Defense mechanisms predict differential lifespan change in Self-control and Self-acceptance

Individual differences in the direction of personality change over a period of 40 years for two scales of the California Psychological Inventory (CPI: Gough & Bradley, 1996) - Self-control (Sc) and Self-acceptance (Sa) - as previously identified through the use of longitudinal hierarchical linear modeling (Jones, Livson & Peskin, 2003), were studied in a sample of men and women from the Institute of Human Development Intergenerational Studies. It was hypothesized that the use of defense mechanisms, as assessed by the Defense Mechanism Manual (DMM: Cramer, 1991a), would be differentially related to change in Sc and Sa, depending on whether participants were increasing or decreasing in that trait over time. Results indicated that for participants who decreased in Sa, the use of Denial was associated with less decrease. For participants who increased in Sc, the use of Identification was associated with less increase.     

群体交叉分类效应的代数模型及其潜在加工过程

交叉分类被认为是一种能够有效减少群际偏见的方法。交叉分类效应的代数模型主要包括平均模型、相加模型和等价模型,各个模型都有自己成立的证据,其中支持相加模型的研究证据最多。尽管如此,交叉分类效应的代数模型有很明显的局限,即要求所有进行交叉的类别维度权重相等,这与真实社会情境是相矛盾的。交叉分类的潜在加工过程主要有基于认知角度的类别差异模型和基于动机角度的社会认同两种比较成熟的理论,前者又分为类别差异消除模型和类别差异减少模型。     

进化心理学取向与当代心理学

进化心理学以进化论为理论基础,用适应的观点来解释人类的心理机制及其行为方式。本文通过阐明进化心理学的产生背景,重点论述了进化心理学的思维方式及其与心理学主要学科分支的联系,并指出了进化心理学对当代心理学发展的影响。     

前瞻记忆的干扰效应：多重加工的证据

通过2个实验,对背景任务时间充裕和紧迫两种情况下的具体事件意向、类别事件意向、时间点意向、时间段意向四种前瞻记忆任务对背景任务的干扰效应进行考察。结果表明,在背景任务时间充裕情况下,类别事件意向对背景任务有干扰效应,具体事件意向、时间段意向和时间点意向都没有前瞻干扰效应;在背景任务时间紧迫情况下,时间点意向产生了干扰效应,具体事件意向、类别事件意向、时间段意向均无干扰效应。结果支持前瞻记忆的实现依赖多重加工的观点,时间性前瞻记忆并不一定比事件性前瞻记忆产生更大的干扰。     

Studying psychotherapy change in narrative terms: The innovative moments method

This paper aims to describe the Innovative Moments (IM) Coding System (IMCS), an idiographic and transtheoretical methodology that allows the identification of IMs—markers of changes in the client's initial maladaptive framework of meaning—throughout psychotherapy. The present study introduces the theoretical background underlying this methodology, along with the main empirical findings resulting from former studies that have applied this tool to clinical data. The IMCS application is also detailed: the coding phases, the training steps and inter‐rater agreement measures. In order to illustrate the application of IM coding, a case study is presented. Although a partial coding was used, the results are in line with previous research. Discussion is centred on the usefulness of the IMCS for the advance of process research in psychotherapy, and the potential use of this methodology in group format.     

公共政策情境中行为习惯的形成机制与培养策略

引导社会成员重塑日常良好行为习惯是增强公共政策有效性的重要路径和切入点, 洞悉并把握行为习惯的形成机制对具体培养策略的制定和实施大有裨益。行为习惯是指通过高频重复的奖励习得, 在记忆中形成的情境与反应之间的内隐联结。作为一种特殊的内隐记忆系统, 行为习惯具有自动化、情境线索依赖性、对当前奖励低敏感性等特征。行为习惯的形成机制包含两个独立且共发的习得机制, 即联结习得机制和奖励习得机制。在日常良好行为习惯的形成初期, 目标引导着个体对行为价值的习得。在培养社会成员日常良好行为习惯的过程中, 应将情境线索的稳定性、高频行为的低认知重复以及奖励的合理设置, 作为公共政策助推社会成员养成日常良好行为习惯的三大核心策略。未来的研究方向应着力于加强习惯研究的学科视阈融合, 更新行为习惯领域的研究范式, 重置公共设施以提升有益行为的易达性, 以及引入商业模式以共促社会成员日常良好行为习惯的重塑。     

我听故我在？自我声音识别机制的探索

自我声音是自我相关信息之一,同时也是个体识别身份时最重要的标志之一。声音具有骨传导和空气传导的传导方式和个体动机水平的差异都影响个体自我声音识别。在进行自我声音识别认知加工的过程中,会激活右半球额叶大部分脑区,并且在P3和N2成分上与在非我身份声音识别中同样存在显著差异。从声音刺激和个体动机两种角度来开展自我声音识别研究,并结合进化心理学与脑成像技术探索其神经机制,宜成为未来研究的一个方向。     

具身认知视角下语义理解中的身体角色:以研究方法为线索

具身认知认为,概念形成和语言理解等高级心理过程本质上是以感知觉和运动经验为基础的。神经影像学研究发现,理解身体动作词激活了支配该部分肢体的感觉运动脑区。理解手部、脚部和面部动作词能够相应激活支配手部、脚部和面部的感觉运动脑区,体现出一种身体动作词语义理解激活的脑区与真实身体动作激活脑区的耦合效应。临床和经颅磁刺激研究结果表明,感觉运动皮层的激活与身体动作词语义处理具有因果性作用。未来研究应关注身体动作词语义理解的具身程度以及相关语言疗法在临床患者机能恢复中所起的作用。     

Frontal Lobe Function and Pain in the Elderly

We review the literature on pain and aging and conclude that evidence supports a hypothesis that right frontal cortex contributes to the mediation of the chronic pain experience in elderly persons with chronic pain syndromes. Evidence for the right frontal pain hypothesis comes from clinical, neurocognitive, and neuroimaging studies, which implicate right inferior and orbitofrontal cortex in (1) the persistent pain experience, (2) negative emotional states, (3) retrieval of negative emotional and autobiographical memories, (4) regulation of autonomic arousal, and (5) regulation of attentional and pain functions of the anterior cingulate region. Right frontal dysfunction is also implicated in the effects of cognitive aging. If right frontal neurocognitive systems are affected in cognitively impaired elderly, and if (by hypothesis) the right frontal cortex also plays a major role in the experience of chronic pain, then cognitively impaired elderly with right frontal dysfunction should be protected to some extent from persistent pain syndromes. Available evidence supports this proposition.     

Amygdaloid function in the central cholinergic mediation of shock-induced aggression in the rat

A series of experiments was designed to examine the role of central cholinergic mechanisms in shock-induced aggression. Cholinergic blockade in the basolateral amygdala, ventral hippocampus, or dorsal hippocampus resulted in greatly reduced levels of fighting in response to footshock. However, while pain sensitivity remained unaltered in the amygdala group, both of the hippocampal groups exhibited decreased shock sensitivity. Further investigation of the amygdala revealed (1) increased fighting in response to increased cholinergic levels, (2) neuroanatomical specificity to the basolateral division of this complex, (3) that an intact basolateral amygdala is essential to the normal manifestation of shock-induced aggression, and (4) that social attraction remains unaltered by cholinergic blockade of the basolateral amygdala. Motor coordination and motor activity were not significantly affected in any treatment condition.
