睡眠对儿童执行功能的影响

近期研究表明, 睡眠总量和睡眠质量都会对儿童执行功能的发展造成影响, 在自然睡眠条件下, 睡眠质量的影响倾向于即时性, 睡眠总量的影响具有滞后性, 在实验干预条件下, 少量的睡眠延长提高了儿童的执行功能表现。睡眠问题中研究最为广泛的睡眠呼吸障碍也会对儿童的执行功能带来危害, 但由于方法的不同, 目前的研究在结论上并不一致。随着年龄的增长, 睡眠对儿童执行功能的影响会逐步降低。此外, 基因、家庭社会经济地位等内外部因素也会对研究结果产生影响。未来的研究应针对执行功能中认知灵活性这一成分进行加强。     

睡眠剥夺影响恐惧情绪加工的认知神经机制

睡眠剥夺与恐惧情绪加工的各个过程息息相关。睡眠剥夺损害了恐惧的习得过程, 而且影响着杏仁核、内侧前额叶的活动及它们之间的功能连接; 睡眠剥夺削弱了恐惧记忆的巩固和再巩固过程, 不仅破坏了恐惧记忆再巩固过程相关蛋白质和酶的合成, 同时也影响着海马、杏仁核、内侧前额叶的活动以及它们之间的功能连接; 睡眠剥夺损害了恐惧的消退, 同时也改变了海马、杏仁核等相关脑区的活动模式。未来的研究应从睡眠剥夺影响恐惧情绪加工的认知神经机制、睡眠剥夺与恐惧情绪相关障碍的关系等角度展开, 力图深入理解睡眠剥夺影响恐惧情绪加工的认知神经机制。     

睡眠剥夺影响风险决策的双系统模型探讨

睡眠剥夺是指由于环境或自身原因无法满足正常睡眠时间的情况。大量实证研究发现, 睡眠剥夺会导致个体在风险决策中更倾向于风险寻求, 同时也有研究表明睡眠剥夺会导致个体风险规避, 而目前尚无统一结论。睡眠剥夺从风险感知、风险容忍、风险决策策略三个方面影响了风险决策, 其心理机制可由认知和情绪双路径模型进行解释, 且脑神经生理学研究也提供了相关证据。未来的研究应该进一步关注：(1)现实工作生活中的睡眠不足对风险决策的影响; (2)睡眠剥夺影响风险决策的理论模型建构。     

睡眠剥夺对风险决策的影响机制探讨

许多行业的决策者必须在睡眠不足的状态下做出选择与判断。睡眠剥夺是睡眠不足的实验室模型, 被证明能显著影响风险决策, 但内在机制不明。基于前人研究基础提出假设模型, 即睡眠剥夺通过影响个体的反馈加工、风险感知、抑制控制、决策理性, 进而影响风险决策。拟通过实验室研究与现场研究, 采用简单赌博任务、概率折扣任务、双选择Oddball任务等研究范式, 对比睡眠剥夺前后被试在执行上述实验任务时的行为差异, 同时比较执行控制网络、奖赏网络等脑功能网络连接强度, 以及任务诱发的FRN等脑电成分在睡眠剥夺前后的变化, 进而论证上述反应被试反馈加工等心理过程的行为-脑电-脑成像指标的变化与睡眠剥夺后被试风险决策变化的关系。研究结果将科学地解释睡眠剥夺影响风险决策的内在机制, 为进一步探讨如何规避睡眠不足导致的决策失误提供理论与实证依据。     

不同睡眠时间参数对学前儿童执行功能的差异化影响

研究选取78名5~7岁的学前儿童为研究对象, 采用睡眠日志法测量了儿童的夜间睡眠比、总睡眠时长和周末补偿睡眠三个睡眠时间的指标, 同时采用母亲报告法收集儿童的消极情绪性, 3个月后采用美国国立卫生研究院(NIH)的一套标准化测量程序评估儿童的执行功能, 探讨三个睡眠时间参数对不同消极情绪性学前儿童执行功能的差异化影响。结果发现, 在控制了儿童的同时性语言能力之后, 夜间睡眠比能够显著预测儿童三个月之后的执行功能; 儿童的消极情绪性与周末补偿睡眠对执行功能的三个子成分存在显著的交互作用。当周末补偿睡眠较少时, 高消极情绪性儿童的执行功能显著低于低消极情绪性儿童; 当周末补偿睡眠较多时, 高消极情绪性儿童的执行功能显著高于低消极情绪性儿童, 该结果符合差别易感性模型。     

