以124名小学六年级学生为被试。采用应用题解决问卷考查了我国小学生应用题表征的类型和特点。结果表明小学生应用题的表征方式有复述内容、图式表征、图片表征、直译表征、语义结构分析等;成功解题者和不成功解题者对各种表征方式的使用次数上没有显着差异;成功解题者和不成功解题者在各种表征方式下的解题成绩有显着差异,成功解题者在图式表征、直译表征和语义结构分析表征下的成绩显着优于不成功解题者。     

不诚实行为的认知神经机制

说谎,作为人性的一方面,已经成为心理学、生物进化学、实验经济学等多学科的关注点。说谎会受到多种文化的谴责,说谎行为也是人们所不支持的。但是国外的研究发现,在普通人群中,不诚实行为也是普遍存在的,而且这种不诚实行为并没有影响被试诚实的自我概念。因此了解这种不诚实行为的发生、发展过程,对人们认识和识别不诚实行为,提高人际互动质量至关重要。本文从不诚实行为的发生、发展过程出发,重点介绍了不诚实行为的研究范式、认知神经机制和影响因素。并针对已有研究的不足:(1)实验结果的解释水平低;(2)变量操纵不严谨;(3)研究方法局限; 提出了可能的解决方案。     

Prosocial Attitudes toward Money from Terror Management Perspective: Death Transcendence through Spirituality

Based on Terror Management Theory (TMT), we suggest that spirituality and prosocial attitudes toward money have a similar defensive function in resisting existential anxiety. In mortality salient (MS) situations, both spirituality and prosocial money attitudes afford symbolic immortality by self-transcendent connections. In four studies, we found that activating death awareness weakened people’s subjective love of money (Study 1) and predicted increased spending willingness on prosocial rather than proself goals (Studies 2, 3, and 4). More importantly, MS effects on money attitudes were smaller when people’s trait spirituality was high (vs. low; Studies 1, 2, 3) and when people were primed to experience spirituality (vs. happiness control condition; Study 4). For low spirituality people, the association between MS and prosocial spending also depended on the capacity of money spending to contribute positively to one’s feelings of self-worth (Study 3). Theoretical implications and future directions are discussed.     

数字加工的脑功能成像研究进展及其皮层定位

数字加工是人类最重要的认知功能之一。当前的脑功能成像研究有助于对数字加工与皮层之间的联系进行更精确的定位。基于对上世纪80年代来有关数字加工脑功能成像研究的主要成果的回顾,尤其是一些重要区域,如双侧顶叶与前额叶等在数字加工中的地位与作用,以及不同脑区之间的关系进行了探讨,并对一个广泛运用的数字加工神经机制模型进行了简要评述。在此基础上,对数字加工的皮层定位问题进行了简要的总结。     

Plasticity of nonneuronal brain tissue: roles in developmental disorders

Neuronal and nonneuronal plasticity are both affected by environmental and experiential factors. Remodeling of existing neurons induced by such factors has been observed throughout the brain, and includes alterations in dendritic field dimensions, synaptogenesis, and synaptic morphology. The brain loci affected by these plastic neuronal changes are dependent on the type of experience and learning. Increased neurogenesis in the hippocampal dentate gyrus is a well-documented response to environmental complexity ("enrichment") and learning. Exposure to challenging experiences and learning opportunities also alters existing glial cells (i.e., astrocytes and oligodendrocytes), and up-regulates gliogenesis, in the cerebral cortex and cerebellum. Such glial plasticity often parallels neuronal remodeling in both time and place, and this enhanced morphological synergism may be important for optimizing the functional interaction between glial cells and neurons. Aberrant structural plasticity of nonneuronal elements is a contributing factor, as is aberrant neuron plasticity, to neurological and developmental disorders such as epilepsy, autism, and mental retardation (i.e., fragile X syndrome). Some of these nonneuronal pathologies include abnormal cerebral and cerebellar white matter and myelin-related proteins in autism; abnormal myelin basic protein in fragile X syndrome (FXS); and abnormal astrocytes in autism, FXS, and epilepsy. A number of recent studies demonstrate the possibility of using environmental and experiential intervention to reduce or ameliorate some of the neuronal and nonneuronal abnormalities, as well as behavioral deficits, present in these neurological and developmental disorders.     

