自我情绪一致性效应及其可逆性:探究负荷理论

认知资源系统是单一的,还是多重的?根据不同脑区调节自我积极、消极信息加工这一脑成像研究结果,本研究通过验证自我情绪一致性效应(自我积极、消极工作记忆负荷干扰同类认知任务,而不干扰不同类认知任务)及其可逆性,考察这一争议。两个实验采用改编的阅读广度范式,通过操纵工作记忆负荷类型,证实了该效应的存在;通过控制认知任务的加工速度,发现了该效应的可逆性。研究结果支持了多重资源的观点。     

视听通道双任务对多目标追踪的影响:干扰还是促进?

通过3个实验分别考察了视觉和听觉任务对同时进行的多目标追踪任务干扰程度的差异,以及当视觉与听觉任务的信息加工与多目标追踪的身份特征相一致时,视觉与听觉任务是否会对多目标追踪产生促进作用。在控制眼动的情况下,听觉任务对多目标追踪的干扰程度大于视觉任务;而在不控制眼动的情况下,听觉任务对多目标追踪的干扰程度小于视觉任务。说明多目标追踪过程既要占用编码阶段的视觉注意资源,又要占用中央加工阶段的中央注意资源。当视觉或听觉数字判断任务中的数字与多身份追踪任务中目标的数字身份相一致时,该相容性会对追踪表现产生促进作用并降低两任务间的干扰程度。这是由于追踪过程中目标的数字身份被储存在视觉工作记忆中,节约了用于数字加工的认知资源,从而促进了两项任务的表现。最后,对多目标追踪中的注意分配机制进行了讨论。     

情绪对认知加工的影响：事件相关脑电位系列研究

为探讨情绪与认知的相互作用关系及其脑机制,建立了情境图片、面孔、汉字和声音四个系列组成的中国情感刺激材料库,并通过ERP实验对情绪与注意、工作记忆的关系以及特质焦虑者的认知特点进行了研究。结果发现：⑴ 负性情绪刺激在信息加工过程中至少在注意、评价及反应准备这几个阶段具有某种优先权,注意偏向也可在内隐任务下发生,负性刺激对注意资源不足具有某种补偿作用;⑵ 威胁性视觉提示对其后的视觉加工具有调节作用,高焦虑个体对这类性刺激投入了更多的视觉加工资源,而且威胁性刺激对注意的影响可以跨通道进行,威胁性的视觉刺激可以影响触觉注意;⑶ 在情绪对工作记忆的影响方面,负性情绪下空间工作记忆任务引起的P300波幅减小,这种效应可能是基于情绪对顶叶注意系统的调节作用,而在词语工作记忆任务中这种效应消失     

孤独症谱系障碍者的视觉-空间工作记忆缺陷及脑机制

孤独症谱系障碍(ASD)个体存在视觉-空间工作记忆加工缺陷,主要表现在4个方面,即随认知负荷增大而缺陷加重、工作记忆容量不足、工作记忆加工过程中的注意功能失调和对刺激进行整体组织的能力缺乏。神经机制研究显示,ASD个体存在明显的额-顶工作记忆网络激活异常,以及相关脑区的脑结构、白质连接异常。另外,作为基础性的认知加工过程,ASD个体的视觉-空间工作记忆各加工环节与言语工作记忆、执行功能、社会认知等因素均存在交互影响。纵观目前研究成果,未来研究可从研究手段、机制探究和干预训练三方面入手,着眼于研究方法的生态化和多元化,揭示客体和空间工作记忆的机制分离,并着力开发更具针对性的干预训练模式。     

基本心理能力老化的认知机制

基本心理能力老化机制是认知老化领域研究热点之一。横断研究与追踪研究表明, 感觉功能、加工速度、工作记忆等信息加工资源的衰退导致了基本心理能力的衰退。但由于相关研究不能进行因果推论, 基本心理能力老化的认知机制尚存在争论。因此本项目拟采用实验室研究和干预实验设计, 通过操纵感觉功能(知觉压力水平)、干预加工速度与工作记忆, 考察基本心理能力的年龄差异的变化, 以期为认知老化理论的深化和拓展提供实验依据。     

