错误再认:意识、注意和刺激特性

该研究基于错误再认现象,确立了意识知觉和无意识知觉在行为结果上的质的差异。在决定一个刺激是被有意识知觉还是无意识知觉时,刺激特性和注意之间存在着相互补偿的作用。实验一表明,当一个刺激短暂呈现而被无意识知觉的时候,增强刺激特性或提高注意水平都能使它的知觉变为有意识的;相对应地,实验二表明,一个处于分散注意条件下被无意识知觉的刺激,也可以通过使注意集中或增强刺激特性而使它的知觉变为有意识的。该研究对意识、注意和刺激特性三者间的关系进行了讨论。     

Relative area and relative luminance combine to anchor surface lightness values.

The anchoring of lightness perception was tested in simple visual fields composed of only two regions by placing observes inside opaque acrylic hemispheres. Both side-by-side and center/surround configurations were tested. The results, which undermine Gilchrist and Bonato's (1995) recent claim that surrounds tend to appear white, indicate that anchoring involves both relative luminance and relative area. As long as the area of the darker region is equal to or smaller than the area of the lighter region, relative area plays no role in anchoring. Only relative luminance controls anchoring: The lighter region appears white, and the darker region is perceived relative to that value. When the area of the darker region becomes greater than that of the lighter region, relative area begins to play a role. As the darker region becomes larger and relative area shifts from the lighter region to the darker region, the appearance of the darker region moves toward white and the appearance of lighter region moves toward luminosity. This hitherto unrecognized rule is consistent with almost all of the many previous reports of area effects in lightness and brightness. This in turn suggests that a wide range of earlier work on area effects in brightness induction, lightness contrast, lightness assimilation, and luminosity perception can be understood in terms of a few simple rules of anchoring.     

认知老化模型的研究

以２３２名２０－７９岁成人为被试和５项认知能力测验为指标,应用结构方程建模方法建立了认知老化模型。     

通过样例和问题求解学习物理──加强对条件的认知

这项研究支持了我们先前的研究结果,即知识可以表征为一组产生式规则,产生式规则的学习可以通过考察样例和通过问题求解的方式进行。这项研究特别探讨了加强对于产生式的条件认知加工活动的效果。结果表明了我们这一构思的有效性。此外,还讨论了这一学习模式的学习过程。     

情绪表达性对人际关系的影响概述

在日常生活中情绪表达性指:人们交流体验的影响和影响人际关系的方式、个体对表达内容、表达方式、表达对象的选择,决定了他人会作出怎样的反应,并将对个体的人际关系产生影响。良好的人际关系有利于大学生形成和发展健康的个性品质,也有利于培养他们的合作精神。本文主要介绍了情绪表达和人际关系的部分研究概述和研究所使用的工具,为以后的研究打下基础。     

最后通牒游戏中接收者拒绝行为的情绪义务模型

公平偏好使人们在面对不公平的分配时通常会有所表示,在最后通牒游戏中具体表现为对不公平报价的拒绝,有很多研究把拒绝的原因归结为不公平厌恶和互惠主义等社会偏好,但这并不能解释一些最后通牒变体游戏中的拒绝行为。但这恰恰支持了情绪义务模型。     

大学生经济信心和心理健康的关系:生涯自我效能感的中介作用

采用经济信心问卷、生涯自我效能感量表、总体主观幸福感量表、贝克焦虑和抑郁量表,对237名大学生进行调查,考察大学生经济信心对其心理健康的影响,以及生涯自我效能感在两者之间可能的中介作用。结果表明,经济信心与生涯自我效能感和主观幸福感呈显著的正相关,与抑郁显著负相关,生涯自我效能感与主观幸福感显著正相关,与焦虑、抑郁显著负相关。大学生经济信心对其主观幸福感和抑郁具有显著的预测作用。大学生生涯自我效能感在经济信心与主观幸福感之间起到部分中介作用,其在经济信心和抑郁之间起到完全中介作用。此外,大学生生涯自我效能感传递了经济信心对焦虑的间接影响。     

Suicide method runs in families: a birth certificate cohort study of adolescent suicide in Taiwan

Suicide method used by adolescents was examined to determine if it was the same as that employed by their suicidal parents. Six hundred eighty adolescents completed suicide between 1997 and 2007, of whom 12 had parents who had previously died by suicide. The suicide method used by these adolescents was compared with that employed by their suicidal parent and that of a matched peer control adolescent with no exposure to parental suicide and living in the same area. In 10 of the 12 suicidal parent-adolescent dyads, the same suicide method was employed by parent and adolescent. Of seven adolescents whose age at parental suicide was 15 years or above, six used the same suicide method as their suicidal parent had. On the contrary, of 12 exposure-nonexposure suicidal adolescent dyads, the same method was used in only four. Adolescents exposed to parental suicide are more likely to use the suicide method employed by their suicidal parents than the method used by adolescent peers with no exposure to parental suicide.     

汉语儿童的语音加工技能与其单词朗读技能的关系研究

以121名小学五年级学生为被试,采用测验法,考察了汉语儿童的语音技工技能与其英文单词朗读技能的关系。结果表明:语音加工技能的三种成分均能够对英文单词朗读技能产生影响,其中,语音意识对单词朗读技能具有重要影响,快速命名能力和语音工作记忆也能够对单词朗读技能产生影响。     

智力落后儿童听觉注意的稳定性研究

本研究通过对智力落后儿童和正常儿童听觉注意稳定性的比较研究,探索智力落后儿童听觉注意稳定性的特点及影响因素。结果表明:4岁智龄组智力落后儿童听觉注意稳定性较弱,低于或等于同智龄组正常儿童水平。智力落后儿童慢速和快速情境下的注意稳定性高于中速。信噪比也影响注意的稳定性,信噪比越低,注意稳定性越差。频率因素对智力落后儿童的影响不显著。
