新颖语义联结在顿悟促进记忆效果中的作用

采用成语谜题选择任务, 通过学习-测验范式探究顿悟促进记忆的认知神经机制。实验1采用行为实验, 验证成语谜题选择范式在探究顿悟促进记忆中的有效性, 结果显示, 相比于寻常联结条件, 新颖联结条件下被试在学习阶段具有更高的顿悟感得分, 在测试阶段具有更高的正确率, 范式的有效性得以验证。实验2采用fMRI技术探究顿悟促进记忆的关键脑区。结果显示, 相比于失败记忆新颖联结条件, 成功记忆新颖联结条件更强地激活了顿悟过程相关脑区, 包括海马、杏仁核、额中回、颞上回和颞中回。这说明在学习阶段的顿悟问题解决过程中, 对信息的深加工与积极情绪促进了随后的记忆; 对其进一步分析发现, 相比于寻常联结记忆, 新颖联结对记忆的促进效应主要与右侧海马激活有关, 它可能反映了在顿悟问题解决中新颖联结形成过程建立了情节记忆以及新颖且有价值的语义联结。研究结果表明新颖语义联结形成在顿悟促进记忆中发挥了重要作用。     

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。     

Insights into sleep's role for insight: Studies with the number reduction task

In recent years, vibrant research has developed on “consolidation” during sleep: To what extent are newly experienced impressions reprocessed or even restructured during sleep? We used the number reduction task (NRT) to study if and how sleep does not only reiterate new experiences but may even lead to new insights. In the NRT, covert regularities may speed responses. This implicit acquisition of regularities may become explicitly conscious at some point, leading to a qualitative change in behavior which reflects this insight. By applying the NRT at two consecutive sessions separated by an interval, we investigated the role of sleep in this interval for attaining insight at the second session. In the first study, a night of sleep was shown to triple the number of participants attaining insight above the base rate of about 20%. In the second study, this hard core of 20% discoverers differed from other participants in their task-related EEG potentials from the very beginning already. In the third study, the additional role of sleep was specified as an effect of the deep-sleep phase of slow-wave sleep on participants who had implicitly acquired the covert regularity before sleep. It was in these participants that a specific increase of EEG during slow-wave sleep in the 10-12 Hz band was obtained. These results support the view that neuronal memory reprocessing during slow-wave sleep restructures task-related representations in the brain, and that such restructuring promotes the gain of explicit knowledge.     

Editorial to the special issue Neuronus

Did you visit the Neuronus conferences in the years 2012 and 2013 in Kraków? If not, then you certainly should have a close examination of this special issue including this introduction to at least have a glimpse of an idea of the highly interesting topics in the field of cognitive neuroscience that were presented at these conferences. If you were there, it is for sure a good choice to focus on this special issue as well, first to refresh your minds (we know our memories are far from perfect), but especially to see what happened with research of the presenters at these conferences.     

SPONTANEOUS “CURES”: NORMAN REIDER'S FORGOTTEN PAPER,PART II

Part I of this paper combined an introduction to Norman Reider's original 1955 paper with a republication of the paper itself. Part II is a discussion of the complexities of a comparison of past and present psychoanalytic literature. The concept of enactment is proposed as one of many possible alternative views in considering Reider's notion of spontaneous “cures.” A careful consideration of these spontaneous cures within the ordinary ups and downs of any psychoanalytic treatment sheds important light on our continuing confusion about how we define the term cure, and therefore about the nature of change during psychoanalytic treatment. This alternative perspective is only one of many plausible ones for present‐day readers. The purpose of this republication is not to propose an explanation for “what really happened” with Reider and his patients; rather, it is to reconsider the fallacy of evaluating his paper outside its historical context and thereby failing to appreciate his courage in presenting what at the time were radical views. Questions about the complexity and confusion regarding cure and change require reexamination of the neglect of epistemology on the part of psychoanalysis in prolonging the confusion about distinguishing psychotherapy and psychoanalysis.     

