Understanding implicit memory. A cognitive neuroscience approach.

Dissociations between implicit and explicit memory have attracted considerable attention in recent memory research. A central issue concerns whether such dissociations require the postulation of separate memory systems or are best understood in terms of different processes operating within a single system. This article presents a cognitive neuroscience approach to implicit memory in general and the systems-processes debate in particular, which draws on evidence from research with brain-damaged patients, neuroimaging techniques, and nonhuman primates. The article illustrates how a cognitive neuroscience orientation can help to supply a basis for postulating memory systems, can provide useful constraints for processing views, and can encourage the use of research strategies that the author refers to as cross-domain hypothesis testing and cross-domain hypothesis generation, respectively. The cognitive neuroscience orientation suggests a complementary role for multiple systems and processing approaches.     

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。

Memories, fantasies, archetypes: an exploration of some connections between cognitive science and analytical psychology

The value of cognitive science as a means of investigating psychodynamic theory and practice is discussed and the limitations of this approach are described. Research findings from cognitive science are drawn on to clarify the nature of memory, which is seen to be a mixture of reproduction and reconstruction and the concepts of true and false memory are explored in this light. The part played by implicit memory and internal working models in producing transference is also examined. New ways of conceptualizing fantasy, which describes it as another facet of internal working models, and the role of transgenerational transmission of attachment patterns in creating internal working models are explored. The nature of archetypes is considered in the light of cognitive science research and a minimalist model is proposed, in which they can be likened to image schemas, that is, primitive conceptual structures that exist in a form which can never be experienced directly or indirectly.     

The relevance of attachment theory to a contemporary Jungian view of the internal world: internal working models, implicit memory and internal objects

In this paper I examine the various meanings of the term 'internal object' and the differences between various theoretical models for the formation of internal objects. I suggest that the idea in attachment theory of 'internal working models' emphasizes the internal world as one consisting of unconscious internalized patterns of emotional relationships. The term 'internal object' lacks this clarity and the different meanings it carries within differing theoretical frameworks are a source of confusion. I describe the role implicit memory plays in the formation of 'internal working model's and suggest that these offer us an alternative explanation for unconscious fantasy and for object relationships to that of instinctual drives. This model is then brought to bear on contemporary Jungian concepts of the internal world, with a suggestion that, seen in this light, Jung's formulation of the concept of the complex has many features in common with the 'internal working model' of attachment theory.     

客体工作记忆研究的现状与展望

近年来, 大量的研究分别从行为和认知神经心理学的角度探讨了客体工作记忆的特性。行为水平上, 相关研究主要集中在客体工作记忆研究范式、客体在视觉工作记忆中的存储方式、视觉工作记忆容量等方面, 而客体工作记忆存储的争论体现在客体工作记忆存储的“强捆绑”假设、“特征-捆绑统一存储”假设、双重存储机制假设, 以及客体的捆绑等方面。认知神经水平上, 颞叶、枕叶和顶叶在视觉工作记忆中的作用不同, 顶叶、颞叶和前额叶在工作记忆特征捆绑和加工中起重要作用。     

Reconsidering therapeutic action: Loewald, cognitive neuroscience and the integration of memory's duality

Both Loewald's relational theory of memory and the Self-Memory System (SMS) of cognitive neuroscience describe a dual memory system, one system that is experience-near sensory-perceptual, and the other, symbolic and conceptual. In contrast to perspectives that locate therapeutic action in either altering implicit procedural memories or interpreting explicit historical content, we argue that psychological health emerges from effective integration of both memory systems, achieved through a combination of transference dynamics and analytic insight. We support this position by elaborating four key assumptions of the loewaldian and SMS perspectives, followed by application to a clinical example. We highlight the power of certain integrative autobiographical memories called 'self-defining memories' in assisting an understanding of transference dynamics and providing metaphoric touchstones to guide subsequent treatment.     

工作记忆对知觉类别学习的影响:问题与构想

人们学习将感知到的客体按照不同的标准或规则分类存储,即类别学习。而工作记忆作为多种认知加工的基础,对类别学习具有重要作用。基于已有研究,分别梳理了言语工作记忆和视空工作记忆对基于规则和信息整合类别结构的影响。目前,执行功能是否影响内隐类别学习系统、工作记忆负荷对内隐外显类别学习系统的影响是否一致还存在争议。此外,工作记忆影响知觉类别学习的认知加工阶段尚不清晰。未来的研究还需明确工作记忆负荷对内隐和外显类别学习的影响,进一步验证工作记忆影响类别学习的认知加工阶段假设的合理性。     

内隐记忆的启动效应

启动效应是指先前经验对当前任务的促进作用。启动效应的研究是内隐记忆研究的重要组成部分。该文对启动效应在认知行为研究、脑损伤患者的神经心理学研究以及功能成像研究方面取得的新进展进行了回顾。在简要评述启动效应研究中存在的问题基础上,对于启动效应研究中的进一步发展,指出建立清晰的概念和构建更有解释效力的理论模型的迫切需要     

The repressed and implicit knowledge

The distinction between implicit (non-conscious) and explicit (conscious) knowledge made by cognitive scientists is applied to the psychoanalytic idea of repressed contents. The consequences of repression are suggested to have been caused by implicit representations. Repressed memories can also be treated in terms of explicit representations, which are prevented from becoming activated. Implicit knowledge cannot, however, be made conscious, and thus the idea of becoming conscious of the repressed desires and fears that have never been conscious is contradictory. This tension may be relieved by reconceptualising the idea of becoming conscious of the repressed. It is suggested that this could be seen as creating explicit knowledge about the effects of implicit representations. By applying the implicit/explicit knowledge distinction, psychoanalytic ideas concerning the repressed could be connected to current views in the domain of cognitive orientation.     

