A Meta-Analysis of Working Memory Impairments in Autism Spectrum Disorders

Autism spectrum disorders (ASD) are characterized by executive dysfunction, and working memory (WM) comprises one core component of executive function. Many studies have investigated WM impairments in individuals with ASD, however, a conclusive agreement has not been reached. The present study provided a meta-analytic review of WM impairments in individuals with ASD and evaluated potential moderating variables of this problem. Twenty-eight studies were included in this study, and the participants comprised 819 individuals with ASD and 875 healthy controls. A significant WM impairment (Cohen’s d?=??0.61) was identified in the individuals with ASD, however, this impairment was not associated with age. Results of moderation analyses showed that (a) spatial WM was more severely impaired than verbal WM and (b) the component of cognitive processing (maintenance vs. maintenance plus manipulation) did not affect the severity of WM impairments. These findings suggest that WM is impaired in individuals with ASD and may have implications for interventions related to WM impairments in these individuals.     

Social contexts modulate neural responses in the processing of others’ pain: An event-related potential study

Two hypotheses have been proposed regarding the response that is triggered by observing others’ pain: the “empathizing hypothesis” and the “threat value of pain hypothesis.” The former suggests that observing others’ pain triggers an empathic response. The latter suggests that it activates the threat-detection system. In the present study, participants were instructed to observe pictures that showed an anonymous hand or foot in a painful or non-painful situation in a threatening or friendly social context. Event-related potentials were recorded when the participants passively observed these pictures in different contexts. We observed an interaction between context and picture in the early automatic N1 component, in which the painful pictures elicited a larger amplitude than the non-painful pictures only in the threatening context and not in the friendly context. We also observed an interaction between context and picture in the late P3 component, in which the painful pictures elicited a larger amplitude than the non-painful pictures only in the friendly context and not in the threatening context. These results indicate that specific social contexts can modulate the neural responses to observing others’ pain. The “empathic hypothesis” and “threat value of pain hypothesis” are not mutually exclusive and do not contradict each other but rather work in different temporal stages.     

母亲社会情绪行为的相关因素研究

本研究考察了婴儿情绪特征、母亲受教育程度和母亲社会情绪行为的关系。结果表明：（1）情绪特征不同婴儿的在积极社会情绪行为上无显著差异,而在消极情绪行为上,负性情绪组婴儿的显著地少于负性情绪组婴儿的母亲;（2）受教育程度不同的在积极情绪行为上无显著差异,而在消极情绪行为上,受教育程度高的母亲显著地少于受教育程度低的母亲;（3）综合考察婴儿情绪特征和母亲受教育程度两方面因素,受教育程度在大专以下、负性情绪较多婴儿的母亲在积极情绪行为上与其他组的母亲无任何差异,而其消极情绪行为显著地多于其他组的母亲。     

后现代自由主义:罗蒂政治哲学批判

Richard Rorty’s philosophy has two basic commitments: one to postmodernism and the other to liberalism. However, these commitments generate tension. As a postmodernist, he sharply criticizes the Enlightenment; as a liberal, he forcefully defends it. His postmodernist liberalism actually explains liberalism using irrationalism.

LAW培养模式在医学教育中的建立

LAW模式的建立是要改变被动的、填鸭式学习方式为积极、主动及高效的学习,培养有能力、高素质、有知识的人才。LAW模式给出学习的目标、学习方式及自我检查的标准,基本特点:多层次、多角度学习潜力的调动;启发式、以问题为导向、以学生为中心的互动学习方法;逻辑性、批判性及创造性思维的培养与应用;重点与相关学科内容的整合方式;观察、思考、信息与实践的有机结合。     

用验证性因素分析法对控制源量表的分析研究

验证性因素分析方法克服了传统的探索性因素分析的不足,为心理学发展和研究的精细化、数学化提供了更可行的途径。本研究运用验证性因素分析方法对心理控制源量表进行了分析研究,研究发现L1SREL软件对SPSS不能分析出来的因素可以进一步地给予精确数据。     

应用题结构分析训练对提高小学生解题能力的实验研究

实验以小学四年级学生为被试,采用完全随机化等组设计。实验组采用应用题结构分析训练教学模式,控制组在同等时间内,采用常规教学模式作相同的习题练习。实验结果表明：（１）应用题结构分析训练可显著提高小学生解应用题的能力,中等生受益最大;（２）该模式训练效果与学生的智力水平呈中等程度正相关;（３）学生对该训练模式持肯定态度,反应积极。     

汉词和图画再认的ERP效应及脑机制

目的：比较汉词与图画材料再认过程中的事件相关电位（ERP）表现并探讨其脑机制。方法：使用经典“学习一再认”实验模式对21名大学生进行测验,同时记录EEG,离线处理后对汉词及图画再认诱发的ERP波形主要成分及新旧效应进行比较。结果：两种材料的再认均诱发出了明显的新旧效应。顶区新旧效应头皮分布基本一致,但图画再认该效应波幅大于汉词再认;两种材料诱发的额区新旧效应有所不同,图画再认该效应为正走向,而汉词再认此效应表现为负走向趋势。结论：汉词与图画再认既存在某种共同的神经加工机制,叉分别涉及一些特异性的神经活动模式。