睡眠对恐惧学习的影响及其认知神经机制

睡眠问题可能会诱发恐惧相关情绪障碍(焦虑、创伤性应激障碍、恐怖症等),研究睡眠影响恐惧学习的认知神经机制,有助于增强对恐惧相关情绪障碍的预测、诊断和治疗。以往研究表明睡眠剥夺影响恐惧习得和消退主要是通过抑制vmPFC活动,阻碍其与杏仁核的功能连接,从而导致恐惧习得增强或是消退学习受损。进一步研究发现睡眠不同阶段对恐惧学习相关脑区有独特的影响:剥夺(缺乏)快速眼动睡眠会抑制vmPFC活动、增强杏仁核、海马激活,导致恐惧习得增强,消退学习受损,此外边缘皮层的功能连接减少破坏了记忆巩固(恐惧记忆和消退记忆);而慢波睡眠主要与海马变化有关,慢波睡眠期间进行目标记忆重激活可促进恐惧消退学习。未来研究需要增加睡眠影响恐惧泛化的神经机制研究、及昼夜节律中断对恐惧消退的影响,以及关注动物睡眠研究向人类睡眠研究转化中存在的问题。     

贫困对个体执行功能的影响

已有研究发现,贫困会对个体的执行功能产生消极的影响,这种影响贯穿于个体婴儿期、童年期以及成年期。贫困会影响与执行功能相关的前额叶的结构（如较小的灰质体积）。贫困个体与非贫困个体对额叶区域资源的调用方式不同,贫困个体需要使用额外的补偿资源来监测和抑制对干扰物的反应。贫困会通过压力、认知剥夺以及父母养育等因素直接或间接的影响个体的执行功能。今后该领域的研究应关注贫困影响执行功能的调节变量（如自我肯定、自我调节）,建立贫困影响执行功能的综合模型（如考虑贫困经历时间等）,立足执行功能的可塑性,通过认知干预提高贫困个体的执行功能。     

不同时间睡眠剥夺对抑制能力影响研究

采用Stroop色词作业,考察不同时间(21h、45h、69h)睡眠剥夺(sleep deprivation,SD)后抑制功能情况。结果发现,无论字色一致还是不一致,SD后作业成绩下降;同一组中,除SD21组错误数外,字色不一致成绩显著低于字色一致;正常对照组中字色不一致条件下晚正波LPC平均波幅大于字色一致条件;SD后ERP差异波(字色不一致同字色一致相减波)时潜期延长,波幅降低,并在SD45h后显著。表明睡眠剥夺后抑制能力降低,并在45小时后显著。     

睡眠剥夺与购物后悔：来自大规模个体层面数据的证据

睡眠剥夺正在成为人们面临的一种普遍问题,但是已有研究很少将睡眠剥夺与消费者行为联系起来。本文采用真实购物情境下的大规模消费者个体层面数据(N=1625472),通过建立计量经济学模型来研究睡眠剥夺与购物后悔的关系。结果表明,睡眠剥夺显著地增加了消费者的购物后悔倾向,具体在行为上表现为增加了商品的退货概率和加快了商品的退货速度。此外,商品的价格正向调节了睡眠剥夺对购物后悔的影响,而促销优惠金额的比例则负向调节了睡眠剥夺对购物后悔的影响。     

小学高年级学生元认知监测对认知操作输出的影响:执行功能的调节作用

研究采用经典的执行功能测验-威斯康星卡片分类任务,通过自由报告法让被试对每次分类反应进行元认知监测、控制,以探讨小学五、六年级学生元认知控制、执行功能在元认知监测对认知操作输出（奖惩分数、正确应答比例提高指标）影响中的调节作用。研究结果发现：（1）执行功能指标中完成分类数、错误分类数、非持续性错误数、持续性错误数指标在元认知监测与正确应答比例提高之间的调节作用显著;（2）元认知监测在较低的执行功能水平上具有促进作用,即,当执行功能水平较低时,有效的元认知监测可以提高认知操作的输出成绩。研究结果支持元认知监控是与动机有关的、有意识的调节控制,为从理论上厘清元认知监控与执行功能的关系提供了实证支持。     

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.
