本文对正常儿童、严重弱智儿童和唐氏综合征儿童自发和模仿语音错误的数量和类型进行了比较研究。结果表明，正常组和严重低正常组的非唐氏综合征儿童的成绩相当，而唐氏综合征儿童的错误较多，且错误的不一致性较其他两组高。唐氏综合症儿童在模仿中的错误比他们在自发产生中的错误要少。这些发现被解释为一个迹象，即在严重低于正常的非唐氏综合症儿童中，语音发展与一般的心理发展有关。唐氏综合症组的特殊表现被假设为部分是由于在产生预定的运动序列方面的一般困难。
SummaryA comparative study of the number and type of phonological errors made spontaneously and in imitation by mental age matched normal, severely subnormal and Down's Syndrome children was carried out. The results indicated that the normal and severely subnormal non Down's Syndrome children performed equally, while the Down's Syndrome children made more errors, and those errors were more inconsistent as compared to the other two groups. The Down's Syndrome children made fewer errors in imitation than they did in spontaneous production.These findings were interpreted as an indication that phonological development is linked to general mental development in severely subnormal non Down's Syndrome children. The exceptional performance of the Down's Syndrome group was hypothesized to be partly due to a general difficulty in generating predetermined sequences of movements.
