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.

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 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.

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.

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.

Emotional Stroop Performance for Masked Angry Faces: It's BAS, Not BIS.

Theoretical models concerning selective attention to emotional stimuli predict heightened vigilance to angry faces in people with heightened trait anxiety or greater activity of the Behavioral Inhibition System (BIS). Recent evidence from electroencephalographic lateralization and affect studies and from studies assessing attentional biases to angry faces suggest, however, that heightened anger and activity of the Behavioral Activation System (BAS) should predict vigilant responding to angry faces. Social anxiety should predict avoidance of angry faces. Results from a masked emotional Stroop task verified these hypotheses, but an unmasked emotional Stroop provided no reliable relations. This dissociation confirms earlier claims that masked emotional Stroop performance is impervious to conscious control over the cognitive-emotional processes, as measured by the Stroop task.

Behavioral observation scales for measuring children's distress: The effects of increased methodological rigor.

In Exp I, the Observation Scale of Behavioral Distress (OSBD), a revision of the Procedure Behavioral Rating Scale, was used to evaluate 42 pediatric cancer patients undergoing bone marrow aspiration procedures. In Exp II, 31 pediatric cancer patients were evaluated using the same procedures as in Exp I. In both experiments, parents rated their child's anxiety. Results show that Ss habituated but that the OSBD had little effect on validity or habituation data. The failure to find significant differences in validity measures with an increase in sophistication of the measurement techniques may be related to the nature of the situation and to types of behaviors recorded. In acute and intense situations, gross behavioral recordings of the presence or absence of behaviors may be sufficient. (3 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The dominance of behavioural activation over behavioural inhibition in conduct disordered boys with or without attention deficit hyperactivity disorder

On the basis of Gray's theory, Quay suggested that conduct disorder (CD) is associated with a Behavioural Activation System (BAS) that dominates over the Behavioural Inhibition System (BIS), whereas attention deficit hyperactivity disorder (ADHD) is characterised by an underactive BIS. Two studies were conducted to test the hypothesis that the dominance of the BAS over the BIS is more pronounced in CD comorbid with ADHD (CD/ADHD) than in CD alone. First of all, a response perseveration task was used, i.e. the door-opening task (Daugherty & Quay, 1991). In this game, the subject chooses either to open the next door or to stop playing; there is a steadily increasing ratio of punished responses to rewarded responses and a large number of doors opened is indicative of response perseveration. As expected, a steady increase in the number of doors opened was found across normal control (NC) boys, CD boys, and CD/ADHD boys (NC < CD < CD/ADHD). Second, the dominance of the BAS over the BIS was examined by observing the social behaviour of the child in interaction with a research assistant who alternately activated the BAS and the BIS while a game was played. The behaviour of the children was analysed according to ethological methods. Group differences in the frequencies of three out of five behavioural categories were in line with the results of the door-opening task (NC < CD < CD/ADHD).     

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.

Taxometric and factor analytic models of anxiety sensitivity: Integrating approaches to latent structural research.

This study represents an effort to better understand the latent structure of anxiety sensitivity (AS), as indexed by the 16-item Anxiety Sensitivity Index (ASI; S. Reiss, R. A. Peterson, M. Gursky, & R. J. McNally, 1986), by using taxometric and factor-analytic approaches in an integrative manner. Taxometric analyses indicated that AS has a taxonic latent class structure (i.e., a dichotomous latent class structure) in a large sample of North American adults (N = 2,515). As predicted, confirmatory factor analyses indicated that a multidimensional 3-factor model of AS provided a good fit for the AS complement class (normative or low-risk form) but not the AS taxon class (high-risk form). Exploratory factor analytic results suggested that the AS taxon may demonstrate a unique, unidimensional factor solution, though there are alternative indications that it may be characterized by a 2-factor solution. Findings suggest that the latent structural nature of AS can be conceptualized as a taxonic latent class structure composed of 2 types or forms of AS, each of these forms characterized by its own unique latent continuity and dimensional structure.

Subjective effects of transdermal nicotine among nonsmokers.

