论执行功能及其发展研究

执行功能(executive function,EF)是一个还没有明确定义的概念,但又是一个重要的概念,通常是指个体对思想和行动进行有意识控制的心理过程。目前的主要观点包括神经心理学观点、抑制控制理论、高级认知能力理论(包括工作记忆理论、抑制及工作记忆理论)和认知复杂性和控制理论。主要的研究任务类型包括卡片分类任务、延迟反应任务、基于Stroop任务的冲突反应模式任务、心理理论任务、问题解决任务、“热”执行功能任务等。未来的研究应着重弄清执行功能的本质,结合认知神经科学阐明其与脑神经结构和功能的关系,并从区分“冷”执行功能和“热”执行功能的角度,探讨以情感激活为特点的“热认知”在执行功能中的作用。     

执行功能研究方法评述

虽然对执行功能的研究长期以来都是从神经心理学角度出发的,但现在发展心理学领域中也出现了大量的研究,其研究方法也层出不穷。该文从发展心理学角度分析了研究儿童冷执行功能和热执行功能的常用方法,包括搜寻任务、规则运用任务、优势规则抑制任务、矛盾冲突任务、问题解决任务、图片工作记忆任务、心理理论任务、延迟满足任务、儿童博弈任务和反向择物。通过对这些方法的分析,作者发现,执行功能的概念已逐步扩展到包容整个认知过程,而已有的关于执行功能的观点都只强调了其中某一个或几个方面,还没有一种观点能够将上述方法所研究的执行功能概括完整。执行功能的本质还远远不能清晰地展示在我们面前。     

认知复杂性与意识水平:Zelazo理论述评

Zelazo等人提出的认知复杂性和控制理论、意识水平模型认为可在问题解决框架内理解执行功能,且执行功能的变化可根据儿童形成和使用的最大规则复杂性的变化来描述,而规则复杂性的变化可根据儿童意识水平的变化来解释。Zelazo的理论提出后受到不少研究者的关注,但也存在一些问题和不足。     

西方心理学自我同一性概念的解析

我同一性作为西方心理学中一个重要的概念,广泛地应用于发展心理学、人格心理学、社会心理学、咨询心理学、教育心理学和文化心理学。但由于自我同一性概念内涵的丰富与复杂以及研究者理论框架的不同,使自我同一性的概念缺乏明确统一的定义,从而影响了同一性概念的理论功能。本文分析了埃里克森自我同一性概念的奠基、自我同一性概念的实证研究以及自我同一性概念发展的新趋向,透视了西方心理学自我同一性概念不同层面和不同维度上的含义。最后,提出了整合自我同一性概念应关注的范畴以及自我同一性概念的理解。     

认知年老化与执行衰退假说

在认知年老化领域,执行衰退假说是近年来新兴的一种理论。执行衰退假说在理论上具有很强的吸引力,但在实证研究中却存在很多困难,如执行功能的可分离性问题,执行功能测量的信度和效度问题,以及执行功能与加工速度的关系问题。目前,该领域研究的焦点是：在行为学水平上,控制一般性因素（加工速度）后,执行功能是否仍对认知年老化起重要的中介作用;在神经水平上,执行（额叶）功能随龄的变化情况,以及在认知年老化过程中,额叶在大脑功能重组中扮演的角色。最终实现对认知年老化的理解,需要将认知功能与大脑结构联系起来;既看到广泛存在的共同的基本机制,又不能忽略不同认知结构的选择性变化。     

概念结构理论

本文不从概念的外延和内涵出发,而是将概念作为初始出发点,按照概念结构整体论的观点,在思想-概念-语言三者统一的基础上,建立概念结构的形式理论,讨论其基本性质及其意义,并在此基础上研究若干相关的问题。实际中使用的推理,比我们通常说的逻辑推理要更广泛,本文建立依赖于语言的相对于主体的推理,并根据这种相对的推理建立相对的一致性概念。通过这种新的一致性的概念,讨论不一致信念集的特征。在此基础上,本文讨论了本质上等价于三段论推理的标准规则,证明其是可靠和完备的。这也说明了,三段论推理可以在概念结构理论中有一个合理的解释。词项的同义是语言学中的重要问题,按整体论的观点,比同义更一般的不可分辨性更重要。本文给出了概念的不可分辨性的定义,并讨论其在语言中的表现。不同语言间的翻译也是语言学中的重要问题,本文在概念结构的形式理论基础上的对不同语言间的翻译进行了一些初步的讨论。本文只是在对最简单的语言进行讨论,通过这样的讨论体现概念结构形式理论的思想、方法和研究框架。     

文化神经科学：一个新兴的跨学科领域

文化神经科学是一个将文化,心理和大脑整合起来的新兴的跨学科领域。本文简要地介绍了从2000年到2010年在文化神经科学领域内的各种观点,同时回顾了该领域里一些典型的功能性磁共振（fMRI）的研究成果。文章认为,文化神经科学可为人类心理的研究提供一个全新的,整合性的理论框架,而且,它还为中国心理学家提供了机遇：使用中国被试开展文化神经科学研究去取得世界一流的成果。     

