四字谜问题解决中原型启发的时间抵消与位置效应

根据顿悟的原型启发理论,通过两个实验考察原型启发的时间抵消和位置效应。实验1采用2（字谜类型）×2（原型呈现时间）混合设计,结果发现：松组块字谜的正确率显著高于紧组块字谜;原型谜面消失的正确率显著大于谜面存在的正确率。实验2采用2（原型位置）×2（字谜类型）×2（原型呈现时间）混合设计,结果不仅证明了实验1,且原型位置、字谜类型、原型呈现时间的交互作用显著,原型在靶字谜之前时,紧组块字谜上谜面消失的正确率显著大于谜面存在的正确率;原型在靶字谜之后时,松组块字谜上谜面消失的正确率显著大于谜面存在的正确率。表明字谜顿悟问题解决中存在原型的时间抵消和位置效应,二者连同任务难度共同影响问题解决。     

情绪影响创造性认知过程的神经机制

先前有关情绪与创造力的研究多以行为实验为主, 且存在研究结果不一致、缺乏可比性等问题。本项目拟借助认知神经科学技术, 以认知加工的初级过程和次级过程为线索, 采用新颖性判断、远距离联想、顿悟字谜任务等改进的实验范式, 通过时空二维脑机制参数, 重点测查创造力相关脑区激活的时间进程与空间模式, 揭示情绪影响创造性认知活动的大脑动态加工过程。     

执行功能对言语顿悟问题解决的影响:基于行为与ERPs的研究

执行功能是否影响顿悟问题解决,顿悟问题解决中的表征重组阶段是否涉及执行功能仍存在争议。基于此,通过2个研究探讨执行功能对顿悟问题解决的影响。研究1初步探讨执行功能与个体顿悟能力之间的关系,结果发现个体的执行功能与其顿悟问题解决成绩之间存在显著正相关,刷新功能可以显著预测顿悟成绩;研究2使用汉字字谜任务,通过行为与ERPs技术探讨执行功能对言语顿悟问题解决的影响,其中研究2a,行为实验发现高工作记忆刷新能力的个体反应时显著小于低工作记忆刷新能力的个体,说明执行功能中工作记忆刷新亚成分影响顿悟问题解决。研究2b脑电结果发现,"顿悟"条件较之"无顿悟"条件诱发了一个更强的早期成分P2和N2,以及中晚期P3。P2可能主要反映人脑对思维僵局的早期觉察,受到执行功能高低的影响。280~500 ms内,中晚期P3则主要体现以新旧思路交替为特征的僵局打破过程,不受执行功能高低的影响,结果表明汉字字谜顿悟问题的表征重组阶段并未受到执行功能的影响,更倾向认为该阶段为一个突进的过程。综合2个研究说明,执行功能影响顿悟问题解决,其主要作用于顿悟问题解决过程的问题空间搜索阶段,而表征重组阶段是一个突进式的过程。     

MAX EITINGON'S RISE AND DECLINE: THE BERLIN YEARS

Max Eitingon's main achievement was the foundation of the Berlin psychoanalytic Poliklinik that served both as an outpatient center and a training institute. Another area of his responsibility was the Verlag, the International Psychoanalytic Press. By 1926, he occupied several leading positions, including presidency of the International Psychoanalytical Association and editorship of the major psychoanalytic journal of the time. The basis of his power was his personal relationship with Freud, as well as his monetary wealth, which he put into the service of the Freudian cause. By 1932, he had suffered an overall setback, however, with the Berlin Institute losing its best teachers, the Verlag barely escaping bankruptcy, and the journal's editorship returning to Vienna.     

顿悟体验的心理与神经机制

顿悟体验研究是揭示顿悟本质的重要途径。先前研究从认知角度对顿悟问题解决中的"旧而无效解题思路如何抛弃"与"新而有效解题思路如何形成"过程进行了颇多探讨,但较少探讨顿悟体验本身。顿悟体验研究对理清创造性顿悟中关键过程间的关系及阐明顿悟的科学规律均有重要的意义。基于创造性顿悟的"新旧交替"的动态视角,本项目拟借助多元方法来对言语类和视图类问题解决过程中尝试解题阶段和答案闪现阶段的顿悟体验的心理实质与脑机制进行研究。本项目成果不仅可以丰富和优化顿悟问题研究的方法学体系,而且能从知情转化层面深化对创造性顿悟脑机制的认识。     

Crossing the invisible line: De-differentiation of wake,sleep and dreaming may engender both creative insight and psychopathology

Writing about dreaming, the poet Raymond Carver said “I feel as if I’ve crossed some kind of invisible line”. In creative people, the “line” between wake, dreaming and psychopathology may be porous, engendering a de-differentiated, super-critical, hybrid state. Evidence exists for a relationship between creativity and psychopathology but its nature has been elusive. De-differentiation between wake, sleep and dreaming may be the common substrate, as dream-like cognition pervades wake and wake-like neurophysiology suffuses sleep. Chaos theory posits brain states as inherently labile, transient and dynamically unstable. Over and above transient dissociations, an enduring and, sometimes, progressive, de-differentiation may be possible. Evidence indicates that sleep and dreaming facilitate creative insight. In consequence, a mild to moderate form of de-differentiation may enhance creativity but if wake-like neurobiology permeates sleep this may disrupt sleep-dependent memory processing and emotional regulation. If de-differentiation is progressive and enduring, various forms of psychopathology may result.     

From Walls to Windows: Using Barriers as Pathways to Insightful Solutions

The purpose of this study was to explore and develop a conceptual model for how individuals unlock insight. The concept of insight — the ‘out of the box’ or ‘aha!’ solution to a problem — offers a framework for exploring and understanding how best to enhance problem solving skills due to the cognitive shift insight requires. Creative problem solving (CPS) is inherent to a variety of performance realms including effective decision making, innovation, and organizational development; however, related processes of insight, innovation and creativity remain intangible. The model, based on a review of the problem solving literature, proposes that insight involves a five stage, cyclical process emerging as: primary appraisal of the problem, secondary appraisal based on prior knowledge, initial focus, problem representation, and solution generation when, if no solution is found, the cycle begins again. The research has implications for individual, team and organizational settings suggesting that performance on a wide variety of problems may be improved by utilizing an integrated focus rather than a barrier or goal focus alone.     

超越人生的困境——论苏东坡对佛学如是观的认识

苏东坡对佛学人生观的领悟概括地讲即是对佛学“如是观”的认识。所谓“如是观”,在佛学中的本义被认为是以一种非世俗的般若佛智来观照世法真实相状的正确看法。因此,苏东坡虽经历诸多人生痛苦,却能以超然的态度作“如是观”,这也可以说是般若空观在东坡生活道路上所起的积极作用。
