摘　　要：本实验采用“找数字”的实验任务,对弱智儿童视觉搜寻目标定向运动速度进行研究,结果表明:(1)弱智儿童的搜寻时间显著大于正常儿童:(2)随着智残程度的加重,搜寻时间随之增长,但三类弱智儿童之间没有显著差异:(3)不论是弱智儿童还是正常儿童,附有图案的搜寻时间显著大于没有图案的,正常儿童尤其显著(P<.01)。作者对上述结果进行了分析,并结合其它相关研究,认为整个心理有缺陷、智力全面弱化是弱智儿童区别于盲人、聋哑人和肢体残疾人的一个重要特点。The present experiment used a“number—finding”task to study the characteristic ofmentally retardated (MR) children's visual target-searching speed.We took normalchildren as the control group,and found that:(1)it takes much longer time to finish thetask for MR subjects than for normal ones,(2) there is no remarkable difference of search-ing time among the three types of MR subjects (light、middle、heavy),(3) all of the sub-jects spend much longer time in the paper with patterns than in the paper without patterns.Moreover,the effect is especially notable among the normal subjects.The authors proposedthat mental retardation is the main feature of MR children.
