自尊与记忆偏向的关系

采用2（外显自尊：高、低）×2（内隐自尊：高、低）×2（编码深度：浅、深）×3（词汇效价：积极、中性、消极）混合设计,考察了89名不同自尊类型的大学生在不同编码深度下对不同效价形容词的再认记忆。结果发现：（1）在浅水平编码组中,低内隐自尊被试比高内隐自尊被试有更强的积极记忆偏向,而高低不同水平的外显自尊者对于词语记忆偏向没有显著差异;（2）在深程度编码组中不同自尊水平影响被试对积极词的无意识提取;（3）所有被试均有积极记忆偏向。     

Memory for emotional words: The role of semantic relatedness,encoding task and affective valence

Emotional stimuli have been repeatedly demonstrated to be better remembered than neutral ones. The aim of the present study was to test whether this advantage in memory is mainly produced by the affective content of the stimuli or it can be rather accounted for by factors such as semantic relatedness or type of encoding task. The valence of the stimuli (positive, negative and neutral words that could be either semantically related or unrelated) as well as the type of encoding task (focused on either familiarity or emotionality) was manipulated. The results revealed an advantage in memory for emotional words (either positive or negative) regardless of semantic relatedness. Importantly, this advantage was modulated by the encoding task, as it was reliable only in the task which focused on emotionality. These findings suggest that congruity with the dimension attended at encoding might contribute to the superiority in memory for emotional words, thus offering us a more complex picture of the underlying mechanisms behind the advantage for emotional information in memory.     

The phenomenology and temporal distributions of autobiographical memories elicited with emotional and neutral cue words

In this study we examined whether the temporal distribution of autobiographical memory changes when different types of cue words are used to elicit the memories, and how the type of cue word affects the phenomenal characteristics of the memories. A total of 76 participants, ranging in age from 21 to 69 years, were presented with 22 cue words (emotional, emotion-provoking, and neutral). They were asked to recall a personal event and to complete the Autobiographical Memory Questionnaire (Rubin, Schrauf, & Greenberg, 2003, 2004) for each cue word. Results showed that the phenomenological properties of autobiographical memories which were cued with emotional and emotion-provoking words were rated higher than those of memories which were cued with neutral words, and that the peak in the temporal distributions of the autobiographical memories that were cued with emotional or emotion-provoking words were located later than the peak of the distribution of the memories that were cued with neutral words.     

字词认知N170成分及其发展

字词认知早期的N170成分是第一个对语言材料敏感的成分.最近对字词认知N170成分的研究主要集中在探讨其敏感性、偏侧化以及此成分的发展变化.大量研究认为字词N170成分的敏感性与正字法加工有关,但也有一些研究认为其受语音、语义调制.对于此成分的偏侧化研究结果较一致认为是左侧化.最近的发展研究对N170成分进行探讨,取得了一些成果.在剖析现有研究基础上,本文认为应对字词认知N170成分的偏侧化、功能分离等问题进行深入研究.     

自然阅读与校对阅读的知觉广度研究

采用经典的移动窗口技术,以Eyelink2000型眼动仪为工具,探讨了自然阅读和校对阅读两种不同的任务对中文阅读知觉广度的影响,结果表明：（1）与校对阅读条件相比,自然阅读条件下的阅读速度更快、眼跳幅度更大。（2）自然阅读条件下被试的知觉广度为注视点右侧2-3个字;校对阅读条件下被试的知觉广度仅为注视点1个字的空间。结果说明,读者在校对阅读和自然阅读条件下采用了不同的阅读策略,阅读知觉广度的大小受任务要求的影响。     

尝试提取复杂信息失败的学习：吃一堑长一智？

摘 要：在学习中,提取失败能否产生对知识的有效学习是一个很有意义的研究课题。以事实和概念类知识为实验材料,三个实验采用经典范式探讨了复杂意义条件下的提取失败后的学习效果。结果显示仅在尝试提取事实类题目失败后,促进了知识的保持和迁移;在迁移成绩上延时反馈优于即时反馈的效果。表明尝试提取复杂材料的信息失败后,知识的类型和反馈的时机决定了学习效果。     

创业环境与大学生创业意向的关系:有调节的中介模型

本研究提出一个有调节的中介模型,揭示了创业环境"怎样"影响大学生创业意向及这种影响"何时"更强或更弱。采用创业环境量表、创业动机量表、创业意向量表对647名大学生进行研究。研究显示:(1)创业动机在创业环境与大学生创业意向之间起部分中介作用;(2)性别调节了创业环境通过创业动机影响大学生创业意向的中介过程的前半路径。因此,创业环境对大学生创业意向的影响是有调节的中介效应,研究结论对提高大学生的创业意向具有重要的理论与实证价值。     

阅读中词汇视觉编码年老化的原因:基于消失文本实验的证据

研究采用消失文本范式、操控双词消失的延迟时间,考察中文读者编码两个相邻词汇（词n与词n+1）视觉信息的年老化问题。结果发现,从40 ms延迟时间至160 ms延迟时间的所有消失条件均不影响青年人的句子总阅读时间,这意味着青年人能够并行、快速地同时编码词n与词n+1的视觉信息;而所有消失条件都影响老年人的句子阅读时间,40 ms延迟时间消失条件对总阅读时间的影响程度甚于其他较长延迟时间的消失文本条件,80 ms、120 ms和160 ms延迟时间消失条件对总阅读时间的影响程度完全相同。由这些结果可以确定,中文阅读中词汇视觉编码的年老化同时受视觉与认知因素衰退的影响。     

非熟练双语者言语产生中非目标语言的激活范围

采用图-图干扰范式来考察非熟练中-英双语者言语产生中非目标语言的激活范围。实验1探讨用汉语命名时,干扰图的英语名称能否得以激活。结果发现,干扰图的词汇熟悉度高时,音译词的反应时显著长于音韵无关词,而熟悉度低时,二者无显著差异,说明在一语的产生过程中只能激活二语中高熟悉的非目标词。实验2探讨用英语命名时,干扰图的汉语名称能否激活。结果发现,不论熟悉度高还是低,音译词的反应时均显著长于音韵无关词,说明在二语的产生过程中会激活一语中的非目标词。总的结果说明,非熟练中-英双语者在言语产生过程中非目标语言中的非目标词也会激活,并且激活范围既受非目标语言的熟练程度的影响,也受非目标词熟悉度的影响。     

提取-消退范式中复合刺激对恐惧消退的影响

情绪障碍治疗的关键在于消退条件性恐惧记忆,研究证明基于记忆再巩固的提取-消退范式能有效消除或改写原有的恐惧记忆。本研究将提取-消退范式应用到更复杂的恐惧记忆中,采用多感官复合刺激(声音+图片)作为条件刺激,以皮电反应作为恐惧反应指标,考察采用单个线索(声音或图片)、复合线索(声音+图片)进行提取-消退对条件性恐惧记忆的消退效果有何差异。结果表明:声音线索提取-消退组出现了自发恢复和重建效应,图片提取-消退组只出现了重建效应,复合刺激提取-消退组未出现自发恢复和重建效应。说明由复合刺激线索引发的条件性恐惧,采用复合刺激中的单个较强线索或原有完整线索进行提取-消退,对恐惧记忆的消退效果最好。
