Unpleasant stimuli differentially modulate inhibitory processes in an emotional Go/NoGo task: an event-related potential study

Threat stimuli typically elicit a psychophysiological response pattern supporting the organism's preparation for active defence. Differently, blood stimuli prompt a distinctive autonomic response pattern and sustained processing, which do not call for clear-cut mobilisation for action. However, the contribution of motor disposition in these response patterns remains unclear. One way to address this issue is to investigate whether threat and blood stimuli differentially affect the active suppression of an ongoing motor activity. Thirty-two undergraduates were presented with threat, mutilation, pleasant, and neutral pictures in an emotional Go/NoGo task. The amplitudes of the NoGo-N2 and NoGo-P3 components of the event-related potentials were analysed as indices of conflict monitoring and inhibition of motor response, respectively. Reaction times to Go trials were significantly faster for threat than for mutilations. The NoGo-N2 was significantly larger to threat than to mutilations, whereas the NoGo-P3amplitude did not differ between the two conditions. These findings suggest that threat stimuli facilitated the execution of a prepotent response and enhanced conflict monitoring when action must be withheld. In contrast, blood stimuli did not either promote action in the Go trials or increase conflict in the NoGo condition, suggesting a response pattern compatible with defensive immobility.     

Expertise in the Game of Go and Levels of Visuospatial and Pattern Recognition Abilities

The results of existing research indicate higher levels of visuospatial and pattern recognition abilities in experts in the game of Go compared to novices. However, the tasks included in the research have been focused only on Go‐game situations. This study aimed to verify the hypothesis that experts in the game of Go would achieve higher scores, compared to novices, on behavioral tests measuring visuospatial abilities and that pattern recognition tests would be a predictor of group membership (experts, low‐skill players, novices). We consider that the game of Go can be treated as a special case of tasks related to visuospatial abilities and pattern recognition. Sixty men participated in the study, including 17 experts in the game of Go, 13 low‐skill players, and 30 novices. The results of behavioral tests—the advanced version of Raven's Progressive Matrices and the APIS‐Z Test's Visuospatial Abilities subscale, which measure pattern recognition and visuospatial abilities, respectively—confirmed the hypotheses.     

Emotions in Go/NoGo conflicts

On the basis of current emotion theories and functional and neurophysiological ties between the processing of conflicts and errors on the one hand and errors and emotions on the other hand we predicted that conflicts between prepotent Go responses and occasional NoGo trials in the Go/NoGo task would induce emotions. Skin conductance responses (SCRs), corrugator muscle activity, and startle blink responses were measured in three experiments requiring speeded Go responses intermixed with NoGo trials of different relative probability and in a choice reaction experiment serving as a control. NoGo trials affected several of these emotion-sensitive indicators as SCRs and startle blinks were reduced whereas corrugator activity was prolonged as compared to Go trials. From the pattern of findings we suggest that NoGo conflicts are not aversive. Instead, they appear to be appraised as obstructive for the response goal and as less action relevant than Go trials.     

Assessing inattention and impulsivity in children during the Go/NoGo task

Behavioural performance in the Go/NoGo task was compared with caregiver and teacher reports of inattention and hyperactivity‐impulsivity in 1,151 children (N=557 boys; N=594 girls) age 9–10 years old. Errors of commission (NoGo errors) were significantly correlated with symptom counts of hyperactivity‐impulsivity, while errors of omission (Go errors) were significantly correlated with symptom counts for inattention in both caregiver and teacher reports. Cross‐correlations were also evident, however, such that errors of commission were related to inattention symptoms, and errors of omission were related to hyperactivity‐impulsivity. Moreover, hyperactivity‐impulsivity and inattention symptoms were highly intercorrelated in both caregiver (r=.52) and teacher reports (r=.70), while errors of commission and omission were virtually uncorrelated in the Go/NoGo task (r=.06). The results highlight the difficulty in disentangling hyperactivity‐impulsivity and inattention in questionnaires, and suggest that these constructs may be more clearly distinguished in laboratory measures such as the Go/NoGo task.     

