蔡格尼克效应的存在说明人们对于那些未能完成的任务的记忆保持会更好,而利用单侧视野呈现技术对顿悟的研究也表明:人们在问题求解失败后,如提示信息出现较晚,则输入右脑的提示信息会比输入左脑的提示信息更能促成顿悟,提示右脑在未解决问题的保持以及对相关提示信息的处理中发挥重要作用.为了进一步验证上述结果,本研究利用汉字组块破解任务和事件相关诱发电位(ERP)技术,研究和比较了大脑左右两半球在问题求解失败以及关键提示信息呈现两个阶段的活动状况.结果发现,问题求解失败在右半球激发了更大的P150成分,而成功的问题解决却表现出相反的趋势;在提示信息呈现阶段对于P2成分波幅在问题类型(是否成功解决)和偏侧化的交互作用的分析表明,左半球不受问题类型的影响,而右半球的活动则是由不同的问题类型来调控的.上述结果验证了先前的推测,提示问题求解失败会引起右半球对相关问题信息的保持增强,并最终导致右半球对相关提示信息更加敏感.
The existence of the Chagrin effect indicates that people will be better able to maintain memory of those tasks that can not be completed. However, the research on epiphany using the unilateral visual field technology also shows that people who fail to solve problems, such as prompt information appearing later, The prompt information input into the right brain will contribute to the epiphany more than the prompt information input into the left brain, which implies that the right brain plays an important role in maintaining the unresolved problems and handling the related prompt information.In order to further verify the above results, Chinese block choking task and event-related evoked potential (ERP) technique were used to study and compare the activity of left and right hemispheres in the two stages of the failure of the problem solving and the key hint information presented in the two stages.It was found that failure of problem solving in the right hemisphere stimulated Larger P150 components, but successful problem solving showed the opposite trend; analysis of the interaction between the volatility of the P2 component and the type of problem (if resolved successfully) and the lateralization at the presentation stage of the message suggests that the left hemisphere is not affected Problem type, while the activity of the right hemisphere is regulated by different question types.The above results verify that Pre-speculation suggests that failure to solve a problem may cause the right-hemisphere to retain more relevant information and ultimately to the right hemisphere more sensitive to relevant prompts.