The subjective experience of nicotine, which may be influenced by personality traits as well as environmental factors, may be important for understanding the factors associated with the initiation and maintenance of nicotine dependence. The present study examined the effects of 7 mg transdermal nicotine among a relatively large sample (n = 91; 44 women) of college-aged nonsmokers. Using a placebo controlled, double-blind, within-subjects design, nicotine’s effects were examined at rest and again after participants completed a sustained attention task. Sex and personality factors (Behavioral Inhibition and Behavioral Approach; BIS/BAS Scales; Carver & White, 1994) were examined as potential moderators. Overall, the effects of nicotine were generally modest and unpleasant. In the context of the cognitive task, nicotine increased nausea and negative affect but reduced fatigue, relative to placebo. In contrast, effects of nicotine during the initial 4 hr of patch administration, in which participants were in their natural environments, were moderated by individual differences in behavioral approach. Neither behavioral inhibition nor gender reliably moderated any subjective effects of nicotine. The present work suggests transdermal nicotine exerts only modest, mostly negative effects among nonsmokers. Future work should examine both contextual and personality moderators in large samples of participants who are exposed to nicotine through multiple routes of administration.

The structure of negative emotions in a clinical sample of children and adolescents.

The authors sought to define the latent factors associated with childhood anxiety and depression, using a structural equations/confirmatory factor-analytic approach involving multiple informants (i.e., parent and child report) of symptoms. A sample of 216 children and adolescents with diagnoses of an anxiety disorder or comorbid anxiety and mood disorders and their parents were administered measures of childhood fear, anxiety, and depression. Results of comparative modeling best supported 3-factor solutions (fear, anxiety, and depression) that were consistent with recent conceptual models of anxiety and depression (e.g., tripartite model). Results also suggested that 3 widely used measures of childhood negative emotion are conceptually heterogeneous (containing item sets that loaded on different latent factors) . Implications for the assessment of childhood negative emotions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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)     

Paranoid personality has a dimensional latent structure: Taxometric analyses of community and clinical samples.

Although paranoid personality is one of the most commonly diagnosed personality disorders and is associated with numerous negative life consequences, relatively little is known about the structural properties of this condition. This study examines whether paranoid personality traits represent a latent dimension or a discrete class (i.e., taxon). In Study 1, the authors conducted taxometric analyses of paranoid personality disorder criteria in a sample of 731 patients participating in the Collaborative Longitudinal Study of Personality Disorders project (Gunderson et al., 2000) who had been administered a semistructured diagnostic interview for personality disorders according to criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). In Study 2, the authors conducted parallel analyses of the Paranoia scale of the Personality Assessment Inventory (PAI; L. C. Morey, 2007), using data from the PAI community and clinical normative databases. Analyses across both self-report and interview-based indicators offered compelling support for a dimensional structure. Additionally, analyses of external correlates in these data sets suggested that dimensional models demonstrated stronger validity coefficients with criterion measures than did dichotomous models.

Bioimpedance spectroscopy technique: intra-, extracellular, and total body water

The purpose of this study was to test the validity of a multiple frequency bioimpedance spectroscopy (BIS) technique that estimates extracellular fluid volume (ECV), intracellular fluid volume (ICV), and total body water (TBW). Thirteen healthy males (mean +/- SD: age, 23 +/- 3 yr; body mass, 80.6 +/- 14.7 kg) had their TBW and ECV measured by ingesting dilution tracers (7.27 g deuterium oxide, 1.70 g sodium bromide; blood samples at 0 and 4 h). ICV was calculated as TBW minus ECV. Impedance was measured (50-500 kHz) at rest, on a nonconducting surface, with a BIS analyzer. Electrode placement, posture, exercise, food/fluid intake, and ambient temperature were controlled. Dilution measures (TBW, 51.00 +/- 9.30; ECV, 19.88 +/- 3.14; ICV, 31.12 +/- 6.80 L) and BIS volumes (TBW, 50.03 +/- 7.67; ECV, 20.95 +/- 3.33; ICV, 29.04 +/- 4.51 L) were significantly different for ECV (P < 0.01) and ICV (P < 0.05); some individual differences were large. The correlation coefficients of dilution versus BIS volumes (r = 0.93 to 0.96) were significant at P < 0.0001; SEEs were: TBW, 2.23 L; ECV, 1.26 L; and ICV, 1.71 L. We concluded that BIS is valid for between-subject comparisons of body fluid compartments, is appropriate in clinical settings where change in ECV/ICV ratio is important, and should be used by comparing the required level of accuracy to the inherent technique error/variance.     

