农村留守儿童的抑郁和反社会行为:日常积极事件的保护作用

以来自河南省农村的410名农村留守儿童(双亲外出和单亲外出)和非留守儿童为被试,考察了日常烦恼这一危险因素与儿童抑郁、反社会行为的关系,并探讨了日常积极事件在其中的保护作用。结果表明,儿童经历的日常烦恼越多,其抑郁和反社会行为水平越高。日常积极事件表现出了对儿童抑郁和反社会行为的改善效应,但是因儿童留守类别的不同而不同:日常积极事件对单亲外出儿童和非留守儿童抑郁的改善效应较强,对双亲外出儿童反社会行为的改善效应较强。此外,日常积极事件还可以有效抵抗日常烦恼对儿童反社会行为的不利影响。     

热休克蛋白7O在动脉粥样硬化发病中的双重作用

大多研究表明,热休克蛋白70通过抗凋亡、抗氧化及抗炎症反应而在动脉粥样硬化发病中起保护作用。但亦有研究表明,热休克蛋白70通过促凋亡、促进炎症反应而在动脉粥样硬化的发生发展中起促进作用。说明热休克蛋白70在动脉粥样硬化发病中有双重作用,进行基础研究和临床干预时应考虑到其双面性。     

The association between reality-based beliefs and indirectly experienced traumatization

The purpose of the study was to examine the association between belief types and the magnitude of indirect traumatization. Specific types of beliefs were defined in terms of the cognitive orientation theory, which is a cognitive-motivational approach to the understanding, predicting, and changing of behaviors. Belief types that were analyzed included beliefs about self, general beliefs, beliefs about norms, and goal beliefs as they relate to personal growth. Study participants included 38 rescuers (body handlers), 37 nurses, and 31 rehabilitation workers who treated injured civilians that had been exposed to politically motivated violence. The Cognitive Orientation for Posttraumatic Growth Scale was used to assess beliefs about personal growth. The Revised Posttraumatic Stress Disorder Inventory was administered to evaluate indirect traumatization. The results indicate that three of the four belief types related to personal growth were associated with the level of indirect traumatization. Optimistic and positive beliefs about self and general beliefs were associated with a lower level of indirect traumatization symptomatology, suggesting that these types of beliefs may counteract indirect traumatization. On the other hand, stronger goal beliefs were associated with greater indirect traumatization. The negative association between positive goal beliefs and indirect trauma may be related to the gap the individual perceives between the hoped-for ideals and the trauma-stricken reality. These results indicate the importance of cognitive beliefs and their possible role in determining the response to indirect traumatization.     

Infants' perception of human body orientation and the effect of a surrounding square

We examined two hypotheses about infants' perception of orientation. The first is that infants develop an expectation that the human body is normally vertical. To examine this hypothesis, we compared the preferential looking to vertical and oblique versions of a silhouette of a human body, to an inverted body, and to a grating. Our second hypothesis is that presenting a figure inside a frame affects the perception of orientation. To examine the second hypothesis, we placed the figure inside a surrounding square that was oriented normally or at an oblique angle. Four‐ to seven‐month‐old infants (N = 78) participated. The results showed that 6–7‐month‐old infants preferred the oblique human body presented upright; no such preference was observed for the inverted body or the grating. For all types of displays, the surrounding square influenced preferences. Our results suggest that (a) 6–7‐month‐old infants have specific expectations about the orientation of the human body, and (b) surrounding displays with a square could influence the perception of the orientation of the human body, as well as that of a grating.     

5岁儿童对熟悉面孔的特征信息识别

关于儿童面孔认知的已有研究大多未曾控制好实验材料的熟悉度。研究选用10个同班同学的面孔作为材料,考察了5岁儿童对熟悉面孔的识别特点。结果发现,5岁儿童能准确辨认同伴的面孔。依赖面孔的部分信息(内、外轮廓)甚至单一部件(眼睛),儿童辨认同伴面孔的成绩就可以高于随机水平。儿童的面孔识别模式和成人相似,辨认内轮廓的绩效高于外轮廓,眼睛的绩效高于鼻子和嘴巴。儿童识别自我面孔的模式和成人相反,辨认他人面孔的成绩好于辨认自我面孔。实验证明熟悉度是影响儿童面孔识别绩效的重要因素。     

大学生内隐职业性别刻板印象研究

采用内隐联想测验和刻板解释偏差两种测量内隐社会认知的方法考察了60名大学生被试的内隐职业性别刻板印象。结果表明,大学生也存在非常明显的内隐职业性别刻板印象,刻板程度在性别、专业上没有显著差异。在男女职业评价刻板印象上,男大学生表现出非常明显的刻板印象,女大学生的观念已有所改变。用内隐联想测验和刻板解释偏差测量这两种方法测量大学生的内隐职业性别刻板印象,在被试的性别变量上得到的结果不一致。     

未来取向研究概述

未来取向是指个人的思想和行为偏好未来的方向, 同时也是个体对于未来的思考和规划过程。未来取向心理结构的代表性观点有要素观、过程观和动机认知行为观。主要测量方式包括问卷法、投射法、圆环测验、讲故事技术和完成故事技术。个体的年龄、性别、人格和情绪等是未来取向的主要影响因素。未来取向在健康行为、物质滥用和学业成绩等方面起着积极作用。明确未来取向的功能机制、完善测量工具、采用精巧的实验设计并进一步探讨未来取向的脑机制是未来研究的方向。     

情绪加工的性别差异及神经机制

已有研究表明, 情绪加工存在显著性别差异。这主要表现为女性人群具有情绪识别优势, 更好的情绪记忆能力与更强的负性情绪易感性。此外, 情绪加工的性别差异也表现为情绪调节过程的不同：相比男性, 女性更善于抑制情绪行为, 却较难通过认知策略调节负性情绪。情绪加工的性别差异有重要生理基础, 与情绪脑结构, 荷尔蒙水平的男女差异有关。同时, 情绪加工的性别差异同女性更高的情绪障碍易感性有着密切联系：不善于调节负性情绪, 及更强的消极情绪易感性可能是女性更易患情绪障碍的重要原因。从情绪加工角度探讨情绪障碍的性别差异及其原因, 对于情绪障碍的预防和治疗具有重要意义。     

测量和观察法在亲子沟通研究中的应用

亲子沟通研究主要采用量表测量和观察两种方法收集数据, 通过对有关实证研究的综述, 发现亲子沟通研究在测量工具发展和实验任务创设与分析方面存在理论基础薄弱、工具建设缺乏理论指导、数据编码与整理思路不清晰等问题, 未来的亲子沟通研究应在这些方面有所改进和突破。
