Reaction time is typically increased following an erroneous response. This post-error slowing is traditionally explained by a strategic adjustment of response threshold towards more conservative behaviour. A recently proposed orienting account provides an alternative explanation for post-error slowing. According to this account, committing an error evokes an orienting response (OR), which inhibits information processing in the subsequent trial, resulting in slow and inaccurate performance. We tested a straightforward prediction of the orienting account in the context of self-paced performance, adopting an individual-differences approach: Post-error slowing should be larger the less frequent an error is. To this end, participants were classified into three groups differing in overall performance accuracy. Larger post-error slowing and stronger post-error accuracy decrease were observed for the high-accuracy group than for the two other groups. Practice pronounced the post-error accuracy decline, especially for the high-accuracy group. The results are consistent with the orienting account of post-error slowing but are problematic for accounts based on strategic evaluation mechanisms.  相似文献

This study examines the relation between the error-related negativity (ERN) and post-error behavior over time in healthy young adults (N=61). Event-related brain potentials were collected during two sessions of an identical flanker task. Results indicated changes in ERN and post-error accuracy were related across task sessions, with more negative ERN associated with greater improvements in post-error accuracy. This relationship was independent of any cross-sectional relationships between overall task performance, individual difference factors, including personality and self-efficacy, and indices of self-regulatory action monitoring. These results indicate that the relation between ERN and post-error accuracy remains intact and consistent regardless of variation in this set of individual difference factors previously associated with both of these indices of self-regulatory action monitoring, providing support for the strength, robustness, and persistence of this relationship in the process of adaptively controlling behavior to enhance task performance.  相似文献

The aim of the present study was to investigate the role of driving demands, neuroticism, and their interaction when predicting driving behavior. More precisely, we strived to examine how driving behaviors (i.e., speeding, winding, tailgating and jerky driving) unfold across low and high driving demands and whether they are contingent on a personality factor that has previously been linked to stress reactivity. In a driving simulator, 50 participants with a valid driver’s license (56.6% female, age: M = 30.13, SD = 10.16) were exposed to driving scenarios of different levels of information processing and vehicle handling demands. Additionally, they filled-out a self-report questionnaire that measured their neuroticism. We found that driving behavior became safer in scenarios that were highly demanding in terms of information processing, while this pattern did not emerge with vehicle handling demands. Moreover, tentative support was found for the notion that individuals high in neuroticism are less able to adapt their behavior to higher information processing demands. The present study offers new insights on driving demands in a simulated driving context and points to the potential importance of exploring interactions between personality and situational factors when understanding driving behavior. Additionally, the results of the present study may be used to adapt driver’s education programs.  相似文献

Rats were selected on the basis of reactivity to dorsal tactile stimulation and then tested in a resident-intruder paradigm. While reactivity of residents did not influence the occurrence of agonistic behaviors or wounding of residents and intruders, reactivity of intruders did affect offensive and defensive patterns of interactions and the wounds sustained by residents and intruders. Subsequent to resident-intruder testing, rats were tested for shock-induced aggression. The pattern of the results and the results of additional experiments demonstrated that resident-intruder experience could affect subsequent shock-induced aggressive behavior.  相似文献

This experiment was designed to determine whether isolation during two developmental periods would contribute to differences in home-cage agonistic behavior and whether altered reactivity was a mediating variable. While early isolation (16–41 days) was shown to have a significant and sustained impact on agonistic behavior, isolation during a later developmental period (41–68 days) did not result in altered occurrences of agonistic behavior. While isolation did result in increased reactivity to both footshock and dorsal tactile stimuli, the pattern of these data suggested that hyperreactivity to tactile stimulation was not a satisfactory account of the increased agonistic behavior of rats raised in isolation.  相似文献

