7～9岁儿童失言理解与执行功能的关系

为了说明学龄儿童心理理论与执行功能的关系,研究采用失言理解、威斯康星卡片分类和汉诺塔任务分别考察了90名7—9岁儿童的心理理论和执行功能。结果表明,失言理解与抑制-转换能力相关显著（r=0．34,P〈0．01）,但是与计划能力相关不显著（r=0．06,P〉0．05）。在控制年龄后,失言理解与抑制-转换能力的相关仍然显著（r=0．29,P〈0．05）。研究结果说明,学龄儿童心理理论与执行功能的相关模式与学龄前儿童完全一致,提示心理理论与执行功能的相关关系从学龄前延续到了学龄阶段。     

7~9岁儿童二级错误信念和失言理解的发展

采用二级错误信念任务、失言理解任务分别考察了90名7-9岁学龄儿童心理理论的发展。结果表明,7岁组儿童在二级错误信念和失言理解任务上的成绩与8岁组、9岁组存在显著差异,但8岁组和9岁组儿童之间没有显著差异,提示8岁可能是个体心理理论发展的又一个转折点。三组被试在二级错误信念理解上的成绩显著高于失言理解任务上的成绩,在控制年龄后,他们在两种心理理论任务上的成绩显著相关。另外,失言任务中三种心理状态理解的得分两两相关。综合以上结果,在学龄期,心理理论仍有质的发展,且心理理论的信念、情绪和意图等核心概念仍然相互关联。     

5～8岁儿童失言探测与理解的发展特点

失言探测与理解是一种融入了人际互动,需要个体体会交往双方心理感受的高级心理理论任务.本研究采用图片-故事法探讨失言情境(他人对自我、自我对他人和他人对他人 )对5～8岁儿童失言探测与理解的影响.结果发现,7～8岁儿童基本拥有了失言探测与理解能力,6、7、8岁儿童在所有情境下失言探测和理解能力同步发展,而5岁儿童在他人对自我情境下失言探测与理解的成绩显著好于自我对他人情境下的成绩,提示失言探测与理解能力在不同阶段会表现出不同的发展特点.     

基于易感人格的药物成瘾者工作记忆对执行控制功能的调节作用

为了解工作记忆在易感性人格对药物成瘾者执行控制功能和抑制性影响过程中的调节作用,采用BIS和SSS量袁以及连续操作测验（CPT）、2-back任务、威斯康星卡片分类任务（WCST）对150名药物成瘾者和100名年龄、性别及智商相匹配的非药物成瘾者实施冲动性人格、认知控制功能测试。结果发现在2-back任务正确率（工作记忆）高低不同的情况下,注意冲动性人格特质得分对执行控制功能会产生不同的影响。这说明工作记忆在冲动性人格对抑制性的影响中具有调节作用。     

7-11岁儿童心理状态信息理解与使用的发展特点及关系

采用失言任务和改进的说服任务考察了153名7-11岁儿童的心理理论理解和使用能力的发展状况。结果发现：儿童的失言理解能力和心理状态信息使用能力7-9岁时发展迅速,9岁后趋于稳定;两种能力的发展趋势基本一致,两者呈现中度相关;8-9岁是儿童失言理解和心理状态信息使用发展的转折点。结果表明：心理状态理解和使用的能力是儿童心理理论发展的重要组成部分,两者的发展基本同步。     

学龄前儿童社会善念理解的发展与心理理论的关系

本文探究了4~6岁儿童社会善念理解的发展及其与心理理论的关系。研究测量了100名4~6岁儿童的社会善念理解、心理理论、亲社会性和执行功能。结果发现, 随着年龄增长, 儿童愈加在社会评价和朋友偏好上倾向于社会善念人物, 并且此社会善念理解能力与心理理论的发展呈显著正相关, 且此相关在控制了年龄、执行功能及亲社会性后依然稳定存在, 但社会善念理解与亲社会性并不相关。此结果表明, 心理理论可能对社会善念理解的发展有重要作用。     

