摘要
顿悟的脑机制研究是当前创造性思维研究领域中的焦点和热点,关于语言的顿悟研究已积累了大量的实验数据;但仅有较少的研究探讨了图形顿悟脑机制的空间信息(相关的脑功能区),而有关图形顿悟脑机制的时间信息的研究至今未见报道。为此,本研究试图采用简单的几何图形为实验材料,并且使用事件相关电位技术(Event-Related Potentials,ERPs)进一步考察图形顿悟过程中脑内时程的变化。在实验过程中,实验首先呈现给被试几何图形要求被试进行组合想象或创造,之后呈现答案图形,以被试对答案图形的相应按键反应来区分顿悟和非顿悟两个条件。实验结果发现,顿悟条件比非顿悟条件诱发了N1成分,NI成分反映了对创造性图形答案形状的识别和判断过程,主要与视觉刺激的特征选择、评价有关,对该成分的觉察不但与顿悟过程中图形形态识别相关,而且还与顿悟与否的预期刺激的一致性相关。在300-450ms的时间窗内,顿悟条件比非顿悟条件诱发了一个更加负的脑电成分,虽然数据结果显示差异不显著,但是从差异波上我们还是看到了图形的偏移。且有顿悟差异波(即有顿悟条件与无顿悟条件ERP波相加减所得结果)在左右半球的激活程度存在显著差异,对于图形加工这种典型的右半球参与的认知活动,却发现大脑左半球的头皮的脑电电压值显著高于右半球和中部半球区。之后的550-700ms和700ms-1050ms晚成分波也发现了大脑的半球差异。左半球优势较右半球明显,这与传统的右半球负责图形加工的观点不尽一致。即可能关于图形顿悟的加工过程中涉及到对图形各部分之间空间关系表征,且这些空间关系是被类似语言的、符号表征存贮着,语义编码系统或者符号系统在对图形整合过程中扮演着重要的角色,而且这种表征主要在左半球表现得更好。
In the field of creative thinking, The brain research of insight always has been the focus and hot issue. we have accumulated a large amount of experimental data about language; But only less research discusses the brain mechanisms of visual insight's spatial information(brain regions), but the time information of visual insight's brain mechanism research has not yet reported. Therefore in this study, we use the simple geometric shapes as our experimental materials, and use event-related potentials technology(Event-Related Potentials, ERPs) to further investigate the neural basis of visual insight.In the experiment, the experimental materials were presented to subject and asked them to a combine、imagine or create, according to the button answers to distinguish the two conditions. The results found that insight conditions induced N1 component than non-insight conditions, N1 components reflect the recognition of creative graphic shapes and judgment process, the main characteristics of the visual stimuli selection, evaluation related to the composition and morphology of awareness not only to identify the relevant but also consistent with the expected stimulus related.Within 300-450 ms time window, the insighr conditions induced a more negative ERP components than non-insight conditions, although the data showed no significant difference, but we see the shift pattern from the difference wave. And there are differences wave(ie insight conditions subtract non-insight conditions obtained) significant differences in the degree of activation of the left and right hemispheres, visual processing, which typical participant in right hemisphere. we found that the left brain hemisphere scalp EEG voltage value is significantly higher than the right hemisphere and central dome area. Within 550-700 ms and 700ms-1050ms time window, the wave components were also different in the brain's hemispheres. This shows that in the machining process of visual insight the left hemisphere than the right hemisphere performs obvious advantages. This is not consistent with the traditional view of the right hemisphere is responsible for the graphics processing. Possiblely, in the processing of visual insight, graphics processing involves the spatial relationships between the various parts of the graphical representation, in the processing of images mainly characterize the spatial relationships between the various parts of the drawing, spatial relationship is storaged by the representation of language, symbolic represention, semantic coding system or the visual symbol system in the visual integration process plays an important role, and this characterization, mainly in the left hemisphere perform better.
