不同科学创造力个体干扰抑制机制的比较*

选取《科学创造力量表》筛选出高、低科学创造力个体各20名,通过完成经典Stroop色字干扰抑制任务,探讨高、低科学创造力的个体抑制机制的差异。结果发现:在Stroop色字任务上,无论是高科学创造力组还是低科学创造力组,都出现了Stroop干扰效应,但低科学创造力组的Stroop效应更明显;高科学创造力组在字色不一致条件下的错误率显著低于低科学创造力组,但是两组被试在Stroop任务反应时上差异不显著。本研究结果提示高科学创造力个体的认知抑制能力强于低科学创造力个体。     

4-6岁儿童在小模型旋转任务中的线索学习与位置学习*

以90名4-6岁儿童为被试,探讨了儿童在小模型旋转任务中利用线索学习和位置学习表征空间位置的年龄特点。研究结果表明:(1)儿童对线索学习的利用要优于对位置学习的利用;(2)4岁儿童已经可以使用线索学习的方式表征空间位置,但到6岁左右才开始能够使用基于方向的位置学习;(3)线索特征对于儿童的线索学习有显著影响,明显、突出的线索有利于儿童的线索学习。     

遵守规范的动机对儿童过度模仿的影响

模仿非任务相关动作的行为被称为过度模仿。研究以94名4-6岁儿童为被试,通过操纵无关动作与结果之间的关系,考察了儿童遵守规范的动机对过度模仿的影响。结果发现,当遵守规范导致不能得到想要的结果时,儿童没有表现出明显的过度模仿;而当遵守规范与得到结果不冲突时,儿童过度模仿的比例显著增加。这些结果说明遵守规范的动机影响儿童的过度模行为,当遵守规范的动机降低时,过度模仿行为减少。     

模糊产品展示对产品态度的影响机制

本文基于关联习得理论, 探讨了模糊产品展示对产品态度的影响。结合4个实验的结果, 发现模糊产品展示对产品态度的影响呈现倒U型。相比于低模糊度的产品展示, 中等模糊度的产品展示能够激发更高水平的柔软度感知, 进而提升产品质量评价, 最终导致产品态度更积极。但过高模糊度的产品展示会激发消费者强烈的消极情绪, 消极情绪对产品态度的消极影响会抵消掉柔软度感知的积极影响, 最终导致产品态度的降低。     

条件推理的条件概率模型述评

该文从理论模型和实验范式两个方面对Oaksford等人提出的条件推理概率模型作了综合评述,并充分肯定该模型将演绎推理与归纳推理结合起来进行研究对推理心理学的发展所作出的重要贡献。     

养成训练:未成年公民品德塑造的新路径

重灌输轻养成、重理论教育轻行为训练是青少年道德建设成效不高的重要原因,而养成训练则被证明是未成年公民道德素质生成的有效路径.这是由品德生成的客观规律、未成年人身心发展的特点以及体验教育、实践育人的任务决定的.要切实提高道德行为习惯养成的实际效果,德目指标应易记易循,行为准则须明确具体;活动方案设计应贴紧未成年人实际,训练活动要注重可操作性,强化情感体验环节,抓好"小处"、"小事",注意训练活动的持续性和家校(园)之间的良性互动,不断巩固养成成果.实践证明,从基本道德行为习惯养成训练入手正是促进未成年人道德建设取得实效的关键所在.     

儒家中观经济论

一现存经济学理论的困扰与难题 作为哲学的一个部门或分支,"经济哲学"已受到学术界愈来愈多的关注与重视.然而,何谓经济哲学?在将历史上某种思想观念纳入经济哲学的视野中加以探讨时,首先面临的是"正名"的事情.本文将经济哲学理解为对于人类经济活动以及经济思想观念所做的"哲学探讨".从这种意义上说,它应当是"经济学"所赖以成立的基础.它要追问的问题其实有两个:(1)历史上人类所从事的经济活动的本性究竟如何?(2)经济学理论的主旨与目标究竟如何?故之,经济哲学其实既可以是"经济的哲学",又可以指"经济学的哲学",这正如所谓"历史哲学"既可以是"历史的哲学"(历史的形而上学),又可以是"历史学的哲学"(历史的认识论或"史学理论")一样.对于像经济哲学这样一门部门哲学来说,对人类经济活动的哲学反思与对经济学理论的哲学反思其实是难以截然分开的.因此说,它既是对于人类经济活动的反思,同时亦是对于人类经济思想观念(经济学理论)的反思.     

Measurement of self-evaluative motives: a shopping scenario

To develop measures of consumers' self-evaluative motives of Self-verification, Self-enhancement, and Self-improvement within the context of a mall shopping environment, an initial set of 49 items was generated by conducting three focus-group sessions. These items were subsequently converted into shopping-dependent motive statements. 250 undergraduate college students responded on a 7-point scale to each statement as these related to the acquisition of recent personal shopping goods. An exploratory factor analysis yielded five factors, accounting for 57.7% of the variance, three of which corresponded to the Self-verification motive (five items), Self-enhancement motive (three items), and Self-improvement motive (six items). These 14 items, along with 9 reconstructed items, yielded 23 items retained and subjected to additional testing. In a final round of data collection, 169 college students provided data for exploratory factor analysis. 11 items were used in confirmatory factor analysis. Analysis indicated that the 11-item scale adequately captured measures of the three self-evaluative motives. However, further data reduction produced a 9-item scale with marked improvement in statistical fit over the 11-item scale.     

Averaging to minimize or eliminate regression toward the mean to measure pure experimental effects

This paper explains how regression toward the mean can contaminate diary data, making it difficult to measure the pure effects of an experimental variable over time. Using a large scale real-life database collected by AT&T, a method of measuring this mathematical artifact is advanced. It is shown to manifest very quickly as a result of a spontaneous reaction toward happenstance, with the most extreme initial values gravitating most toward the mean. Then averaging over longer and longer periods of time to define use categories is shown to dilute happenstance increasingly, and therefore progressively minimizes or eliminates regression toward the mean. Finally, regression toward the mean is very pervasive and very persistent.     

Skin conductance as an indicator of anticipated concealed knowledge

The present study investigated the effects of anticipation on skin conductance while participants were answering a set of questions which included one of concealed knowledge. Two experiments were conducted. In Exp. 1, 26 participants completed one experimental session. Each participant was asked to choose one two-digit number from 10 to 99 and was presented 19 other randomly generated two-digit numbers. The list of numbers was then presented to the participant on a computer screen, with a 60-sec. interval occurring every two questions. The participant-selected number was defined as the target question which was randomly placed within the 4th to 17th item of 20 questions stated as follows: "Is your selected number?" The participant was asked to answer "No" to all questions. The skin-conductance response to each question was measured. In Exp. 2, the experimental procedure was the same as that in Exp. 1 except each participant first answered 10 nontarget questions, then answered a target question with the participant's selected number, and then answered another 10 nontarget questions. There were a total of 21 questions. Analysis indicated participants in both experiments generated the highest mean skin conductance while answering the target questions, followed by lower amplitudes to questions prior to and after the target question. The skin-conductance response pattern can be used to identify the psychological process of anticipation of concealed information.
