摘　　要：关于儿童认知发展的静息电位研究支持儿童发展的连续性与阶段性的统一,但诱发电位研究没能提供类似的证据,可能因为以往研究采用的oddball任务不够敏感。本研究通过改编形式运思任务来继续深入探讨儿童认知发展与大脑发育的关系。31名儿童(9岁组11人,10岁组10人,11岁组10人)完成形式运思任务,并同时记录脑电。结果发现:随着年龄增长,反应时逐渐缩短,正确率逐渐增高;三组儿童中,10岁组N380波幅最低,10岁组350-400毫秒的电位图较其他两组更为弥散。Evidence from resting EEG showed that cognition development is both continuous and discontinuous, while evokedpotential studies failed to prooide similar evideme, probably due to oddball tasks which were not sensitive enough. To investigate the electrophysiological evidence of cognitive development, an adapted formal-thinking task was employed. 31 children aged from 9 to 11 participated in the study and the electroencephalography as recorded. The results showed that reaction time decreased and accuracy increased with age. The N380 amplitude was lowest for the 10-year-old group, and the topography of 350-400 ms was more diffused for the 10-year-old group, which suggested a change of information processing mode or a transformation of brain maturation and cognitive development.
