3H生物钟超日节律对图形命名测验一侧化效应的影响

Effect of Biological Ultradian Circa 3 Hour Rhythms on Cerebral Functional Laterality in Test of Naming Pictures

采用半视野速示技术对被试进行连续8h图形命名测验,检查生物钟超日节律对大脑两半球机能优势效应的可能影响.结果表明:①14例被试明显表现出周期约为3h的左右脑半球优势节律;②其中7例被试表现为连续左视野（右半球）优势波动,另7例为左右视野（两半球）交叉优势波动;③女性被试的节律周期明显长于男性被试,且男性被试倾向于出现持续右半球优势波动,而女性被试倾向于出现两脑小球交叉优势波动.

Tachistoscopic visual half-field test was used continously during 8 hour of daytime for 32 subjects to investigate the effect of biological ultradian rhythms on functional latendity for naming picture task. The results showed that: (1) there were distinct ultradian periodicties of about 3 hours observed for 14 subjects. (2) of whom 7 subjects appeared variations of the right hemisphereic dominance and the other 7 subjects appeared the cross-hemispheric dominance. (3) while the length of mean periods of women was significantly longer than that of men, men were inclined to appear sustained right hemispheric dominant variations and women appear cross- hemispheric dominant variations.
