学前儿童对事实、信念、愿望和情绪间关系的认知

76名3至5岁儿童接受了区分事实和信念、根据信念推测他人愿望、根据愿望推测他人情绪等实验任务,通过考查学前儿童对事实、信念、愿望和情绪间关系的认知,探察学前儿童心理理论发展的特点。结果显示3岁儿童在区分信念和事实时,出现错报事实或错报信念两种错误,而不单纯是现实主义偏向错误;在推测他人愿望时,部分3岁和4岁儿童虽然能够正确报告他人的信念却不能正确推测他人愿望,愿望认知发展有其复杂性的一面。学前儿童主要依据愿望推测他人情绪,儿童对信念和愿望的认知水平制约儿童对他人情绪的理解。     

Mood and flexibility in categorization: a conceptual replication

The present study tested the hypothesis that positive mood facilitates cognitive flexibility in categorization, i.e., positive mood enhances the ability to categorize flexibly at broad and narrow levels contingent on task requirement. The study was a conceptual replication of the 1990 work by Murray, Sujan, Hirt, and Sujan. Unlike the original study, it was carried out on the WWW with some modifications in the procedure. Participants were 29 women and 132 men whose average age was 29 yr. They were put into a positive, negative, or neutral mood using the Velten technique. Mood was measured with standard mood scales. Subjects then listed similarities differences between two entertainment TV shows. Contrary to the prediction, participants in a positive mood did not list a higher number, more diverse, or more unusual similarities and differences between the shows, and they were not faster than participants with neutral or negative moods. It is concluded that the influence of mood on cognitive flexibility needs to be reconsidered. In research, temporal aspects of categorization performance as well as a wider range of mood valences should be taken into account.     

First-Pass versus Second-Pass Parsing Processes in a Wernicke''s and a Broca''s Aphasic: Electrophysiological Evidence for a Double Dissociation

The present paper is a first attempt to integrate the classical brain lesion behavioral impairment approach of functional neuroanatomy and the electrophysiological brain mapping approach in the domain of syntactic processing. In a group of normal age-matched controls we identified three electrophysiological components previously observed in correlation with language comprehension processes: an early left anterior negativity normally seen in correlation with syntactic first-pass parsing processes (ELAN), a centroparietal negativity seen in correlation with processes of lexical-semantic integration (N400), and a late centroparietal positivity observed in correlation with secondary syntactic processes of reanalysis and repair (P600). The early left anterior negativity was absent in a patient with an extended lesion in the anterior part of the left hemisphere sparing the temporal lobe, although the late centroparietal positivity and the centroparietal N400 were present. In a patient with a left temporal-parietal lesion the early left anterior negativity was found to be present, whereas the N400 component was absent. These findings suggest that first-pass parsing and secondary processes are subserved by distinct brain systems.     

性别加工的记忆效应与内隐性别刻板印象

本研究以72名在校大学生为被试,采用心理过程分离程序,探讨了不同性别加工学习条件下被试的记忆效果。实验结果表明：在两性角色行为特征的认知过程中,意识过程和无意识过程对记忆效果的影响是不同的。有意识的外显记忆效果,两种条件无显著差异;但在无意识的内隐记忆效果上差异显著,反映了一种对女性另眼相看,严格苛求的内隐性别刻板印象。     

不同反应方式对双作业操作信息干扰的影响

本研究采用单作业双作业操作,探讨了不同反应方式对双作业操作信息干扰的影响。实验结果证明;若采用相同的反应方式,同时操作的两种作业就会产生相互干扰,降低作业绩效;相反,若采用不同反应方式将减小双作业操作的相互干扰,提高双作业操作绩效。     

学前儿童对短时时距的区分及其认知策略

本研究以令儿童比较时距长短为手段进一步探查学前（５、６岁）儿童对短时时距的认知过程,挖掘幼儿的认知潜力。研究结果表明：１）学前５、６岁儿童已能区分只有几秒钟差异的短时时距;２）６岁儿童已能使用时间标尺测量时间,５岁儿童已有潜力把时间看成是可以计数的维量;３）两时距的时间差别大小是影响儿童认知成绩的主要因素之一。     

The effects of incorrect pain expectations on acquired fear and pain responses

Previous experimental research on the effects of incorrect intensity expectations of aversive events can be criticized because intensity expectations were not manipulated independently from changes in objective intensity. The present study aims at investigating the effects of incorrect intensity expectations on the immediate and later responses to a painful stimulus, and on the acquisition of anticipatory responses, with proper experimental control. Subjects (n = 62) received 20 painful stimuli of varying intensity. In the control group intensities were correctly signalled on all trials by an analogue signal. On 3 trials the signal was too large in the overprediction condition, and too small in the underestimation condition. Underpredicted painful experiences were related to subsequent higher pain responses on the physiological level, but not on the subjective level; and to increased anticipatory responses (increased pain expectations, uncertainty, subjective fear, skin conductance responses). Skin conductance level also indicated increased fear after underpredicted experiences. Overpredicted painful experiences were related to a faster decrease in subjective fear compared to the control group, but did not influence other variables. The findings support the notion that underpredictions contribute to the acquistion of fear and disrupt habituation processes. The asymmetrical processing of the two kinds of incorrectly predicted experiences is discussed.     

4.5—7.5岁儿童对年龄认知发展的实验研究

本研究探讨儿童对年龄认知发展的过程和特点。主要结果表明:(1)在呈现刺激数量相等的条件下学前儿童对年龄时序相对可变性的认知成绩低于对相对固定性的认知,对前者的认知表现出学龄前、学龄后两个明显的发发阶段;(2)学前儿童对出生次序的认知成绩低于对年龄大小的认知成绩;(3)儿童对年龄将来时的认知表现出由近及远、由短及长的发展趋向。     

中学生阅读动机与阅读时间、阅读成绩的关系研究

采用问卷调查法对３５３名初、高中学生的阅读动机、阅读时间及阅读成绩进行了调查,结果发现：１．中学生的阅读动机是多维度的,包括内部动机、外部动机、社会性动机与自我效能,它们之间相互影响、相互联系;２．中学生阅读动机水平的高低与阅读时间、阅读成绩存在极为显著的正相关,其中,内部动机对中学生阅读时间、阅读成绩的影响要大于其它因素的影响;３．中学生的阅读动机发展特点具有性别帮年级差异,趋势是初中生优于高中     

Effects of intergroup contact and relative gratification vs. deprivation on prejudice on both sides of the U.S./Mexico status divide

A study in the U.S.–Mexican intergroup context examined how collective relative gratification (RG) versus deprivation affects the relationship between intergroup contact and interpersonal closeness and subtle prejudice towards an out-group. Participants were Mexican university students in Mexico (N = 239) and non-Mexican students in California (N = 90). As predicted, Mexicans experienced less gratification/higher relative deprivation (RD), and low quality intergroup contact and expressed lower interpersonal closeness and higher subtle prejudice than U.S. Americans. Differences between countries were larger amongst participants reporting higher RD. Second-stage moderated mediation analysis showed that the mediating effects of contact between country and interpersonal closeness and subtle prejudice, respectively, were larger amongst participants who felt relatively gratified than those who felt relatively deprived. These findings underline the importance of recognizing the moderating effect of differences in the RG versus RD levels of minority and majority groups when anticipating the potential benefits of intergroup contact for prejudice reduction.
