The intuitive personologist and the individual differences model

Subjects are required to estimate sociability as expressed in questionnaires supposedly completed by different individuals and make a prediction of conduct for each of these individuals. The results are compared to four models: three versions of the individual differences model (IDM) and a dialectical model. Two rudimentary versions of the IDM give the best approximations to results obtained, one for absolute value judgments of sociability, the other for conduct prediction. The conclusion is that the IDM does exist as a model in implicit psychology before becoming a model in learned psychology. The fact that such a model be preponderant in intuitive psychology in spite of its known inadequacies is discussed in terms of self-fulfilling prophecy in the exercise of power.     

儿童在数及数学上对部分与整体关系认识的发展

本文概括了九个有关数和数概念的实验研究结果。作者在最早的四个实验的基础上,提出了儿童对部分与整体关系认识的十二项指标,再以之通过正整数,几何图形和分数三个方面进行探讨,探讨结果由两个数学试验验证应用。根据研究总结果,作者讨论了揭示认识对象的内在规律对于主体认识活动的作用,部分与整体关系认识的年龄特点,阶段性及激进时期以及认识这个关系的心理过程。也对数的部分与整体关系的掌握对小学数学教学的应用提出了意见。     

关于汉字识别加工单位的研究

以眼动为指标的研究发现,汉字识别是以笔画为单位进行加工的。而词识别单位化模型则认为对熟悉词的识别与组成词的字母加工无关。本研究利用汉字具有笔画多少不同及组成部件不等的差别,以独体字或少笔画字为对照,通过三个实验探讨了高频和低频汉字识别的加工单位问题。实验结果表明,高频字笔画数和部件数分别对字识别产生显著影响,低频字似乎只有当笔画数和部件数两种成分都具有一定差异时才表现出识别速度的显著差别。此结果不支持前述的两种模型。提出汉字识别是由多种成分综合作用的结果似更合理。     

电损毁隔区对家兔探究反应的影响

本实验观察电损毁家兔隔区对新异刺激的探究反应的影响。实验结果表明:损毁隔区的动物对新异刺激作用时脑皮层电图(ECoG)惊醒反应的出现率,在皮层与海马都明显低于对照组,与损毁海马动物的特点一致。作者对这一实验结果进行了讨论。     

对语义网络中概念非类属关系的实验研究

本研究包括三个实验。实验一在混和呈现条件下比较被试对隐喻句和类属句的加工时问,发现可理解性高的隐喻句的R_T不比类属句的慢。实验二在分组呈现条件下比较被试加工隐喻句与类属句的速度,结果与实验一基本相同。实验一、二中还发现类属概念的层次与语义加工时间没有必然联系。实验三比较了隐喻句对三类概念的启动作用,发现隐喻对自身的语义特征概念有明显的启动作用。根据三个实验的结果,我们提出了一种称为特征联结的语义网络结构模型。     

如何利用广义量词的语义性质判断扩展三段论的有效性

在国内外最新研究成果的基础上,笔者通过对文中的定理和推论的证明,主要说明了以下几点：（1）利用广义量词的相关语义性质,比如单调性和对称性,既可以解释亚氏三段论的有效性,又可以解释带有广义量词的扩展三段论的有效性;（2）一些有效的扩展三段论仅仅表征了广义量词的左或右单调性,还有一些有效的扩展三段论同时表征了广义量词的多个语义性质;（3）利用广义量词的东南或西北或西南或东北方向的单调性可以判断一些带有限制条件的扩展三段论的有效性。此研究将有利于广义量词理论的发展,对于计算机科学中的知识表示和知识推理的研究都具有较为重要的理论价值和实践意义。     

Virtual/real transfer of spatial knowledge: benefit from visual fidelity provided in a virtual environment and impact of active navigation

The purpose of this study was to evaluate the effect the visual fidelity of a virtual environment (VE) (undetailed vs. detailed) has on the transfer of spatial knowledge based on the navigation mode (passive vs. active) for three different spatial recall tasks (wayfinding, sketch mapping, and picture sorting). Sixty-four subjects (32 men and 32 women) participated in the experiment. Spatial learning was evaluated by these three tasks in the context of the Bordeaux district. In the wayfinding task, the results indicated that the detailed VE helped subjects to transfer their spatial knowledge from the VE to the real world, irrespective of the navigation mode. In the sketch-mapping task, the detailed VE increased performances compared to the undetailed VE condition, and allowed subjects to benefit from the active navigation. In the sorting task, performances were better in the detailed VE; however, in the undetailed version of the VE, active learning either did not help the subjects or it even deteriorated their performances. These results are discussed in terms of appropriate perceptive-motor and/or spatial representations for each spatial recall task.
