Children with Down's syndrome were compared with other severely retarded children on tests of recognition and reproduction of real and nonsense words after 0-, 15-, and 30-seconds delay. The results indicated that Down's syndrome children performed better on the recognition task, but worse on the reproduction task after delay, as compared with the other retarded children. It was hypothesized that the articulatory deficit in the Down's syndrome group is part of a general motor disability due to a difficulty in preprogramming sequences of movements.
在延迟0秒、15秒和30秒后，对唐氏综合征患儿与其他重度智障儿童进行了真实单词和无意义单词的识别与再现测试。结果表明，与其他智障儿童相比，唐氏综合征患儿在识别任务上表现较好，但在延迟后的再现任务上表现较差。据推测，唐氏综合征组的发音缺陷是由于运动序列预编程困难导致的一般运动障碍的一部分。