论儿童的心理理论与执行功能的关系

以错误 信念任务和表面 现实任务为主要测量手段的大量心理理论研究的结果表明,儿童的心理理论大约在4岁左右才能形成。儿童的心理理论为什么不能在4岁之前形成?研究者利用执行功能的缺乏来解释这种现象。研究表明,抑制控制、规则使用、工作记忆等可能均是与心理理论相关的一些执行成分,但这些观点均受到不同程度的质疑。因此,关于心理理论和执行功能的关系,还需要开展大量的后续研究。新近提出的关于"冷"执行功能和"热"执行功能的区分,也许是进一步探讨心理理论和执行功能关系的新途径。     

目标理论述评

目标理论是近年来成就动机研究领域的一个热点 ,学者们基于对目标概念、目标功能的不同理解 ,提出了各种目标理论。本文着重介绍了目标设置理论、动机系统理论和成就目标理论 ,剖析了不同学者对目标结构的性质、功能及其作用机制的理论观点。     

认同整合——自我和谐之路

认同整合(Identity integration)是认同研究领域的一个新的研究思路。认同整合是一个特质性的概念, 用于测量同时具有两(多)重不同身份认同者如何看待他们的两(多)重身份之间的关系的个体差异。个体可能认为他们所拥有的两(多)重身份是和谐统一的, 也可能认为这两(多)种身份之间是相互对立, 相互分离, 或者彼此冲突的。认同整合的概念已经被用于文化、种族和性别等领域的研究, 并被证明对文化适应、心理健康和创造性等有积极作用。但作为新概念, 需要深入探讨其作用机制及对其他相关领域的贡献, 尤其是探讨如何在中国背景下应用该概念来解决实际问题。     

Thoughtful Friends: Executive Function Relates to Social Problem Solving and Friendship Quality in Middle Childhood

Abstract

The present study examined links between best friendship quality, social problem solving in response to a transgression and conscious control of behavior (i.e., executive function or EF). Eighty-one 7- to 10-year-olds answered questions about their best friendship quality and responses to friendship transgressions (i.e., interpretations, goals, and strategies they would endorse). They also completed a battery of EF tasks measuring working memory, inhibition, and shifting. Results revealed few relations between social problem solving and best friendship quality. Social problem solving related to EF abilities, with inhibition relating to fewer revenge goals and cognitive flexibility relating to more neutral interpretations. Better working memory related to worse best friendship quality. Finally, verbal IQ was a strong predictor of several positive social problem-solving interpretations, goals, and strategies. Results suggest cognitive abilities in EF and language may be important to consider during middle childhood in this period of advancing social problem solving and friendships.     

顿悟:是进程监控还是表征转换

当前解释顿悟问题解决机制的理论主要有表征转换理论和进程监控理论。进程监控理论主要解释了顿悟问题为什么困难,但事实上它并没有说明顿悟问题为什么会解决,只回答了在什么情况下被试才会寻求其他的方法,而且它把顿悟问题解决的一般过程看成是同常规问题解决方法相同的过程。而表征转换理论主要解释了顿悟是如何获得的——顿悟的获得是由于问题解决者对问题的表征实现了正确的转变,但它并没有解释表征什么时候、怎么样才能转变?顿悟问题的解决经历了三个认知加工阶段,顿悟问题的解决需要在消除定势情况下激活正确的启发信息(线索),并验证了顿悟问题的原型激活和关键启发信息理论假说。     

Analogy as a strategy for supporting complex problem solving under uncertainty

Complex problem solving in naturalistic environments is fraught with uncertainty, which has significant impacts on problem-solving behavior. Thus, theories of human problem solving should include accounts of the cognitive strategies people bring to bear to deal with uncertainty during problem solving. In this article, we present evidence that analogy is one such strategy. Using statistical analyses of the temporal dynamics between analogy and expressed uncertainty in the naturalistic problem-solving conversations among scientists on the Mars Rover Mission, we show that spikes in expressed uncertainty reliably predict analogy use (Study 1) and that expressed uncertainty reduces to baseline levels following analogy use (Study 2). In addition, in Study 3, we show with qualitative analyses that this relationship between uncertainty and analogy is not due to miscommunication-related uncertainty but, rather, is primarily concentrated on substantive problem-solving issues. Finally, we discuss a hypothesis about how analogy might serve as an uncertainty reduction strategy in naturalistic complex problem solving.     

