领导者上行影响力策略与工作绩效的关系研究

本文首先基于Schriesheim等人提出的上行影响力策略结构模型,修订和编制了领导者上行影响力策略量表,经探索性因素分析和验证性因素分析表明,上行影响力策略结构的一阶六因素模型是合理的;修订后的Schriesheim量表具有较好的信度和效度.然后采用修订后的量表对重庆市220名处级干部进行调查,并考察领导者上行影响力策略与工作绩效的关系.结果表明,上行影响力策略的利益交易和越级诉讼两因素对总体工作绩效及其任务绩效因素有显著的负向影响;上行影响力策略中的联盟因素对总体工作绩效及其任务绩效因素有显著的正向影响.     

类别学习中分类学习与推理学习的对比研究

本研究对类别学习中分类学习与推理学习进行了对比.实验中要求被试从成对呈现的项目中选择一个更典型的A,并且要求被试将典型的A和典型的B画出来.测试中所呈现项目诊断性程度或典型性程度不同.研究结果表明,分类学习者主要受诊断性信息的影响,而推理学习者主要受典型性信息的影响.即,分类学习者关注类别间信息,而推理学习者关注类别内信息.     

The cultural shaping of depression: somatic symptoms in China, psychological symptoms in North America?

The expectation that Chinese people present distress somatically is a central prediction of cultural psychopathology and has been the subject of considerable theoretical speculation. At the same time, empirical studies have been infrequent and have yielded mixed results. The authors examined symptom presentation in Chinese (n=175) and Euro-Canadian (n=107) outpatients, using spontaneous problem report, structured clinical interview, and symptom questionnaire methods. All 3 methods yielded cross-culturally equivalent somatic and psychological symptom subscales. Chinese outpatients reported more somatic symptoms on spontaneous problem report and structured clinical interview compared with Euro-Canadians, who in turn reported more psychological symptoms on all 3 methods. The relation between culture and somatic symptom presentation was mediated by a tendency toward externally oriented thinking. Difficulties with identifying emotions or describing them to others did not differ significantly across cultures, supporting a nonpathological interpretation of observed differences. Psychological symptom effects were larger and more consistent than somatic symptom effects; because other studies have confirmed the ubiquity of somatic presentations worldwide, these results suggest that Western psychologization may be more culturally specific than is Chinese somatization.     

元语言意识和快速命名对小学生汉字听写的影响

汉字听写是小学生读写能力的重要组成部分,受多种认知技能影响。以858名小学一至六年级学生为对象,考察了元语言意识（语音意识、语素意识、正字法意识）和快速命名对汉字听写的影响,在控制了智力和口语词汇的影响后,结果发现：（1）语音意识和正字法意识在低年级儿童的汉字听写中起着重要作用,对中、高年级没有显著影响;（2）快速命名在中、高年级儿童的汉字听写中起着独特作用,而对低年级没有显著影响;（3）语素意识对整个小学阶段的汉字听写都起着重要作用。研究结果表明,各认知技能在儿童不同的发展阶段对汉字听写的作用有所不同。     

当代北京大学生工作价值观结构研究

本研究旨在考察当代北京大学生的工作价值观。研究使用作者自编的调查问卷调查了北京4所大学的350名学生。调查结果揭示,当代大学生看重的工作价值观呈现4因子的结构模型,分别是:经济报酬与工作环境,个人成长与发展,组织文化与管理方式,社会地位与企业发展。与10年前的大学生需要结构相比,当代北京大学生已经从绝对个体观念转为集体中的个体观念,能够更加全方位地考虑个人的工作价值观。     

3、4岁儿童数数的规则及其策略运用的研究

数数能力是儿童用于建构其数学知识系统的重要工具,是儿童早期获得的最基本的数认知能力之一。本研究以234名3、4岁儿童为被试,采用个别测查法对儿童数数的规则及其策略运用进行了考察。研究发现：(1)随着数列数目的增大,3、4岁儿童数数精确性呈下降趋势,但4岁儿童在各项任务上的数数精确性显着高于3岁儿童;(2)3、4岁儿童在数7、10、15、30任务上的错误表现有显着差别;(3）3、4岁儿童数数策略运用存在显着差别．协方差分析显示。策略使用在数7和数10任务上具有显着效应。     

不同程度尿蛋白患者血清甲状腺激素水平变化及其临床意义

探讨不同程度蛋白尿患者血清甲状腺激素水平的变化及其临床意义。66例不同程度蛋白尿患者,肾病综合征组28例,非肾病综合征组38例,健康对照组60例。发现蛋白尿水平与甲状腺激素水平尤其是FT3水平关系密切。在肾病综合征患者,主要表现为FT3显著降低,提示肾病综合征是正常甲状腺病态综合征的一种。     

Characteristics of 12th-grade students seriously deficient in spatial ability

When spatial ability was regressed on a measure of general intelligence in a large national sample of 12th-graders, there was a distinct downturn in the regression line at about -2 SD units. A bimodal distribution of spatial ability was found among these low scoring students, suggesting 2 qualitatively different types of individuals. Relative to students of expected spatial ability, those below expected in spatial ability were high on verbal skills and low on performance skills. Students unexpectedly low in spatial ability performed relatively well on cognitive tests that required answering unambiguous questions by retrieving information directly from long term memory, whereas they performed relatively poorly on tests requiring inference and perception of relations among novel stimuli. Students unexpectedly low in spatial ability performed especially poorly at tests involving visual-spatial perception skills. Results were similar for both sexes. The relatively poor performance of those unexpectedly low in spatial ability does not appear to be related to health problems, personality, interest differences, or biographical data. An organic impairment possibly related to lateralization represents a reasonable causal hypothesis for these data.     

Counting knowledge and skill in cognitive addition: a comparison of normal and mathematically disabled children.

The relationship between counting knowledge and computational skills (i.e., skill at counting to solve addition problems) was assessed for groups of first-grade normal and mathematically disabled (MD) children. Twenty-four normal and 13 MD children were administered a series of counting tasks and solved 40 computer-administered addition problems. For the addition task, problem-solving strategies were recorded on a trial-by-trial basis. Performance on the counting tasks suggested that the MD children were developmentally delayed in the understanding of essential and unessential features of counting and were relatively unskilled in the detection of certain forms of counting error. On the addition task, the MD children committed many more computational errors and tended to use developmentally immature counting procedures. The immature counting knowledge of the MD children, combined with their relatively poor skills at detecting counting errors, appeared to underlie their poor computational skills on the addition task. Suggestions for future research are presented.
