恒河猴数相加能力的初步研究

本实验训练恒河猴对两组其和不超过8的刺激实体(卡片上的黑色圆点)进行相加,再与第三组刺激实体进行数多少的比较判断。实验共有9个训练程序,课题逐次由易到难,刺激的数目也由少到多。有一只恒河猴达到了全部9个程序的训练标准。证明恒河猴的确具有学会把两个数进行相加的能力。这种相加不可能是数数的结果,极可能是在知觉上将它们融合或接合在一起。     

学习困难儿童的神经心理研究

本研究用中国修订的HR成套神经心理测验(HRB(m)-RC)、韦氏儿童智力量表(WISC-CR)、韦氏记忆量表(WMS-RC)和分类测验测查9—14岁学习困难儿童和正常儿童各50名。研究了学习困难儿童的神经心理特点和神经心理功能与学习成绩的关系,从神经心理学角度来讨论学习困难的教育干预。     

儿童运动行距预测能力的发展及影响因素

采用计算机软件控制实验,以三种不同运动速度、四种不同运动行距组合呈现的光点运动为刺激物,每次光点在暴露运动一段行程后进入遮蔽,要求儿童判断光点到达目标位置时按键反应。主要结果表明：（１）儿童运动行距预测能力的发展表现为５─８岁和１２─１９岁两个加速期及８─１２岁一个过渡期的发展模式。但在过渡期内,儿童的预测误差偏向有显著变化;（２）客体运动速度对儿童运动行距预测操作精度有显著影响,慢速下精度较高;（３）客体运动行距、被试性别并不影响儿童的行距预测操作;（４）５岁、１２岁与１９岁儿童多倾向于超前反应。     

遮挡范式下对碰撞时间的估计

本文研究视觉信息对碰撞时间估计的影响。实验采用遮挡范式（ｏｃｃｌｕｓｉｏｎ ｐａｒａｄｉｇｍ）,遮挡一段固定的距离,让被试估计该段距离所用的时间。自变量为移动速度与挡板的宽度。过程：让被试看速度知觉仪上移动的红灯,估计碰撞发生时按下电键。结果表明,移动速度对时间估计的准确性影响显著,速度越大,估计准确性越高;移动速度还与挡板宽度存在交互作用,即速度快、挡板宽度时碰撞时间的估计更准确,而速度慢、挡板     

呈现方式与认知方式对文章标记效应的影响

采用纸笔呈现和视频显示终端(video display terminab,VDT)呈现两种形式,探讨了认知方式与文章标记类型对文章阅读效果的影响,结果表明: (1)文章标记对不同认知方式的读者影响不同,无论有无文章标记,场独立者对各类信息的保持量没有明显的变化,而文章的宏观标记能够使场依存者的阅读指向发生改变,场依存者会更加注意与标记有关的内容; (2)呈现方式对文章信息的保持量有显著的影响,纸笔呈现方式下,被试的信息保持量明显好于VDT呈现方式; (3)在VDT呈现条件下,场独立者对主题性信息的保持量显著高于场依存者.     

浅论政治文明对实现社会和谐的重要意义

任何社会都不同程度地存在着社会矛盾和冲突,社会和谐就是通过一定的机制,使这些矛盾和冲突的强度与范围都得到有效调节和控制。本文在对中外思想家有关调节社会冲突的学说进行简要分析的基础上,论证推进政治文明建设,健全民主和法制,是调节社会冲突、实现社会和谐的一条基本路径。     

学习者控制和任务难度对多媒体学习的影响

使用两因素被试间设计探索在不同任务难度条件下单一的学习者控制—步调控制对120名大学生多媒体学习的影响。结果发现:(1)在复杂任务条件下,学习者控制组的再认成绩显著高于程序控制组;学习者对简单任务的主观难度感知显著低于复杂任务。(2)在学习者控制组,在学习复杂材料时,使用了控制选项的学习者其迁移成绩显著高于没有使用的学习者;但对控制的使用与否对简单任务的学习迁移成绩没有显著影响。本研究的结果表明,学习者控制可以促进大学生对比较复杂学习内容的记忆,对学习者控制的实际使用可以促进大学生对复杂内容的理解和迁移。学习任务难度在学习者控制影响多媒体学习效果中起调节作用。这一结论对多媒体学习设计具有重要启示。     

Need for uniqueness as a mediator of the relationship between face consciousness and status consumption in China

Strong economic development in China has led to a surge in status consumption as a means of gaining face. In Eastern culture, people interpret uniqueness as status distinction rather than separateness or deviance. This type of uniqueness can be used to meet others' expectations and gain social approval. Thus its relationship with face consciousness and status consumption is to be expected. This study investigates 2 hypotheses: (a) Face consciousness has a positive effect on status consumption and (b) Consumer need for uniqueness mediates the relationship between face consciousness and status consumption. Two‐hundred and forty‐six working respondents in eastern China completed a survey. Regression analysis of the results supported both hypotheses.     

Response readiness modulates the development of association-based automaticity in masked priming

The current study investigated the role of the automatization of stimulus and response (S-R) associations and response readiness in triggering the motor activation for masked primes in two experiments. The automatization of associations was manipulated by employing different types of stimuli, and response readiness was manipulated by varying the relative frequency of Go trials in a modified Go/No-Go task. Compatibility (compatible and incompatible), stimulus type (arrows and parallel lines), and test session (Sessions 1, 2, and 3) were manipulated in a high response-readiness condition (Experiment 1) and in a low response-readiness condition (Experiment 2). Negative compatibility effects (NCEs) occurred regardless of session and experiment in the arrow stimuli condition. However, in the parallel-line stimuli condition, no significant compatibility effect (CE) appeared regardless of the experiment in Sessions 1 and 2, whereas a significant NCE appeared in Experiment 1 but not in Experiment 2 in Session 3. These results are consistent with the claim that motor activation can only occur if the association between specific stimuli and specific responses has been automatized by previous practice, and response readiness can modulate the development of automaticity, but this modulation will have a minimal effect once the association is automatized. The findings also provide experimental evidence for the assumption that the formation of association-based automaticity could be modulated by top-down control (e.g., response readiness).     

论道义论与功利论的一个根本区分:正当与善何者优先

道义论与功利论是当代西方规范伦理学的两种基本理论形态.两者的区分可以以正当与善何者优先来界定.一般来说,强调正当优先于善,并不以善来界定正当的理论是道义论理论,而以善优先于正当,并以善来规定正当的理论是功利论理论.
