摘　　要：本研究探讨了均龄 1 0 .8岁的弱智儿童的视、触长度知觉辨别能力 ,并与均龄相同的正常儿童作了比较。结果表明 ,无论是弱智儿童或是正常儿童 ,对长度知觉的辨别 ,视觉的结果均明显优于触觉的结果。弱智儿童对长度知觉的辨别的准确性 ,无论是视觉或是触觉的结果均明显低于均龄相同的正常儿童。This study was investigating the ability of discrimination of length by sight and touch in mentally retarded children aged 9～12(average age 10.8).The IQ of the mentally retarded children from 39 to 59,the average IQ was 49.3.The results showed that the accuracy of discrimination of length by'Sight-Sight'condition was much better than under'Touch-Touch'condition.Comparing the results with the normal children aged 10～11(average age 10.4),it was found that the accuracy of discrimination of length by sight and touch was obvious lower than the normal children,it suggests that the IQ difference among the children made obvious influence to their perceptual discrimination.
