视知觉神经心理障碍的内隐和外显加工分离及其神经基础

外显和内隐认知功能区别的关键是有无意识觉察的出现,脑损伤神经心理障碍为探讨内隐/外显加工的“纯净”分离提供了可能。通过对典型的视知觉神经障碍中的盲视、认识不能、单侧忽视的内隐和外显加工分离的实验证据及其神经基础的探讨,证明了视知觉神经心理障碍的内隐加工完好和外显加工损伤之间的分离,说明内隐和外显加工有着不同的神经基础,但这种分离的神经基础是什么以及这种分离的本质还有待于进一步的研究。视知觉神经心理障碍的内隐/外显加工的反向损伤是没有进行研究的领域。     

Dream actors in the theatre of memory: Their role in the psychoanalytic process2

The author notes that neuropsychological research has discovered the existence of two long‐term memory systems, namely declarative or explicit memory, which is conscious and autobiographical, and non‐declarative or implicit memory, which is neither conscious nor verbalisable. It is suggested that pre‐verbal and pre‐symbolic experience in the child's primary relations is stored in implicit memory, where it constitutes an unconscious nucleus of the self which is not repressed and which influences the person's affective, emotional, cognitive and sexual life even as an adult. In the analytic relationship this unconscious part can emerge essentially through certain modes of communication (tone of voice, rhythm and prosody of the voice, and structure and tempo of speech), which could be called the ‘musical dimension’ of the transference, and through dream representations. Besides work on the transference, the critical component of the therapeutic action of psychoanalysis is stated to consist in work on dreams as pictographic and symbolic representations of implicit pre‐symbolic and pre‐verbal experiences. A case history is presented in which dream interpretation allowed some of a patient's early unconscious, non‐repressed experiences to be emotionally reconstructed and made thinkable even though they were not actually remembered.     

The explicit and implicit dance in psychoanalytic change

How the implicit/non-declarative and explicit/declarative cognitive domains interact is centrally important in the consideration of effecting change within the psychoanalytic arena. Stern et al. (1998) declare that long-lasting change occurs in the domain of implicit relational knowledge. In the view of this author, the implicit and explicit domains are intricately intertwined in an interactive dance within a psychoanalytic process. The author views that a spirit of inquiry (Lichtenberg, Lachmann & Fosshage 2002) serves as the foundation of the psychoanalytic process. Analyst and patient strive to explore, understand and communicate and, thereby, create a 'spirit' of interaction that contributes, through gradual incremental learning, to new implicit relational knowledge. This spirit, as part of the implicit relational interaction, is a cornerstone of the analytic relationship. The 'inquiry' more directly brings explicit/declarative processing to the foreground in the joint attempt to explore and understand. The spirit of inquiry in the psychoanalytic arena highlights both the autobiographical scenarios of the explicit memory system and the mental models of the implicit memory system as each contributes to a sense of self, other, and self with other. This process facilitates the extrication and suspension of the old models, so that new models based on current relational experience can be gradually integrated into both memory systems for lasting change.     

REVISING PSYCHOANALYTIC INTERPRETATIONS OF THE PAST

The author reviews a contemporary cognitive psychology perspective on memory that views memory as being composed of multiple separate systems. Most researchers draw a fundamental distinction between declarative/explicit and non-declarative/implicit forms of memory. Declarative memory is responsible for the conscious recollection of facts and events - what is typically meant by the everyday and the common psychoanalytic use of the word 'memory'. Non-declarative forms of memory, in contrast, are specialised processes that influence experience and behaviour without representing the past in terms of any consciously accessible content. They operate outside of an individual's awareness, but are not repressed or otherwise dynamically unconscious. Using this theoretical framework, the question of how childhood relationship experiences are carried forward from the past to influence the present is examined. It is argued that incorporating a conceptualisation of non-declarative memory processing into psychoanalytic theory is essential. Non-declarative memory processes are capable of forming complex and sophisticated representations of the interpersonal world. These non-declarative memory processes exert a major impact on interpersonal experience and behaviour that needs to be analysed on its own terms and not mistakenly viewed as a form of resistance.     