认知分心的强度对创伤性信息加工的影响

结合ERP技术、创伤电影范式和改进的工作记忆范式探讨了认知分心的强度对创伤性信息加工的影响。结果发现, (1)高负荷上的N2波幅显著大于低负荷上的。(2)在低工作记忆负荷上, 创伤负性图引发的LPP波幅显著大于创伤中性图和无关中性图; 而在高工作记忆负荷上, 三类图片引发的LPP波之间差异不再显著。(3)在创伤负性图上高、低负荷工作记忆任务诱发的LPP波差异显著, 且高负荷条件下的LPP波幅显著小于低负荷条件。结果表明, 相比低认知控制, 早期高认知控制对创伤性信息的调节更有效, 支持了认知控制理论。     

视觉工作记忆负载类型对注意选择的影响

通过操纵Flanker任务相对于视觉工作记忆任务的呈现位置, 探讨在视觉工作记忆编码和保持阶段, 精度负载和容量负载对注意选择的影响。行为结果发现, Flanker任务呈现位置和视觉工作记忆负载类型影响注意选择; ERP结果发现, 在保持阶段, 当搜索目标和干扰项不一致时, 负载类型影响N2成分。研究表明, 在编码阶段, 视觉工作记忆负载主要通过占用更多知觉资源降低干扰效应, 支持知觉负载理论; 而在保持阶段, 当Flanker任务位于记忆项内部时, 两类负载在工作记忆表征过程中不同的神经活动导致投入到注意选择的认知控制资源不同, 可能是两类负载影响保持阶段注意选择的机制。     

工作记忆负荷、形状干扰对聋人与听力正常人注意捕获影响的眼动研究

通过记录和分析被试的行为和眼动指标,本研究试图探讨不同工作记忆负荷下,形状干扰对聋人与听力正常人不同视野位置上刺激信息捕获注意的异同。研究结果表明：（1）形状干扰刺激虽然没有影响被试视觉加工的认知绩效,但被试的眼动模式会由于工作记忆负荷的改变而改变,高工作记忆负荷时,有形状干扰的注视次数高于无形状干扰。（2）工作记忆负荷、视野位置影响被试视觉加工任务的完成,被试在不同视野位置的加工过程表现出不一致的眼动模式。（3）聋人视觉加工在高工作记忆负荷时存在一定的劣势,但其对不同视野位置的信息加工及形状干扰所产生的注意捕获效应与听力正常人一致。     

重新检视工作记忆在视觉搜索中的作用

视觉搜索是人类从作用于视觉系统的大量信息中选择相关信息进入信息加工系统的一种认知功能, 同时也是研究选择性注意的一种常用范式。工作记忆作为一种服务于当前任务信息的存储与加工的认知系统, 在视觉搜索过程中扮演着关键角色。为了深入了解工作记忆在视觉搜索过程中的作用机制, 在梳理已有成果的基础上, 分别从工作记忆对靶子模板的储存、视觉搜索项目与靶子模板在工作记忆中的匹配及工作记忆对已检测过搜索项目的记忆三个方面进行综述。最后结论表明工作记忆确实在视觉搜索过程中起作用, 但其作用机制仍存在较多争议。     

基于工作记忆内容的视觉注意

视觉系统是一个资源有限的信息加工系统, 在任何时刻视觉注意只能选择外界环境中的有限信息进行加工。工作记忆对于解决视觉场景中不同物体之间的注意竞争具有重要作用, 保持在工作记忆中的物体表征会以自上而下的方式引导注意优先选择视场中与之匹配的物体。本文系统回顾了有关工作记忆内容对视觉注意的引导作用的研究文献, 并探讨了基于工作记忆内容的视觉注意捕获的自动性, 指出基于工作记忆内容的视觉注意捕获是一个有条件的自动化过程。     

Together – apart: in touch in a time of separation

This paper explores the experience of working as a Jungian analyst through the various phases of the global COVID-19 pandemic, examining the importance of the physical containing space alongside the analyst’s internal mind and how technology can both help and hinder understanding. A number of clinical vignettes illustrate the challenge of communicating over a distance, paying particular attention to the way countertransference phenomena can become re-attuned. Reference is made to mythology and symbols of hope, and consideration given to the meaning and purpose of the pandemic.     

