内隐记忆研究综述

近年来,内隐记忆逐渐成为心理学研究的热点。本文概述了内隐记忆研究中两种主要的实验研究范式;任务分离范式和加工分离范式。同时,归纳与评价了四种主要的内隐记忆模型：阈限说、激活扩散理论、多重记忆系统理论和迁移恰当加工理论最后提出了四点内隐记忆研究对于教学的启发。     

网络成瘾者不同情绪状态下的认知加工特征

取在校大学生454人,通过《青少年病理性互联网使用量表》（Adolescent Pathological Internet Use Scale, APIUS),筛查出网络成瘾者31名为实验组,随机抽取样本中其他非成瘾大学生31人为对照组。使用词首－词尾对应三重意义组合图片60个为实验材料,用人物图片为情绪启动刺激,研究被试在不同情绪状态下的认知选择,记录被试选择词组性质和反应时间。研究发现,所有被试对积极词语的选择最多,对消极词语的选择最少,表现出“趋乐避苦”的认知选择倾向;成瘾组被试对积极词语的选择比对照组少,但是对消极词语选择比对照组多。悲伤启动情况下,成瘾组被试对积极词语的选择比对照组少,但是对消极词语的选择则比对照组多。成瘾组被试对积极信息的选择速度比对照组慢,但是对中性信息和消极信息的选择速度则比对照组快。愉快情绪启动下,成瘾组被试的反应时间比对照组短,在悲伤情绪启动下,成瘾组被试的反应时间比对照组长。悲伤情绪启动下,成瘾组被试对积极词语的反应时间比对照组慢,但是对消极词语的反应时间比对照组快。这些研究结果对网络成瘾的治疗有重要的参考价值。     

ALTERING RESPONSE CHAINS IN PATHOLOGICAL GAMBLERS USING A RESPONSE‐COST PROCEDURE

Two pathological gamblers could choose between emitting or having the dealer emit the response options when playing each of three casino games. A response‐cost procedure was introduced in a multiple baseline design across games in which the participant had to pay to perform the responses himself, which was somewhat effective at reducing many of the initial irrational choices made by each participant.     

ALTERING THE MAGNITUDE OF DELAY DISCOUNTING BY PATHOLOGICAL GAMBLERS

The present study explored the delay discounting of future and past monetary rewards by pathological gamblers. Using a multiple baseline design, following repeated exposure to choices between smaller immediate and larger delayed consequences, participants completed a relational responding task that attempted to alter the psychological functions of irrelevant stimuli and to affect subsequent delay discounting. Results support previous literature on the discounting of delayed consequences by pathological gamblers, illustrate that the discounting of past rewards occurs in a similar fashion to the well‐documented literature on the discounting of future rewards, and that magnitude of discounting can be altered.     

The body in the analytic session: focusing on the body-mind link

The author focuses on the importance of the body in the analysis of patients with a defect of thinking. In many cases this defect is not fully evident until concrete and bodily aspects begin to emerge in sessions. In the absence of awareness of the body, the patient's personality is deprived of the main source of emotional stimulus, and mental growth is consequently paralysed. Hence the body is considered the starting point of mental processes and a progressive source of experience requiring the exercise of responsibility and thought. To indicate the theoretical background to this essentially clinical paper, some hypotheses about the body-mind link are very briefly considered. Specific emphasis is given to the development of Freud-Klein-Bionian theories about this subject and to some of Ferrari 's recent proposals. The author discusses four clinical cases, emphasizing the encounter with the body in analysis and its integration in emotional and thinking processes. The analyst's function in such cases is conceived mainly as that of midwife for a dialogue between the analysand 's body and mind.     

On the determination of autistoid organizations in non-autistic adults

Psychogenic autistic phenomena occurring in non-autistic adults are being increasingly discussed in the psychoanalytical literature. The author endeavours to determine autistoid organizations, which are understood to be a particular form of pathological retreat. Together with the use of autistic objects, two-dimensional levelling out, the failure of unconscious communication, and of projective identification, a characteristic of these retreats is that they are meant to afford protection against paranoid-schizoid fears of the external and unintegrated states of the internal world. The formation of such autistic reactions should be sought not only in traumatic separations and the inadequate containment of primary objects, but also in constitutional weakening. Intolerance accompanying projective identification and damage to primal fantasies/preconceptions are discussed. In conclusion, a clinical illustration with autistoid and hypochondriacal retreats clarifies some of the aspects discussed.     

内隐操作绩效的加工分离:四分模型及其研究

一般认为,社会认知过程的内隐测量反映了不受个体控制的自动化加工.本文简要介绍了新近由Sherman等人提出的内隐操作绩效的四分模型及其相关研究.该模型认为,社会认知过程的内隐测量效应并非单纯自动加工的结果,而是多种加工成分的综合表达,这些成分包括联想的自动激活,确定正确反应的能力,对被自动激活联想的成功克服以及反应偏向的影响.该模型为重新认识内隐加工效应的机制提供了新的概念框架和分析技术,被广泛应用于基于内隐测量的社会认知研究领域,并引起该领域研究者的广泛关注.     

An experimental investigation of the automatic/voluntary dissociation in limb apraxia

The ability of apraxic patients to perform gestures in everyday life is a controversial issue. In this paper, we aimed to evaluate the automatic/voluntary dissociation (AVD) in four patients affected by clinically relevant limb apraxia. For this purpose, we sampled different kinds of gestures belonging to patients' motor repertoire and then assessed their production in a testing session. Our experimental procedure consisted of two steps: in the first phase, we recorded gestures produced by patients in two natural conditions; in the second phase, we assessed production of correctly produced tool-actions, and of spontaneous non tool-actions and meaningless conversational (cohesive and beats) gestures under different modalities. AVD was observed for all types of gestures, albeit to different degree in single patients. The present findings demonstrate that the context provides strong bottom-up cues for the retrieval of motor patterns, while artificial testing conditions impose an additional cognitive load.     

青少年病理性互联网使用量表的编制与验证

参照国内外研究并结合我国青少年的实际情况,旨在编制出更适合我国情况的青少年病理性互联网使用量表（Adolescent Pathological Internet Use Scale,APIUS）。探索性因素分析和验证性因素分析的结果表明APIUS由6个维度构成,即突显性、耐受性、强迫性上网/戒断症状、心境改变、社交抚慰、消极后果。APIUS显示了良好的信、效度指标,可以作为我国青少年病理性互联网使用的测量工具     

HOW PSYCHIATRIC TREATMENTS CAN ENHANCE PSYCHOLOGICAL DEFENSE MECHANISMS

Psychological defense mechanisms are a powerful and often unappreciated force safeguarding mental health. Although rarely directed in this way, the most common forms of psychiatric treatment—psychotherapy and antidepressants—can enhance psychological defense mechanisms. Psychotherapy, through both specific and nonspecific factors, induces positive perspective shifts favoring positive cognitive distortions, including adaptive classical defense mechanisms and healthy attribution biases. Antidepressants, by altering very basic emotional information processing, such as facial expression recognition and emotional memories, also foster positive cognitive distortions. By shifting perceptions and thoughts in a positive direction, psychotherapy and antidepressants improve the capacity to dissociate from negative emotional stimuli.Brad Bowins, M.D., FRCP(C), is a staff psychiatrist at the University of Toronto Health Service and he is in private practice.
