儿童的假想伙伴:理论与实证研究

假想伙伴是在儿童生活中普遍存在的现象,研究者发现拥有假想伙伴的儿童约占52%至65%左右。尽管早在上世纪初就存在相关研究,但是直到近二十年它才获得众多学者关注,成为一个新兴领域。本文总结介绍了假想伙伴的早期背景,以及在理论与实证研究中取得的多方面成果,并且对该领域未来研究的发展方向提出了展望。     

目标定向对创造性个性的影响

基于创造性研究的社会心理学取向,本研究试图探讨目标定向干预对创造性个性的影响。对73名高一学生施以TARGET模式3个月以引导掌握定向的形成;另73名高一学生作为控制组。协方差分析表明,实验组的创造性个性有明显改善;被试实验前的目标定向对实验效果具有一定的影响,实验前成绩接近定向的倾向较弱的被试其创造性个性的改善较为明显。总之,目标定向干预可导致创造性个性的改善。     

附加点作用下两点距离的触觉辨别

在被动触觉的距离知觉实验中,被试的右手保持不动,将各种三点型式的刺激轻轻接触食指腹侧或以一定速度通过其表面,要求被试判定外侧两点的直线距离并在一根量尺上复现出来．结果发现：（１）当刺激快速通过皮肤表面时,外侧两点距离表现出低估,其知觉距离显著地小于刺激静止或慢速运动条件下的知觉距离;（２）当中间附加点偏离外侧两点间想象连线较大时,外侧两点的知觉距离显著地小于中间附加点偏离较小时的知觉距离,偏离较大的中间附加点似乎将外侧两点拉近了,缩短了其知觉距离,出现知觉亲和现象．这种现象与刺激是否运动无关．     

Event-related Desynchronization of Mu Rhythms During Concentric and Eccentric Contractions

The purpose of this study was to compare the electroencephalographic (EEG) patterns and reaction times (RTs) of muscle activation between concentric and eccentric biceps brachii contractions under the RT paradigm and to evaluate how the EEG patterns and RTs changed with practice. Sixteen subjects performed 3 sets of 30 repetitions of submaximal voluntary concentric and eccentric biceps contractions. RT, event-related desynchronization (ERD) patterns of mu rhythm onset, and ERD amplitudes were selectively analyzed. Mental demand decreased as familiarity with the motor action increased due to practice regardless of contraction type. However, the 2 types of muscle contractions still have differences in brain activity regardless of decreased mental demand: eccentric contractions require earlier preparation than concentric contractions.     

高难度材料的元记忆监测更受记忆广度的制约

以不同难度(有、无意义联系)的两种中文词对为记忆材料,随机选取在校大学生200名,采用经典的回忆-判断-再认(recall-judgement-recognition,RJR)范式,考察短时记忆广度和一般自我效能感对个体在不同难度材料上元记忆监测的影响。结果发现,相比于无意义联系的材料,个体在有意义联系的材料上,JOL、FOK和JOC判断等级更高,线索回忆测验成绩更好。但是,个体在不同材料上的JOL判断和线索回忆受短时记忆广度的调节。不同短时记忆广度的个体在有意义联系材料上的JOL判断等级和线索回忆测验成绩无显著差异,但是在无意义联系材料上,高短时记忆广度个体的JOL判断等级和线索回忆测验成绩均显著高于低短时记忆广度个体。同时,相关分析结果也发现,相比于低短时记忆广度的个体,高短时记忆广度的个体,其线索回忆测验成绩和再认测验成绩与JOL、FOK和JOC判断等级之间更加相关。实验结果表明,作为一种人格变量,一般自我效能感对个体元记忆监测的影响可能并不明显。而短时记忆广度,很大程度上反映了个体的记忆能力,是个体元记忆监测的一个重要影响因素,尤其是对难度较大的材料。     

Stress Moderates the Association between Action Orientation and Goal Internalization

The purpose of this study is to examine whether stress moderates the association between action-state orientation and goal internalization. People estimated how autonomous (vs. controlled) they would feel if they pursued goals of either an extrinsic or an intrinsic type. Measures of action orientation and stressful life events were also taken. Results showed that autonomy of goal motive for action orientation was moderated by stress (failure-related and demanding) situation. Action-oriented people have less internalized goal than state-oriented people in stress situation. Implication for self-determination theory and action-control theory is discussed.
