国外关于情绪与记忆的理论与实验研究综述

文章简要介绍了国外有关情绪与记忆的相关理沦,以及与之有关的实验研究。近年来,情绪对于人类理性认知活动的建设作用正逐步受到人们的重视,尤其是情绪对记忆影响的研究一度成为热点,有关情绪与记忆的理论相继产生。这里主要介绍四个有关情绪与记忆的理论。     

情绪、边框影响决策认知过程的实验研究

借用问题空间,通过实验探讨情绪、边框对决策认知过程的影响,以进一步考察边框效应的本质特点。结果如下：情绪、边框均独立对决策认知过程产生影响;积极、消极信息导致不同的加工方式;积极信息既利于节省认知资源,又利于作出符合当前环境的决策。     

Emotion Specificity and Consumer Behavior: Anger, Sadness, and Preference for Activity

We examine the influence of two specific negative emotions (i.e., sadness and anger) on consumers' preference for an advertised product promoting either activity (e.g., exercise) or passivity (e.g., relaxation). On the basis of empirical distinctions between the level of activation accompanying sadness and anger, and drawing upon a mood-as-information perspective, we hypothesized that individuals will have a preference for activity to passivity when in an angry compared to a sad emotional state. Thus, when angry, they preferred a product advertised as active, whereas when sad they preferred a product described in more passive terms.     

'The double identity' of Taiwanese Chinese: A dilemma of politics and culture rooted in history

The 'double identity' of Taiwanese as both Chinese and Taiwanese identity was measured among both general and student samples using categorical and continuous measures. As predicted, Mingnan (native province) Taiwanese were higher in Taiwanese identity whereas outside-province Taiwanese were higher in Chinese identity. Both groups shared similar representations of the history of Taiwan, but evaluations of leaders followed patterns of in-group favoritism. These representations of history were used to predict and find zero correlations between Chinese and Taiwanese identity. Taiwanese and Chinese identities were mutually compatible in cultural domains, and mediated the effect of demographic group. However, in issues concerning politicized allocation decisions (and language), Taiwanese and Chinese identity worked in opposite directions, and demographic group (and a critical evaluation of an historical leader) were significant even after controlling for identity. Implications for social identity theory, realistic group conflict theory, and the cross-straits relationship are discussed.     

Person perception in the heat of conflict: Negative trait attributions affect procedural preferences and account for situational and cultural differences

Disputes by their nature involve contentious behavior. If one attributes such behavior to underlying personality traits, these attributions can be quite damning. The current research investigated negative trait attributions and their impact on dispute resolution decisions. We hypothesized that judging one's opponent to be low in agreeableness and high in emotionality (e.g. stubborn and volatile) shifts one's preference towards more formal procedures – formal in the sense that a third party judge controls the process and outcome. Drawing on the attribution literature, we hypothesized that two antecedents of these judgments (and consequent preferences) are the perceiver's level of prior information and the perceiver's cultural proclivity to explaining behavior in terms of personal dispositions. Results of an experiment measuring reactions to a hypothetical dispute found that prior information and culture (USA vs Hong Kong) increased trait attributions and preferences for formal procedures. Additionally, expectancy measures showed interaction effects suggesting that disputants dynamically construct expectancies in light of their personality impressions.     

What is it to move oneself emotionally? Emotion and affectivity according to Jean-Paul Sartre

Phenomenology and the Cognitive Sciences - Emotion is traditionally described as a phenomenon that dominates the subject because one does not choose to be angry, sad, or happy. However, would it be...     

内隐学习研究方法述评

内隐学习自提出以来就成为认知心理学研究的热点,近40年内隐学习领域的研究在本质上都基于几种经典的研究方法和实验逻辑。本文拟对这些代表性的内隐学习研究方法做系统的介绍和归纳。     

情绪启动与语义启动的比较

情绪启动与语义启动发生时孰先孰后、进行中独立平行还是交互作用、效应上孰强孰弱,还存在较大争议.这些争议的本质涉及到人脑中情绪和认知这两大基本系统的关系认识问题.通过行为观察与事件相关脑电位技术结合,在同一个实验中设置情绪启动、语义启动两种情境,并匹配可能影响这两种启动效应的因素,如信息强度、启动刺激和靶刺激的信息关联程度等,然后系统性变化启动刺激呈现的时间、SOA、实验任务等,并逐步加入被试的年龄、性别、学科专业、认知风格、情绪易感性等个体差异变量,可望直接而系统地澄清争议,深层次揭示情绪信息流与语义信息流的加工特点,并进而揭示人脑情绪系统与认知系统功能与机制的发展规律.     

中等强度情绪性图片的神经机制——一项fMRI研究

采用修订后的中等唤起度的国际情绪图片为刺激材料,以12名女性大学生为被试,考察情绪性图片引起的脑激活模式。结果发现,与中性条件相比,消极情绪图片激活了枕叶、杏仁核、海马旁回和壳核。积极情绪图片引起枕叶、内侧眶额、额中回等脑区的激活,研究结果再次验证了杏仁核与消极情绪的密切关系,同时推测,内侧眶额可能是中等唤起度的趋近性积极情绪的一个脑功能区。     

刻板印象激活效应对社会分类的影响

采用改进的flanker范式,探讨了刻板印象激活效应对社会分类的影响,并考察了匹配刺激出现概率对刻板印象激活效应影响社会分类的调节作用。实验一发现,性别刻板印象激活后,按性别分类时,匹配刺激中和不匹配刺激中面孔分类反应时之间的差异是显著的,但按年龄分类时,二者间的差异不显著。实验二表明,匹配刺激出现概率为80%时和50%时,匹配刺激中和不匹配刺激中面孔分类反应时之间的差异是显著的;但当匹配刺激出现概率为20%时,二者间的差异不显著。结果表明,刻板印象激活效应对与该刻板印象对应的社会分类有显著的影响,对与该刻板印象无关社会分类不会产生影响。刻板印象激活效应对社会分类的影响受匹配刺激出现概率的调节。
