抑郁症患者工作记忆内情绪刺激加工的特点及其机制

抑郁症患者在工作记忆内情绪刺激加工的特点为倾向于加工与负性心境一致的材料, 被认为是抑郁症认知易感性的核心特征。目前研究者们围绕抑郁症工作记忆中央执行系统三个子功能的情绪刺激加工特点及其作用机制进行了大量研究, 发现在更新功能上, 患者难以移除负性情绪信息, 且在正性信息的加工上存在缺损; 在抑制功能上, 患者难以抑制无关负性情绪信息进入工作记忆; 在转换功能上, 患者情绪材料转换困难的研究证据尚不充分。神经生理与脑成像的研究初步表明, 工作记忆中的情绪刺激加工与抑郁症患者背外侧前额叶和前扣带回的功能激活水平异常有关。未来研究需评估工作记忆三个子功能对抑郁症状的差异性贡献及在情绪刺激加工上的统一性, 并探究其随疾病发生发展变化的轨迹, 谨慎选取并评估不同情绪刺激材料指标的诱发效应及其对工作记忆功能的独特影响。在此基础上, 深入探究工作记忆内情绪刺激加工的神经机制, 为工作记忆偏向矫正干预的临床应用及其预期效果提供理论依据和方向。     

An Exploration of Young Clients' Experiences in Counseling With Post‐Master's Counselors

This phenomenological study adds to current literature about clients' meaningful experiences in counseling by exploring the experiences of eight young clients (ages 8–18) in individual counseling with post‐master's counselors in an outpatient setting. Interviews with these clients revealed the following six themes: (a) the process of growth, (b) having a safe place to talk, (c) counselor accepts and meets the client where they are, (d) counseling is a team effort, (e) supportive accountability from the counselor, and (f) understanding self and others. The final theme includes two subthemes: learning coping and emotion management skills, and learning better ways to communicate and behave. Findings and implications for counselors are discussed.     

幸灾乐祸的重新审视和互动过程模型的构想

幸灾乐祸是人类普遍存在的一种社会情绪, 但却是一个远未研究透彻的领域。以往研究将幸灾乐祸视为一种不道德的情绪, 而现在越来越多的研究者认为其有一定的正向意义并循此展开研究。通过对国内外相关研究的全面梳理, 对幸灾乐祸的概念与测量方法的总结及对现有研究的整合, 构想了幸灾乐祸的互动过程模型。该模型的优势在于基于互动视角融合了互动双方(自身和他人)因素, 并基于过程视角明晰了幸灾乐祸乐祸发生的过程和发生后的变化。该模型指出今后研究者应关注幸灾乐祸前后事件的发生情境和情境中的多方互动, 并希冀对其他社会情绪研究具有一定启发意义。     

工作记忆中的积极效应：情绪效价与任务相关性的影响

积极效应指相比于年轻人, 老年人更倾向于优先加工积极情绪刺激而非消极情绪刺激。近年来工作记忆的研究发现积极效应会受到情绪效价与任务相关性的影响：情绪效价作为任务相关属性的研究支持工作记忆中存在积极效应, 具体表现为老年人对积极情绪刺激记忆的增强, 以及对消极情绪刺激记忆的减弱; 情绪效价作为工作记忆任务无关属性的研究相对较少, 且未发现一致的积极效应, 提示情绪效价及任务相关性均为影响工作记忆积极效应的关键因素。脑成像的研究初步表明, 工作记忆中情绪加工上的年龄效应与背侧执行系统和腹侧情绪系统的随龄功能变化有关。社会情绪选择理论与双竞争模型对工作记忆中的积极效应具备较大的解释力, 而动态整合理论尚缺乏实证研究支持。未来研究可进一步探究老年人工作记忆不同阶段情绪加工的特点, 澄清不同情绪材料内在编码过程上的差异对积极效应发生机制的潜在影响, 探讨情绪效价及任务相关性影响工作记忆积极效应的关键神经环路, 并揭示情绪工作记忆训练提升老年人认知功能与情绪体验的内在机制及其潜在应用价值。     

道德困境研究的范式沿革及其理论价值

通过评述道德困境研究范式的发展过程, 系统阐释了经典两难法、加工分离法、CNI模型法和CAN算法的优缺点和理论价值。后来的研究范式均在一定程度上克服了之前研究范式的局限。加工分离法克服了经典两难法的加工纯粹性假设等局限, CNI模型法在加工分离法基础上进一步分离了道德困境决策的多种心理过程, CAN算法则修正了CNI模型法的序列加工的不恰当预设。研究范式的沿革启示研究者综合应用新方法来解决研究争议和重新审视以往道德理论, 合理应用新方法来探索其他具有潜在冲突性的研究议题。总之, 本文为道德困境及相关研究提供了方法学参考。     