The Role of Executive Function in Arithmetic Problem-Solving Processes: A Study of Third Graders

This study investigated the roles of different executive function (EF) components (inhibition, shifting, and working memory) in 2-step arithmetic word problem solving. A sample of 139 children aged 8 years old and regularly attending the 3rd grade of primary school were tested on 6 EF tasks measuring different EF components, a reading task and a reading comprehension task, an arithmetic facts task evaluating basic knowledge of calculation, and three 2-step arithmetic word problems. Multiple hierarchical regression analyses were conducted to investigate the roles of the different EF components in the various phases of the problem-solving process. The results showed that EF affects the various phases of problem solving differently over and above calculation knowledge and reading abilities. The implications of these findings are discussed in relation to further understanding the role of cognitive skills in mathematical problem solving and in relation to instructional approaches that may increase children’s performance on 2-step arithmetic word problems.     

HAS PSYCHOLOGY A FUTURE?

I consider that psychologists have a duty to explore their own field, to create hypotheses about the behavior of animals, especially human, and to test these and look for possible causal relationships at the level of acting, thinking, perceiving humans m their environmental context Our agenda should be at this level, not one that depends on waiting for reductionist theories at some other level, be it neural, genetic, nuclear, or especially artificial To go about this work, a developmental approach, in a systems setting—the organism-environment system—holds great promise and has the dignity of successful precedents in other sciences
All of behavior—perceiving, acting, problem solving, communicating with others—should be our province The hallmarks of human behavior can and should be studied in all of these areas It IS their development that offers a road to understanding We should continue to look for theories of considerable generality, however elegant a model may be in a tiny realm If we tot find universal laws, we may still come up with unifying principles
Not so long ago, in another keynote address, George Miller told us that It was time to "give psychology away" (Miller, 1969) I am afraid that that is exactly what we are doing, though n the sense that Miller intended Let us keep psychology, recapture the old excitement, looking for the causes in behavior itself, and not giving up on the grand unified theory     

Structural equation modeling of approval voting data

The method of approval voting is a commonly used voting procedure in which each judge selects a subset of the alternatives. By postulating that the random utilities associated with the choice options in approval voting elections follow a multivariate normal distribution under the Thurstonian framework, Regenwetter, Ho, and Tsetlin (2007) attempted to integrate the normative theories and individual variabilities in modeling social behavior. However, their approach is limited to only three alternatives, due to computational intractability as the number of alternatives increases. In this article, we reparameterize extensions of their models under the structural equation modeling framework and propose the use of limited information methods for estimating model parameters. As a result, we are able to extend their previous approach to the analysis of approval voting data with any number of alternatives. Two applications are presented to illustrate the usefulness of such an approach.     

Maqasid al-Shariah as a Complementary Framework for Conventional Bioethics: Application in Malaysian Assisted Reproductive Technology (ART) Fatwa

Rapid development in the area of assisted reproductive technology (ART), has benefited mankind by addressing reproductive problems. However, the emergence of new technologies and techniques raises various issues and discussions among physicians and the masses, especially on issues related to bioethics. Apart from solutions provided using conventional bioethics framework, solutions can also be derived via a complementary framework of bioethics based on the Higher Objectives of the Divine Law (Maqasid al-Shariah) in tackling these problems. This approach in the Islamic World has been applied and localised in the Malaysian context. Thus, this paper highlights a conceptual theoretical framework for solving current bioethical issues, with a special focus on ART in the Malaysian context, and compares this theory with conventional theories of bioethics.     

How lay theories of prejudice shape prejudice confrontations: Examining beliefs about prejudice prevalence,origins, and controllability

The formative framework in prejudice confrontations research has focused on the utility of confrontations to activate one's self-regulation strategies to interrupt unintentional prejudice, discrimination, and stereotyping. As this framework remains dominant in the literature, little research has examined everyday people's theories about prejudice that diverge from this framework and accounted for these theories in investigating confrontation rates and outcomes. In this paper, we review key lay theories of prejudice and discuss the ways in which they may influence prejudice confrontations. First, we summarize lay theories regarding the prevalence, origins, and controllability of prejudice. Next, we consider how lay theories of prejudice may factor into the circumstances under which people confront prejudice, goals that people may hold when confronting, and outcomes of confronting for confronters and perpetrators. Throughout, we highlight fundamental research questions and hypotheses that integrate lay theories of prejudice and prejudice confrontations. We propose that better understanding lay theories of prejudice and how they influence prejudice confrontations may help to advance translational and theoretical research in social psychology.     

Systemic therapy and attachment narratives

In this paper we describe how we bring together three major systems of thought: attachment theory; family systems theories; and theories of narrative development, in an integrated approach to systemic practice that we call attachment narrative therapy (ANT). ANT provides a four‐stage framework for practice: creating a secure base; exploring narratives and attachment experiences within a systemic framework; considering alternatives and taking action; and the future and maintenance of the therapeutic base. Formulation, especially regarding the role of emotions and attachments in family dynamics and narratives, is at the heart of our approach and helps us hold ourselves accountable for our particular weave of theory and practice.
