人类超常记忆的认知神经科学研究综述

借助脑成像技术,人类超常记忆研究揭示出:世界记忆大师与常人存在显著的脑功能差异,如海马等区域的激活;随着领域内训练增加,知识与经验逐渐取代一般能力来影响记忆活动,如在空间记忆任务上相关脑区激活量减少且集中;行为层面的记忆理论找到了相应的电生理基础,如国际象棋记忆的"组块"位于颞叶,音乐领域的"长时工作记忆"与脑区负波有关.同时,期待更多从生理层面上来揭示人类超常记忆能力实质的研究.     

社会比较方向及目标可达性对行为水平的影响

采用“错觉合取效应”实验材料,以正确率和反应时为行为水平的指标,探讨在coaetion的情景下．不同的社会比较方向及比较目标的可达性对个体任务操作水平的影响。结果发现,成绩差异量越大．可达性越低：无论个体进行上行比较还是下行比较,当成绩差异量为20％时,其行为水平显著高于其他成绩差异量时的行为水平。上行比较时,不同的成绩差异量,任务操作的正确率由高到低依次为：20％、30％、10％、40％;下行比较时．不同的成绩差异量,任务操作的正确率由高到低依次为：20％、10％、30％、40％。对个体心理紧张度进行方差分析发现,当个体进行上行比较时,心理紧张度显著高于下行比较。     

The Distance from Psychological Research to Real Life

Considering our experiences in everyday life, the result of research based on sample assumed to be derived from a “population” cannot afford individual predictions. That is because the variabilities within individuals which play an important role in actual psychological processes are erased from the data in samples-based studies. In this article, we begin the discussion with how the intra-individual variance contributes to individual prediction. As case study works on the basis of variability within each individual, it explores the intrinsic mechanism of development and emphasize the connection between person and environment. The question of how to generalize from case studies requires that the researcher to selectively consider some of the variance and construction of a hypothetical model that shows how different features of oppositions (Yin and Yang) are integrated into an abstract whole that is applicable to all individual cases.

医学中的奇葩——文艺医学

美国一位心理学家曾对50名有各种精神创伤而没有器质性疾病的人进行对照试验。6个月后证实,那些认真写日记的人,各项免疫指标得到改善,就医次数减少,精神状况明显改善,而不写日记的人则没有这种改变;有一位严重失眠的患者,根据医生的指导将卧室以黄、白二色修饰,避免青色和红     

延迟时间与反应设置对任务切换的影响

采用任务线索范式,探讨了在不同反应设置条件下,延迟时间对任务切换的影响,以揭示在延迟时间内之前任务设置延迟的认知加工。以切换代价为主要测量指标,结果表明,反应设置和延迟时间的主效应均不显著,但是二者的交互作用显著。简单效应分析发现,在双向设置条件下,切换代价随着延迟时间的延长而显著减少,但是在单向设置条件下无显著差异。这说明,在任务切换中反应设置对延迟时间的影响效应具有调节作用。由此可见,在延迟时间内之前任务设置延迟的是反应设置。     

归因方式对心理健康的影响及干预研究之概观

该文就归因方式对心理健康影响的特点、规律及其心理机制以及通过归因干预改善和提高个体与群体健康水平的研究进行了简要的叙述,并对已有研究存在的问题进行了初步的讨论。作者认为,归因干预可能是改善和提高个体与群体的健康水平的一条重要途径;未来的研究应着眼于揭示个体对不同性质、不同类型的生活事件在特定归因和维度归因上对心理健康影响的特点、规律及其心理机制,并就归因干预的理论和实践等问题进行了深入的探讨。     

千年误读:驳孟子"迂阔"论

二千多年来孟子一直被视为“迂阔”的典型,历史的偏见至今未得到彻底的厘清。其实孟子是位坚定的现实主义者,其学术的基调是坚持从实际出发,其哲学的根本精神是强调实事求是。孟子反对脱离实际、超越现实可能性的社会经济政策;主张道德源于生活,摈弃与生活严重脱节的虚骄的道德言行;坚持条件论,强调事物存在的现实性,强调人能有所为,但不能无所不为。孟子的条件论为其思想的务实精神,奠定了哲学基础。     

中小学生记忆组织的发展

本实验对中小学生记忆组织的年级差异和性别差异进行研究,全文分为两个部分：（１）中小学生词的记忆中客观组织（类的群集）的年级差异和性别差异;（２）中小学生词的记忆中主观组织的年级差异和性别差异．结果表明：（１）中小学生记忆中客观组织程度在逐渐提高,（２）不同年级中小学生对双字词记忆的主观组织程度是不同的;（３）Ｅ．Ｔｕｌｖｉｎｇ测定主观组织程度的方法在测定低年级学生记忆的主观组织程度时表现出很大缺陷．     

字距在视觉干扰中作用的实验研究

本研究分别以字距和刺激呈现的时序为变量,采用同一异匹配作业和视搜寻范型,通过两个实验论证,字距因素是导致语境产生视觉干扰的一种必要而充分的条件。     

Perceptual sampling of orthogonal straight line features

Summary Among mathematical models of visual confusion of letters and similar material, those that posit a feature detection process have been especially popular. The present study provides direct tests of several of the central assumptions of such models with feature-stimuli composed of the blank, one of two straight line features, or both line features positioned at a right angle. In one condition, the two features were connected when they appeared together, whereas in the other condition they were separated by a gap. A model which makes the strong assumptions that the features are sampled (detected) independently and then reported in a direct, unbiased fashion, performed acceptably in both conditions. Feature dependency models and those positing a biased decision process were ruled out on the basis of poor fits or lack of parsimony. The perceptibility (d) of a specific feature depended on the stimulus that contained it in the Gap condition but not in the Connected condition. The relative perceptibility of the horizontal vs in the vertical features was also different in the Gap vs Connected conditions. The results were compared with other recent studies, including ones in which sampling independence was falsified, apparently because of greater stimulus complexity, and employing a stimulus set that did not contain all possible combinations of features.We would like to thank J.T.
