摘要
利用脑ET技术对认知功能正常的被试进行智力发展的脑电图研究。结果表明:(1)随着年龄的增长,小学生脑α波的平均频率呈明显的上升趋势,而中学生的变化幅度不大,但明显超过60年代的同期水平;(2)脑波平均频率的空间分布表现出额低枕高的前后梯度,在年龄低组被试有逆转现象,随年龄的增长,逆转现象减少,大脑的有序程度逐渐增强;(3)小学生的信息加工速度与脑α波的关系并不十分明显,而其脑波频率的分布和发展特点与计算速度有着根本的联系。中学生的表象能力与不同脑区平均频率的关系因年龄不同而有所差异,主要表现为在右顶叶、右前颞叶、右后颞叶和左后颞叶区域,表象能力好组频率大于差组。
The study on intelligence of normal students by ET showed that: (1)the average power of the brain alpha wave appeared higher with ages in primary school students, but it didn't do that in middle school students, and they were more higher than 1960s; (2)there were low power in the frontal area and high power in the occipital area in the configuration of dominant power encephalofluctuograph in younger group, and this phenomenon decreased with age getting older; (3)the relation between information speed and the brain alpha wave didn't appeared evidence. but the speed of calculation and the characteristics of brain wave power had certain underlying relation. It showed difference in terms of the relation between the imagery ability and the average powers of different brain areas with different ages, the power of the high group in right parietal area, right anterior temporal area, right posterior temporal area and left posterior temporal area was higher than those of low group.
