Abstract

Late talkers are a heterogeneous group of children who experience delayed language development in the absence of other known causes. Late talkers show delays in expressive phonological development, but less is known about their receptive phonological development. In the current study, U.S. monolingual English-speaking typical talkers (TTs) (n = 23, mean age = 26.27 months, 57% male; 78.3% White) and late talkers (n = 22, mean age = 24.57 months, 59% male, 72.7% White) completed a Looking-While-Listening task to assess their sensitivity to mispronunciations. Results revealed that late talkers and TTs looked to the referent of a word for a shorter duration when it was mispronounced than when it was correctly pronounced, suggesting they were sensitive to mispronunciations. However, there were no significant differences between the two groups in their sensitivity to mispronunciations.

美国英语晚期说话者和典型说话者语音表征的特殊性
晚说话者是一群异质性的儿童,他们在没有其他已知原因的情况下经历了语言发展的延迟。晚说话者表现出表达性语音发展的延迟,但对他们的接受性语音发展却知之甚少。在本研究中,美国单语英语典型说话者(TTs) (n = 23,平均年龄= 26.27个月,57%为男性;78.3%白人)和晚说话者(n = 22,平均年龄= 24.57个月,59%男性,72.7%白人)完成了一项边听边看的任务,以评估他们对错误发音的敏感性。研究结果显示,说话晚的人和说话晚的人在一个单词发音错误时,会比正确发音时花更短的时间去寻找它的所指,这表明他们对错误发音很敏感。然而,两组人对错误发音的敏感度没有显著差异。
