Infants' early phonetic perception is hypothesized to play an important role in language development. Previous studies have not assessed this potential link in the first 2 years of life. In this study, speech discrimination was measured in 6-month-old infants using a conditioned head-turn task. At 13, 16, and 24 months of age, language development was assessed in these same children using the MacArthur Communicative Development Inventory. Results demonstrated significant correlations between speech perception at 6 months of age and later language (word understanding, word production, phrase understanding). The finding that speech perception performance at 6 months predicts language at 2 years supports the idea that phonetic perception may play an important role in language acquisition.
婴儿早期的语音感知被认为在语言发展中起着重要作用。以往的研究尚未评估生命最初两年中这种潜在联系。在本研究中，使用条件转头任务对6个月大的婴儿进行语音辨别测量。在13、16和24个月大时，使用麦克阿瑟沟通发展量表对这些儿童进行语言发展评估。结果表明，6个月大时的语音感知与后期语言（单词理解、单词生成、短语理解）之间存在显著相关性。6个月时的语音感知表现能够预测2岁时的语言能力，这一发现支持了语音感知可能在语言习得中起重要作用的观点。
