BIS,BAS, and response conflict: Testing predictions of the revised reinforcement sensitivity theory

Gray’s (1970) reinforcement sensitivity theory (RST) was recently updated (Gray & McNaughton, 2000), but the changes have not received extensive empirical validation. The study tests three novel predictions of the revised RST. First, the behavioral activation system (BAS) is expected to be sensitive to both conditioned and unconditioned incentives. Second, the behavioral inhibition system (BIS) is expected to be sensitive to conflicting incentives such as between unconditioned and conditioned stimuli, and not to avoidance responses or aversive stimuli alone. Third, during approach-avoidance conflicts only, BAS is expected to moderate BIS responses to conflict such that individuals with high BAS show the strongest effect of BIS. In order to test these hypotheses, we developed a novel incentive task that crosses approach/avoidance conditioned responses to appetitive/aversive unconditioned stimuli. Conflict between unconditioned and conditioned stimuli occurred on the approach-aversive and avoid-appetitive trials. Results confirm the predictions and provide support for the revised RST.     

Personality traits of the behavioural approach and inhibition systems: associations with processing of emotional stimuli

This study examined the relationships of the traits associated with Gray's behavioural approach system (BAS) and behavioural inhibition system (BIS) with cognitive processing of emotional information. Initially, participants completed questionnaires covering trait impulsivity and anxiety, and BAS and BIS sensitivities. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant and neutral information. Consistent with Gray’s theory, the results showed that impulsivity and BAS sensitivity were associated with the processing of pleasant information, while anxiety and BIS sensitivity were associated with the processing of unpleasant information. These findings imply that Gray’s BAS–BIS theory can be extended to cognitive processing of emotional information.     

BIS, BAS, and bias: The role of personality and cognitive bias in social anxiety

The goal of the present research was to test the hypothesis that cognitive biases for negative and threatening social information mediate the effects of behavioral inhibition system (BIS) and behavioral approach system (BAS) sensitivity on social anxiety. Participants completed self-report measures of BIS and BAS and then underwent a social-threat induction procedure in which they were told they would have to perform a speech. A battery of cognitive bias measures was then administered, followed by a battery of state anxiety measures. Audience members also rated participants’ anxiety during the speech. Structural equation modeling was used to test the hypothesized model. As predicted, the fully-mediated model showed the best fit to the data, and higher BIS and lower BAS were found to have significant indirect effects on social anxiety via cognitive bias.     

Using Motion Tracking to Measure Avoidance in Children and Adults: Psychometric Properties,Associations With Clinical Characteristics,and Treatment-Related Change

Avoidance is implicated in many areas of psychopathology, particularly anxiety and its disorders. Accurate, reliable, valid, and objective measurement of avoidance behavior poses methodological challenges. Two key technological advances, increased computing power and the advent of motion-tracking technology, offer novel solutions to these challenges. We describe a series of three studies using a novel motion-tracking system to measure avoidance in children and adults. The first study examined behavioral avoidance of spider stimuli in large samples of children and adults (N = 200 each; the adults were the mothers of the children). Behavioral avoidance was associated with self-rated fear of spiders and increased state anxiety from before to after the task. The second study examined avoidance of threat faces in children and adults (N = 35 each; the adults were the mothers of the children) and test-retest reliability in the adults. Avoidance of threat faces was associated with broadband anxiety symptom severity. Test-retest correlations in behavioral avoidance measured 6 weeks apart was high and significant. The third study examined behavioral avoidance of spiders in clinically anxious children (N = 25) before and after cognitive-behavioral therapy for childhood anxiety disorders. Behavioral avoidance was significantly reduced following cognitive-behavioral therapy and reduction in behavioral avoidance correlated significantly with improvement in child-rated anxiety symptoms. Taken together, these studies provide strong support for the promise of motion-tracking technology to enable a new phase of behavioral avoidance research with sensitive, valid, reliable, and cost- and time-effective measurement of behavioral avoidance across the lifespan.     

