THE DEVELOPMENT OF ENCEPHALOFLUCTION AND ITS RELATIONS WITH SPEED OF INFORMATION PROCESSING FOR PUPILS OF 6 TO 12

Wo Jianzhong Lin Chongde Cao Heyin Hu Qingfen (Institute of Development Psychology, Beijing Normal University, 100875, Beijing, China)  
Two hundred and one 6~12 year old pupils encephalofluction is recorded and analyzed in detail by encephalofluctuography technology (ET). The tendency of changes in encephalofluction with age and its relations with speed of information processing are discussed. The results are as follows: (1) In the process of development from 6 to 12, the tendency of changes in power of different S spectral lines is different. In all S spectral lines, power of 6 years is stronger than other ages generally. And in several S spectral lines such as S1, S2, S4 and S5, these differences are significant. (2) The tendency of changes in S spectral power for boys and girls is different. Power peaks of girls S spectral lines usually appear in 6 or 7 years. S spectral power of 9 years is the weakest for girls. As a contrast, power peaks of boy S spectral lines almost appear in 9. (3) Children who do well in different information processing tasks appear different trails of relations between S spectral power in anterior brain and that in posterior brain. Children whose S spectral power gets dominance in anterior brain do well in the task of letter matching. And children whose S spectral power gets dominance in posterior brain do well in the task of mental rotation. (4) Children who do well in different information processing tasks appear different trails of relations between S spectral power in left brain and right brain. Children whose S spectral power appears balance between left brain and right brain do well in the tasks of simple reaction, select reaction and figure matching. And children whose S spectral power in left brain and in right brain is imbalance do well in the task of sentence picture matching.