研究心理理论的新方法——失言识别任务

心理理论是对他人心理状态进行推论的能力。考察心理理论的经典范式是错误信念任务, 而青少年和成人在这种任务上可能出现天花板效应。为了测量青少年和成人的心理理论, Valerie E. Stone和她的合作者设计了失言识别任务。征求了Stone意见, 对失言识别任务的提出、构成、使用进行了介绍, 说明了该任务相对于经典范式的优势; 与此同时, 分析了失言识别任务范式存在的一些问题, 比如其效度指标问题, 与言语能力的分离问题, 失言识别任务与执行功能之间的分离等。未来研究可以尝试编制失言识别任务的本土化的量表, 并利用其探讨年长个体心理理论水平发展变化的规律。     

基于反馈加工的规则学习:研究儿童认知灵活性的新范式

认知灵活性作为执行功能的三个主要成分之一,对个体能力发展和环境适应起着重要作用。但以往研究多采用不同范式来考察不同年龄段儿童在一个优势规则失效后灵活转换至新规则的能力。本研究旨在威斯康星卡片分类任务(WCST)的基础上设计一种新任务范式,考察年龄范围更大的群体在规则习得过程中根据不同性质的反馈信息保持与灵活修订假设的能力。我们设计了目标选择任务(target choose task,TCT),考察181名5~11岁儿童的认知灵活性。其中24名儿童亦完成WCST。结果表明,TCT通过率界于32~65.7%;TCT高分组成绩显著高于低分组;分半信度计算结果表明奇数编号题目与偶数题目得分正相关;TCT分数与WCST完成分类数和概念化水平数分别呈正相关。这些结果表明TCT难度适中,具有区分度,内部一致性高,效度良好,可以在更大的年龄跨度上研究儿童在规则习得过程中的认知灵活性。     

不同维度的执行功能与早期心理理论的关系

采用意外地点任务、意外内容任务和三种不同类型的执行功能任务来探究执行功能与心理理论之间的关系。共60名被试,3岁和4岁被试各30名,男女各半。区分自己心理状态和他人心理状态能力与执行功能的关系主要体现在混合成分执行功能与这一能力的密切联系上;在错误信念发展的早期,执行功能与错误信念理解能力的关系主要集中在“混合成分的执行功能与对自己错误信念理解能力,工作记忆的执行功能与对他人错误信念理解能力”这两对联系上     

7～11岁儿童失言理解及与母亲教养方式的关系

采用失言任务和改编后的教养方式问卷探讨7~11岁儿童心理理论的发展及其与母亲教养方式的相关。结果表明,在学龄期,儿童在不同层面上对失言的理解能力仍在提高,高年级时已超出单一维度。7岁儿童对包含意图的信念理解与母亲的"过度偏爱"显著负相关;8岁儿童对包含意图的信念理解与母亲的"惩罚和严厉"显著负相关。结果提示在某些年龄阶段,儿童心理理论的发展可能与母亲特定的教养方式有关。     

Aging of theory of mind: The influence of educational level and cognitive processing

Previous studies of theory of mind (ToM) in old age have provided mixed results. We predicted that educational level and cognitive processing are two factors influencing the pattern of the aging of ToM. To test this hypothesis, a younger group who received higher education (mean age 20.46 years), an older group with an education level equal to that of the young group (mean age 76.29 years), and an older group with less education (mean age 73.52 years) were recruited. ToM tasks included the following tests: the second‐order false‐belief task, the faux‐pas task, the eyes test, and tests of fundamental aspects of cognitive function that included two background tests (memory span and processing speed) and three subcomponents of executive function (inhibition, updating, and shifting). We found that the younger group and the older group with equally high education outperformed the older group with less education in false‐belief and faux‐pas tasks. However, there was no significant difference between the two former groups. The three groups of participants performed equivalently in the eyes test as well as in control tasks (false‐belief control question, faux‐pas control question, faux‐pas control story, and Eyes Test control task). The younger group outperformed the other two groups in the cognitive processing tasks. Mediation analyses showed that difficulties in inhibition, memory span, and processing speed mediated the age differences in false‐belief reasoning. Also, the variables of inhibition, updating, memory span, and processing speed mediated age‐related variance in faux‐pas. Discussion focused on the links between ToM aging, educational level, and cognitive processing.     