Interactions between emotion regulation strategies and affective style: Implications for trait anxiety versus depressed mood

Affective style reflecting approach and inhibition is thought to be associated in distinct ways with anxious versus depressed mood; relatively few studies, however, consider how the interaction between affective style and the strategies individuals use to regulate mood and emotion might influence these associations. Sixty-seven non-disordered adults self-reported on their use of two emotion regulation strategies (cognitive reappraisal and expressive suppression), behavioral approach (BAS) and behavioral inhibition sensitivity (BIS) dimensions of affective style, and anxious and depressed mood (trait anxiety and symptoms of depression). Trait anxiety versus depressed mood was associated with unique interactive patterns of emotion regulation and affective style: enhanced use of reappraisal was linked to less depressed mood in those reporting low BAS, whereas high suppression was linked to greater trait anxiety in those reporting low BIS. The implications of findings for typical emotional processes and for clinical disorders and interventions are discussed.     

Anxiety sensitivity: the role of conscious awareness and selective attentional bias to physical threat

Selective attentional biases were examined amongst individuals varying in levels of physical anxiety sensitivity. The dot-probe paradigm was used to examine attention towards anxiety symptomatology, social threat and positive words. Stimuli were presented above (unmasked) and below (masked) the level of conscious awareness. High physical anxiety sensitivity was associated with attentional vigilance for anxiety symptomatology words in both unmasked and masked conditions. For positive words, however, those high in anxiety sensitivity were found to avoid such stimuli when they were masked, whereas they exhibited a relative vigilance when unmasked. If the differences between awareness conditions are reliable, then the impact of the automatic vigilance for threat might be modified by conscious attempts to direct attention towards other types of stimuli.     

The Role of Attachment Insecurity and Big Five Traits on Sensory Processing Sensitivity

Abstract

This study examined the interplay between behavioral inhibition/activation systems (BIS/BAS) sensitivity, attachment insecurity (i.e., anxiety and avoidance), and Big Five personality traits in predicting sensory processing sensitivity (SPS). We have specifically tested three alternative theoretical models to explain the process through which BIS/BAS sensitivity link to SPS; unique effects of attachment dimensions and personality traits, as well as moderating and mediating role of these variables. Participants (N?=?494) completed the highly sensitive Person scale, BIS/BAS scales, experiences in close relationships-revised scale, and big five inventory. The findings revealed the complex role of attachment dimensions and personality traits on SPS. Attachment avoidance, but not attachment anxiety, moderated the effect of BIS activity on SPS indicating that, compared to those with high BIS sensitivity, those with low levels of both BIS and attachment avoidance reported lower level of SPS. Attachment anxiety, neuroticism, extraversion, and openness partially mediated the effects of BIS on SPS. Conceptual implications of the findings and suggestions for future research are discussed.     

Facets of mindfulness mediate behavioral inhibition systems and emotion dysregulation

Behavioral motivation is regulated through the behavioral inhibition system (BIS) and the behavioral approach system (BAS), which underlie responses to emotional stimuli and are thought to influence emotion dysregulation. Research shows that mindfulness may increase the efficacy of emotion regulation among those with psychological symptoms, but the relationships between behavioral motivation and mindfulness have been only minimally explored. This study examines relationships between behavioral motivation systems and emotion dysregulation as mediated by mindfulness facets. Mediation was tested in a sample of 246 college students (M_age = 19.28, 61.8% female, 81.3% Caucasian) using a multiple mediator bootstrapping method. Results revealed an indirect relationship between BIS sensitivity and increased emotion dysregulation through underutilization of three distinct mindfulness skills: act with awareness, non-judging, and non-reactivity. Mindfulness facets did not mediate relationships between BAS sensitivity and emotion dysregulation, though BAS Reward Responsiveness directly predicted increased emotion dysregulation while BAS Drive was marginally associated with decreased emotion dysregulation. Findings delineate specific relationships between BIS/BAS, mindfulness skills, and emotion dysregulation while suggesting mindfulness training may be useful for BIS sensitive individuals.     

