摘要/Abstract

摘要： 本研究探讨了不同智商水平的弱智儿童的视觉图形辨认能力的差异,并与同龄正常儿童作了比较。结果表明,智商在31-51,平均智商为41.6,均龄为11.7岁的弱智儿童,在图形以0.05秒速度的呈现条件下,平均辨认正确率为21.4%;在以0.01秒速度呈现的条件下,平均正确率为20.7%。智商在55-75,平均智商为62.0,均龄为10.2岁的弱智儿童,图形以0.05秒速度呈现时,平均辨认正确率为48.5%;在以0.01秒速度呈现时,平均正确率为45.0%。与同均龄的正常儿童比较,无论在哪一种呈现速度条件下,对图形辨认正确率均明显低于正常儿童。

Abstract: This study was investigating the ability of visual figures in mentally retarded children aged 9-13(average age 11.2).The children were divided into two groups according to their intelligence quotient (IQ).Group A,IQ 55-75,average IQ 62.0;Group B,IQ 36-51,average IQ 41.6.Each group 14subjects.10figures were used as experiment samples.Each figure used as target was presented once by two kinds of exposed time(0.05 sec,0.01 sec).The subject was required to recognize the target figure from the 10 comparable figures.The results showed that the accuracy of recognition of visual figures for group B was obvious lower than for group A in both of the exposed time.Comparing the resolts with the normal children aged 10-11(average age 10.2),it was found,that the accuracy of recognition of visual figures was obvious lower than the nomal children.It suggests that the IQ difference among the children made obvious influence to their perceptual discrimination.

Key words: mentally retarded children, normal children, recognition of visual figures