Clients' attributions of recalled important or helpful events in a counseling interview

Clients' causal explanations for recalled important or helpful events between those of early and of late sessions of counseling interview have been examined. We predicted that (a) for clients' recalled important or helpful events, there will be more internal attribution in late than in early sessions and (b) clients' evaluation of counseling sessions would be positively related to their internal attribution of the recalled important or helpful events. Data were generated from 84 sessions of therapy, with 12 counselor-client dyads conducting seven sessions of therapeutic interviews each. Immediately after each interview, clients were requested to recall and explain the most important or helpful events that happened during the session. Clients' causal explanations of the events were analyzed by two trained judges. Results showed no statistically significant differences in frequencies of internal attribution. Similarly, internal attribution did not covary with clients' evaluation of counseling sessions. The implications of the results are discussed.     

在"理性史"与"理念诗"之间--哲学史上经典之解释与人物之个性的关系问题

本论文所欲讨论者,将主要集中于哲学史上个人之性情、个性对该哲学本文所表达之观念的影响,以及我们对此所应持的诠释态度。对于中国传统哲学而言,经典本文之理解与人物个性之品评当得其有机之结合,方能再现“理性史之纹路”与“理念诗之魅力”,如是,我们也便有相当的理由质疑那种一开始就用某种预设了的、严格的因果对应的方式来图解思想家之思想的努力,同时,我们也可以在相当程度上避免因“过度诠释”所导致的诠释者对本文及其所赖于产生的周围世界的轻忽和放逐。     

印度的婆罗门教、佛教与中国的儒家、道家

印度的婆罗门教和中国的儒家学说都有着维护社会秩序、延续既有文明、创造符号体系的建构功能 ;与此相对立 ,印度的佛家和中国的道家学说则以反向解构的姿态分别对婆罗门教和儒家学说在民族文化的建构过程中所导致的异化现象进行了深刻的批判。这种建构与解构的关系体现了追求文明与反抗异化、积极进取与消极无为、崇尚秩序与回归自然之间的辩证关系。作为这种逻辑关系的历史性发展 ,印度宗教文化从婆罗门教到佛教再到印度教的发展过程 ,与中国世俗文化中儒家和道家之间的彼此更迭 ,都形成着“否定之否定”式的阶段性变革。     

本族和异族面孔的视觉工作记忆容量:面孔特征的影响

采用延迟探测刺激匹配再认任务,考察面孔种族和内外部特征是否会影响面孔视觉工作记忆容量。被试先识记2或4张中国人或白人的真实面孔图片,一半有内部特征(眼睛、鼻子和嘴巴),另一半有内部和外部特征(脸型、发型),再进行面孔再认判断。采用Cowan’s K值的分析显示,我国被试对本族和异族面孔的视觉工作记忆容量没有差异,但面孔数量与特征多少会影响面孔工作记忆容量,表明对本族和异族面孔的视觉加工不同。     

学校群体构成对流动儿童数学学业成就的影响:一项多水平分析

学校群体构成是影响儿童学业成就的重要环境变量,并对流动儿童具有不同于本地儿童的特殊效应。本研究数据来自"中国儿童青少年心理发育特征调查"项目建立的数据库,被试是我国发达地区32个区县141所学校的4960名2-6年级儿童,流动儿童所占比例为14.5%。结果发现:(1)无论流动儿童还是本地儿童,学校社会经济地位越高,儿童的数学学业成就越好;学校流动儿童比例对儿童的数学学业成就没有影响;(2)学校社会经济地位越高,短期流动儿童相对于本地儿童的数学学业劣势越大;(3)学校流动儿童比例越高,长期流动儿童相对于本地儿童的数学学业劣势越小。
