Canonical babbling of infants with and without Down syndrome was compared. Infants with Down syndrome and typically developing infants began canonical babbling in the first year of life, but the infants with Down syndrome began 2 months later. Once begun, their canonical babbling was less stable than that of typically developing infants. Age at onset of canonical babbling for the infants with Down syndrome was correlated with their scores at 27 months of age on the Early Social-Communication Scales. The results of this study suggest that Down syndrome influences vocal development in the first year of life and that early vocal development is related, possibly in combination with motoric and cognitive factors, to later social and communicative functioning of children with Down syndrome.
对患有和未患有唐氏综合征的婴儿的典型咿呀学语进行了比较。患有唐氏综合征的婴儿和发育正常的婴儿在出生后的第一年开始典型咿呀学语，但患有唐氏综合征的婴儿开始时间要晚两个月。一旦开始，他们的典型咿呀学语比发育正常的婴儿更不稳定。患有唐氏综合征的婴儿开始典型咿呀学语的年龄与他们在27个月大时在早期社会沟通量表上的得分相关。这项研究的结果表明，唐氏综合征会影响婴儿出生后第一年的语音发展，并且早期语音发展可能与运动和认知因素相结合，与唐氏综合征患儿后期的社会和沟通功能有关。