Abstract stimuli associated with threat through conditioning cannot be detected preattentively

Studies of anxiety suggest that threat stimuli can be identified preattentively, but this conclusion is questionable because of possible low-level perceptual confounds. Two experiments used visual search tasks in which abstract shapes were conditioned to carry neutral or negative valence. Experiment 1 found generally faster responses to threat-associated abstract stimuli but no evidence that they were detected preattentively, irrespective of trait anxiety level. A similar pattern was found in Experiment 2, in which individuals high in snake or spider fear showed no evidence of preattentive detection of abstract stimuli associated with their feared object. In contrast, implicit behavioral measures showed significant effects of conditioning, demonstrating that targets associated with threat were negatively evaluated in these experiments.     

Application of a behavioral theory of motivation to the concepts of anxiety and impulsivity

Gray's model has been employed in attempts to formulate theories concerning the processes underlying various types of psychopathology. In the most direct application of his model, the dominant mood is assumed to reflect the strength of the underlying motivational system—i.e., strong anxiety with a strong behavioral inhibition system (BIS), strong positive affect with a strong behavioral activation system (BAS). This approach would predict strong anxiety to be associated with a dominance of passive avoidance and extinction and, similarly, strong positive affect with a dominance of impulsivity and other approach behaviors.The present paper has argued that these expectations are based on an implicit assumption that equally stressful environments are encountered—an assumption that would be undermined by individual differences in the very motivational systems under consideration. Examination of the approach-avoidance conflict paradigm supported the argument that, at least in the case of anxiety, one should not expect a strong association between behavior and motivational states. In particular, a weak behavioral inhibition system or strong behavioral activation system is likely to facilitate anxiety-producing impulsive behavior, whereas a strong behavioral inhibition system or weak behavioral activation system may facilitate anxiety-reducing cautious behavior. Other factors were also thought to promote independence of affective states and behavioral traits across individuals.On this argument, trait anxiety conceptualized as resulting from a strong BIS may not be highly correlated with frequent anxiety. Stating this another way, the behavioral correlates of a dominant BIS may be relatively independent of a trait involving a dominance of anxious mood. Using Tellegen's (1985) discussion of self-report measures of mood and personality traits, it was proposed that the trait factor of Constraint may be more strongly associated with behavioral consequences of the BAS and BIS, whereas the Negative Emotionality dimension is largely unrelated to the behavioral effects of the BIS. Since Negative Emotionality corresponds to the traditional anxiety/neuroticism factor, this proposal differs from the customary assumptions about the alignment of Gray's motivational systems and personality traits. The personality trait of Positive Emotionality (cf. extraversion) may be associated with individual differences in the strength of the BAS, with both affective and behavioral components. Thus, the hypothesis of motivational-behavioral uncoupling offers an alternative to the usual intepretations of the three major dimensions seen in most personality inventories. Unfortunately, it remains unclear as to how well the three major personality traits (Positive Emotionality, Negative Emotionality, and Constraint) are aligned with the hypothesized underlying motivational dimensions, and any hypotheses must be seen as extremely tentative.Finally, the question of the validity of self-report measures was discussed briefly. Of greatest interest is the possibility that a subset of subjects are unable to accurately report their emotional states, and that methods are available for identifying these individuals. If so, the validity of these self-report measures may be significantly improved, facilitating research on anxiety and impulsivity.     

Reinforcement sensitivity theory and major motivational and self-regulatory processes in children

The present research explores the role of sensitivity in the BIS and the BAS as antecedents to cognitive and affective motivational processes in middle-school children. Two studies were initiated to examine the relationship between sensitivity in the behavioral inhibition system (BIS) and behavioral approach system (BAS) and several important motivational factors. The first study looked at the assumption that the BIS and the BAS are systematically linked to motives and achievement goals. The second study investigated the links between BIS/BAS and individual differences in self-regulatory processes and affect during problem-solving. The findings indicate that the motive to avoid failure, the inability to take action after failure and to initiate intended goal-directed activities, as well as the tendency to focus on avoiding misunderstanding are all grounded in threat responsiveness. Conversely, the motive to approach success, self-efficacy and the tendency to focus on comparison with others in a problem-solving setting are grounded in incentive responsiveness.