We examine the intra-individual relationships between state mood and the primary components of the individual-level criterion space (task performance, organizational citizenship behavior, and work withdrawal) as they vary within the stream of work. Using experience-sampling methods, 67 individuals in a call center responded to surveys on palmtop computers at random intervals 4–5 times each day for 3 weeks (total N = 2329). These data were matched to objective task performance obtained from organizational call records (total N = 1191). Within-persons, periods of positive mood were associated with periods of improved task performance (as evidenced by shorter call time) and engaging in work withdrawal. Trait meta-mood moderated these relationships. Specifically, individuals who attended to their moods had a stronger relationship between mood and speed of task performance (call time) and individuals able to repair their mood cognitively evidenced a weaker relationship between mood and withdrawal. Implications and the use of within-persons designs are discussed.  相似文献

The purpose of this study was to evaluate the utility of Direct Behavior Rating Single Item Scale (DBR–SIS) targets of disruptive, engaged, and respectful behavior within school-based universal screening. Participants included 31 first-, 25 fourth-, and 23 seventh-grade teachers and their 1108 students, sampled from 13 schools across three geographic locations (northeast, southeast, and midwest). Each teacher rated approximately 15 of their students across three measures, including DBR–SIS, the Behavioral and Emotional Screening System (Kamphaus & Reynolds, 2007), and the Student Risk Screening Scale (Drummond, 1994). Moderate to high bivariate correlations and area under the curve statistics supported concurrent validity and diagnostic accuracy of DBR–SIS. Receiver operating characteristic curve analyses indicated that although respectful behavior cut scores recommended for screening remained constant across grade levels, cut scores varied for disruptive behavior and academic engaged behavior. Specific cut scores for first grade included 2 or less for disruptive behavior, 7 or greater for academically engaged behavior, and 9 or greater for respectful behavior. In fourth and seventh grades, cut scores changed to 1 or less for disruptive behavior and 8 or greater for academically engaged behavior, and remained the same for respectful behavior. Findings indicated that disruptive behavior was particularly appropriate for use in screening at first grade, whereas academically engaged behavior was most appropriate at both fourth and seventh grades. Each set of cut scores was associated with acceptable sensitivity (.79–.87), specificity (.71–.82), and negative predictive power (.94–.96), but low positive predictive power (.43–.44). DBR–SIS multiple gating procedures, through which students were only considered at risk overall if they exceeded cut scores on 2 or more DBR–SIS targets, were also determined acceptable in first and seventh grades, as the use of both disruptive behavior and academically engaged behavior in defining risk yielded acceptable conditional probability indices. Overall, the current findings are consistent with previous research, yielding further support for the DBR–SIS as a universal screener. Limitations, implications for practice, and directions for future research are discussed.  相似文献

The goal of the present study was to examine emotion reactivity, a broad construct that consists of an individual’s sensitivity, intensity, and persistence of emotional reactions, as a mediator of the relationship between two types of psychopathology (depression symptoms and borderline personality disorder (BPD) symptoms) and history of self-injurious behavior (non-suicidal self-injury (NSSI) and suicide attempts (SA)). We also examined gender as a potential moderator of this relationship. Participants (N = 1914) completed measures of emotion reactivity, psychopathology, and self-injurious behavior. Results using a series of mediated path analyses indicated that emotion reactivity mediated the relationship between (1) depressive symptoms and NSSI in females only, (2) depressive symptoms and SA in females only, and (3) probable BPD diagnosis and NSSI in both genders. Emotion reactivity did not mediate the relationship between probable BPD diagnosis and SA in either gender. Our findings suggest that emotion reactivity is a possible pathway through which depression and self-injurious behavior relate, especially in women. We temper these findings, however, within the context of relatively modest observed effects.  相似文献

The purpose of this study was to investigate correlates of preterm (PT) infant’s cortisol reactivity and the association to infant negative affect, during a mother-infant interaction procedure. Participants included 48 infants born prematurely (gestational age < 37 weeks) and their mothers, assessed when infants were 12 months old corrected for prematurity. The examined variables comprised both neonatal and environmental dimensions including maternal interactive behavior. Infant negative affect and maternal interactive behavior were assessed with a standardized mother-infant interaction task. A baseline infant saliva sample was collected before the interaction began, and a second sample after the interaction episodes ended. Results revealed that decrease of infant’s cortisol concentration was significantly associated with the exposure to more sensitive, and less intrusive maternal behaviors. However, once controlled for neonatal risk, family SES and maternal psychological distress, the associations were rendered non-significant. Although the association between cortisol reactivity and negative affect trended toward significance, maternal intrusiveness was the only significant predictor of observed infant negative affect. Findings suggest the importance of primary relational experiences on PT infants' early regulatory competencies.  相似文献