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)     

Responsiveness to threats and incentives, expectancy of recurrence, and distress and disengagement: Moderator effects in women with early stage breast cancer.

Models of neurobiological systems linking personality, motivation, and emotion can be integrated with the expectancy construct to suggest hypotheses about distress and giving up in response to adversity. In 220 women with breast cancer, threat responsiveness—sensitivity of the behavioral inhibition system (BIS)—and incentive responsiveness—sensitivity of the behavioral activation system (BAS)—and expectancies about cancer recurrence were measured. It was predicted and found that high BIS sensitivity interacted with recurrence expectancy to predict elevated distress and disengagement. Low BAS sensitivity (reward responsiveness) also interacted with expectancy of recurrence to predict elevated disengagement. In contrast, high BAS sensitivity (fun seeking) interacted with recurrence expectancy to predict elevated distress. Discussion centers on theoretical implications and possible applications.

Behavioral disinhibition: Liability for externalizing spectrum disorders and its genetic and environmental relation to response inhibition across adolescence.

Behavioral disinhibition has been characterized as a generalized vulnerability to externalizing disorders. Despite increasing evidence for its validity and heritability, the structural stability of behavioral disinhibition across adolescence and the strength and etiology of its relation to executive functions have not been studied. In this multivariate twin study, the authors assessed behavioral disinhibition using measures tapping substance use, conduct disorder, attention-deficit/hyperactivity disorder (ADHD), and novelty seeking at ages 12 and 17. Executive functions were assessed with laboratory-based cognitive tasks at age 17. Results indicated that, at age 12, behavioral disinhibition was dominated by ADHD and conduct problems and was highly heritable. At age 17, the contributions of the 4 components were more balanced, and the proportion of variance attributable to genetic factors was somewhat smaller, with additional variance due to shared environmental influences. At both ages, behavioral disinhibition was more closely related to response inhibition than other executive functions (working memory updating and task-set shifting), and this relationship was primarily genetic in origin. These results highlight the dynamic nature of behavioral disinhibition across adolescence and suggest that response inhibition may be an important mechanism underlying vulnerability to disinhibitory psychopathology.

Behavioral and cardiovascular responses to interpersonal challenges among male offspring of essential hypertensives.

Behavioral, cardiovascular, and self-report measures of cognitive and affective responses to 2 interpersonal challenges were examined among 20 men with a positive (FH+) and 20 with a negative (FH–) family history of hypertension. Heart rate (HR) and blood pressure (BP) were measured throughout the laboratory session; Ss were requested to self-report positive and negative conditions, state anger, and state anxiety that occurred during interactions with a male and female confederate. Behavioral responses to interpersonal tasks were videotaped, coded, and categorized into 4 major groupings (positive verbal, positive nonverbal, negative verbal, and negative nonverbal). FH+ individuals exhibited significantly higher resting HR and systolic BP reactivity to both interactions than FH– counterparts. Analyses of behavioral responses for both interactions revealed significantly more negative verbal and nonverbal behavior and less positive nonverbal behavior among FH+ as compared with FH– Ss.

Influences of beliefs and personality disorders on treatment outcome in anxiety patients.

The present study investigated the effects of personality disorders (PDs) and specific PD-related beliefs on the results of (cognitive-)behavioral therapy for anxiety disorders in a sample of 398 outpatients. The authors used a prospective design in which relationships between PD variables before treatment and outcome measures at posttest and follow-up were evaluated with multilevel analyses. People with PDs and PD-related beliefs reported higher symptom levels at outcome. However, these effects were not as strong as might be expected on the basis of prevailing clinical thought in this area. Dropout rates were not influenced by the presence of 1 or more PDs or PD-related beliefs. Results indicate that treatment of anxiety disorders in patients with concomitant one or more PDs is appropriate. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
