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。     

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.     

Role of social value orientation in the endowment effect

The purpose of the present research was to explore the role of social value orientation in the endowment effect. The study gathered 190 participants from university students in Taiwan: 74 of these were classified as individualists, 44 as competitors and 56 as prosocials, with 16 being unclassified. Results from an experimental study indicated that the individualists' and competitors' average selling prices were significantly higher than the average buying prices for a commodity; thus the endowment effect was observed in these two orientations. The endowment effect was not observed in those having a prosocial orientation, however.     

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。     

心理咨询中领悟质量的评定依据——当事人和咨询师的视角

为获得当事人和咨询师对心理咨询中领悟质量的评定依据,采用协商一致的质性研究方法分别对13位当事人和15位咨询师的访谈材料进行分析。结果：当事人的评定依据包括影响力和特性;而咨询师的评定依据包括影响力、特性、类型、产生方式以及当事人对领悟的接纳程度。结论：领悟的影响力和领悟的特性是评定领悟质量的重要依据。     

工作记忆对顿悟和分析型问题解决的影响

摘要 采用顿悟-分析自我报告范式,以远距离联想任务为实验材料,从工作记忆容量和工作记忆负荷两个角度考察了工作记忆对顿悟和分析型问题解决的影响。结果表明,高工作记忆容量个体分析型问题解决的表现优于低工作记忆容量者,但在顿悟表现上无显著差异;工作记忆负荷较小时个体分析型问题解决表现更佳,但对顿悟表现没有影响。说明通过分析解决创造性问题的表现依赖于工作记忆的支持,而通过顿悟解决问题的表现与工作记忆无关。     

部件类型还是交错关系信息的习得促进问题解决？

本研究旨在探讨知觉组块中部件类型和空间交错关系信息的学习是否促进问题解决。研究采用学习-测试范式,71名有效被试（女性25名,平均年龄=20.51±2.35岁）先学习解答组块破解问题然后进行测试。研究分别在学习和测试阶段基于组块破解任务操纵了部件类型（汉字水平vs.笔画水平）和空间交错关系（交错vs.非交错）。学习阶段,被试分别在四组中完成组块破解练习;在测试阶段完成所有四组问题。研究发现,对交错关系信息的学习与利用相对于部件类型信息促进了问题解决：在涉及交错信息的测试任务上,涉及交错信息比非交错信息的学习条件解答率更高,反应时更短;反之则不是。然而部件类型则没有发现类似的促进效应。与此同时,交错关系信息的习得需要对任务的重复操作学习：涉及交错关系信息的组块破解学习成绩在不同任务间并不随时间推移而提高,但会随重复学习次数而提高。     

Insight solutions are correct more often than analytic solutions

How accurate are insights compared to analytical solutions? In four experiments, we investigated how participants' solving strategies influenced their solution accuracies across different types of problems, including one that was linguistic, one that was visual and two that were mixed visual-linguistic. In each experiment, participants' self-judged insight solutions were, on average, more accurate than their analytic ones. We hypothesised that insight solutions have superior accuracy because they emerge into consciousness in an all-or-nothing fashion when the unconscious solving process is complete, whereas analytic solutions can be guesses based on conscious, prematurely terminated, processing. This hypothesis is supported by the finding that participants' analytic solutions included relatively more incorrect responses (i.e., errors of commission) than timeouts (i.e., errors of omission) compared to their insight responses.
