【摘要】：本研究的目的是通过脑电技术考察文学特长生进行语言信息加工和非语言性质的空间信息加工时的脑功能模式。为此，本研究选择了18名在文学创作上具有突出成绩的语言文学专长的大学生（文学特长生）（平均年龄=20.94；标准差=1.06），并以随机方式选择了30名在文学上无特长的其他专业大学生作为普通对照组（平均年龄=20.55；标准差=1.68）。两组被试均接受瑞文高级推理测试（一项用于鉴别较高智力水平被试智力状况的非语言性质的智力测试）、语言阅读理解测试、二维空间旋转和三维空间旋转测试（测试空间能力中的心理旋转子能力）、镶嵌图形测试（测试空间能力中的空间知觉子能力）和皮亚杰水平测试（测试空间能力中的空间视觉子能力）。研究结果表明，文学特长生与普通大学生对照组在上述各项测试的行为指标（正确率）上无显著差异，但在语言信息加工和空间信息加工的脑激活模式上却存在显著差异。具体而言，在语言阅读理解加工时，与以往研究一致，普通被试表现出左脑主导的激活模式；所不同的是文学特长生表现出双脑激活模式，该模式可能表明文学特长生具有相对于普通被试更发达的右脑语言功能，即充分激活右脑资源协助语言加工的倾向，这个特征也可能是文学特长生依据的脑生理基础。在空间信息加工时，普通被试的脑激活模式与以往研究基本保持了一致，即以右脑主导激活模式来加工二维旋转测试，以左脑主导激活模式（左额叶和左颞叶）来加工三维旋转测试和镶嵌图形测试，以额叶主导激活模式来加工皮亚杰水平测试。与之相比，文学特长生表现出了语言加工脑功能模式迁移的趋势，在二维旋转、三维旋转和镶嵌图形测试上皆表现出双脑激活模式，，唯独在强调空间视觉信息快速判断能力的皮亚杰水平测试上表现出右脑主导激活模式，该结果反映不同空间子能力测试的性质差异调节了文学特长生表现出语言加工脑功能模式迁移的趋势，即文学特长生倾向于以其语言加工脑功能模式来加工较困难、可进行逐步分析的空间信息。上述文学特长生在语言信息和空间信息加工上表现出的独特的双脑激活模式可能是文学特长生这个群体的独特脑功能特征，该推论还需要进一步研究来证实。
[Abstract]:The purpose of this study is to investigate the brain function patterns of literary gifted students in the processing of language information and non-linguistic spatial information through EEG technology. To this end, this study selected 18 students with outstanding achievements in literary writing language and literature specialty (literary students) (mean age of 20.94; The standard deviation was 1.06, and 30 college students with no major in literature were randomly selected as the control group (mean age was 20.55; standard deviation was 1.68). Both groups were given the Raven Advanced reasoning Test (a non-verbal intelligence test used to identify the intelligence status of the subjects with a higher level of intelligence) and the language reading comprehension test. Two dimensional and three dimensional spatial rotation tests (to test mental rotation subcapabilities in spatial capabilities), mosaic graphics tests (to test spatial perceptual subabilities) and Piaget level tests (to test spatial capabilities) The spatial visual subability of the The results showed that there was no significant difference in the behavioral indexes (accuracy) between the literary gifted students and the normal college students, but there were significant differences in the brain activation patterns of language information processing and spatial information processing. In particular, in the processing of language reading comprehension, consistent with previous studies, the common subjects showed a left-brain-dominated activation pattern, while the literary gifted students showed a double-brain activation pattern. This model may indicate that literary gifted students have a more developed right brain language function than ordinary subjects, that is, the right brain resources are fully activated to assist language processing, and this feature may also be the basis of brain physiology for literary talents. In spatial information processing, the brain activation mode of the common subjects was basically consistent with previous studies, that is, the right-brain-dominated activation mode was used to process two-dimensional rotation test. The left brain-dominated activation mode (left frontal lobe and left temporal lobe) was used to process 3D rotation test and mosaic pattern test, and Piaget horizontal test was processed by frontal lobe dominant activation mode. In contrast, literary gifted students showed the tendency of brain function pattern migration in language processing, and showed two brain activation patterns in two dimensional rotation, three dimensional rotation and mosaic pattern testing. Only in the Piaget level test, which emphasizes the ability of quick judgment of spatial visual information, did the right-brain-dominated activation mode. The results show that the differences in the nature of different spatial subcompetence tests regulate the tendency of language processing brain function pattern transfer of literary gifted students, that is, literary gifted students tend to use their language processing brain function model to process more difficult. Spatial information that can be analyzed step by step. The unique biencephalon activation pattern in the processing of language information and spatial information may be the unique brain function of literary gifted students, which needs further study to prove.
