Previous research has shown a widespread bias among Hong Kong adolescents against Chinese Mainlanders. Based on social identity and social cognitive theories, we examined the effects of identity frame switching (situational induction of social category inclusiveness) and time pressure (environmental constraints on social information processing) on Hong Kong adolescents' attitudes toward Chinese Mainlanders. Results indicated that Hong Kong adolescents had acquired a habitual tendency to make social comparisons within an exclusive regional framework of reference. This habitual tendency might lead to negative judgment biases toward Chinese Mainlanders, particularly when the adolescents made social judgments under time pressure. In addition, switching to an inclusive national frame of reference for social comparison attenuated negative intergroup attitudes. The theoretical implications of these findings are discussed. 相似文献

Robert Rosen has proposed several characteristics to distinguish “simple” physical systems (or “mechanisms”) from “complex”
systems, such as living systems, which he calls “organisms”. The Memory Evolutive Systems (MES) introduced by the authors
in preceding papers are shown to provide a mathematical model, based on category theory, which satisfies his characteristics
of organisms, in particular the merger of the Aristotelian causes. Moreover they identify the condition for the emergence
of objects and systems of increasing complexity. As an application, the cognitive system of an animal is modeled by the “MES
of cat-neurons” obtained by successive complexifications of his neural system, in which the emergence of higher order cognitive
processes gives support to Mario Bunge’s “emergentist monism.”

Brain training is increasingly popular, and many believe in the efficacy of such programs without empirical evidence. We examined whether instructions promising memory improvement would influence subjective and objective cognition. Participants (n = 145; age: M = 50.64) were randomly assigned to a memory improvement or memory task condition. Participants completed demographic and perceived control over cognition measures, in addition to cognitive tasks and subjective cognition items for 7 days. Participants in the improvement condition reported significantly greater memory increases than those in the memory task condition. This effect was moderated by perceived control over cognition; participants in the improvement condition with high control beliefs were significantly more likely than those with low control beliefs or those in the task condition to report better memory. Individuals with higher control beliefs may be more susceptible to the claims of brain training programs, which is significant given that such programs are increasingly popular and commercially available. 相似文献

In three studies we examined the willingness to support action to remedy a public problem. In Study 1 and Study 2, people were asked whether they would financially contribute to solution of a public problem. In Study 3, people were asked whether they would sign a petition to support a public action. The aim was to test whether the willingness to support solution of a public problem is affected by the type of problem that is used as the referent. We hypothesized that the willingness to support a public action is lower when evaluated in the context of a high‐ as opposed to a low‐importance referent problem (importance contrast effect). We also hypothesized that the importance contrast effect is tied to the perceived relatedness between the target and referent problems. The importance contrast effect should be found only when the two problems relate to different category domains. The findings bear out this prediction. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

The purpose of the present study was to assess the navigational behaviour of adult humans following a disorientation procedure
that perturbed their egocentric frame of reference. The assessment was carried out in a virtual reality (VR) environment by
manipulating the disorientation procedure, the retention interval, the relative positions of target and landmark. The results
of experiment I demonstrated that adding a physical rotation to a virtual disorientation procedure did not yield an additional
decrease in searching performance. The results of experiment II showed that shortening the delay between study and test phase
decreased the errors more markedly for geometric than landmark ones. An orientation specificity effect due to the manipulation
of the relative position between target and landmark was discussed across the experiments. In conclusion, VR seemed to be
a valuable method for studying human reorientation. Moreover, the virtual experimental setting involved here promoted knowledge
of the relationship between working memory and spatial reorientation paradigm. 相似文献

Kormi-Nouri, Moniri and Nilsson (2003) demonstrated that Swedish-Persian bilingual children recalled at a higher level than Swedish monolingual children, when they were tested using Swedish materials. The present study was designed to examine the bilingual advantage of children who use different languages in their everyday life but have the same cultural background and live in their communities in the same way as monolingual children. In four experiments, 488 monolingual and bilingual children were compared with regard to episodic and semantic memory tasks. In experiments 1 and 2 there were 144 boys and 144 girls in three school groups (aged 9-10 years, 13-14 years and 16-17 years) and in three language groups (Persian monolingual, Turkish-Persian bilingual, and Kurdish-Persian bilingual). In experiments 3 and 4, there were 200 male students in two school groups (aged 9-10 years and 16-17 years) and in two language groups (Persian monolingual and Turkish-Persian bilingual). In the episodic memory task, children learned sentences (experiments 1-3) and words (Experiment 4). Letter and category fluency tests were used as measures of semantic memory. To change cognitive demands in memory tasks, in Experiment 1, the integration of nouns and verbs within sentences was manipulated by the level of association between verb and noun in each sentence. At retrieval, a recognition test was used. In experiments 2 and 3, the organization between sentences was manipulated at encoding in Experiment 2 and at both encoding and retrieval in Experiment 3 through the use of categories among the objects. At retrieval, free recall or cued recall tests were employed. In Experiment 4, the bilingual children were tested with regard to both their first and their second language. In all four experiments, a positive effect of bilingualism was found on episodic and semantic memory tasks; the effect was more pronounced for older than younger children. The bilingual advantage was not affected by changing cognitive demands or by using first/second language in memory tasks. The present findings support the cross-language interactivity hypothesis of bilingual advantage. 相似文献

当前概率类别学习中主要存在多系统和单系统两种观点之争, 而持不同观点的研究者在其实验中分别采用了不同的线索位置呈现方式, 因此本研究采用经典的天气预测任务通过操纵线索位置的呈现方式来进一步探讨其对概率类别学习的影响。本研究包括2个实验:实验1考察所有线索位置固定和随机对概率类别学习系统的影响; 实验2通过单线索模式下线索位置固定考察概率类别学习的策略。结果发现, 当所有线索的呈现位置固定时, 概率类别学习是外显学习; 而当所有线索的呈现位置随机时, 概率类别学习是内隐学习; 而当只在线索单独出现时固定其位置, 概率类别学习仍是内隐学习。结果表明, 线索位置的不同呈现方式会影响概率类别学习中外显和内隐学习系统的竞争, 研究支持了多系统观点, 且概率类别学习的主要策略可能是多线索策略而不是单模式策略。 相似文献
