In a community-dwelling sample (N = 4,790; age range 14-94), we examined whether personality traits prospectively predicted performance on a verbal fluency task. Open, extraverted, and emotionally stable participants had better verbal fluency. At the facet level, dispositionally happy and self-disciplined participants retrieved more words; those prone to anxiety and depression and those who were deliberative retrieved fewer words. Education moderated the association between conscientiousness and fluency such that participants with lower education performed better on the fluency task if they were also conscientious. Age was not a moderator at the domain level, indicating that the personality-fluency associations were consistent across the life span. A disposition toward emotional vulnerability and being less open, less happy, and undisciplined may be detrimental to cognitive performance. 相似文献

Recent studies have highlighted the impact of deployment on military families and children and the corresponding need for interventions to support them. Historically, however, little emphasis has been placed on family-based interventions in general, and parenting interventions in particular, with returning service members. This paper provides an overview of research on the associations between combat deployment, parental adjustment of service members and spouses, parenting impairments, and children's adjustment problems, and provides a social interaction learning framework for research and practice to support parenting among military families affected by a parent's deployment. We then describe the Parent Management Training-Oregon model (PMTO(?)), a family of interventions that improves parenting practices and child adjustment in highly stressed families, and briefly present work on an adaptation of PMTO for use in military families (After Deployment: Adaptive Parenting Tools, or ADAPT). The article concludes with PMTO-based recommendations for clinicians providing parenting support to military families. 相似文献

The paper deals with the issue of practical knowledge for enabling participation. Participation as a strategy for change is widespread in community, health and human service contexts. Research to date has focused on the mechanisms of beneficiaries' participation (e.g. identity, empowerment, activity, gender, space). However, participation as an engagement strategy is action oriented and requires high levels of interaction between those creating the conditions for participation and those participating. These conditions need to be continuously adjusted and outcomes are often unpredictable. This process of ‘working with’ is often dealt with as a technical issue and captured in metaphorical language. Less emphasis has been given to the type of knowledge modalities that might be necessary in order to enable participation. Drawing on an ethnographic case study of participation in a youth inclusion programme the paper explores the role of stories as potential indicators of practical knowledge. The paper argues that enabling young people's participation requires intuition and imagination, patience and perseverance, and judgement for acting under uncertainty. It concludes that stories only partially fulfil their potential as indicators of such knowledge modalities. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed. 相似文献

Statistical properties in the visual environment can be used to improve performance on visual working memory (VWM) tasks. The current study examined the ability to incidentally learn that a change is more likely to occur to a particular feature dimension (shape, color, or location) and use this information to improve change detection performance for that dimension (the change probability effect). Participants completed a change detection task in which one change type was more probable than others. Change probability effects were found for color and shape changes, but not location changes, and intentional strategies did not improve the effect. Furthermore, the change probability effect developed and adapted to new probability information quickly. Finally, in some conditions, an improvement in change detection performance for a probable change led to an impairment in change detection for improbable changes. 相似文献

The immediate-early gene early growth response gene-1 (EGR-1, zif-268) has been extensively studied in synaptic plasticity and memory formation in a variety of memory systems. However, a convincing role for EGR-1 in amygdala-dependent memory consolidation processes has yet to emerge. In the present study, we have examined the role of EGR-1 in the consolidation and reconsolidation of amygdala-dependent auditory Pavlovian fear conditioning. In our first series of experiments, we show that EGR-1 is regulated following auditory fear conditioning in the lateral nucleus of the amygdala (LA). Next, we use antisense oligodeoxynucleotide (ODN) knockdown of EGR-1 in the LA to show that training-induced expression of EGR-1 is required for memory consolidation of auditory fear conditioning; that is, long-term memory (LTM) is significantly impaired while acquisition and short-term memory (STM) are intact. In a second set of experiments, we show that EGR-1 is regulated in the LA by retrieval of an auditory fear memory. We then show that retrieval-induced expression of EGR-1 in the LA is required for memory reconsolidation of auditory fear conditioning; that is, post-retrieval (PR)-LTM is significantly impaired while memory retrieval and PR-STM are intact. Additional experiments show these effects to be restricted to the LA, to be temporally graded, and unlikely to be due to nonspecific toxicity within the LA. Collectively, our findings strongly implicate a role for EGR-1 in both the initial consolidation and in the reconsolidation of auditory fear memories in the LA. 相似文献

We report an experiment that examined whether children with Autistic Spectrum Disorder (ASD) spontaneously converge, or align, syntactic structure with a conversational partner. Children with ASD were more likely to produce a passive structure to describe a picture after hearing their interlocutor use a passive structure to describe an unrelated picture when playing a card game. Furthermore, they converged syntactic structure with their interlocutor to the same extent as did both chronological and verbal age-matched controls. These results suggest that the linguistic impairment that is characteristic of children with ASD, and in particular their difficulty with interactive language usage, cannot be explained in terms of a general deficit in linguistic imitation. 相似文献

We examined the effect of cognitive fatigue on the Attention Networks Test (ANT). Participants were 228 non-demented older adults. Cognitive fatigue was operationally defined as decline in alerting, orienting, and executive attention performance over the course of the ANT. Anchored in a theoretical model implicating the frontal basal ganglia circuitry as the core substrate of fatigue, we hypothesized that cognitive fatigue would be observed only in executive attention. Consistent with our prediction, significant cognitive fatigue effect was observed in executive attention but not in alerting or orienting. In contrast, orienting improved over the course of the ANT and alerting showed a trend, though insignificant, that was consistent with learning. Cognitive fatigue is conceptualized as an executive failure to maintain and optimize performance over acute but sustained cognitive effort resulting in performance that is lower and more variable than the individual's optimal ability. 相似文献

Previous research has shown that sounds facilitate perception of visual patterns appearing immediately after the sound but
impair perception of patterns appearing after some delay. Here we examined the spatial gradient of the fast crossmodal facilitation
effect and the slow inhibition effect in order to test whether they reflect separate mechanisms. We found that crossmodal
facilitation is only observed at visual field locations overlapping with the sound, whereas crossmodal inhibition affects
the whole hemifield. Furthermore, we tested whether multisensory perceptual learning with misaligned audio-visual stimuli
reshapes crossmodal facilitation and inhibition. We found that training shifts crossmodal facilitation towards the trained
location without changing its range. By contrast, training narrows the range of inhibition without shifting its position.
Our results suggest that crossmodal facilitation and inhibition reflect separate mechanisms that can both be reshaped by multisensory
experience even in adult humans. Multisensory links seem to be more plastic than previously thought. 相似文献

This study examined predictors of employee perceptions of organizational work–life support. Using organizational support theory and conservation of resources theory, we reasoned that workplace demands and resources shape employees' perceptions of work–life support through two mechanisms: signaling that the organization cares about their work–life balance and helping them develop and conserve resources needed to meet work and nonwork responsibilities. Consistent with our hypotheses, we found that higher demands (work hours and work overload) were associated with reduced perceptions that the organization was supportive of work–life integration. Resources (job security, fit between employees' needs and the flexible work options available to them, supervisor support and work group support) were positively associated with perceptions of organizational work–life support. The results of this study urge further scholarly attention to work-based demands and resources as predictors of perceived organizational work–life support and yield implications for managerial practice. 相似文献
