行为决策中出现的分离效应

分离效应（the disjunction effect）是指：当决策者知道事件E会发生,他会采取行动A;当知道事件E不会发生,他仍会采取行动A;而当不知道事件E是否会发生的情况下,他会拒绝行动A。这一现象违背了理性决策理论的确定事件原则（sure-thing principle）。对分离效应的解释主要有基于理由的假设、思维惰性假设和齐当别模型。分离效应是否真的存在以及应该采用何种实验设计来进行研究都还有待进一步探讨。2005年诺贝尔经济学奖获得者Aumann对事件分离情境和事件非分离情境的区分,为进一步研究分离效应指明了新的方向。理解分离效应及其成因有利于人们做出“理性”的决策     

发展中的行为决策研究

行为决策研究人们如何进行判断与选择。该学科希望能在描述决策的过程中帮助人们更好地进行决策,其研究的使命是促进和改善我们对人类决策行为的理解。在过去的1年里,中国科学院心理研究所行为决策课题组在社会与经济决策领域中已开展的研究包括：行为决策与脑、社会互动与决策、决策的文化差异、消费与投资的行为决策、效用最大化与幸福感。该文着重报告并讨论了我们在行为决策及其跨文化比较研究中的一些最新的主要发现

情绪状态对学生创造性的影响

研究了情绪状态对学生创造性影响的问题。被试为上海师范大学第三附属中学初二的学生 2 2 0名 ,其中男生 10 4人 ,女生 116人 ,年龄 13～ 14岁。由于国外已有研究的结果并不统一 ,研究的方法也缺乏生态化效度 ,因此本文试图通过教学现场实验 ,运用实际教学情境中的刺激来诱发学生愉快—难过情绪 ,以探索在教学情境中学生情绪状态对其创造性影响状况。研究结果表明 ,学生在愉快情绪状态下的创造性总体发挥水平显著高于难过情绪状态 (t=2 0 2 5 ,p =0 0 4 5 ) ,且主要体现在流畅性和变通性两个方面     

Lexical activation during the recognition of Chinese characters: Evidence against early phonological activation

In two primed-naming experiments involving Chinese character recognition, one with native Mandarinspeaking subjects and another with native Cantonese-speaking subjects, we varied both the stimulus onset asynchrony (SOA) and the prime—target similarity along various lexical dimensions. Across both experiments, the results were as follows: (1) Relatively strong and reliable semantic priming appeared very early across various SOAs, and its onset was not affected by meaning precision, (2) either homophonic priming had negligible effects on target naming or the effects appeared relatively late (only at 57 msec), and (3) graphic inhibition was found across different SOAs. Since the same set of stimuli and procedure were adopted as those in the study of Perfetti and Tan (1998), the present findings raise questions about the reliability and validity of the results from their study that have been used to support the notion that phonology is a constitutive element of character recognition and precedes meaning access in the identification process. Instead, the present results suggest that phonology is optional for accessing meaning in Chinese character recognition among skilled adult readers.     

The Eight Trigrams of the Chinese I Ching and the Eight Primary Emotions

Durkheim and Mauss, in Primitive Classification , concluded that the emotions play a causal role in the history of dual symbolic classification systems, but could not test this intuitive speculation because they saw a classification of the emotions as impossible. In this paper a portion of Plutchik's psychoevolutionary model of the primary emotions are assumed to be valid and are then investigated through analysis of one of their three case studies of primitive classification, that of classification in ancient China, where their emphasis was on the eight "trigrams" or "powers" that they saw arranged in a "divinatory compass." The trigrams are three-line components of the "hexagrams," the six-line figures that are interpreted as master signs in I Ching divination rituals. Using Plutchik's psychoevolutionary classification of the emotions as a basis of comparison, especially his model of the primary emotions as adaptive reactions to the positive and negative experiences of four existential problems – identity, temporality/reproduction, hierarchy, and territoriality – it is found that both trigrams and primary emotions exist as four pairs of opposites. The eight trigrams and eight primary emotions similarly can be seen as adaptive reactions to the four basic problems of life. Through structural analysis, correspondences between the trigrams and the primary emotions are developed, the result being that the primary emotions are structurally isomorphic and very close in first meanings to the primary attributes of the trigrams. Implications of this isomorphism of structure for the development of a social psychology of the emotions are discussed.     

维-汉-英三语者三种语言语义通达模型的实验研究

以维吾尔族大学生为研究对象,采用跨语言启动条件下的真假词汇判断任务,变换启动词与目标词的关系类型和语言种类,考察了L2—L1、L3—L1、L3—L2等三种语言词汇之间的语义通达模式。结果发现,维-汉-英三语者的三种语言词汇之间的联结模式为熟练的第二语言词汇是直接通达语义;而非熟练的第三语言词汇既借助母语词汇又借助汉语词汇来通达语义。除此之外,被试的外语熟练水平和语言间的相似性是影响外语词汇通达语义的主要原因。     

3～9岁儿童人格特质稳定性理解的发展特点

采用情境故事法对281名3～9岁儿童对不同类型的消极或积极特质稳定性的理解进行了个别测查,使用了“性质-类型-性质”的特质推理研究范式,任务涉及跨时间稳定性和跨情境一致性两个层面的考察。五因素重复测量方差分析结果表明,3～9岁儿童对于特质稳定性的理解表现出随年龄发展稳定观不断增强的趋势,4岁可能是儿童特质稳定性理解由不成熟向成熟方向发展的关键点;此外,研究验证了年龄与特质性质的交互作用,也发现了问题类型和特质类型对特质稳定性理解的调节作用。这些特点与年幼儿童获得的心理知识和对特质发展影响因素的觉知有关,也可能与整个文化系统的直接或间接作用有关。