内隐与外显记忆编码阶段脑机制的重叠与分离

记忆包括编码和提取两个重要阶段, 以往研究多关注内隐和外显记忆在提取阶段的脑机制分离, 那二者在编码阶段的脑机制是否不同？为探讨这个问题, 该实验采用两阶段的迫选再认方式, 把学习项目区分成三类：随后被选择且告知为见过的项目(记住), 随后被选择但告知为猜测的项目 (启动)以及随后未被选择的项目(忘记)。结果表明, 从200 ms开始的颞区负走向Dm效应为内隐记忆(启动vs忘记)所特有, 反映了对刺激的知觉加工过程, 400~500 ms前额区正走向的Dm效应为外显记忆(记住vs忘记)所特有, 反映了对刺激的精细加工过程, 而200~300 ms中央区及600 ms开始的顶区负走向的Dm效应为两种记忆类型所共有, 它们分别反映了对刺激的注意状态以及把编码后的刺激信息登记进相应记忆系统的过程。因此, 内隐记忆与外显记忆在编码阶段的脑机制既存在着分离, 也存在着重叠的现象。     

态度研究的新进展——双重态度模型

态度一直是社会心理学领域一个极为重要的研究课题,一直以来研究只关注有意识状态下人们的外显态度,对于无意识状态下的内隐态度最近才引起人们的意识。双重态度模型理论认为,人们对同一态度客体可能同时拥有两种不同的态度－－外显态度和内隐态度,这一理论对传统的态度概念及测量技术都提出了新的挑战。该对双重态度模型的理论来源、基本观点、双重态度类型及相关的研究证据作了详细介绍,最后探讨了双重态度模型理论对态度改变、态度测量及态度与行为一致性等未来研究方向的意义与启示。     

New approaches to understanding unconscious processes: Implicit and explicit memory systems

Abstract

Freud viewed the unconscious as being roughly equivalent to dynamically repressed wishes, needs, and motivations. Findings from developmental psychology, cognitive psychology, psychoanalysis, and neuroscience over the past 40 years have dramatically changed our views of unconscious processes and the human mind. It is now clear that Freud's dynamic unconscious is only a minor segment of information that is processed at subsymbolic, implicit, and automatic levels. Only a fraction of this information is further processed at explicit conscious levels. Moreover, the vast majority of the information that remains nonconscious is adaptive and has major consequences for development. We examine some clinical implications of these views.     

学优生与学困生内隐与外显协同学习的比较研究

根据目前国内采用的标准,选取学优生和学困生各120人。运用内隐学习中的双条件人工语法材料和强分离的实验范式,考察和比较了两种学生的内隐学习、内隐与外显协同学习的成绩。结果显示:(1)学优生在外显学习、协同学习(先内隐后外显以及内隐与外显交替)方式下的成绩显著好于学困生,而在内隐学习方式下,二者成绩差异不显著。(2)学优生的外显学习及协同学习成绩显著好于内隐学习成绩,而学困生在四种学习方式下成绩差异不显著。表明在人工语法学习中学优生的有意识学习及其与无意识的协同学习效果较好,而学困生的有意识学习及协同学习较差。     

认知疲劳效应对内隐记忆与外显记忆的影响

本研究通过比较内隐记忆与外显记忆受到认知疲劳影响的情况,以了解内隐记忆的自动化加工机制。实验采用被试内设计,使用词汇判断与词汇再认任务测量内隐记忆与外显记忆。实验结果发现,相对于控制组,疲劳组的被试在完成疲劳任务后内隐记忆成绩显著下降,而外显记忆没有受到影响。结果说明相对于外显记忆,内隐记忆更容易受到认知疲劳影响。内隐记忆虽然是无意识的认知加工,但是与其他自动化加工具有不同的特征。     