Determinants of memory development in childhood and adolescence

Research on the development of memory has a long history and constitutes one of the most active research areas in the field of cognitive development. In this article, we first describe major historical developments in the literature on children's memory, focusing on systematic research that began in the late 1960s. We then examine new developments in the field, describing four important lines of inquiry: (a) the development of implicit memory, (b) short‐ and long‐term memory development in infancy, (c) longitudinal research on memory strategies and metamemory, and (d) developmental cognitive neuroscience of memory. Finally, promising lines of future research on memory development are briefly discussed.     

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.     

提取干扰对不同类型内隐记忆的影响

以往研究关于提取阶段的干扰是否会影响内隐记忆存在着异义, 其中一个重要因素可能源于所采用的内隐记忆测验类型的差异。本研究采用学习-测验范式, 通过4个实验, 分别考察了提取干扰对识别式知觉内隐测验、识别式概念内隐测验、产生式知觉内隐测验和产生式概念内隐测验的影响, 以期对提取干扰和内隐记忆之间的关系有着更全面的了解。结果表明: (1)词汇判断任务(识别式知觉)和语义分类任务(识别式概念)的启动效应在提取干扰下消失了, (2)而产生式词汇判断任务(产生式知觉)和产生式语义分类任务(产生式概念)在提取干扰下仍发现了明显的启动效应, 但与无干扰条件相比, 启动效应量也有着明显的减少。由此可见, 不同类型的内隐记忆都会受到提取干扰的影响, 相比于产生式启动, 识别式启动更容易受到提取干扰的破坏。     

Influence of object size on baseline identification, priming, and explicit memory

We investigated the influence of size on identification, priming, and explicit memory for color photos of common objects. Participants studied objects displayed in small, medium, and large sizes and memory was assessed with both implicit identification and explicit recognition tests. Overall, large objects were easier to identify than small objects and study-to-test changes in object size impeded performance on explicit but not implicit memory tests. In contrast to previous findings with line-drawings of objects but consistent with predictions from the distance-as-filtering hypothesis, we found that study-test size manipulations had large effects on old/new recognition memory test for objects displayed in large size at test but not for objects displayed small or medium at test. Our findings add to the growing body of literature showing that the findings obtained using line-drawings of objects do not necessarily generalize to color photos of common objects. We discuss implications of our findings for theories of object perception, memory, and eyewitness identification accuracy for objects.     

简评认知神经科学取向的智力观

随着认知神经科学与生物技术的发展,现当代智力理论的构建明显地受到其影响。这些智力理论被称之为认知神经科学取向的智力观,如Garlick的神经可塑性模型;Das等人根据Luria的神经模型提出的智力PASS模型;Kaufman提出的儿童评估成套测验（K-ABC）;Ceci的生物-生态学智力模型及Perkins的真智力理论等。这些智力观都直接将认知神经过程或神经生物学的某些研究成果融合于其理论模型之中。认知神经科学取向的智力观为智力研究提供了新的研究视角和思考维度,但同时也可能面临某种发展困境。第二代认知科学的具身认知思想可能是解决传统身-心争论的有效途径。     

The influence of visual short-term memory on size perception

We show that perceived size of visual stimuli can be altered by matches between the contents of visual short-term memory and stimuli in the scene. Observers were presented with a colour cue (to hold in working memory or to merely identify) and subsequently had to indicate which of the two different-coloured objects presented simultaneously on the screen appeared bigger (or smaller). One of the two objects for size judgements had the same colour as the cue (matching stimulus) and the other did not (mismatching stimulus). Perceived object size was decreased by the reappearance of the recently seen cue, as there were more size judgement errors on trials where the matching stimulus was physically bigger (relative to the mismatching stimulus) than on trials where the matching stimulus was physically smaller. The effect occurred regardless of whether the visual cue was actively maintained in working memory or was merely identified. The effect was unlikely generated by the allocation of attention, because shifting attention to a visual stimulus actually increased its perceived size. The findings suggest that visual short-term memory, whether explicit or implicit, can decrease the perceived size of subsequent visual stimuli.     

Surviving in absence--on the preservative and death drives and their clinical utility

This paper offers a new theoretical and clinical look at the death drive in connection with the preservative drive. The author elaborates the flaws she sees in Freud's Beyond the Pleasure Principle (1920) and reformulates the transition between Freud's first drive theory and his second one within an implicit object relations theory. Simultaneously with this revised version of drive theory, a structural theory for the realm of healthy self- and object preservation and for pathological or deadened self and object parts is developed, including the devastating effects of trauma. Clinical material from an extended psychoanalysis shows how these concepts can help us understand these patients' absence and "deadness" and rethink the technical challenges they provide.

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.
