摘要
研究者采用两种视觉检测时任务,比较了8至12岁超常和常态儿童的检测时发展变化特点。结果发现:随着年龄的增长,超常组和常态组儿童的检测时都呈现出逐步减小的趋势,并且对于不同任务的检测时,两组儿童的发展速度不同,但均未表现出性别差异;在不同的年龄段和不同的检测时任务中,超常组儿童的检测时均显著地快于常态组儿童。通过对两组儿童的检测时发展速率的比较还发现,儿童的检测时发展基本上不受学校知识或经验的影响。另外,两组儿童的检测时和智力测验分数之间都有中等程度的负相关。
Two typical visual inspection time tasks, line inspection time and digital inspection time, were employed in the present experiment. 172 children aged from 8- to 12-years-old (83 intellectual supernormal and 89 normal) were tested individually with the two IT tasks on computer. Meanwhile, in order to get their IQ scores, all subjects were asked to complete Cattell's cultur efair test. The schooling effect on speed of information processing was explored in the present study too. The results indicated that the inspection time of supernormal and normal children decreased gradually as their ages increased, but the developmental speeds or developmental curves were different on different inspection time tasks. There were no significant gender differences in the two tasks and three types of ages. Moreover, the inspection time of supernormal children was significantly faster than the normal children on the tasks in different ages. The correlation coefficients between inspection time and IQ scores in both supernormal and normal children were significant. And no schooling effects on children's speed of information processing (IT) were found. Comparing the developmental speed of the inspection time of the two samples, suggested that the knowledge and experience from schools have no effects on the development of children's inspection time. And the correlations between inspection time and IQ scores of both groups are significant.