Wives' and Husbands' Cortisol Reactivity to Proximal and Distal Dimensions of Couple Conflict

Poor marital quality has been linked repeatedly to spouses' health problems, with alterations to physiological stress response systems, such as the hypothalamic‐pituitary‐adrenocortical (HPA) axis, as one putative mechanism. This study assessed wives' and husbands' HPA axis (i.e., cortisol) reactivity to marital criticism during laboratory‐based conflict discussions, in the context of marital aggression experienced during the previous year. Ninety‐five couples provided one saliva sample prior to—and three samples following—a triadic family conflict discussion involving their teenage child. Marital criticism during the conflict discussion was related to heightened HPA reactivity for husbands only. For wives, an interaction emerged between criticism during the conflict and previous‐year marital aggression: only those wives who had experienced high levels of marital aggression demonstrated a positive association between criticism and cortisol output. Husbands thus appeared to be more physiologically reactive to the in‐the‐moment critical behaviors, whereas wives' responses to proximal conflict were related to previous and perhaps more chronic experiences of marital aggression. These findings shed light on ways in which within‐couple processes during family conflicts involving children contribute to individual physiological functioning, enhancing our understanding of the role of family relationships in physical health outcomes.     

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.     

Testing an Adaptationist Theory of Trait Covariation: Relative Bargaining Power as a Common Calibrator of an Interpersonal Syndrome

This article provides the first test of an adaptationist ‘common calibration’ theory to explain the origins of trait covariation, which holds that (i) personality traits are often facultatively calibrated in response to cues that ancestrally predicted the reproductive payoffs of different trait levels and (ii) distinct traits that are calibrated on the basis of common input cues will exhibit consistent patterns of covariation. This theory is applied to explain the covariation within a ‘personality syndrome’ encompassing various interpersonal trait dimensions (e.g. extraversion, emotionality and attachment styles). Specifically, it is hypothesized that these traits are inter‐correlated because each is calibrated in response to relative bargaining power (RBP)—a joint function of one's ability to benefit others and harm others. Path analyses from a correlational study compellingly supported this theoretical model: Objective and self‐perceived measures of RBP‐enhancing phenotypic features (physical attractiveness and physical strength) influenced an internal regulatory variable indexing RBP (i.e. self‐perceived RBP), which in turn had robust effects on each of the focal personality traits. Moreover, in support of the theory's core postulate, controlling for self‐perceived RBP greatly reduced the covariation within the interpersonal syndrome. These novel findings illustrate the promise of an evolutionary psychological approach to elucidating trait covariation. Copyright © 2013 John Wiley & Sons, Ltd.     

Psychometric Evaluation and Revision of Carver and White's BIS/BAS Scales in a Diverse Sample of Young Adults

The psychometric properties of the Behavioral Inhibition System and Behavioral Activation System (BIS/BAS) scales (Carver & White, 1994) were evaluated in a large, racially diverse sample of undergraduate students. Findings from this study indicate that the BIS/BAS scales work differently (i.e., are multidimensional and lack configural invariance) when assessing BIS and BAS in a diverse sample. Numerous model modifications were needed to obtain adequate fitting models for the total sample and individual racial groups. The findings suggest that this is due to items that assess multiple constructs differently across self-reported race categories. As part of this research, a revised version of the BIS/BAS scales was constructed that appears to be invariant across self-reported race category and simultaneously addresses the other psychometric concerns associated with the original scale. Caution should be used when applying the BIS/BAS scales as originally specified to assess behavioral inhibition and activation in a racially diverse sample. Researchers might want to use this revised version of the scale as an alternative.     

Event‐related potential differences in children supplemented with long‐chain polyunsaturated fatty acids during infancy

Long‐chain polyunsaturated fatty acids (LCPUFA) have been shown to be necessary for early retinal and brain development, but long‐term cognitive benefits of LCPUFA in infancy have not been definitively established. The present study sought to determine whether LCPUFA supplementation during the first year of life would result in group differences in behavior and event‐related potentials (ERPs) while performing a task requiring response inhibition (Go/No‐Go) at 5.5 years of age. As newborns, 69 children were randomly assigned to infant formulas containing either no LCPUFA (control) or formula with 0.64% of total fatty acids as arachidonic acid (ARA; 20:4n6) and various concentrations of docosahexaenoic acid (DHA; 22:6n3) (0.32%, 0.64% or 0.96%) for the first 12 months of life. At 5.5 years of age, a task designed to test the ability to inhibit a prepotent response (Go/No‐Go) was administered, yielding both event‐related potentials (ERPs) and behavioral data. Behavioral measures did not differ between groups, although reaction times of supplemented children were marginally faster. Unsupplemented children had lower P2 amplitude than supplemented children to both Go and No‐Go conditions. N2 amplitude was significantly higher on No‐Go trials than Go trials, but only for supplemented children, resulting in a significant Group × Condition interaction. Topographical analysis of the ERPs revealed that the LCPUFA‐supplemented group developed a novel period of synchronous activation (microstate) involving wider anterior brain activation around 200 ms; this microstate was not present in controls. These findings suggest that LCPUFA supplementation during the first 12 months of life exerts a developmental programming effect that is manifest in brain electrophysiology.