The good,the bad and the effective: a meta-analytic examination of selling orientation and customer orientation on sales performance

The concept of customer orientation (CO) is a focal construct in marketing and sales literature. Saxe and Weitz introduced CO to contrast the traditional high-pressure approach to sales (selling orientation). This study synthesizes empirical evidence from 1982 to 2013 to provide insight into the antecedents and consequences of both CO and selling orientation (SO). A conceptual meta-analytic model based on research into interpersonal motive models is proposed and tested using effect sizes from 126,790 salesperson survey responses to advance theory development on our understanding of how SO and CO behaviours affect organizations. Findings show that adaptive selling mediates the impact of both SO and CO which has important practical implications for hiring and training salespeople. Furthermore, this study shows that goal orientations are antecedents of SO and CO and that the impact of SO on job performance varies by customer type.     

自我损耗对科学发明问题解决中原型启发效应的影响

采用E-crossing任务和科学发明问题材料,探讨自我损耗对科学发明问题解决中原型启发效应的影响。结果发现：（1）自我损耗在原型激活率、关键启发信息激活率和问题解决正确率上的主效应显著,损耗组的原型激活率、关键启发信息激活率和问题解决正确率均低于控制组;（2）问题解决范式在原型激活率、关键启发信息激活率和问题解决正确率上的主效应显著,“一对一”范式下的原型激活率、关键启发信息激活率和问题解决正确率均高于“十对十”范式。结果表明,自我损耗导致的自我控制资源消耗不利于原型启发效应。     

Qualitative meta-analysis of insight events in psychotherapy

Purpose: This study reports on a qualitative meta-analysis examining the phenomenon of insight into psychotherapy. Method: Studies (n?=?7, covering 15 insight events of 15 clients) were selected that examined significant events in psychotherapy leading to insight using session recordings and Interpersonal Process Recall interviews with clients and therapists. A conceptual organization of the data using a matrix grid consisting of three domains according to data origin (client process, therapist process, and their interaction) and three domains according to events’ sequence (context, event and key intervention, and impact) was established. Results: Key processes were identified that lead to insight events in psychotherapy. Two distinct types of events according to their main impacts as reported by the clients were identified: Painful/Poignant Insight where clients realized something that was painful, often evoking feelings of sadness or undifferentiated upset containing sadness and hurt; and Self-Asserting/Empowering Insight that led to an impact characterized by a sense of self-assertion and empowerment on the client’s part. A reasonably good alliance and vulnerability on the client’s part represent the context for insight events as does the client’s quest for self-understanding. The therapists’ key interventions in the event leading to poignant/painful insight contain either empathic reflection or collaborative interpretation. In empowerment/self-assertive insight events the therapists offer supportive, validating reframing promoting positive experience. In both types of events the therapist and the client work on consolidating insight. In some events, therapists emphasized cognitive or problem solution focused impacts, while clients emphasized emotional impacts. Some events contained emotional avoidance on the part of the client or therapist thus not realizing the full potential of the event.     

Cognitive Insight in Inpatients with Psychotic, Bipolar, and Major Depressive Disorders

The Beck Cognitive Insight Scale (BCIS; Beck, Baruch, Balter, Steer, & Warman, 2004) was administered to 42 (28%) inpatients with psychotic disorders, 52 (35%) with a bipolar disorder, and 56 (37%) with a major depressive disorder (MDD). The hypotheses were (a) that the mean level of cognitive insight in a psychotic or a bipolar disorder is lower than that in a MDD, (b) that the mean levels of cognitive insight in psychotic and bipolar disorders were comparable, and (c) that the mean BCIS index score for a bipolar disorder in which the most recent episode had been mania is lower than the mean BCIS index score for a bipolar disorder in which the most recent episode had been mixed or depressed. All three hypotheses were supported. The results were discussed as supporting cognitive insight as a psychological construct that varies predictably according to the nature of a psychiatric disorder.