Neurocognitive assessment of emotional context sensitivity

Sensitivity to emotional context is an emerging construct for characterizing adaptive or maladaptive emotion regulation, but few measurement approaches exist. The current study combined behavioral and neurocognitive measures to assess context sensitivity in relation to self-report measures of adaptive emotional flexibility and well-being. Sixty-six adults completed an emotional go/no-go task using happy, fearful, and neutral faces as go and no-go cues, while EEG was recorded to generate event-related potentials (ERPs) reflecting attentional selection and discrimination (N170) and cognitive control (N2). Context sensitivity was measured as the degree of emotional facilitation or disruption in the go/no-go task and magnitude of ERP response to emotion cues. Participants self-reported on emotional flexibility, anxiety, and depression. Overall participants evidenced emotional context sensitivity, such that when happy faces were go stimuli, accuracy improved (greater behavioral facilitation), whereas when fearful faces were no-go stimuli, errors increased (disrupted behavioral inhibition). These indices predicted emotional flexibility and well-being: Greater behavioral facilitation following happy cues was associated with lower depression and anxiety, whereas greater disruption in behavioral inhibition following fearful cues was associated with lower flexibility. ERP indices of context sensitivity revealed additional associations: Greater N2 to fear go cues was associated with less anxiety and depression, and greater N2 and N170 to happy and fear no-go cues, respectively, were associated with greater emotional flexibility and well-being. Results suggest that pleasant and unpleasant emotions selectively enhance and disrupt components of context sensitivity, and that behavioral and ERP indices of context sensitivity predict flexibility and well-being.     

Anxiety and Attention: Is There an Attentional Bias for Positive Emotional Stimuli?

Empirical research has shown that anxiety is associated with a systematic bias in the cognitive system. Anxious individuals (clinically anxious patients and normal individuals with high-trait anxiety) are characterized by a pattern of selective processing that favors the encoding of threatening information. Is this attentional bias specific to threat-related information, or does it operate for positive emotional stimuli? The research directly connected with the existence of an attentional bias for threat in anxiety was examined.     

The role of consciousness in attentional control differences in trait anxiety

Trait anxiety has long been associated with impaired selective attention to task-irrelevant threat stimuli, both when threat is presented consciously and outside of awareness. However recent research has suggested broader deficits in selective attention, with poorer ability to ignore supraliminal non-emotional information in anxiety. Here, we investigated whether anxiety could equally be associated with poorer selective attention for non-emotional stimuli in a subliminal context. Participants performed a simple arrow discrimination task, where prior incompatible or compatible response primes were presented before targets either unmasked (supraliminal) or masked (subliminal). While distractor interference was evident in both conditions, trait anxiety was associated with increased task-irrelevant processing only in the supraliminal condition; group effects were eliminated when primes were masked. Our findings are in line with traditional accounts suggesting that differences in selective attention and cognitive control solely modulate conscious distractor processing.     

Biased attentional processing of positive stimuli in social anxiety disorder: an eye movement study

Despite the established relationship between social anxiety and attentional bias towards threat, a growing base of evidence suggests that social anxiety is additionally maintained by a deficit in the attentional processing of positive information. However, it remains unclear which component of attention is implicated in this deficit. Using eye movement-based measures and a novel attentional cuing methodology, the present study sought to investigate the presence of anxiety-linked bias in attentional engagement with, attentional disengagement from, and total fixation time to, socially relevant emotional stimuli in individuals diagnosed with social anxiety disorder, relative to non-socially anxious controls. Socially anxious individuals were found to exhibit faster attentional disengagement from positive stimuli, and reduced total fixation time to all emotional stimuli, relative to controls. Additionally for socially anxious individuals, lower total fixation times to positive stimuli were associated with higher levels of state anxiety. No differential pattern of engagement was evident between groups. We conclude that social anxiety is maintained in part by the aberrant processing of positive social stimuli.     

