认知灵活性和顿悟表征转换：练习类型的影响

以停车场问题为实验材料,以42名大学生为被试,探讨认知灵活性高和低的被试在不同练习类型下顿悟问题表征转换的差异。结果表明：1）不同的练习类型对顿悟表征转换有影响,被试在难度逐渐增加的练习类型下比在简单的练习类型下顿悟产生得更快;2）顿悟表征转换的速度因认知灵活性的不同有差异,在简单的练习类型下,认知灵活性高的被试比认知灵活性低的被试顿悟产生得更早,在难度逐渐增加的练习类型下两者无差异;3）认知灵活性高的被试比认知灵活性低的被试顿悟问题解决更快。     

竞争与情绪对顿悟的原型启发效应的影响

以汉字字谜为材料, 采用“原型学习-问题测试”范式, 考察不同竞争水平(高、中、低竞争强度和无竞争)情境下诱发的情绪效价(积极、中性和消极)对顿悟中的原型启发的影响。结果发现：1)竞争水平对字谜问题解决中的原型启发有显著影响, 低强度竞争水平最有利于靶字谜问题的解决, 中等强度和高强度下效果次之, 无竞争条件下效果最差; 2)诱发情绪对靶字谜问题解决的原型启发也有显著影响, 消极情绪和中性情绪下比积极情绪下靶字谜的正确率更高; 3)有无竞争与情绪效价之间的交互作用显著, 体现了竞争和情绪这两种动力相关因素在原型启发中的动力作用不是独立的。     

顿悟问题思维僵局早期觉察的脑电研究

思维僵局不仅是顿悟问题有别于常规问题的重要要素, 而且是顿悟赖以实现的基础。先前研究虽对顿悟瞬间的脑认知活动进行了较充分的探讨, 但却较少对思维僵局的有关过程进行研究。思维僵局究竟是源于早期的知觉阶段还是晚期的问题加工阶段至今仍是未解之谜, 但它却是人们认识顿悟过程所必需的。只有充分认识和理解了该过程, 才可能更全面地理解顿悟究竟建立在怎样的脑认知表征的基础之上。研究运用ERPs技术, 采用猜谜任务范式对顿悟中思维僵局产生的阶段及其脑认知活动进行了探讨。研究发现, 在120~210 ms和620~800 ms内, “有僵局”谜题较之“无僵局”谜题在额-中央区分别诱发了一个更正的P170和晚期LPC。其中, P170主要反映人脑对思维僵局的早期觉察, LPC则主要表征人脑经过一定解题尝试后对前期预评估僵局的修正和有意识反思。这些结果挑战了传统的思维僵局的晚期产生假说, 支持思维僵局的“早期产生机制”假说, 表明人脑在早期知觉阶段就能直觉地觉察思维僵局的存在。     

字谜问题解决中顿悟的原型启发机制再探

以中国传统字谜为实验材料,采用多对多的“学习-测试”二阶段实验范式和ERP记录手段,研究了原型字谜和靶字谜之间是否含有共同字词对顿悟的原型启发的影响。结果发现,在靶字谜呈现后的700ms内,正确解决有共同字词、无共同字词和基线条件字谜所诱发的脑电活动基本一致。在800-1700ms时间窗口内,有共同字词条件和无共同字词条件比基线条件诱发了一个更正的P800-1700成分,可能反映了原型启发下原型的激活和新颖联系的形成。此外,有共同字词条件和无共同字词条件诱发的波形始终趋于一致,可能表明字面上相同的字词并没有对原型启发产生影响,而原型字谜和靶字谜之间内在的语义联系才是原型启发的关键。     

Rethinking therapeutic action

Like other core psychoanalytic constructs, the theory of therapeutic action is currently in flux, as theorists of differing persuasions propose different mechanisms. In this article, the authors attempt to integrate developments within and without psychoanalysis to provide a working model of the multifaceted processes involved in producing change in psychoanalysis and psychoanalytic psychotherapy. A theory of therapeutic action must describe both what changes (the aims of treatment) and what strategies are likely to be useful in facilitating those changes (technique). The authors believe that single-mechanism theories of therapeutic action, no matter how complex, are unlikely to prove useful at this point because of the variety of targets of change and the variety of methods useful in effecting change in those targets (such as techniques aimed at altering different kinds of conscious and unconscious processes). Interventions that facilitate change may be classified into one of three categories: those that foster insight, those that make use of various mutative aspects of the treatment relationship and a variety of secondary strategies that can be of tremendous importance. They propose that, in all forms of psychoanalytic treatment, we would be more accurate to speak of the therapeutic actions , rather than action .     