人工语法学习中意识加工的渐进发展

内隐学习研究致力于探讨学习活动的意识加工程度, 当前相关的研究逻辑从传统的意识二分观转向渐进意识假设。本研究通过对人工语法范式进行改造, 并借鉴加工分离程序的有关思想, 在学习阶段引入双重测量任务, 并根据双重任务成绩计算分离出相应学习时段的意识与无意识成分的贡献分数, 从而考察在内隐学习过程中两种加工成分的动态变化特征。研究结果支持渐进意识假设, 在学习进程中, 无意识成分和意识成分都呈现出渐进发展的趋势; 而随学习的深入, 两种成分呈现出不同的变化模式, 中后期意识加工快速增长, 无意识加工则保持平缓发展, 渐进意识系统整体呈现向外显学习推进的发展态势。

Working memory moderates the effect of the integrative process of implicit and explicit autonomous motivation on academic achievement

In previous research, autonomous motivation (AM) has been found to be associated with school achievement, but the relation has been largely heterogeneous across studies. AM has typically been assessed with explicit measures such as self‐report questionnaires. Recent self‐determination theory (SDT) research has suggested that converging implicit and explicit measures can be taken to characterize the integrative process in SDT. Drawing from dual‐process theories, we contended that explicit AM is likely to promote school achievement when it is part of an integrated cognitive system that combines easily accessible mental representations (i.e., implicit AM) and efficient executive functioning. A sample of 272 university students completed a questionnaire and a lexical decision task to assess their explicit and implicit AM, respectively, and they also completed working memory capacity measures. Grades were obtained at the end of the semester to examine the short‐term prospective effect of implicit and explicit AM, working memory, and their interaction. Results of moderation analyses have provided support for a synergistic interaction in which the association between explicit AM and academic achievement was positive and significant only for individuals with high level of implicit AM. Moreover, working memory was moderating the synergistic effect of explicit and implicit AM. Explicit AM was positively associated with academic achievement for students with average‐to‐high levels of working memory capacity, but only if their motivation operated synergistically with high implicit AM. The integrative process thus seems to hold better proprieties for achievement than the sole effect of explicit AM. Implications for SDT are outlined.     

Implicit Mental Processes in Ethical Management Behavior

This article examines the relationship between implicit mental processes and ethical decisions made by managers. Based on the dual-process view in social and cognitive psychology, it is argued that social cognition (e.g., moral judgments) can rely on two different modes of information processing. On one hand, moral judgments reflect explicit, conscious, and extensive cognitive processes, which are attributed to explicit attitude. On the other hand, moral judgments may also be based on implicit, automatic, and effortless processes referring to implicit attitude. To test this thesis, a study involving 182 participants was conducted. The results support the thesis.     

A theory of implicit and explicit knowledge

The implicit-explicit distinction is applied to knowledge representations. Knowledge is taken to be an attitude towards a proposition which is true. The proposition itself predicates a property to some entity. A number of ways in which knowledge can be implicit or explicit emerge. If a higher aspect is known explicitly then each lower one must also be known explicitly. This partial hierarchy reduces the number of ways in which knowledge can be explicit. In the most important type of implicit knowledge, representations merely reflect the property of objects or events without predicating them of any particular entity. The clearest cases of explicit knowledge of a fact are representations of one's own attitude of knowing that fact. These distinctions are discussed in their relationship to similar distinctions such as procedural-declarative, conscious-unconscious, verbalizable-nonverbalizable, direct-indirect tests, and automatic-voluntary control. This is followed by an outline of how these distinctions can be used to integrate and relate the often divergent uses of the implicit-explicit distinction in different research areas. We illustrate this for visual perception, memory, cognitive development, and artificial grammar learning.     

