光栅朝向分辨学习中存在关于45°对角线对称的镜像迁

采用光栅朝向分辨任务来探讨视知觉学习中是否存在关于45°对角线对称的镜像迁移现象。训练被试分辨15°或75°朝向3或5天,每天约1小时,训练前后测量15°、75°、45°朝向的分辨阈值。通过训练,训练朝向（15°或75°）的阈值下降,该学习效应没有迁移至45°朝向,但基本迁移到关于45°对称的朝向（75°或15°）上。这提示,视知觉学习可能发生在中间视皮层,该皮层同时具有一定的朝向特异性和关于45°对角线对称的镜像迁移性     

社会支配倾向研究述评

社会支配倾向是社会支配理论中的一个概念,它反映了个体期望内群体优于和支配外群体的程度。高社会支配倾向者偏好加大不同群体间的阶层差异,并期望优势群体更多地支配劣势群体;低社会支配倾向者偏好缩小不同群体间的阶层差异以增加社会平等,并期望优势群体更少地支配劣势群体。因此,社会支配倾向会影响社会不平等的程度,并可以被用来解释偏见的形成。性别和群体地位等情境因素会对社会支配倾向产生影响,而且社会支配倾向与个体间的支配也是有关系的     

初中生成就目标定向、学习策略与学业成绩之间的关系研究

以432名初中学生为被试,通过问卷调查,考察初中生成就目标定向、学习策略与学业成绩之间的关系。结果表明：成就目标定向、学习策略对学业成绩均存在显著的总体影响,其中学习策略对学业成绩产生显著的直接影响,并且主要是通过认知策略和动机策略来产生;成就目标定向对学业成绩不存在显著的直接影响,但通过学习策略这个中介变量产生显著的间接影响。成就目标定向主要是通过元认知策略对学习策略产生显著的直接影响。     

Looking at You or Looking Elsewhere: The Influence of Head Orientation on the Signal Value of Emotional Facial Expressions

The role of horizontal head tilt for the perceptions of emotional facial expressions was examined. For this, a total of 387 participants rated facial expressions of anger, fear, sadness, and happiness, as well as neutral expressions shown by two men and two women in either a direct or an averted face angle. Decoding accuracy, attributions of dominance and affiliation, emotional reactions of the perceivers, and the felt desire to approach the expresser were assessed. Head position was found to strongly influence reactions to anger and fear but less so for other emotions. Direct anger expressions were more accurately decoded, perceived as less affiliative, and elicited higher levels of anxiousness and repulsion, as well as less desire to approach than did averted anger expressions. Conversely, for fear expressions averted faces elicited more negative affect in the perceiver. These findings suggest that horizontal head position is an important cue for the assessment of threat.

SCI/SSCI心理学源期刊的计量分析

采用文献计量学方法,利用JCR对2004年SCI、SSCI收录的455种心理学期刊进行了统计分析与对比研究,以揭示其基本特点与存在的问题,并引发了关于心理学学科分类的思考。推荐了2004年国际影响力最大的28种心理学期刊,供我国同类期刊工作者及心理学者借鉴。最后讨论了如何使我国同类期刊进入SCI/SSCI,及如何在投稿中进行更好的理性思维。     

自我参照和环境参照整合过程中的主方位判断

通过三个实验证明,自我参照和环境参照转化与整合过程中的主方位判断受拍摄方向和目标位置的影响。二者对主方位判断的作用模式不会随主方位判断任务的改变而改变,拍摄方向效表现为：朝北效应（匹配效应）和主方位效应,体现的是自我参照和环境参照整合过程中环境参照对主方位的影响;目标位置效应的认知加工时间模式可表示为：前-后轴<左-右轴<其他位置,体现的是自我参照和环境参照整合过程中自我参照对主方位的影响。本文以规范轴和规范方向为框架对数据结果进行了分析和解释。     

成人期人际性问题解决的策略取向研究

采用开放式问卷,考察252名25至75岁的成人解决人际性问题的策略取向。结果表明：总体上中国成人偏重于二级控制取向;成人前期个体较其他年龄段成人表现出更多的一级控制取向;情境因素对成人的策略取向有较大影响,并且这种影响对不同年龄段成人所产生的效应存在明显差异。     

触觉空间精确性与触觉神经元密度相关联的验证

本研究应用栅栏定向任务,通过对小学一年级儿童和大学生的触觉敏感性的比较,验证触觉敏感性与神经元密度的关系。结果表明：对较大的易于分辨的刺激,成人可以完成得较好,而对较细小的难于分辨的刺激,儿童成绩更好。本研究验证了高感受单元密度对应较强的触觉敏感性的假设。     

Thinking about the past,present, and future: Time perspective and self-esteem in adolescents,young adults,middle-aged adults,and older adults

We examined time perspective and self-esteem in adolescents, young adults, middle-aged adults, and older adults. Time perspective was measured with scales that assess relative orientations and relationships among the past, present, and future. Age effects were examined with standard analytic strategies to determine categorical differences between age groups and with new statistical techniques designed to show continuous age patterns. Findings indicated that (1) thinking about the future was greatest for adolescents and young adults and lowest for middle-aged and older adults, and thinking about the present increased across ages; (2) fewer adolescents and middle-aged participants perceived that the time periods were interrelated compared to younger and older adults; and (3) across ages, a greater emphasis towards the past compared to other time periods was associated with lower self-esteem, whereas emphasizing the present and the future jointly was associated with higher self-esteem.     

The effect of prompting and reinforcement of activity in elderly demented inpatients

On a ward for 24 psychogeriatric patients, 18 were randomly assigned to three groups with different experimental conditions. The first group was prompted and reinforced for different activities; the second was only prompted; and the third served as a control group. Activities, both the trained ones and others, were continuously monitored throughout the five week study. The results showed a clear increase in the trained activities after training. The prompting condition was effective, and the addition of reinforcement did not add any to the effects. There was no generalization to untrained activities, and the effects did not last at the 1 hr or 21 hr assessments, but was clearly visible at 5 min after training. Time seemed to be more important than place, i.e. the effect ceased with elapsed time, not because of changes in the situation.
