任务转换中的反应-反应相容性效应

采用任务转换范式,分别以阿拉伯数字奇偶判断和组成汉字词的汉字结构一致性判断为任务,通过两个实验探查了不同类型材料在任务转换中的反应—反应相容性效应。结果发现:(1)材料类型对反应—反应相容性效应有影响,任务转换前阿拉伯数字材料存在反应—反应相容性效应,汉字词材料不存在反应—反应相容性效应;(2)任务转换时段对阿拉伯数字奇偶判断任务的反应—反应相容性效应没有影响,转换前后阿拉伯数字奇偶判断任务都存在反应—反应相容性效应;(3)任务转换时段对汉字词任务的反应—反应相容性有影响。转换前没有反应—反应相容性效应,转换后存在反应—反应相容性效应。     

不同学业成绩类型学生的抑制控制研究

根据全市三次统考平均成绩及科任教师对学生学习能力的综合评定,选择小学三年级、五年级、初中二年级、高中二年级学生为被试（各80人）,共320人。每个年级的80人中,又分别包括四种类型（每种类型20人）,进行抑制控制测量。结果发现：抑制控制力与学业成绩有高度的相关,即（1）双优生两种抑制控制测试成绩最好;相反双差生的两种抑制控制测试成绩最差,二者差异非常显著。（2）两种偏科的学生的两种抑制控制测试成绩处于中等,二者有些项目差异显著,有些项目差异不显著。（3）双优生与两种偏科生相比,除个别项目之外,差异也十分显著,而两种偏科生与双差生相比有差异,但表现在两种抑制控制测试中各个项目的程度不一样。

赢分与输分运动员面孔表情和身体姿势情绪的加工机制*

本研究采用中国运动员赢分和输分后的表情, 通过行为学和脑电技术比较面孔表情和身体姿势的加工机制。实验1探讨了赢分与输分面孔和身体的效价和强度, 实验2考察了图片的情绪类型(中性、快乐、悲伤、愤怒、恐惧、厌恶), 实验3采用脑电技术比较了赢分和输分情绪的神经机制。3个实验的行为结果表明, 相比面孔, 身体信息更能区分赢分和输分的效价, 而且身体姿势传递的情绪内容相对单一, 面孔表情传递的情绪内容相对复杂和多样化。脑电实验的结果表明, 身体的情绪信息能更早地被大脑识别, 表现在N170成分上, 面孔表情的情绪效应, 反映在EPN成分上。在加工的晚期, 面孔和身体条件下, 均观测到胜利比失败表情诱发了更大的LPP成分。结果表明, 大脑在多个阶段对身体姿势进行情绪评估与分类, 为行为上身体对效价的高区分性提供了证据。

小学优生与差生完成系列回忆任务错误类型发展的实验研究

主要探讨了小学优生与差生在完成系列回忆记忆任务时出现错误的发展情况。实验以小学一、三、五年级的学生作为被试,每年级优生与差生各10名。以普通(不形似,不近音)、形似和近音三种类型汉字为实验材料,要求被试按材料呈现的顺序进行回忆。结果发现：在完成系列回忆任务时,小学生表现出四种错误类型,错误率从高到低依次是：移动错误、遗漏错误、侵入错误、重复错误。每一类型的错误率都是优生显著少于差生。研究还发现四种错误受材料特点的影响,即各年级小学生错误率从高到低近音字、形似字、普通字。     

Self-evaluation as a moderating factor of strategy change in directed forgetting benefits

In list method directed forgetting, instructing people to forget a studied word list usually results in better recall for a newly studied list. Sahakyan and Delaney (2003) have suggested that these benefits are due to a change in encoding strategy that occurs between the study of the first list and the study of the second list. To investigate what might mediate such strategy change decisions, in two experiments we induced bothforget and remember participants to evaluate their memory performance on the two lists. In Experiment 1, they were asked to explicitly recall the items from the first list before studying the second list. In Experiment 2, after the study of the first list, the participants provided a rapid aggregate judgment of learning. Evaluation eliminated the differences between the forget and remember groups for the second list in both experiments, because the remember group achieved recall levels comparable to those for the forget group. The role of performance evaluation in mediating directed forgetting benefits is discussed.     

Haptic pictures: fit judgments predict identification,recognition memory,and confidence

DAngiulli et al (1998 Scandinavian Journal of Psychology 39 187-190) found blind and sighted (blindfolded) children identified common objects in raised-outline drawings explored haptically, and corrected themselves without feedback. The self-correction suggests that participants can assess the extent to which the referents they suggest as possible identifications fit the haptic pictures. Indeed, when we asked subjects to identify haptic pictures, and to judge how well the referents they mentioned fitted the pictures, their fit judgments predicted the accuracy of their suggestions. Also, when one group of subjects offered the suggestions and another group assessed the fit of the suggestions to the pictures, the fit judgments predicted the accuracy of the suggestions. Further, good fit predicted successful recognition memory. In addition, both high and low fit judgments were made confidently, so the range of confidence judgments was smaller than the range of fit judgments. Finally, visual judgments of fit by one group predicted the level of success of the suggestions from another (haptic) group. In sum, subjects assess their suggested identifications appropriately, most likely on the basis of object shape criteria, outlined surface edges, and use of a vantage point.     

Perception of men's personal qualities and prospect of employment as a function of facial hair

The present study investigated the contribution of men's facial hair to impression formation. Participants evaluated photographs of one of four versions of a man--clean shaven, mustached, goateed, or bearded--on a 7-point scale. In Study 1, participants were 106 Brazilian undergraduates (68 men and 38 women). Beardedness was associated with older age, greater responsibility, and leftist political ideas. In Study 2, respondents were 50 Brazilian personnel managers (28 men and 22 women) who made hiring decisions at different companies in the city of Sa? Paulo. Personnel managers clearly preferred clean shaven over bearded, mustached, or goateed men as prospective employees. In a hiring situation for a conservative occupation, a man who signals disposition to conform to rules may be preferred by personnel managers over another who signals nonconformity.