品牌消费旅程中消费者的认知心理过程——神经营销学视角

品牌消费旅程通常指的是对于品牌消费服务的多维度(包括认知, 情绪, 感觉, 行为和品牌关系)响应。揭示品牌消费旅程的认知心理过程是目前营销学领域之中研究的重点与热点。在梳理当前神经营销领域内有关功能性核磁共振(fMRI)、事件相关电位(ERP)、事件相关震荡(ERO)的相关研究成果后, 将消费者在品牌消费旅程之中的认知心理进程划分为注意吸引、决策形成、消费体验和品牌忠诚四个阶段, 并系统阐述了每个阶段之中消费者心理进程的神经机制与脑区活动, 进而全面立体地揭示消费心理的全貌。未来研究可以进一步探索不同神经指标在具体营销情境下的表征意义, 并结合超扫描技术进一步解析多个被试间的神经耦合情况。     

阈下情绪反馈对结果评价的影响及其性别差异

本研究用互动的决策游戏和脑电技术考察阈下情绪反馈对结果加工的影响。结果表明输钱相对于赢钱诱发更大的FRN/RewP和更小的P300,同时阈下愤怒反馈可以延缓赢钱之后下一次选择的反应时,并在女性被试中诱发更负的FRN/RewP, 但对反馈相关P300没有显著影响。这些结果说明阈下情绪反馈可影响决策结果评价早期的对刺激动机性意义的快速评估,但对晚期的深度评估没有显著影响,且这种影响在女性被试中更为明显。     

负性生活事件与儿童反应性攻击性之间的关系:一个有多重中介变量的结构方程模型

以977名9~14岁学生为对象,探索负性生活事件与儿童反应性攻击性之间的关系。研究使用了反应性与主动性攻击性问卷、Rosenberg自尊量表、青少年生活事件量表、艾森克人格问卷(儿童版)–情绪稳定性维度问卷,建立了以自尊和情绪稳定性作为中介变量,描述负性生活事件与反应性攻击性之间关系的结构方程模型。结果发现,负性生活事件可直接影响儿童反应性攻击性的形成,同时还可以通过改变情绪稳定性来影响反应性攻击性,即当负性生活事件发生时,情绪状态会倾向于不稳定,进而提高反应性攻击性的水平。此外,负性生活事件也会通过降低自尊水平来提高情绪状态的不稳定性,从而提高反应性攻击性的水平。     

Does private education make nicer people? The influence of school type on social–emotional development

In a longitudinal sample from Britain, we tested if attending private, fee-charging schools rather than non-selective state schools benefitted children’s social–emotional development. State (N = 2,413) and private school children (N = 269) showed no differences in well-being across adolescence, but private school children reported fewer behaviour problems and greater peer victimisation over time than state schoolers. These results were independent of schools’ selection criteria, including family background, and prior academic and cognitive performance. At age 21, private and state school students differed marginally in social–emotional behaviours, such as self-control, volunteering, sexual conduct, and substance use. After considering schools’ selection criteria, only risk taking and age at having the first alcoholic drink differed between private and state school children, with the privately educated ones being less risk averse and drinking at younger ages than those attending state school. Our results suggest that private education adds little positive value to children’s social–emotional development.     

PARENTAL CHILDHOOD ADVERSITY,DEPRESSIVE SYMPTOMS,AND PARENTING QUALITY: EFFECTS ON TODDLER SELF‐REGULATION IN CHILD WELFARE SERVICES INVOLVED FAMILIES

Parents who are involved with child welfare services (CWSI) often have a history of childhood adversity and depressive symptoms. Both affect parenting quality, which in turn influences child adaptive functioning. We tested a model of the relations between parental depression and child regulatory outcomes first proposed by K. Lyons‐Ruth, R. Wolfe, A. Lyubchik, and R. Steingard (2002). We hypothesized that both parental depression and parenting quality mediate the effects of parental early adversity on offspring regulatory outcomes. Participants were 123 CWSI parents and their toddlers assessed three times over a period of 6 months. At Time 1, parents reported on their childhood adversity and current depressive symptoms. At Time 2, parents’ sensitivity to their child's distress and nondistress cues was rated from a videotaped teaching task. At Time 3, observers rated children's emotional regulation, orientation/engagement, and secure base behavior. The results of a path model partly supported the hypotheses. Parent childhood adversity was associated with current depressive symptoms, which in turn related to parent sensitivity to child distress, but not nondistress. Sensitivity to distress also predicted secure base behavior. Depression directly predicted orientation/engagement, also predicted by sensitivity to nondistress. Sensitivity to distress predicted emotion regulation and orientation/engagement. Results are discussed in terms of intervention approaches for CWSI families.