Elevated emotional reactivity in affective but not cognitive components of theory of mind: A psychophysiological study

Recent research proposes that theory of mind (ToM), that is the ability to infer other people's mental state, is a multidimensional construct and that a distinction may be made between affective and cognitive ToM. We examined whether these two subcomponents of ToM correspond to different levels in skin conductance responses (SCRs). Seventeen healthy adults listened to ten affective (faux pas) ToM stories, ten cognitive ToM stories and ten non‐ToM stories. Results demonstrated significantly elevated SCR for affective ToM as compared with cognitive ToM and control stories, with no differences in SCR levels in the latter two story types. We discuss the possible underlying mechanisms for these differential psychophysiological correlates of affective and cognitive ToM processing, and suggest further investigations especially in clinical populations.     

聋童执行功能发展：聋童与正常儿童的比较

利用标准Dimensional Change Card Sort任务(DCCS),对76名智力正常的3~8岁聋童和78名3~5.5岁的正常儿童进行了对比测试,旨在考察聋童执行功能发展的年龄特征与发展水平。结果发现,3岁组的聋童和正常儿童在DCCS任务上的表现没有显著性差异,但正常儿童在4~4.5岁时进入一个迅速发展期,而聋童要在6岁时才有快速的发展,到7岁后才相当于正常儿童5岁的发展水平,大约滞后2年。研究认为,造成聋童执行功能发展滞后的原因主要有：（1）语言符号系统和聋童特有的符号系统之间可能存在的差异;（2）聋童可能存在计划和灵活性的缺陷;（3）聋童可能存在命名和标识策略上的困难和注意机制的缺陷。结合关于聋童心理理论发展滞后于正常儿童7年以上的报道,心理理论发展和执行功能发展在聋童身上表现出较大的不一致性。     

Childhood abuse and neglect and cognitive flexibility in adolescents

Childhood maltreatment (CM) has been associated with diminished executive functioning in children and adults; however, there is a relative paucity of study of executive function in adolescents exposed to CM. Yet, executive dysfunction in adolescence may have important adverse consequences including increased vulnerability to risky behaviors and impaired school functioning. This study investigates the relationship between self-reported CM and an executive function, cognitive flexibility, in adolescents without identified psychiatric disorders. Effects of physical and emotional, abuse and neglect, maltreatment subtypes were explored. Thirty adolescents ages 12-17 years, 50% females, completed the retrospective self-report Childhood Trauma Questionnaire (CTQ) and were administered the Wisconsin Card Sorting Test (WCST). Correlational analyses assessed the relationship between WCST perseverative error scores norm-referenced for age and education with CTQ total scores. The relationship with nonperseverative errors, as well as with physical and emotional abuse and neglect CM subscores, were explored. Total CTQ scores showed significant associations with perseverative errors on the WCST, but not with nonperseverative errors. Significant associations with perseverative errors were seen for physical abuse and physical neglect among the CTQ subscales. The results suggest both physical abuse and physical neglect are associated with diminished cognitive flexibility in adolescents. These effects were detected in adolescents without identified psychiatric diagnoses suggesting the importance of considering executive dysfunction in adolescents exposed to CM who may not meet diagnostic criteria for an Axis I disorder and that tests of perseverative errors, such as those of the WCST, may be sensitive indicators of this dysfunction.     

The influence of functional social support on executive functioning in middle-aged African Americans

ABSTRACT

Social support has a positive influence on cognitive functioning and buffers cognitive decline in older adults. This study examined the relations between social support and executive functioning in middle-aged adults. A community-based sample of African Americans completed the Interpersonal Support Evaluation List, a measure of functions of social support, and two measures of executive functioning, the Stroop Color and Word Test and the Wisconsin Card Sorting Test (WCST). Hierarchical regression analyses were used to explore the hypothesis that different facets of perceived social support influence performance on measures of executive functioning. After controlling for age, gender, and education, social support facets including belonging support, selfesteem support, appraisal support, and tangible support were significant predictors of Stroop performance. In addition, tangible support significantly predicted WCST performance. These findings add to previous literature on social support and cognition; however, findings for middle-aged adults are unique and suggest that social support has a positive influence on some executive functions in African Americans prior to old age.