The time-course of threat processing in children: a temporal dissociation between selective attention and behavioral interference

Although selective attention to threatening information is an adaptive mechanism, exaggerated attention to threat may be related to anxiety disorders. However, studies examining threat processing in children have obtained mixed findings. In the present study, the time-course of attentional bias for threat and behavioral interference was analyzed in a community sample of 8-18-year-old children (N=33) using a pictorial dot probe task. Threatening and neutral stimuli were shown during 17 ms (masked), 500 ms, and 1250 ms. Results provide preliminary evidence of an automatic attentional bias for threat at 17 ms that persists during later, more controlled stages of information processing (500 and 1250 ms). Furthermore, participants showed a delayed response to threat-containing trials relative to neutral trials in the 500 and 1250 ms condition, which may indicate interference by threat. Together, these results suggest that an attentional bias for threat precedes behavioral interference in children. Furthermore, results indicate that performance in daily life can be temporarily interrupted by the processing of threatening information. In addition, results of earlier studies into selective attention in children using tasks based on behavioral responses may have been confounded by interference effects of threat. For future studies, we recommend to take behavioral interference into account.     

Reactive and self-regulatory dimensions of temperament: Interactive relations with symptoms of general distress and anhedonia

Converging evidence indicates that shared temperamental diatheses partly underlie the covariance between anxiety and depression. Although developmental psychopathology research suggests that self-regulatory temperament (e.g., effortful control or EC) mitigates reactive risks associated with negative affectivity (NA) and positive affectivity (PA), and their respective counterparts, behavioral inhibition- and activation sensitivity (BIS and BAS), no studies have established EC’s protective effects in adulthood. This study examined concurrent relations between temperament and distress symptoms shared by anxiety and depression, and anhedonic symptoms unique to depression, in young adults. Anticipated two- and three-way interactions emerged supporting EC’s moderating effect between reactive temperament (i.e., high BIS and low BAS) and both symptom dimensions. However, no interactive relations emerged between symptoms and NA, PA, and EC.     

Effect of attention control on sustained attention during induced anxiety

Anxiety has wide-reaching and complex effects on cognitive performance. Although it can intrude on cognition and interfere with performance, it can also facilitate information processing and behavioural responses. In a previous study, we showed that anxiety induced by threat of shock facilitates performance on the Sustained Attention to Response Task, a vigilance test, which probes response inhibition to infrequent nogo stimuli. The present study sought to identify factors that may have contributed to such improved performance, including on- and off-task thinking (assessed with thought probes) and individual differences in attention control, as measured with the Attention Control Scale. Replicating our prior finding, we showed that shock threat significantly reduced errors of commission on the nogo trials. However, we extended this finding in demonstrating that this effect was driven by subjects with low attention control. We therefore confirm that anxiety increases inhibitory control of prepotent responses—a mechanism which is adaptive under threat—and show that this effect is greater in those who rely more upon such prepotent responding, i.e., those with low attentional control.     

Mechanisms of visual threat detection in specific phobia

People with anxiety or stress-related disorders attend differently to threat-relevant compared with non-threat stimuli, yet the temporal mechanisms of differential allocation of attention are not well understood. We investigated two independent mechanisms of temporal processing of visual threat by comparing spider-phobic and non-fearful participants using a rapid serial visual presentation task. Consistent with prior literature, spider phobics, but not non-fearful controls, displayed threat-specific facilitated detection of spider stimuli relative to negative stimuli and neutral stimuli. Further, signal detection analyses revealed that facilitated threat detection in spider-phobic participants was driven by greater sensitivity to threat stimulus features and a trend towards a lower threshold for detecting spider stimuli. However, phobic participants did not display reliably slowed temporal disengagement from threat-relevant stimuli. These findings advance our understanding of threat feature processing that might contribute to the onset and maintenance of symptoms in specific phobia and disorders that involve visual threat information more generally.
