The emergence of the Down syndrome (DS) behavioural phenotype during early development may be of great importance for early intervention. The main goal of this study was to investigate the good-imitator-poor-talker developmental profile in DS at preschool age. Twenty children with Down syndrome (DS; mean nonverbal mental age NMA 1 y10 m) and 15 children with non-specific mental retardation (NS-MR; mean NMA 1 y11 m) participated in this study. The Preschool Imitation and Praxis Scale (PIPS) and the Dutch version of the MacArthur-Bates Communicative Development Inventories (N-CDI) were used to determine absolute and relative (contrasted to a nonverbal mental age reference) imitation and language abilities. Results revealed that there was clear evidence for a good-imitator-poor-talker profile in preschoolers with DS. However, only the advanced bodily imitation ability seems to be syndrome-specific. Clinical implications of these findings are considered.
唐氏综合征（DS）行为表型在早期发育中的出现对于早期干预可能非常重要。本研究的主要目的是调查唐氏综合征（DS）儿童在学龄前的良好模仿者-言语表达障碍者的发展特征。20 名唐氏综合征（DS）儿童（平均非言语智力年龄 NMA 1 岁 10 个月）和 15 名非特定智力障碍（NS-MR）儿童（平均 NMA 1 岁 11 个月）参加了这项研究。使用学前模仿和动作能力量表（PIPS）和麦克阿瑟-贝茨交际发展量表（N-CDI）的荷兰语版来确定绝对和相对（与非言语智力年龄参考相比）模仿和语言能力。结果表明，DS 学龄前儿童有明显的良好模仿者-言语表达障碍者特征。然而，只有高级身体模仿能力似乎是综合征特异性的。考虑了这些发现的临床意义。