The Possibility of Meaning in Human Evolution

Science undermines the certitude of non-naturalistic answers to the question of whether human life has meaning. I explore whether evolution can provide a naturalistic basis for existential meaning. Using the work of philosopher Daniel Dennett and scientist Ursula Goodenough, I argue that evolution is the locus of the possibility of meaning because it has produced intentionality, the matrix of consciousness. I conclude that the question of the meaning of human life is an existentialist one: existential meaning is a product of the individual and collective tasks human beings undertake.     

Phenotypic plasticity and archetype: a response to common objections to the biological theory of archetype and instinct

Since Jung’s death in 1961, scholars have attempted to integrate growing biological science data into Jungian concepts such as the collective unconscious, instincts and the archetypes. This enterprise has been challenging due to persistent false dichotomies of gene and environment occasionally arising. Recent works by Roesler (2022a, 2022b) for example, have raised objections to the biological theory of archetypes, but the objections are plagued by such dichotomies. The concept of phenotypic plasticity, however, helps to both avoid this problem as well as bridge the gap between competing theories into a more integrated model with solid biological foundations.     

When is it time to stop? When good enough becomes bad enough

This article draws on Winnicott’s concept of the good enough mother to discuss how to know whether a therapeutic situation is good enough to continue or bad enough to end. This dilemma is explored in terms of clinical syndromes, such as anorexia and pathological gambling, but focuses mainly on analyst-initiated endings, which are termed the ‘Casablanca dilemma’, based on an amplification of the ending of the film Casablanca. The author goes on to discuss such one-sided endings, drawing on interviews with 40 analysts and therapists about their clinical experience. A typology of bad enough endings is presented. The psychological differences between a good enough analysis as opposed to a bad enough one are explored through the ideas of Winnicott and Neumann.     

Kann Es Ein Argument Für Den Skeptizismus Geben? Das Epistemische Problem Der Irrtumsmöglichkeit

Summary  Is there any argument for scepticism? The epistemic problem of the possibility of error. Arguments for scepticism rest on the assumption that knowledge claims are fallible. For this reason the concept of knowledge appears to be questionable. Since it is necessary to distinguish doubts from possible doubts, the arguments for scepticism appear to be unconvincing. If we take it into account that we know something that is immune to doubt, we should draw the conclusion that, contrary to scepticism, knowledge claims have to be compatible with being fallible. Thus any knowledge claim is capable of being doubted.     

The transcendent function in Spitteler’s Prometheus and Epimetheus

In August 2020, John Beebe and Steve Myers met via Zoom to discuss their differing interpretations of psychological typology and the different sources within Jung’s writings that influenced their books: Integrity in Depth: Energies and Patterns in Psychological Type (Beebe), and Myers-Briggs Typology vs Jungian Individuation (Myers). The discussion centred on Spitteler’s epic poem Prometheus und Epimetheus, which forms the basis of chapter V of Psychological Types. This is both the largest chapter and one of two chapters that Jung highlighted in the Argentine foreword as containing the essence of the book. Jung’s book is primarily about the transformation of personality rather than the categorization of people. Although it contains a critical psychology that deconstructs the nature of consciousness, that is only one half of the book and a stepping-stone to the other half, which is the reconciliation of opposites with particular emphasis on the relation of consciousness and the unconscious. Jung assumed that readers were already familiar with Prometheus und Epimetheus, an understanding of which sheds light on the nature of the transformation that Jung described – the development of a new attitude towards attitude itself.

Seeing in the Dark: A View into Dissociation and Healing

In this paper, I will explore the role of art-making, the experience of trauma and dissociation, and the process of working with self-states from an analytic and creative frame. Relevant literature on dissociation, trauma, and the use of art will be discussed. A case involving my work with an adolescent girl who had experienced sexual abuse from a family member will be shared, with an emphasis on the meaningful role images played during the therapeutic process. Both Jungian and psychoanalytic models of conceptualizing and working with dissociation are included, following Donald Kalsched’s (2013) recommendation for a “binocular stance” to treatment, including both a focus on the inner, intrapsychic world and the interpersonal, relational realm, and how art images both illuminated and expressed these realms. Within the therapeutic process, art images allowed the therapist a view into the client’s unconscious process, and created a meeting ground for dissociative barriers to be gradually seen, felt and known, by both therapist and client. The experience of dissociation, in images and in session, provided a reference point for myself and my client, Taylor, to develop a shared understanding and a framework for growth.
