情绪性工作记忆对选择性注意的影响

选取大学本科生33名,采用情绪启动范式与再认范式相结合,要求被试依次完成情绪词识记、目标面孔性别判断及情绪词再认任务,探讨保存于工作记忆中的情绪性刺激对面孔性别判断任务的影响。结果显示:(1)在中性和恐惧情绪启动刺激条件下,被试对目标面孔性别判断的反应时要显著长于悲伤条件。(2)在愉悦情绪启动词条件下,线索提示有效性差异显著;在无效线索提示条件下,启动刺激的不同情绪效价差异显著。(3)对情绪面孔性别与被试性别一致性/非一致性两种条件下反应时对比发现,男、女被试在情绪面孔性别判断任务中均表现出异性相吸效应。综上所述,保存在工作记忆中情绪刺激会对面孔性别的识别产生自上而下的影响。     

生存加工的编码和提取双重优势效应:ERP证据

生存加工比控制条件有更好的记忆表现,产生稳定的记忆优势,这就是记忆生存优势.已有研究多采用行为学实验验证了此现象的存在,但没有确定该优势发生在记忆的何种阶段.本研究采用ERP技术和“间接学习-再认”实验范式,比较被试在生存情境、迁徙情境和愉悦判断中对词汇编码和提取过程的记忆加工,结果发现:在500-700ms时间段,生存情境的相继记忆效应显著大于迁徙情境和愉悦判断:在400-600ms时间段,生存情境的新旧效应显著大于迁徙情境和愉悦判断.表明生存加工具有编码和提取双重优势.     

小学生工作记忆与推理关系的实验研究

本实验以视觉同时呈现,在形近、音近、义近三种干扰下以再认方法和瑞文渐进推理测验探讨了小学生年级、性别、工作记忆与推理的关系。发现(I)小学生工作记忆与推理能力相关显著。(2)工作记忆和推理能力在小学阶段不存在性别差异。(3)年级和工作记忆是影响小学生推理能力的重要因素,但年级因素对推理能力的作用较工作记忆大。     

汉语语句重音的分类和分布

通过两个独立进行的重音标注实验对汉语语句重音的分类和分布进行了初步探讨。实验l是由60位普通被试参加的音节重音突显度的知觉实验。实验2是由本文三位作者参加的重音类别标注实验,在此实验中语句重音被划分为节奏重音和语义重音。实验2中对于语句重音的分类性标注结果得到了实验l中普通被试对音节重音突显度知觉结果的支持,这说明人们确实能够感知到两种不同类型的重音。实验结果还表明,节奏重音倾向于出现在较大韵律单元内的最末韵律词的末音节上,并且与适当的停延相伴生,语义重音的分布则与语句的韵律结构的关系不大。     

同伴团体对儿童青少年学业成就和社会功能关系的影响

运用同伴评价、教师评估和学校记录等多种渠道收集关于同伴团体、社会功能、同伴接纳以及学业成就的资料,旨在考察同伴团体与儿童青少年学业成就和社会功能的关系。研究发现：绝大多数儿童青少年都有自己的同伴团体。这些同伴团体在学业成就上有很高的同质性。学业成就与社会适应无论在团体内的个体水平还是在团体水平上都密切相关。而且,团体的学业表现是个体学业成就和社会适应间的重要调节因素,表明团体学业规范对个体水平上学业成就与社会功能的关系有增强或是减弱的作用。这项研究再一次证明同伴团体在儿童个体发展中的重要意义。     

无名相之法以名相说——论维摩诘王氏说及其眷属

本文对流传于中土的维摩诘王氏说及其眷属做了考察,认为这些说法撰造于南朝齐梁陈时代,它们的流行是佛法通俗教化的结果,与印度佛教传统中以传述圣贤事迹为主的大譬喻经或大因缘经有直接联系,标志着中土维摩诘信仰由士大夫阶层向民间普及的发展趋势。     

Stereotype activation is unintentional: Behavioural and event‐related potenials evidence

In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no‐priming) and the relationship between priming and target (consistent/inconsistent/no‐relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction time revealed that stereotype activation is, to some extent, unintentional. Furthermore, the event‐related potenial (ERP) results showed that N400 amplitude was larger for inconsistent conditions than for consistent conditions. This result supported the notion that stereotype activation is an unintentional and automatic process.     

A Brief Group Cognitive-Behavioral Program for the Prevention of Depressive Symptoms in Chinese College Students

Depression is a problem among college students in China. Yet the use of preventative group cognitive-behavioral (CB) intervention is rare. One hundred and eighty Chinese college students who were identified as being at risk for depression were randomly assigned to three groups: 1) a brief group cognitive–behavioral (CB) intervention, 2) a supportive group (SG) intervention, and 3) a wait-list control condition. The Zung Self-Rating Depression Scale (SDS), the Zung Self-Rating Anxiety Scale (SAS), and the Chinese College Student Adjustment Scale (CCSAS) were administered at pre-test, post-test, and six-month follow-up. Analysis of variance (ANOVA) conducted among the three groups revealed that the CB group demonstrated significantly less increase in measures of primary symptoms of anxiety and depression than the wait-list controls at post-test and six-month follow-up. The prevention effect of the SG group was significant only at the six-month follow-up. CB participants also showed significantly greater improvements in social adjustment than did SG participants and controls at the post-test and six-month follow-up.     

Family Environments and Children's Executive Function: The Mediating Role of Children's Affective State and Stress

There is increasing evidence that inadequate family environments (family material environment and family psychosocial environment) are not only social problems but also factors contributing to adverse neurocognitive outcomes. In the present study, the authors investigated the relationship among family environments, children's naturalistic affective state, self-reported stress, and executive functions in a sample of 157 Chinese families. These findings revealed that in inadequate family material environments, reduced children's cognitive flexibility is associated with increased naturalistic negative affectivity and self-reported stress. In addition, naturalistic negative affectivity mediated the association between family expressiveness and children's cognitive flexibility. The authors used a structural equation model to examine the mediation model hypothesis, and the results confirmed the mediating roles of naturalistic negative affectivity and self-reported stress between family environments and the cognitive flexibility of Chinese children. These findings indicate the importance of reducing stress and negative emotional state for improving cognitive functions in children of low socioeconomic status.     

The modality effect of ego depletion: Auditory task modality reduces ego depletion

An initial act of self‐control that impairs subsequent acts of self‐control is called ego depletion. The ego depletion phenomenon has been observed consistently. The modality effect refers to the effect of the presentation modality on the processing of stimuli. The modality effect was also robustly found in a large body of research. However, no study to date has examined the modality effects of ego depletion. This issue was addressed in the current study. In Experiment 1, after all participants completed a handgrip task, one group's participants completed a visual attention regulation task and the other group's participants completed an auditory attention regulation task, and then all participants again completed a handgrip task. The ego depletion phenomenon was observed in both the visual and the auditory attention regulation task. Moreover, participants who completed the visual task performed worse on the handgrip task than participants who completed the auditory task, which indicated that there was high ego depletion in the visual task condition. In Experiment 2, participants completed an initial task that either did or did not deplete self‐control resources, and then they completed a second visual or auditory attention control task. The results indicated that depleted participants performed better on the auditory attention control task than the visual attention control task. These findings suggest that altering task modality may reduce ego depletion.