Construct validity and generalizability of the Carver–White behavioural inhibition system/behavioural activation system scales

The factorial structure and invariance of the BIS/BAS scales of Carver and White were assessed across three samples from the USA, UK, and Italy. Previous validation studies of the BIS/BAS scales relied on individual samples drawn from English‐speaking populations only and failed to formally assess generalizability. The current study shows that the four‐factor structure proposed by Carver and White—i.e. one BIS and three BAS facets—achieved satisfactory psychometric properties in all three samples and that measurement invariance was obtained across countries. Latent mean differences due to gender and country were also investigated. Theoretical issues concerning the validity of the BIS/BAS scales are addressed.

Revised Reinforcement Sensitivity Theory and Laboratory Assessment of BIS and BAS in Children

There is considerable interest in Gray’s reinforcement sensitivity theory. However, few measures of the behavioral approach (BAS) and inhibition systems (BIS) exist for children. Moreover, the theory was substantially revised a decade ago and measurement instruments are still largely based on the old theory. Our aim was to revise questionnaire and laboratory assessments of BIS and BAS for children. Performance on the Point Scoring Reaction Time Task for Children-Revised (PSRTT-CR) conformed to theoretical expectations. Caregiver reports of BIS and BAS were associated with corresponding PSRTT-CR indices, suggesting cross-method convergent and discriminant validity. There was convergence with physiological correlates of BAS, but not physiological correlates of BIS. Overall, our revised measures represent promising instruments of children’s BIS and BAS.

采用ERP技术研究13例正常青年人在声音诱发的不同情绪条件下,对反应抑制加工过程的影响,并试图阐明其潜在脑机制。实验中选择正、中、负三种声音各50种,作为诱发情绪的刺激材料。结果发现Go条件下的反应时在负性、中性、正性条件下依次减短;Go与Nogo刺激均诱发出显著的N1成分,中性条件下波幅显著大于正负性情绪条件。此外,三种情绪背景下, Nogo刺激诱发出显著的N2与P3成分。Nogo-N2主要分布在头皮前中部,在Fz点波幅最大。Nogo-P3主要分布在头皮中部,Pz点波幅最大。中性条件下Nogo-N2波幅显著大于负性与正性条件,而正性和负性之间差异不显著。行为结果表明,听觉负性情绪诱发对反应执行有干扰作用;ERP结果表明声音诱发的情绪对早期听觉选择性注意具有调节作用。听觉情绪诱发对反应抑制加工过程有显著影响,且该影响在早期反应冲突监控阶段最为明显。     

Previous reward decreases errors of commission on later ‘No‐Go’ trials in children 4 to 12 years of age: evidence for a context monitoring account

Inhibitory control is widely hypothesized to be the cornerstone of executive function in childhood and the central deficit in a number of developmental disorders, including attention‐deficit/hyperactivity disorder (ADHD). However, recent evidence from adults indicates that performance on response inhibition tasks may primarily reflect non‐inhibitory attentional control (context monitoring) processes. Yet it may be that inhibition plays a more central role in childhood – a time when the architecture of cognitive processes might be more transparent due to wide variability in skill level. Here we directly test inhibitory and context monitoring explanations of task performance on a Go/No‐Go task in a large group of children 4–12 years of age. We conclude that traditional inhibitory conceptualizations of task performance on the Go/No‐Go task cannot account for our findings, calling into question evidence supporting a central role for inhibitory control in cognitive development or developmental psychopathology.     

Executive cognitive functioning and aggression: Is it an issue of impulsivity?

A large body of research has documented a relation between the executive cognitive functions (ECFs) and interpersonal aggressive behavior. A predominant theory proposes that individuals with poor ECFs are more aggressive because they are unable to inhibit impulsive behaviors. However, evidence for this relationship is typically indirect. In this study, 46 healthy men and women completed measures of ECF, the Taylor Aggression Paradigm, and the Go/No‐Go discrimination task, a behavioral measure of impulsivity. Also, impulsiveness of participant responses during the aggression task was directly assessed by measuring latency of responses to provocation (“set‐time”). It was hypothesized that low‐quartile–scoring ECF men and women would perform more aggressively and more impulsively than high‐quartile peers. Consistent with expectations, results indicated that ECF was related to aggression and to impulsivity on the Go/No‐Go task. However, low‐ECF men and women did not have shorter set‐times; in fact, on this task, low‐ECF participants' behavioral decisions seemed slightly slower than those of high‐ECF participants. In light of these results, the authors speculate that a social information‐processing problem may mediate the ECF aggression relationship rather than altered impulsivity per se. Aggr.

