DRD2基因TaqIA多态性与同伴侵害对青少年早期抑郁的交互作用

本研究运用问卷法与DNA分型技术,对1063名青少年(初次测评年龄为12.32±0.47岁,50.3%女生)进行间隔2年的追踪调查,考察DRD2基因TaqIA多态性与同伴身体侵害和关系侵害对青少年早期抑郁的交互作用及其性别差异。结果发现,TaqIA多态性与身体侵害、关系侵害均对男青少年抑郁存在显著的交互作用。在携带A2A2基因型的男生中,身体侵害和关系侵害可以显著正向预测其抑郁水平,而在携带A1等位基因的男生中,同伴侵害对抑郁无预测作用。此外,TaqIA多态性与身体侵害、关系侵害对女生抑郁均无显著交互作用。研究结果提示,同伴侵害是一种重要的候选环境指标,与TaqIA多态性交互影响青少年早期抑郁,并且性别在这一基因×环境交互作用中起到重要的调节效应。     

表征动量的朝向效应

本研究通过4个实验探索运动物体的朝向对表征动量的影响。4个实验均使用了2(朝向：正向vs.倒向)×2(运动方向：左vs.右/上vs.下)两因素实验设计。前3个实验使用不同的刺激材料进行水平方向的诱导运动, 结果发现, 正向运动的前移量大于倒向运动的前移量, 但这种朝向效应仅仅作用于水平向右方向, 即运动方向水平向左时朝向效应消失。实验4将运动方向改为垂直运动, 结果发现, 正向运动的前移量大于倒向运动的前移量, 但这种朝向效应仅仅作用于垂直向下方向, 即运动方向垂直向上时朝向效应消失。结论：朝向影响表征动量, 但仅作用于水平向右和垂直向下方向上, 前者可能和阅读习惯有关, 后者可能和重力作用有关。     

大学毕业生目标自主性与无望感:社会支持与性别的作用

大学毕业生面临重要的生活转折, 其个人目标自主性对未来的无望感有显著影响。本研究以192名大四毕业生为被试, 采用特殊目标测量法考察个人目标自主性, 用问卷评价社会支持与无望感, 探讨目标自主性与无望感的关系, 并分析社会支持和性别的作用。结果发现:(1)毕业前夕去向已经确定的大学生, 无望感更低;(2)大四毕业生目标自主性越高, 对未来的无望感越低;(3)目标自主性对无望感的预测受到性别因素调节。对于男生, 高目标自主性能够显著降低无望感;对于女生, 目标自主性对无望感的预测作用不显著;(4)社会支持对于目标自主性与无望感之间的关系没有显著的调节作用, 但是社会支持越高, 其无望感越低。由此可见, 大学毕业生建立自主的个人目标和改善社会支持对降低无望感具有重要意义, 目标自主性的效应对男生尤为明显。     

宗教信仰对亲社会行为的影响

以往研究发现宗教信仰与亲社会行为之间存在显著的正相关, 据此研究者提出“信仰-亲社会假设”试图证实两者的因果关系。本文主要从研究方法、影响因素及心理机制三个方面对信仰影响亲社会行为的研究进展进行介绍和评述。在研究早期, 研究者主要考察宗教信仰的归属身份对个体亲社会行为的影响; 而近年来, 研究者则越来越关注信仰启动对亲社会行为的影响。信仰对亲社会行为的作用受到信仰程度、文化背景、信仰认知和信仰取向等多种因素的影响。未来研究需要有效控制宗教信仰身份对亲社会测量的影响, 明确宗教信仰的操作性定义并改进相关的测量指标, 关注精神性的作用机制、“信仰-亲社会假设”的跨文化效应以及信仰概念对非宗教信仰群体的影响。     

表象预期调控生物运动性别信息的识别

生物运动系在运动的生物体身的关键节点安置12～15个光点的运动痕迹形成的动画。研究表明光点生物运动包含了丰富的社会性信息,其社会性信息的识别涉及多个心理活动过程,其中大脑自上而下的知觉调控过程发挥重要作用。本研究通过两个实验探讨了表象预期在大脑自上而下调控光点生物运动性别信息识别的作用。结果发现：（1）表象预期能够加快男性生物运动的性别识别速度;想象中性形象被试倾向于将性别中立的生物运动识别为中性,而较少为男性或者女性。（2）表象预期条件和无表象预期条件下性别中立的光点生物运动性别类型识别都表现出“男性偏差”现象。（3）反应类型能够影响生物运动的性别识别。本研究有利于揭示大脑自上而下调控光点生物运动性别信息识别的心理机制。     

Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder

Lambek, R., Trillingsgaard, A., Kadesjö, B., Damm, D. & Thomsen, P. H. (2010). Gender differences on the Five to Fifteen questionnaire in a non‐referred sample with inattention and hyperactivity‐impulsivity and a clinic‐referred sample with hyperkinetic disorder. Scandinavian Journal of Psychology 51, 540–447. The aim of the present study was to examine gender differences in children with inattention, hyperactivity, and impulsivity on the Five to Fifteen (FTF) parent questionnaire. First, non‐referred girls (n = 43) and boys (n = 51) with problems of attention and hyperactivity‐impulsivity and then clinic‐referred girls (n = 35) and boys (n = 66) with hyperkinetic disorder (HKD) were compared on the FTF. Results suggested that non‐referred boys were more hyperactive‐impulsive than non‐referred girls, whereas clinic‐referred boys and girl with HKD were more similar than dissimilar on the FTF questionnaire. Secondly, it was examined whether the application of gender mixed norms versus gender specific norms would result in varying proportions of clinic‐referred children with HKD being identified as impaired on the subdomains of the FTF questionnaire. Based on results it was concluded that the use of a gender mixed normative sample may lead to overestimation of impairment in boys with HKD, but the type of sample applied to define impairment on the FTF should depend on the purpose for applying the questionnaire.     

Mechanisms of moral disengagement and their differential use by right‐wing authoritarianism and social dominance orientation in support of war

Right‐wing authoritarianism (RWA) and social dominance orientation (SDO) are associated with the approval of war as a political intervention [McFarland, 2005]. We examined whether the effects of RWA and SDO on war support are mediated by moral‐disengagement mechanisms [i.e., responsibility reduction, moral justification, minimizing consequences, and dehumanizing–blaming victims; Bandura, 1999] and whether the ideologies use the mechanisms differently. Our data were consistent with the possibility that minimizing consequences (Study 1) and moral justification (Study 2) mediate the effects of RWA and SDO on approval of war. Both ideologies were positively associated with all moral‐disengagement mechanism though more strongly so for RWA. Comparisons within ideologies suggest that RWA was most strongly associated with moral justification and SDO was most strongly associated with dehumanizing–blaming victims. We discuss implications and limitations. Aggr. Behav. 36:238–250, 2010. © 2010 Wiley‐Liss, Inc.     

The family as its own reflecting team: a family therapy method

Social research has suggested that people, in general, tend to overestimate their skills and abilities. Interestingly, research has found that peers are better predictors of a person's behaviour than self‐assessment, suggesting that others know us better than we know ourselves. Family therapists should be aware that family members might not give accurate accounts of themselves. In order to overcome this problem, therapists should incorporate peer assessments into therapy. Reflecting teams and videotaping do incorporate peer assessments, yet these methods can be impractical. This article describes a method of family therapy using enactments as a means of setting up the family as its own reflecting team. The method suggests that the family and therapist switch roles several times during the enactment, and then encourages a discussion on the peer observations on how each person addresses a problem in the family. Case examples illustrate how feedback from peers promotes insights.     

流动儿童的未来取向及与学业卷入的关系

采用问卷法,选取755名初中生(其中流动儿童562名)作为被试,对未来取向及其与学业卷入的关系进行考察。结果表明:(1)打工子弟学校流动儿童的未来取向与公立学校流动儿童、城市儿童差异较大,具体表现为,打工子弟学校流动儿童的受教育领域未来目标显著较少,未来职业目标较多;未来计划得分显著较低;未来评价方面,打工子弟学校的流动儿童具有较少的内部归因,乐观性也较弱;(2)打工子弟学校的流动儿童未来取向主要表现出了年级差异,初一年级受教育目标显著高于初二年级,而未来职业内部归因显著低于初二年级;公立学校流动儿童则表现出了性别差异,男生在各领域上的外部归因和乐观性均显著高于女生;(3)教育计划和乐观性对流动儿童的行为卷入得分有显著的正向预测作用,教育的外部归因和未来的职业计划有着显著的负向预测作用;流动儿童的未来受教育计划、教育目标和乐观性以及职业的内部归因对其心理卷入有显著的正向预测作用。