内隐/外显不同水平攻击者的注意偏向：行为和ERP证据

通过行为实验（点探测）和ERP实验（情绪Stroop）两个实验任务,考察了内隐/外显不同水平攻击者的注意偏向及其脑机制。结果表明：高外显攻击者对愤怒面孔存在注意偏向;高外显攻击者在愤怒面孔上的N100波幅显著低于中性面孔,表明其注意分配和调节能力较弱;高外显攻击者较之低外显攻击者的P300波幅更小表明其存在注意等方面的认知加工缺陷,N400波幅更小表明其对愤怒面孔进行语义编码时加工更为流畅;外显攻击组与内隐攻击组在FCz和Cz电极点上不同。这为内隐/外显攻击二者有着独立结构提供了行为与认知神经科学的证据。     

自然科学概念形成过程中外显与内隐学习的比较

本研究选取真实的自然科学概念来对概念形成过程及其中的外显与内隐学习进行实验性探索．证明了自然科学概念形成过程中内隐学习的存在;阐释了概念形成过程中内隐学习的效率可与外显学习不相上下;揭示了真实的自然科学概念形成过程是由渐进期——高原期——突变期三个阶段构成的．不论外显学习还是内隐学习,接近真理的路径十分相似,并且没有显著的性别差异;此外还发现自然科学概念的内隐学习可以有效地用语言启动。本研究结果对心理学和自然科学教学均有理论价值与实践意义。     

Freud's 'problem': COGNITIVE NEUROSCIENCE & PSYCHOANALYSIS WORKING TOGETHER ON MEMORY

The first part of this paper discusses the development of Freud's views on memory from the time of the Project up to the formulation of the second topography. Freud's attempts to match his psychological views with an organic model were necessarily inconclusive, but in the process many innovative ideas about memory can be seen to resonate with recent developments in cognitive neuroscience. A brief discussion of perceptual identity, internal perception and Freud's affect theory introduce the central theoretical idea in the second half of the paper, namely that Identification can be seen as a form of memory. Modern memory theory is linked with the superego, following which the author proposes that internal objects might be renamed 'memory-objects' and that these can be understood in terms of the distinction made in cognitive neuroscience between implicit and explicit memory and between different parts of the brain, in particular the amygdala, the basal ganglia and the hippocampus. Klein's 'memory in feeling' and the views of Fairbairn and Ogden in relation to the dynamic nature of internal objects are briefly discussed. The paper ends with a few comments on the aberrations of memory and some implications of the implicit memory-object system.     

人格特质与外显自尊和内隐自尊的关系

自尊被认为与人格特质之间存在紧密的联系。近年来社会认知研究领域发现,在传统“外显自尊”以外,个体还存在一个“内隐自尊”结构。由于中国人格结构与西方“大五”人格结构存在系统性的差异,本研究试图考察在中国文化下个体的人格特质与自尊水平之间的关系。结果发现,外显自尊主要与中国人人格结构中的“自我指向”的人格特点关系紧密;内隐自尊作为一个独立于外显自尊的内隐态度结构,与各个人格特质不存在显著的相关     

Category and stereotype activation revisited

In Study 1 (N= 230), we found that the participants' explicit prejudice was not related to their knowledge of cultural stereotypes of immigrants in Sweden, and that they associated the social category immigrants with the same national/ethnic categories. In Study 2 (N= 88), employing the category and stereotype words obtained in Study 1 as primes, we examined whether participants with varying degrees of explicit prejudice differed in their automatic stereotyping and implicit prejudice when primed with category or stereotypical words. In accord with our hypothesis, and contrary to previous findings, the results showed that people's explicit prejudice did not affect their automatic stereotyping and implicit prejudice, neither in the category nor stereotype priming condition. Study 3 (N= 62), employing category priming using facial photographs of Swedes and immigrants as primes, showed that participants' implicit prejudice was not moderated by their explicit prejudice. The outcome is discussed in relation to the distinction between category and stereotype priming and in terms of the associative strength between a social category and its related stereotypes.