On Disjunctive Rights

This article examines the idea of disjunctive rights—an idea first suggested by Joel Feinberg and more recently advocated by Richard Arneson. Using a hypothetical scenario to bring forward a conflict between two rights that cannot be simultaneously fulfilled, the suggestion that the conflict can be solved by describing the right‐holders as holding disjunctive rights—rights that involve, in a significant way, a disjunction—is scrutinized. Several interpretations of the idea of disjunctive rights are examined from the perspectives of the interest theory and will theory of rights. Ultimately, the idea of disjunctive rights fails to provide an acceptable solution to the problem at hand, as each interpretation has unacceptable implications. This conclusion challenges the compossibilist thesis, according to which moral rights do not, ultimately, conflict. Alternatively, if one wishes to keep the possibility of compossibility and disjunctive rights, the mainstream theories of rights must be revised or rejected.     

Delayed N2 response in Go condition in a visual Go/Nogo ERP study in children who stutter

Purpose of the studyThe main aim of the study was to investigate the attentional and inhibitory abilities and their underlying processes of children who stutter by using behavioural measurement and event-related potentials (ERP) in a visual Go/Nogo paradigm.MethodsParticipants were 11 children who stutter (CWS; mean age 8.1, age range 6.3–9.5 years) and 19 typically developed children (TDC; mean age 8.1, age range 5.8–9.6 years). They performed a visual Go/Nogo task with simultaneous EEG recording to obtain ERP responses.ResultsResults showed that CWS had longer N2 and P3 latencies in the Go condition compared to the TDC. In contrast, the groups did not differ significantly in the Nogo condition or behavioural measures.ConclusionsOur findings did not confirm less efficient inhibitory control in CWS but suggest atypical attentional processing such as stimulus evaluation and response selection.Educational Objectives: The reader will be able to (a) describe recent findings on attention and inhibitory control in children who stutter, (b) describe the measurement of attentional processing, including inhibitory control, and (c) describe the findings on attentional processing in children who stutter as indexed by the event-related potentials in a visual Go/Nogo paradigm.     

Brain and behavioral inhibitory control of kindergartners facing negative emotions

Inhibitory control (IC) – one of the most critical functions underlying a child's ability to self‐regulate – develops significantly throughout the kindergarten years. Experiencing negative emotions imposes challenges on executive functioning and may specifically affect IC. In this study, we examined kindergartners' IC and its related brain activity during a negative emotional situation: 58 children (aged 5.5–6.5 years) performed an emotion‐induction Go/NoGo task. During this task, we recorded children's performance and brain activity, focusing on the fronto‐central N2 component in the event‐related potential (ERP) and the power of its underlying theta frequency. Compared to Go trials, inhibition of NoGo trials was associated with larger N2 amplitudes and theta power. The negative emotional experience resulted in better IC performance and, at the brain level, in larger theta power. Source localization of this effect showed that the brain activity related to IC during the negative emotional experience was principally generated in the posterior frontal regions. Furthermore, the band power measure was found to be a more sensitive index for children's inhibitory processes than N2 amplitudes. This is the first study to focus on kindergartners' IC while manipulating their emotional experience to induce negative emotions. Our findings suggest that a kindergartner's experience of negative emotion can result in improved IC and increases in associated aspects of brain activity. Our results also suggest the utility of time‐frequency analyses in the study of brain processes associated with response inhibition in young children.     

Intergroup conflict and barriers to common ground: A self‐affirmation perspective

Psychological barriers to conflict resolution stem, in part, from defensive responses to feelings of self‐threat. Self‐affirmation theory proposes that affirmations of global self‐worth—often achieved by writing or reflecting on core values—can broaden individuals' perspectives and potentially reduce biases in their intergroup judgments. In this paper, we review the extant literature on the use of self‐affirmation to potentially reduce intergroup biases in order to shed light on the role of self‐threat in perpetuating conflict. Self‐affirmation has been shown to impact 3 key aspects of intergroup conflict: (a) the strength with which conflict‐supporting beliefs are held, (b) the biased processing of conflict‐relevant information, and (c) the resistance to seeing common ground in negotiations. Discussion centers on the limits as well as the potential of self‐affirmation to promote openness and conflict resolution.     

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.     

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.
