One of the most consistent findings in the criminological literature is that African American males are arrested, convicted, and incarcerated at rates that far exceed those of any other racial or ethnic group. This racial disparity is frequently interpreted as evidence that the criminal justice system is racist and biased against African American males. Much of the existing literature purportedly supporting this interpretation, however, fails to estimate properly specified statistical models that control for a range of individual-level factors. The current study was designed to address this shortcoming by analyzing a sample of African American and White males drawn from the National Longitudinal Study of Adolescent Health (Add Health). Analysis of these data revealed that African American males are significantly more likely to be arrested and incarcerated when compared to White males. This racial disparity, however, was completely accounted for after including covariates for self-reported lifetime violence and IQ. Implications of this study are discussed and avenues for future research are offered.  相似文献

The goal of affirmative action policies is to empower formerly disenfranchised groups. But what if the procedures used to implement these policies activate a set of social psychological processes that prevent the occurrence of productive social interactions between target-group and non-target-group members? With that question in mind, a conceptual model is developed which focuses on the potential effects of affirmative action procedures on social interactions between members of policy target and nontarget groups. To conceptualize these potential effects of procedures, the concept of a policy schema is introduced. Special attention is paid to the conditions under which beliefs about procedures contained in policy schemas will influence patterns of interactions between target-group and non-target-group members. With that as background, a call is made for more complete analyses of the social psychology of affirmative action.  相似文献

Behavioral skills training (BST) has been employed within many different populations for the reduction of problem behaviors and acquisition of new skills; however, these changes have not always maintained over time. This study evaluated the effects of a booster training for re-establishing the classroom management proficiencies that teachers had acquired previously, but had declined over a 12-month period. The single-subject experimental results showed the booster training to be effective in re-establishing teacher performance of skills as measured by both analogue role-play and in situ postassessments within the classroom. These findings suggest that a booster training utilizing BST may be an important strategy for maintaining skill performance over time.  相似文献

We describe and examine three changes (personnel, process, and structure) that self-managed teams can make to remedy performance problems. We also discuss why self-managed teams may over-emphasize process and (to a lesser extent) personnel changes over structural changes. Furthermore, we describe and test two specific diagnostic feedback interventions aimed at helping teams make functional structural change. Seventy-eight 4-person teams of undergraduate students participated in two trials of a networked laboratory simulation task. All teams were initially structurally misaligned and subsequently received (a) no feedback, (b) one type of feedback only, or (c) both types of feedback. Results confirmed that structurally misaligned teams demonstrated dysfunctional change by changing process more frequently than structure, with detrimental effects for subsequent performance. When teams received the feedback interventions, however, they were more likely to change their structure and thereby improve their performance.  相似文献

Retrospective analysis of definitions published over some 35 years suggests the major subject areas of the field can be summed up in three themes: beyond-ego psychology, integrative/holistic psychology, and psychology of transformation. Theme frequency analysis reveals that early emphasis on alternative states of consciousness has moderated into a broader approach to human transcendence, wholeness, and transformation. This expanded definition of transpersonal psychology suggests the field has much in common with integral psychology. As a comprehensive, historically based content summary, this tripartite definition contributes a small but vital piece to the foundation of a transpersonal vision that is spreading across the globe. While transpersonal psychology still needs to embody the inclusiveness and diversity that it represents, its vision is one of great relevance to the contemporary human condition.  相似文献

Research on the effect of paternal mental health problems, particularly on young children, is based predominantly on clinical levels of depression. Furthermore, potential mediators such as marital discord have often been overlooked. This longitudinal community study assessed the association between paternal mental health symptoms in a community sample (N = 705) assessed at 3 months postnatally (Edinburgh Postnatal Depression Scale) and 36 months (General Health Questionnaire) and children's socio‐emotional and behavioural problems at 51 months (Strengths and Difficulties Questionnaire) as reported by mother, father and teacher. Controlling for socioeconomic status and maternal mental health symptoms at 3 and 36 months, paternal postnatal depressive symptoms predicted more father‐reported child problems at 51 months but, in contrast to previous findings, not mother‐reported problems. Paternal mental health symptoms at 36 months predicted both maternal and paternal reports of child problems at 51 months controlling for both paternal and maternal postnatal symptoms. Paternal mental health symptoms at 3 and 36 months were not significant predictors of teacher‐reported child problems. Postnatal marital discord and paternal mental health problems at 36 months both mediated the relationship between paternal postnatal symptoms and later child emotional and behavioural problems. Child gender did not moderate the relationship. Implications for interventions are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

伤害回避是指个体对厌恶刺激信号做出强烈的反应,并学会被动地回避惩罚的一种倾向,这一倾向使得个体反复思考未来的结局,并谨慎小心地对待不确定情景中的事件,进而更有可能诱发情感障碍。伤害回避涉及的神经网络包括三个子网络,即额顶叶-前扣带皮层的连接、皮层-杏仁核的连接和白质通道的结构性连接,这三个子网络分别与羞怯感-易疲劳性、预期担心以及不确定环境中的害怕情绪有关。而其生物基础则包括单一基因多态性和基因多态间的交互作用。今后的研究应该集中在深化伤害回避神经网络与生物基础间的联合机制、研究三种及以上基因多态间的交互作用、考察其他因素对基因效应的调节作用、注重伤害回避四种亚型相关神经网络之间的连接、探讨5-HT4等其他几种5-羟色胺受体多态性与伤害回避的关系以及分析伤害回避内部机制在抗抑郁治疗中的作用等方面。  相似文献

ABSTRACT

Research in older Caucasians has demonstrated that cognitive activity is related to cognitive function in late adulthood. Knowledge of this association is limited in older minority populations. We examined the relation of cognitive activity and access to cognitive resources, with cognitive function in a group of 108 older African Americans. We constructed two scales to measure the frequency of cognitive activity and the presence of resources that promote cognitive activity during early and late life. Both measures had high internal consistency and the cognitive activity scale had adequate temporal stability over a 4-week interval. In analyses that controlled for age and education, more frequent lifetime cognitive activity was related to current cognitive function, but lifetime cognitive resources only approached significance. The results suggest that both measures are psychometrically sound in a minority population and that lifetime cognitive activity may contribute to current cognitive function in African Americans.  相似文献

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明:(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用:在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。  相似文献

The miracle argument for scientific realism can be cast in two forms: according to the miraculous theory argument, realism is the only position which does not make the empirical successes of particular theories miraculous. According to the miraculous choice argument, realism is the only position which does not render the fact that empirically successful theories have been chosen a miracle. A vast literature discusses the miraculous theory argument, but the miraculous choice argument has been unjustifiably neglected. I raise two objections to Richard Boyd's defense of the latter: (1) we have no miracle free account of the emergence of take-off theories and (2) the anti-realist can account for the non-miraculous choice of empirically successful theories by attributing mere empirical adequacy to background theory. I argue that the availability of extra-empirical criteria that are arguably truth conductive but not theory-laden suffices to answer (1), and the unavailability of extra-empirical criteria that are conductive to empirical adequacy but not necessarily to truth (and are also not theory-laden) constitutes to reply to (2). The prospects for a realist victory are at least somewhat promising, on a controversial assumption about the rate at which empirically successful theories emerge.  相似文献
