We investigated whether adolescents and young adults with Down syndrome experience difficulty in finding words to name familiar objects. In Experiment 1, IQ- and MA-matched individuals with Down syndrome and with mental retardation due to other causes orally identified familiar pictures and sounds. Results showed no evidence of syndrome-specific word-finding difficulty in accuracy or speed. Although both groups identified auditory stimuli less accurately and more slowly than visual stimuli, results of Experiments 2 and 3 confirmed that young children without mental retardation and college students showed the same pattern. Although previous researchers have shown expressive speech deficits among people with Down syndrome, these results suggest that adolescents and young adults with Down syndrome show no syndrome-specific difficulty in finding words to label familiar nonverbal sounds or pictures.
我们研究了患有唐氏综合征的青少年和青年在为熟悉的物体寻找名称时是否存在困难。在实验1中，智商和心理年龄匹配的唐氏综合征患者以及因其他原因导致智力发育迟缓的个体通过口头方式识别熟悉的图片和声音。结果显示，在准确性或速度方面，没有证据表明存在特定综合征的找词困难。尽管两组识别听觉刺激的准确性都低于视觉刺激，且速度更慢，但实验2和实验3的结果证实，没有智力发育迟缓的幼儿和大学生也表现出相同的模式。尽管之前的研究表明唐氏综合征患者存在表达性言语缺陷，但这些结果表明，患有唐氏综合征的青少年和青年在为熟悉的非语言声音或图片寻找标签时，没有表现出特定综合征的困难。
