摘要:
 使用ERP技术对选取的27名右利手大学生（场独立14名，场依存13名）在图形一致性判断过程中的ERP进行分析，结果表明:1）在图形一致性的判断任务中，场依存者的前额叶与中央区在200 ms之前的N85与P160峰-峰之差明显大于场独立者，在枕叶区的负波N120波幅明显高于场独立者，这说明场依存者在对图形一致性比较的视觉信息处理的早期阶段即进行了更深度的加工。2）场独立者的N290波幅高于场依存者，而N290潜伏期比场依存者明显的长，这说明场独立者在后期对图形进行了更深入的分析比对。
Abstract:
 By using technology of ERPs，this research analyzed 27 right-handed undergraduates’ (14 field-independents and 13 field-dependents ) ERPs during the processing of the consistency judgment of graphics. The result indicates, (1)In a task on the consistency judgment of graphics, the difference of peak-to-peak between N85 and P160 in the frontal pole and the central area of the field-dependent individuals was more than that of the field-independent; and the amplitude of the N120 in the occipital area of the field-dependent was higher than that of the field-independent, which indicated that the field-dependent had made more profound processing at the early stage of the visual information processing in the task of comparison on the consistency of graphics. (2)The amplitude of N290 of the field-independent was higher than that of the field-dependent, and the latency of N290 of the field-independent was longer than that of the field-dependent, which implied that the field-independent made more profound comparison on the graphs during the later period.
