成年人日常生活记忆的研究

采用三项记忆作业,对１２０例２０—８５岁的被试进行日常记忆和实验室记忆的比较研究,目的为探讨日常记忆的年龄差异及其年老化特点。结果表明：（１）三项记忆成绩均随增龄而减退,其中年老老年组减退明显;（２）作业难度比较：经方差分析结果表明,它对记忆成绩有显著作用,作业难度自评与方差分析相符,“地名”最易,“人姓”居中,“无意义图形再认”最难,因为“地名”为日常生活记忆,难度小于后者（为实验室记忆）。老年人日常生活记忆减退缓慢,他们可利用知识经验补偿记忆减退,使之保持较好。     

人际作用过程与团体工作效率的关系

本研究以中师生为样本,检验了合作行为与冲突处理的关系;冲突处理方式、对处理人际差异的积极预期与团体工作效率的关系;领导风格与团体工作效率的关系。本研究比照西方研究、结合中国文化,对回避冲突的作用作了分析。     

Leadership emergence in task groups with egalitarian gender-role expectations

Although they differ in their explanations of the antecedents of gender-role expectations, gender role and expectation states theories agree that mixed-sex and initially leaderless task groups will confirm these expectations by selectively reinforcing male task participation and leadership emergence. Based upon this assumption held in common by the two theories, we hypothesized that groups whose members expressed significantly egalitarian gender-role expectations would reinforce male and female task participation and leadership emergence impartially. Analysis of data from 31 mixed-sex groups whose members expressed significantly egalitarian gender-role expectations, and who were racially and ethnically homogeneous, found that males participated more in group discussions and were more likely to be selected as task leaders. Male advantages were explained only partly by token effects and their advantages in task resources. Implications are suggested for theories of male and female role performance in initially leaderless groups.     

50—90岁成人的短时记忆研究

本工作研究了102例50—90岁成人的短时记忆,其中85例进行了较详细的体格检查。以22例20—25岁青年的记忆检查作为对照,结果看到: 1.在图片自由回忆、逻辑故事识记、数字广度识记三个项目上,记忆都有随年龄增长而逐步减退的明显趋势; 2.识记逻辑故事时,对中心意义的记忆减退较分节记忆减退缓慢,顺背数字的记忆广度随年龄增长而减小较其他项目都要缓慢,表明老年记忆减退有其特点; 3.神经系统和心血管系统的病理性或老年性变化与记忆减退有关。     

记忆与学习的脑化学研究 Ⅱ.海马内注射胰蛋白酶与胰凝乳蛋白酶对大白鼠暗箱迴避模式记忆的影响

本实验选择了胰凝乳蛋白酶与胰蛋白酶,它们同属水解酶,能够内切蛋白质与肽类底物的某些键位。26只刚成年的雄性大鼠分作三组:生理盐水/不巩固组(NS/NC)、胰蛋白酶/不巩固组(T/NC)与胰凝乳蛋白酶/不巩固组(CT/NC)。 实验结果表明,双侧海马内注射(AP_2L_2H_4与AP_4L_3H_5)胰凝乳蛋白酶与胰蛋白酶后,对暗箱廻避(DBA)模式记忆有不同的影响。胰蛋白酶注射后,该记忆保持明显降低,而胰凝乳蛋白酶注射后仍可巩固。所用的实验剂量大致为半致死剂量的三分之一。     

论孔子思想的实践指归

关于孔子思想的实质与核心问题 ,学界曾进行过多次争论 ,但迄今为止并未形成统一的认识和观点。蔡尚思先生在 6 0年代曾撰文认为 ,“孔学主要是礼学”,80年代初在他的《孔子思想体系》中又明确提出“孔子思想体系的中心是礼”。匡亚明先生则认为 ,“仁”是孔子的哲学 ,也是他的伦理道德学说、政治学说、教育学说 ,一句话 ,是他的全部博大庞杂的思想体系的“一以贯之”的总纲。 (见匡亚明著《孔子评传》,第 1 92页 ,齐鲁书社 1 985年版 )也有人提出 ,中庸是孔子思想的实质和核心 (见郭碧波《孔子思想核心再认识》,载《哲学研究》 1 985年第 9…     

上下文熟悉效应对元记忆监测和记忆的影响

在认知任务中,伴随编码和检索的外围信息被称为上下文,其本身并不是编码或检索的目标。如果学习时的上下文在其后进行提取时重复出现,不管是否对应之前的学习项目,都会增加个体再认正确的概率。这种由于上下文增强项目熟悉感而促进记忆效果的现象就称为上下文熟悉效应。本研究通过两个实验探究上下文熟悉效应对元记忆监测及记忆的影响机制。其中,元记忆监测是以学习判断和信心判断为指标。记忆成绩则是以再认正确率为指标。研究结果显示:第一,上下文熟悉效应影响元记忆监测:学习判断等级上,恢复条件显著高于新条件,且不受任务难度影响; 信心判断等级上,简单任务时恢复条件与新条件无显著差异,困难任务时恢复条件显著高于新条件。第二,上下文熟悉效应影响记忆成绩:再认成绩上,简单任务时新条件显著高于恢复条件; 困难任务时恢复条件显著高于新条件。研究得出结论:上下文熟悉效应对元记忆监测和记忆都有显著影响,任务难度起调节作用。

From teachers’ implicit theories of intelligence to job stress: The mediating role of teachers’ causal attribution of students’ academic achievement

To better understand the cognitive antecedents of teachers’ stress in the school setting, the effects of teachers’ beliefs regarding intelligence and their causal attributions of students’ academic performance on teachers’ job stress were examined in the current study. We recruited 271 teachers who voluntarily filled out an anonymous questionnaire. Findings demonstrated that teachers who endorsed the entity theory of intelligence tended to attribute students’ poor performance to students’ inability but not lack of effort. Results showed a positive relationship between teachers’ fixed view of intelligence and job stress, and this relationship was mediated by teachers’ attributing students’ poor performance to students’ lack of ability, even after controlling for teacher efficacy. We suggest to promote the psychological health of teachers by incorporating intelligence mindset and attribution training programs in preservice teacher education, professional development, and cognitive behavioral stress intervention for in-service teachers.