The roles of the temporal lobe in creative insight: an integrated review

Recent studies have revealed that the temporal lobe, a cortical region thought to be in charge of episodic and semantic memory, is involved in creative insight. This work examines the contributions of discrete temporal regions to insight. Activity in the medial temporal regions is indicative of novelty recognition and detection, which is necessary for the formation of novel associations and the “Aha!” experience. The fusiform gyrus mainly affects the formation of gestalt-like representation and perspective taking. The anterior and posterior middle temporal gyri (MTG) are individually associated with extensive semantic processing and inhibiting salient or routine word associations, which are necessary to form non-salient, novel and remote associations. The anterior and posterior superior temporal gyri (STG) are individually responsible for integrating/binding and accessing various types of available conceptual representations. Based on the current knowledge, an integrated model of the temporal lobe's role in insight and some future directions are proposed.     

Metamemory knowledge and beliefs in patients with schizophrenia and how these relate to objective cognitive abilities

Subjective reports and theories about memory may have an influence on other beliefs and behaviours. Patients with schizophrenia suffer a wide range of deficits affecting their awareness of daily life, including memory. With the Metamemory Inventory in Adulthood (MIA) we ascertained patients’ memory knowledge and thoughts about their own cognitive capacities and about several aspects of cognitive functioning: personal capacities, knowledge of processes, use of strategies, perceived change with ageing, anxiety, motivation and mastery. The participants’ ratings were correlated with their intellectual, cognitive and psychiatric data. Patients felt they had a lower capacity and marginally lower mastery over their memory than comparison subjects. They reported less recourse to strategies, and higher levels of memory-related anxiety. However, their knowledge of basic memory processes, motivation to succeed, and perception of ageing effects were similar. So patients with schizophrenia do not suffer a general and non specific impairment of their metacognitive knowledge.     

三字字谜顿悟的时间进程和半球效应：一项ERP研究

运用事件相关电位ERPs技术, 采用猜谜任务范式, 从字谜问题解决中谜底“催化”所诱发顿悟的时间进程和半球差异两方面来探讨顿悟的认知神经机制。结果发现：在320~550ms内, “有顿悟”和“不理解”较“无顿悟”的ERP波形均有一个更大的负向偏移。在“有顿悟-无顿悟”和“不理解-无顿悟”差异波中, 该负成分的潜伏期约为380ms, 差异波的脑电峰值锁定在Cz点。半球主效应不显著, 但反应与半球交互效应显著, 其中“有顿悟”差异波的右半球平均波幅显著高于左半球和矢中部。结果表明：N380可能反映了顿悟中舍弃强外显意义而选择弱内在隐喻意义的认知抉择过程, 且右半球在“顿悟”中表现出优势效应。     

启发信息对个体顿悟问题解决影响的眼动研究

本研究以火柴棒算式问题为实验材料,采用2(问题类型:问题A、问题B)×2(启发类型:有、无)×2(认知风格:场独立型、场依存型)×5(兴趣区:第一个加数、加号、第二个加数、等号和结果)实验设计,考察顿悟问题解决时个体的眼动差异。结果发现:相对于场依存型个体,场独立型个体能够更有效地利用启发信息来减小表征变换时的心理加工负荷,进而提高加工效率;启发信息促进问题解决者对问题的表征从数值表征转变到符号表征,从而成功地产生了顿悟。     

How does mindfulness modulate daily stress response: evidences from ambulatory assessment

Objective: Mindfulness has been found to be associated with less adverse stress response. However, little is known about how mindfulness modulates stress response in the real daily life. The current study investigated the relation between daily stress and negative emotions, and explored a mediational link via perceived loss of control, and moderation by dispositional mindfulness, to better understand this association. Design: A total of 95 college students were recruited to complete a questionnaire and to report on their stress, perceived loss of control and negative emotions in daily life. Main Outcome Measures: Mindful Attention Awareness Scale (MAAS) was used to assess dispositional mindfulness. Stress, perceived loss of control and negative emotions were assessed by ambulatory assessment. Results: Stress was positively related with negative emotions at within-person level. Perceived loss of control mediated the relationship between stress and negative emotions. Furthermore, participants with higher levels of dispositional mindfulness showed an attenuated association between stress and anger, and also attenuated associations between perceived loss of control, and anger and fatigue at within-person level. Conclusion: These findings point to perceived loss of control as an important key factor in daily stress effects. Dispositional mindfulness appears to have beneficial effects in that it attenuates the impact of daily stressors on individuals’ wellbeing. Clinical implications and limitations are discussed.
