再认条件下元监测判断的影响因素

探讨了再认条件下元监测判断的影响因素。以中文双字词对作为实验材料 ,安排在不同预先呈现时间、有无进行有意识记 ,以及不同识记遍数等条件下进行元监测判断。用计算机随机呈现项目 ,再认之前先让被试做元监测判断 ,判断是否是记过的项目的把握程度 ,再对有意识记过的项目做迫选再认 ,作为标准测验 ,以验证元监测判断的准确性。结果是预先呈现时间长、有意识记过的和识记遍数多的项目 ,对其再认的反应时较短 ,相应的元监测判断等级也较高 ;对只看而未有意记过的项目的判断是呈现时间长的判断等级反而低于呈现时间短的。此结果表明 ,再认条件下 ,元监测判断的等级的高低与识记项目的激活程度有关     

Ⅱ型糖尿病人认知功能特点

综述了近10国内外关于Ⅱ型糖尿病人认知功能特点的研究。结果表明：（1）流行病学筛查因天花板效应难以发现认知损伤。（2）采用对年老化较敏感的行为学指标证实,60~70岁的糖尿病人认知能力显著低于对照组;但60岁以下或70以上病人则少有类似表现。认知阈限理论可解释这一年龄相关现象。（3）Ⅱ型糖尿病人认知功能损伤主要表现为语词记忆损伤、学习能力下降、脑电（P300）潜伏期延长等。（4）认知损伤程度与血糖和胰岛素水平相关,也受高血压等共病因素的影响。控制糖代谢可改善认知功能。糖尿病人的认知损伤与年龄相关,但其机制不同于正常年老化过程中的认知衰退     

阅读不同颜色中、英文时的眼动特征

采用眼动实验方法,对20名大学生阅读不同颜色中、英文材料时的眼动特征进行考察。结果发现：（1）颜色对中、英文阅读成绩影响趋势一致,红色成绩最好,黄色最差;（2）颜色对被试阅读眼动指标影响差异显著：注视次数上,红色和黑色最多;注视时间上,红色最短;眼跳距离上,黄色最长;注视频率上,黄色最低。     

M(u)ler-Lyer错觉作用机制的眼动研究

使用美国应用科学实验室生产的504型眼动仪,以错觉量和眼动特征为指标,考察了Muller-Lyer(ML)错觉的产生及其作用过程.结果表明:(1)在ML错觉中,较长箭杆促进长度的准确判断,较长箭翼干扰长度的准确判断.减弱ML图形的总长度线索有助于降低错觉量;(3)箭杆与箭翼的交互作用对注视时间产生显著影响;(3)被试通过整合两条矛盾的线索进行长度判断,实验结果支持矛盾线索理论.     

基诺族左右利手分布的再调查

1981年,全国利手研究协作组对基诺族的左右利手分布作了首次调查。这次调查的结果是,基诺族全部是强右利手。这是一个非常特殊的结论。为此,一九八九年我们对基诺族的左右利手分布又作了一次调查。调查发现,基诺族并不都是强右利手,他们当中既有一般的右利手,也有混合利手,还有左利手,甚至有1.79％的强左利手。基诺族的左利率高于汉族,但与其他少数民族接近。基诺族的左利率偏高占其传统文化有关。全国利手研究协作组的调查结果应该修正。     

Sense of Control Among Hospital Employees: An Assessment of Choice Process,Empowerment, and Buffering Hypotheses1

This study examines 3 theoretical arguments explaining employees' sense of control: (a) The choice process hypothesis stipulates that employees' sense of control is a consequence of their choice processes and perceived choice size; (b) the empowerment hypothesis proposes that sense of control results from the empowerment role of social and organizational support which endorse and authorize employees' job activities; and (c) the buffering hypothesis indicates that a successful management of job-related stressors is the key to greater sense of control, and that social support plays a role in buffering the potential negative influences of job-related stressors. An assessment of the hypotheses over a sample of 1,585 hospital employees in Korea provided overall support for the choice process hypothesis and partial support for both the empowerment and the buffering hypotheses. We discuss some practical and cross-cultural research implications of the findings.     

中小学生考试成败归因的研究

从小三、初二、高二随机选择有效被试４１０名,探讨了中小学生对考试结果的归因、期望和情感反应的特点。结果发现：（１）中小学生对考试成败原因有不同的认知,年级差异显著,性别差异不显著。（２）失败后的期望显著地高于成功情境,且极显著地认为失败的结果能改变。（３）成功后学生主要产生了感激、自豪与欣慰,失败后主要产生了内疚;成功后的情感反应更强烈。     

Psychometric characteristics of the MMPI-2 Cook-Medley Hostility scale

The Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) Cook-Medley Hostility scale (Ho) has been studied a great deal because of its relation to coronary disease and mortality. However, little research has been conducted with the Ho scale on the revised MMPI (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). This study examined the psychometric characteristics of the MMPI-2 Ho scale. Only nine of the original 50 Ho items were slightly changed in the revision. Ho scores were highly correlated with MMPI-2 scales CYN, K, TPA, and ASP, supporting the interpretation of Ho as a measure of cynicism. High correlations with other MMPI-2 scales also suggested that Ho is related to general psychopathology and negative affectivity. Male Ho scorers were rated by their spouses as hotheaded, bossy, demanding, and argumentative. For women, Ho scale scores were less strongly associated with ratings of overt hostility. Principal components analysis of Ho revealed four underlying dimensions: Cynicism, Hypersensitivity, Aggressive Responding, and Social Avoidance.     

再认的两种机制及其与启动效应的关系

通过两个实验对两种再认所涉及的心理机制及其与启动效应的关系进行探讨。实验一用高频字和低频字作实验材料,分别测量集中注意和分散注意条件下,两种再认的成绩。结果表明：学习阶段的注意分散使以提取为基础的再认成绩下降,对以熟悉性为基础的再认成绩没有影响。低频字以熟悉性为基础的再认优于高频字,但字频对以提取为基础的再认没有影响。实验二分别测量两种再认项目的补笔正确率。结果表明：以熟悉性为基础的再认的补笔正确率显著高于以提取为基础的再认的补笔正确率。据此可以推论：两种再认可能有不同的心理机制。以提取为基础的再认属于有意识记忆的范畴,以熟悉性为基础的再认属于无意识记忆的范畴。后者和启动效应的心理基础可能是共同的。
