Improving Motor Performance During Initial Skills Acquisition Through Regulatory Fit: An Experimental Study Based on Ball Throwing Task and Small Financial Reward

Regulatory focus theory (RFT) suggests that performance will be enhanced when there is a match between individual characteristics and environmental cues. Given that the application of RFT in the context of motor performance has been rarely examined, a ball-throwing task with small financial reward was conducted to test the theory. A total of 51 undergraduate students participated in this study. They were randomly assigned to either the promotion- or prevention-oriented task (which were different in terms of how the reward was instructed to be given). Results indicated that students performed better on ball throwing when the given instruction fit their relatively dominant regulatory focus. This finding supports the expectations of RFT. Implications and limitations were discussed.     

So You,My Children,Can Have a Better Life: A Cambodian American Perspective on the Phenomenology of Intergenerational Communication about Trauma

We address this question: How do Cambodian American young adults come to know about their family’s experiences of trauma? Using a social constructivist critical ideological approach, we developed a phenomenological model describing intergenerational communication about trauma (IGCT) in Cambodian American families. We found IGCT to be an interactional process in which younger and older generations each played a role. IGCT was influenced by the availability of multiple sources of information and opportunities for learning, interpersonal connectedness between the generations, emotional distress tolerance, and having motivation to empathically learn and share. When these factors were abundant, direct interactive IGCT was more likely. When wanting, the IGCT was more disrupted and incoherent, filled with emotionally charged silence and lead to negative attributions. IGCT was a dynamic process that could change over time to accommodate developmental change. Limitations of the findings, clinical implications, and future directions are discussed.     

面孔可信度对助人行为的影响：依恋安全的调节作用

分别从特质依恋和状态依恋角度考察施助者的依恋安全在求助者面孔可信度与助人行为之间的调节作用。结果发现：(1)求助者面孔可信度影响助人行为, 面孔可信度高的求助者得到的助人行为显著多于面孔可信度低的求助者; (2)施助者的依恋安全调节求助者面孔可信度与助人行为之间的关系, 安全依恋能有效缓冲低面孔可信度带来助人行为下降的趋势。本研究结果表明依恋安全有助于提升社会安全感和促进亲社会行为, 因此应注重依恋安全的培养。     

青少年自我监控能力的发展研究

本研究用认知操作的部分内容,探索了青少年在认知操作活动中自我监控能力的发展特点,研究发现：随着年龄的增长,计划性中的初步思考时间延长,操作任务越难,初步思考时间越长,停顿次数越多,但停顿次数年龄差异不大;在监视性中的悔步次数逐渐减少,任务越复杂,悔步次数越从,短时注意次数年龄不大;在简单积木操作中,随年龄增长,长时注意次数延长;认知操作的总时间减少,在操作中的拼错数逐渐减少,但年龄差异不大。     

简明心境量表(POMS)在中国的试用报告

该研究引进ＰＯＭＳ,采用随机对照的方法将２８９名放化疗病人分成实验组和对照组,分别在治疗前中后测查三次,同时测查３８５名正常人,以验证其在中国大陆的适用情况。研究发现：ＰＯＭＳ各量表同质性信度高,三种方法检验的临床效度均较高,尤其是对心理干预的效果更敏感;但该问卷的区分效度不高,对正常人心境变化的敏感性不如对病人。由此得出,ＰＯＭＳ在中国大陆癌症病人中是可行的、可靠的、有效的和敏感的,可作为心理干预的一个敏感指标。     

6～12岁儿童脑电α波频率分布特点与信息加工速度的关系

本研究以 2 2 8名 6～ 12岁儿童为研究对象 ,采用脑电波超慢涨落分析技术 (简称ET) ,重点探讨了与认知功能有关的α波 ( 8～ 13Hz)的分布特点。研究结果表明 :①α波在全脑 12个脑区的比率 ,因频率成分不同而表现出不同的分布特点 ;②α波在左右对称脑区的分布比率也因频率不同而表现出不同的左右脑优势。除左前颞叶的平均频率显著大于右前颞叶外 ,其他左右脑对称区域的平均频率的差异均不显著。α波平均频率的从高到低依次为枕叶、中央区、顶叶、左前颞叶、后颞叶、额叶、右前颞叶 ;③信息加工速度与α波的关系并不明显 ,快组和慢组被试的 6种频率 ( 8～13Hz)α波的比率均无显著性差异     

