Seeing yourself helps you see others

It has been proposed that self-face representations are involved in interpreting facial emotions of others. We experimentally primed participants' self-face representations. In Study 1, we assessed eye tracking patterns and performance on a facial emotion discrimination task, and in Study 2, we assessed emotion ratings between self and nonself groups. Results show that experimental priming of self-face representations increases visual exploration of faces, facilitates the speed of facial expression processing, and increases the emotional distance between expressions. These findings suggest that the ability to interpret facial expressions of others is intimately associated with the representations we have of our own faces.     

婴儿关于物体支撑的直觉性物理知识

支撑问题是儿童朴素物理理论知识结构中的重要部分, 是指关于一个物体放在固体平面上是否稳定以及如何才能稳定的问题。支撑问题目前有两种主要实验方法。此领域中的主要实验研究使用这两种方法, 探索了婴儿获得与支撑相关的直觉性物理知识的发展过程及“先建立核心性的初始概念, 再以此为基础增加各类变量”的规律。目前研究中存在“范式单一、缺乏各类研究相互印证”的问题, 有待未来的研究进一步发展。     

Improved EM algorithm for MPT model analysis

Multinomialprocessing tree (MPT) models are in wide use as measurement models for analyzing categorical data in cognitive experiments. The approach involves estimating parameters and conducting hypothesis tests involving parameters that are arrayed in a tree structure designed to represent latent cognitive processes. The standard inference algorithm for these models is based on the well-known expectationmaximization (EM) algorithm. On the basis of the original use of the EMalgorithm for MPT models, this article presents an approach that accelerates the convergence speed of the algorithm by (1) adjusting suitable initial positions for certain parameters to reduce required iterative times and (2) using a series of operations between/among a set of matrices that are specific to the original model structure and information to reduce the time required for a single iteration. As compared with traditional algorithms, the simulation results show that the proposed algorithm has superior efficiency in interpreted languages and also has better algorithm readability and structure flexibility.     

不同归因取向的表扬对儿童失败后的影响效应

以103名小学五年级的儿童为被试,考察不同归因取向的表扬对儿童遭遇失败后的影响效应。结果发现：（1）接受能力取向表扬的儿童在遭遇失败后表现出无助取向的反应模式,接受努力取向表扬的儿童表现出掌握取向的反应模式;（2）接受能力取向表扬的儿童倾向于采取防御性的失败归因策略,将失败更多地归因于测试焦虑,但其对能力因素的归因仍高于努力组和控制组,接受努力取向表扬的儿童更多地将失败归因于努力因素;（3）接受能力取向表扬的儿童表现出自我设限倾向,他们报告更多的测试焦虑,并缩短后测的做题时间和更低的后测成绩。     

童年中期对抗行为的发展及其与同伴拒绝、同伴接纳的关系

采用教师报告法对1254名城市儿童的对抗行为发展进行追踪研究,并采用交叉滞后设计探讨了对抗行为与同伴拒绝/接纳间的关系.结果发现:(1)童年中期,对抗行为呈中等程度稳定性,并表现出随年龄下降的趋势;(2)男生的对抗行为水平显著高于女生;(3)交叉滞后分析发现,早期的同伴拒绝能显著正向预测后期的对抗行为,但早期同伴接纳不能预测后期的对抗行为;早期的对抗行为均能够显著预测后期的同伴拒绝以及同伴接纳.     

学习困难与一般初中生过度自信特点的比较

采用比较研究的实验范式,从偏离校准、优于常人、控制错觉和过分乐观三个效应上比较学习困难初中生和一般初中生的过度自信特点。结果显示:(1)在"偏离校准"效应上,学习困难初中生在困难任务中和学习一般初中生同样存在过度自信的认知偏差,但在简单任务中则存在不自信。(2)在"优于常人"效应上,学习困难初中生和学习一般初中生都存在过度自信的认知偏差。简单任务中,他们认为自己"优于常人",而困难任务中,他们认为自己"差于常人"。(3)在"控制错觉和过分乐观"效应上,学习困难初中生和学习一般初中生都存在过度自信的认知偏差。男生比女生的过度自信程度更大。     

团体辅导改善大学生人际关系及心理健康水平的实证研究

目的:探讨团体心理辅导对改善大学生人际关系及心理健康水平的有效性及可行性。方法:采用单因素重复测量设计自然实验,对16名有改善人际关系愿望的大学生进行为期2个月,共10次的团体心理辅导干预;使用人际关系综合诊断量表和症状自评量表前后施测,结合团体成员的反馈自评和表现进行质的分析。结果:被试人际关系综合诊断量表前后测有差异(t=2.55,p<0.05),症状自评量表总分有显著差异(t=3.12,p<0.01),其中抑郁、敌对因子有显著差异(抑郁因子t=2.95,敌对因子t=2.71),人际关系和偏执因子有差异(人际关系因子t=2.53,偏执因子t=2.57)。结论:人际交往团体辅导对改善大学生的人际关系,提高心理健康水平是有效的。

Influences of head and torso movement before and during affordance perception

Previous research has shown that body sway (both standing and seated) is related to the accuracy of affordance judgments. The authors investigated the influence of seated head and torso movement on the perception of a novel affordance for wheelchair locomotion. Healthy adults without prior wheelchair experience judged the lowest lintel under which they could roll in the wheelchair. Prior to judgments, participants were given brief (≈ 2 min) practice at self-controlled wheelchair locomotion. During practice, the participant's head either was or was not restrained within the wheelchair. During the subsequent judgment session, the participant's head was or was not restrained. The accuracy of affordance judgments was influenced by restraint during the practice session and also by restraint during the judgment session. The authors collected data on head movement during the judgment session (when participants were not restrained). These data revealed that movement during judgment sessions was influenced by whether or not participants were restrained during the practice session. Overall, the results reveal that the availability of head movements (i.e., being unrestrained) and the nature of head movements (during unrestrained judgment sessions) were causally related to the accuracy of affordance judgments.     

Stability of peer victimization in early adolescence: effects of timing and duration

The current study investigated the stability of peer victimization and the impact of the timing and duration of victimization on psychological and academic outcomes for boys and girls on a sample of 863 middle school students. Results demonstrated strong support for the onset hypothesis and concurrent effects of maladjustment in anxiety, depression, self-esteem, poor school attitude, GPA, and attendance. Support for the cessation hypothesis was mixed, depending on the outcome and gender: boys demonstrated recovery from internalizing distress, whereas girls demonstrated residual effects, even after the cessation of victimization. Girls also demonstrated residual effects of victimization on grades, and both boys and girls evidenced residual effects of victimization on attendance. Regarding duration of victimization, there was strong support for the life-events model of stress and coping across almost all outcomes, suggesting that even temporary experiences of victimization could have a negative impact on psychological and academic outcomes. Overall, results demonstrated the importance of considering the timing and duration of victimization in understanding the risks and damaging effects of victimization. The results from this study also highlight both the need and the potential to intervene during early adolescence when peer relationships are taking on increasing importance, as well as the importance of helping students regain social-emotional and academic functioning, even after victimization ceases.