Resurgence is an increase in a previously suppressed behavior resulting from a worsening in reinforcement conditions for current behavior. Resurgence is often observed following successful treatment of problem behavior with differential reinforcement when reinforcement for an alternative behavior is subsequently omitted or reduced. The efficacy of differential reinforcement has long been conceptualized in terms of quantitative models of choice between concurrent operants (i.e., the matching law). Here, we provide an overview of a novel quantitative model of resurgence called Resurgence as Choice (RaC), which suggests that resurgence results from these same basic choice processes. We review the failures of the only other quantitative model of resurgence (i.e., Behavioral Momentum Theory) and discuss its shortcomings with respect to the limited range of circumstances about which it makes predictions in applied settings. Finally, we describe how RaC overcomes these shortcomings and discuss implications of the model for promoting durable behavior change.  相似文献

The current study replicated the positive effects of performance feedback on treatment integrity and extended previous work by examining reactivity using a multiple baseline design with alternating treatments for observer-present and observer-absent conditions on teachers' implementation of a classwide behavior plan. No differences were found between conditions, and treatment integrity improved across all teachers, suggesting that performance feedback, rather than observer reactivity, was responsible for reported behavior changes.  相似文献

ObjectivesSedentary time has emerged as an independent risk factor for numerous adverse health outcomes. However, little is known about the social-cognitive correlates of sedentary behavior. The purpose of this study was to provide preliminary evidence for the factor structure and composition of sedentary derived Theory of Planned Behavior (TPB) constructs and to determine the utility of these constructs in predicting sedentary intention and sedentary time.MethodTwenty-three items were created to assess attitudes, subjective norms (SN), perceived behavioral control (PBC), and intention with respect to time spent being sedentary. Using a web-based survey, 372 adults completed a modified Sedentary Behavior Questionnaire and were then randomised to one of three TPB questionnaire packages: general, weekday, and weekend. Weekday and weekend participants completed items for work/school (less-volitional) and leisure/recreation (volitional) activities separately, resulting in five TPB models being analyzed: general, weekday work/school, weekday leisure/recreation, weekend work/school, and weekend leisure/recreation.ResultsIrrespective of model, items grouped into coherent factors consistent with TPB and explained 9–58% and 8–43% of the variance in intention and behavior, respectively. The strongest and most consistent predictor of intention and behavior were SN and intentions, respectively. Mediation analyses indicated that attitudes consistently affected sedentary time through intention.ConclusionsThere is growing evidence that the TPB is a useful framework for understanding sedentarism.  相似文献

This commentary reviews the major findings of this set of 4 papers on intergenerational continuity in antisocial behavior; it identifies strengths and remaining challenges, and discusses potential policy implications of the research. As a group, these researchers have raised the methodological bar for future work in this area, using prospective designs with multiple informants and methods to test the influences of G2 parenting and adolescent antisocial behavior in mediating continuity between G1 parenting and G3 early disruptive behavior. The pattern of findings is discussed with respect to gender of G2 and social context. The inherent challenges of conducting intergenerational research are also highlighted, within the context of offering recommendations for improving future intergenerational investigations and their feasibility.  相似文献

Researchers have generally taken a between-person, cross-sectional approach to understand why employees engage in organizational citizenship behavior (OCB). However, in light of recent work indicating that motivated behavior in organizations is often better understood using a within-person, longitudinal approach, we conceptualize citizenship performance as a dynamic cycle that varies over time. Specifically, we use self-regulation theory to explain how employees seek to fulfill goals through their OCBs, make plans to achieve those goals, engage in OCBs, and process feedback regarding their citizenship behavior. In doing so, we highlight the role played by chronic and working self-concept orientations. We also explore the way affective states influence self-regulation and citizenship, discuss unconscious or habitual acts of citizenship, and address the ways in which self-regulation and citizenship may vary over time.  相似文献

