COMT基因对注意控制神经基础的调控效应：影像遗传学研究的元分析

为探索注意控制能力个体差异的遗传来源, 当前研究主要关注儿茶酚胺氧位甲基转移酶(catechol-O-Methyltransferase, COMT)基因对参与注意控制加工的前额叶脑区的调控作用。为进一步回答COMT基因是否也对全脑范围的注意脑区具有调控作用, 本文对17篇遗传影像学研究进行元分析。结果发现, COMT基因Val/Val (vv)基因型的被试在注意控制任务下, 不仅前额叶脑区的激活水平高于Met/Met(mm)基因型的被试, 在前扣带回和后扣带回等前额叶之外的脑区激活水平也高于mm基因型的被试, 而且在这些脑区的效应值(vv>mm)都较大(Cohen’s d > 0.8)。由此, 元分析结果表明：COMT基因不仅调控前额叶脑区, 而且对形成注意控制网络的多个脑区都有调控效应。此结果提示注意控制能力的个体差异可能部分的来自于COMT基因对注意控制网络的调控作用。     

‘Thank God I’m not a Jungian’

This article focuses less on the content of Jung's ideas than on ways in which they act as both invitation and challenge to engage with psyche. It explores the mythic framework of Jung's approach and how this can enable individuals to live in psychological and mundane worlds in which there can be no final certainties. It elaborates three particular aspects of Jung's thinking that I have found personally valuable: his generosity of vision, his insistence that individuals engage for and with themselves rather than relying on someone else's ideas, and his ponderings on the relationship between the individual and the collective. All three aspects seem to be important elements of the work of individuation.     

Personality Certainty and Politics: Increasing the Predictive Utility of Individual‐Difference Inventories

Research on political psychology has benefitted from using individual‐difference measures to predict political attitudes and behavior. And, previous research has further identified a number of specific variables that enhance the predictive utility of individual‐difference scales. However, a potentially important factor that has been overlooked is the certainty with which people make their responses. The present research establishes that the certainty with which people respond to scales is associated with stability of the scale responses over time and correspondence between the scale and related outcomes. In addition, the effects of certainty in political ideological identification in predicting politically relevant outcomes hold when controlling for a number of previously established moderators. This research suggests that measuring certainty in answers to individual‐difference scales can be a useful and efficient way to increase the predictive utility of those scales within the political domain and beyond. This benefit is demonstrated with need for cognition (Study 1), need to evaluate (Study 2), and ideological identification (Studies 2 and 3).     

不确定性容忍度对跨期选择的影响及其情景依赖性

采用2(不确定性容忍度：高、低)×2(跨期日期：今天/14天、今天/180天)×2(延迟奖赏值：200元、1000元)混合实验设计,探讨不同任务特征下不确定性容忍度对跨期选择的影响。结果表明：跨期日期为180天时,不确定性容忍度主效应边缘显著;不确定性容忍度与延迟奖赏值交互作用显著：在200元时低容忍度个体对延迟奖赏的折扣程度大于高容忍度个体,在1000元时无此效应;跨期日期为14天时,不确定性容忍度的主效应及其与延迟奖赏值交互作用均不显著。这表明,不确定性容忍度对跨期选择存在影响,但这种影响受到跨期日期和延迟奖赏值的调节,具有情景依赖性。     

麦金太尔论社会关系、共同利益与个人利益

我们从出生到死亡都处在一种接受与给予的关系中 ,我们从谁那里接受和给予谁往往是不对称的。这是我们参与到这个网络中不得不懂得的。在这个接受与给予的关系中 ,有我们的共同利益和我们个人的利益。同时 ,处在这样一种关系中 ,也需要我们遵守相应的德性规则。     

工作重塑：获得意义性工作与个人成长的新途径

工作重塑是组织行为学中新近出现的一个热点话题,是指员工通过自己对工作进行重新建构来形塑自己的工作认同以及工作角色,其核心目的就是员工对他们的工作进行再设计以获得较高的工作意义感、工作投入以及工作满意度等,进而快乐地工作。在系统梳理有关工作重塑的理论与实证研究文献的基础上,从工作重塑概念的解读、工作重塑的方式与方法、工作重塑的预测因素、工作重塑对个体与组织的影响以及工作重塑的培养策略等方面进行了综述,以便人们更深入地体会其丰富的理论内涵和实践价值;最后,该文指出未来工作重塑的研究应继续注重理论建构的丰富与完善、关注工作重塑的个体与群体差异性以及深化工作重塑与组织之间的关系研究。     

Individual Differences in Risky Decision Making: A Meta‐analysis of Sensation Seeking and Impulsivity with the Balloon Analogue Risk Task

To represent the state‐of‐the‐art in an effort to understand the relation between personality and risk taking, we selected a popular decision task with characteristics that parallel risk taking in the real world and two personality traits commonly believed to influence risk taking. A meta‐analysis is presented based on 22 studies of the Balloon Analogue Risk Task from which correlations with sensation seeking and impulsivity assessments could be obtained. Results calculated on a total of 2120 participants showed that effect size for the relation of sensation seeking with risk taking was in the small–moderate range ( = .14), whereas the effect size for impulsivity was just around the small effect size threshold ( = .10). Although we considered participants' demographics as moderators, we found only significantly larger effect sizes for the older adolescents and young adults compared with other ages. The findings of the present review supported the view that inconsistencies in personality–risk research were mostly due to random fluctuations of specific effect sizes, rather than to lack of theoretical ties or to measurement unreliability. It is also concluded that studies aimed at relating individual differences in personality to performance in experimental decision tasks need an appropriate sample size to achieve the power to produce significant results.

Intellectual Profiles and Violent Behavior in Juvenile Delinquents

Hemispheric laterality, measured by the Wechsler Verbal IQ-Performance IQ differential score, in a large group of delinquents (N = 101) was not associated with violent-nonviolent behavior. Delinquents were, however, likely to be relatively more impaired on verbal than on nonverbal intellectual capacities.
