摘要
对140名大学生进行了瑞文图形推理测试,然后从中选取了高分组和低分组各21名参加了脑波超慢涨落测试.结果表明:1)高分组和低分组在α波频率成分以及α波平均频率之间差异均不显著(P>0.05);2)推理能力无论是高分组还是低分组,前、后脑区平均功率符合额低枕高的前、后梯度.图形推理高分组在各个脑区的平均功率均高于低分组,在右额叶、右中央区、右前颞叶以及右后颞叶高分组和低分组差异显著(P<0.05);3)对图形的推理能力高分组和低分组S谱的9种基频成分在全脑出现次数的分析发现,在S 6成分上高分组和低分组差异显著(P<0.01),而在其他基频成分上高分组和低分组差异均不显著(P>0.05).
140 normal aged subjects are examined by Raven＇s Progressive Matrices task （CRT）, and then 21 high group students and 21 low group students are chosen to participate in the Encephalofluctuograph Technology （ET） test. The results obtained are as follows： 1） There is no significant difference in a wave frequency and the average frequency of a wave between the high group and low group（P〉0. 05）; 2） In both groups, the average frequency in the frontal and occipital area accords with low power in the frontal area and high power in the occipital area. The mean power of the high group students is higher than that of the low group students in every brain area, and there are significant differences in right frontal area, right central area, right anterior temporal area and right posterior temporal area between the high-ability and low-ability groups （P〈0.05）; 3） Through the analysis of times of appearance about the basic frequency components of 9 S spectrum between high group and low group, the detailed results are： it appears significantly less in high group than in low group in S 6 （P〈0.05） ; in other basic frequency components, the high group and low group dose not show significant difference （P〉0.05）.