Previous studies have shown that conscientiousness facets incrementally predict performance above and beyond trait conscientiousness. In the present paper we investigate whether this finding also holds at the daily level. We conducted a ten-day experience sampling study assessing state conscientiousness in the morning and task performance and organizational citizenship behavior (OCB) in the afternoon. Using multilevel bi-factor modeling we show that general state conscientiousness positively predicts both task performance and OCB. Moreover, self-discipline and deliberation showed incremental predictive validity above and beyond overall state conscientiousness in the prediction of daily task performance, whereas none of the state conscientiousness facets uniquely predicted daily OCB levels.  相似文献

Whether explicitly acknowledged or not, behavior-analytic principles are at the heart of most, if not all, empirically supported therapies. However, the change process in psychotherapy is only now being rigorously studied. Functional analytic psychotherapy (FAP; Kohlenberg & Tsai, 1991; Tsai et al., 2009) explicitly identifies behavioral-change principles used to bring about therapeutic improvements in adult outpatients whose clinical problems stem from ineffective interpersonal repertoires. These principles include contingent responding to behavioral excesses and deficits by a therapist who has established him- or herself as a salient source of social reinforcement. Empirical support for FAP is emerging, but a variety of pragmatic and theoretical questions warrant investigation. Among the issues described in this paper are the training and dissemination of procedures for how to conduct a functional analysis, how to train therapists to identify functional stimulus classes, how to best address decreasing problem behavior without creating an aversive environment, how to enhance generalization, and how to account for the principle of equifinality when trying to specify therapeutic procedures. These and other issues stem largely from trying to disseminate a behavioral principle-based intervention rather than a topographically specified intervention. These issues present challenges and research opportunities for applied clinical behavior analysts if they wish to extend their science to address clinical issues important to the treatment of adult outpatients with normal intellectual functioning.  相似文献

The underlying mechanisms of the effectiveness of mindfulness-based interventions for emotional well-being remain poorly understood. Here, we examined the potential mediating effects of cognitive reactivity and self-compassion on symptoms of depression, anxiety and stress using data from an earlier randomised controlled school trial. A moderated time-lagged mediation model based on multilevel modelling was used to analyse the data. The findings showed that post-treatment changes in cognitive reactivity and self-coldness, an aspect of self-compassion, mediated subsequent changes in symptoms of depression, anxiety and stress. These results suggest that cognitive reactivity and self-coldness may be considered as transdiagnostic mechanisms of change of a mindfulness-based intervention programme for youth.  相似文献

This study examined the roles of fear reactivity and emotional regulatory abilities in overt and relational bullying behaviors. Survey data were collected from 124 middle school students (mean age=10.3 years, 47% males, 61% Caucasian) and their teachers in the fall and spring of a school year. Surveys included teacher- and self-rated measures of students' overt and relational bullying along with self-reported fear reactivity and effortful control. Findings show that low levels of fear reactivity and effortful control predict higher future levels of overt bullying, but not relational bullying. These results suggest that despite high correlations between overt and relational bullying, these two forms of aggression develop through different processes. The findings from this investigation are discussed with respect to their implications for theory on the development of aggression as well as prevention and intervention programming for youth aggression.  相似文献

In an analysis of the nature and origins of predictability in social behavior, two propositions are considered: (1) There exist categories of individuals whose social behavior is readily predictable from measures of personal attributes such as attitudes, traits, and dispositions as well as categories of individuals whose social behavior is readily predictable from situational and interpersonal specifications of behavioral appropriateness; (2) underlying these differences in predictability are systematic choices to enter and to spend time in social settings and interpersonal contexts that promote and facilitate one or other of these characteristic behavioral orientations. The implications of these propositions for the study of personality and social behavior are considered in the specific case of the psychological construct of self-monitoring and in the general case of understanding the reciprocal influences of individuals and their social worlds.  相似文献