预测特征竞争范式下的特征推理方式

当面临归类不确定的情景时,人们的特征推理是基于类别进行,还是基于特征联结进行,一直是类别研究中的重要内容。本研究采用预测特征竞争范式对这一问题进行了探究。共两个实验：实验1采用预测特征竞争范式探讨推理前预先归类时,人们的推理方式是基于类别还是基于特征联结。实验2采用预测特征竞争范式探讨推理前不预先归类时,人们的推理是基于类别还是基于特征联结。实验结果表明,推理前预先归类时,被试倾向于基于类别进行推理。推理前不预先归类时,被试倾向于根据特征联结进行推理。     

Using system dynamics modeling to understand the impact of social change initiatives

Community psychologists have a long history of interest in understanding social systems and how to bring about enduring positive change in these systems. However, the methods that community psychologists use to anticipate and evaluate the changes that result from system change efforts are less well developed. In the current paper, we introduce readers to system dynamics modeling, an action research approach to studying complex systems and the consequences of system change. We illustrate this approach by describing a system dynamics model of educational reform. We provide readers with an introduction to system dynamics modeling, as well as describe the strengths and limitations of the approach for application to community psychology.     

小学生代数运算规则的样例学习

采用完整或不完整样例,对180名六年级小学生用样例学习两种代数运算规则进行了实验研究。结果显示：多数被试难以学会“平方差”运算规则,只有少数被试学会了“完全平方和”运算规则;反馈对不完整样例的学习效果有促进作用;用不完整样例学习难度不同的规则,其效果不同;在无反馈条件下,完整样例的学习效果都好于不完整样例;在有反馈的情况下,只有删除一步运算步骤样例的学习效果比完整样例的学习效果好     

脂多糖免疫激活导致抑郁性行为的动物研究：剂量和时程效应

“抑郁症细胞因子假说”的提出为抑郁障碍的病因学研究提供了一个新的方向,为了探讨脂多糖（lipopolyaccharide,LPS）诱导的免疫激活与抑郁性行为产生之间的关系,本研究采用50只SD大鼠随机分为五组LPS400,LPS200,LPS50,LPS10,LPS0,分别于实验期第0天和第3天注入LPS400ug/kg,,200ug/kg,50ug/kg,10ug/kg和生理盐水。以糖精水偏爱,旷场行为和高架十字迷宫评定大鼠LPS注射后2小时,24小时,48小时的行为变化。结果显示一次LPS注射后2小时,LPS50,LPS200,LPS400组动物与生理盐水组动物相比较,其糖精水偏爱分数（p<0.01）,旷场中的水平活动距离(p<0.01)和直立行为(p<0.01)以及高架十字迷宫中的闭合臂进入次数(p<0.01)和开放臂进入次数显著下降(p<0.01);重复注射后2小时LPS注射组动物的闭合臂进入次数显著降低（p<0.01）;但LPS10组与生理盐水组动物在行为上没有差异,50ug/kg,200ug/kg和400ug/kg剂量的各组之间没有差异。LPS注射后24小时和48小时以及重复注射后大鼠的行为没有发现显著变化。提示LPS诱导的免疫激活对抑郁行为产生有一定的作用。免疫激活的细胞因子能够导致动物出现明显的抑郁性行为,但是这种行为缺乏长时程效应,因此LPS诱导的抑郁障碍的动物模型应用是非常有限的。免疫激活的前炎性细胞因子可能是导致抑郁障碍产生的其中一个原因而不是唯一原因。
