthymic BPD patients showed evidence of higher BAS activity than either control participants or patients who were in a mood episode. Following a mood induction procedure designed to elicit BAS activity, currently episodic patients showed relatively greater left anterior cortical activity than either euthymic or control participants. Implications of the findings for future research on BPD vulnerability are described. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Behavioral approach system (BAS)–relevant cognitive styles and bipolar spectrum disorders: Concurrent and prospective associations.

The authors examined concurrent and prospective associations of behavioral approach system (BAS)–relevant and non-BAS-relevant cognitive styles with bipolar spectrum disorders. Controlling for depressive and hypomanic/manic symptoms, 195 individuals with bipolar spectrum disorders scored higher than 194 demographically similar normal controls on BAS sensitivity and BAS-relevant cognitive dimensions of performance concerns, autonomy, and self-criticism, but not on behavioral inhibition system sensitivity and non-BAS-relevant dimensions of approval seeking, sociotropy, and dependency. Moreover, group differences on autonomy fully mediated the association between higher BAS sensitivity and bipolar status. In addition, only BAS-related cognitive dimensions predicted the likelihood of onset of depressive and hypomanic/manic episodes among the bipolar individuals over a 3.2-year follow-up, controlling for initial symptoms and past history of mood episodes. Higher autonomy and self-criticism predicted a greater likelihood of hypomanic/manic episodes, and higher autonomy predicted a lower likelihood of major depressive episodes. In addition, autonomy mediated the associations between BAS sensitivity and prospective hypomanic/manic episodes. These findings suggest that individuals with bipolar spectrum disorders may exhibit a unique profile of BAS-relevant cognitive styles that influence the course of their mood episodes.

Behavioral activation sensitivity and resting frontal EEG asymmetry: Covariation of putative indicators related to risk for mood disorders.

Dispositional tendencies toward appetitive motivation have been hypothesized to be related to the development of psychopathology. Moreover, decreased left-frontal cortical activity has been reported in depression and has been related to low-trait positive affect and high-trait negative affect. The present study tested the hypothesis that relatively greater left- than right-frontal cortical activity would be related to heightened approach related dispositional tendencies. Resting frontal cortical asymmetrical activity, as measured by electroencephalographic activity in the alpha band, was examined in relation to the motivational response tendencies of a behavioral activation system (BAS) and a behavioral inhibition system (BIS), as measured by C. S. Carver and T. L. White's (see record 1995-00067-001) BIS-BAS self-report questionnaire. Results supported the hypothesis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Motivational correlates of thought content frequency and commitment.

Following evidence that cues related to Ss' current concerns control cognitive processing, this investigation probes the concern attributes that determine concern influence on thought content. The hypothesis—based on theory implicating affect in the initiation of thought segments, in determining incentive value, and in disengagement—predicted that the frequency with which goals are thought about varies with the value and imminence of the goal and with variables related to disrupted goal striving, other affect-related variables, and intensity of commitment. Concern Dimensions Questionnaires (CDQs) were administered to 153 undergraduates to assess recent thought content and provide ratings of things thought about. Thought-sampling evidence validated the CDQ measure of thought content frequency. The CDQ data confirmed the major hypotheses for all classes of variables, indicating that commitment varies with incentive value and expectancy and that thought is more often focused on goal pursuits involving threatened personal relationships, unexpected difficulties, and high degrees of commitment.
