'Your Baby Can't Hear You':How Mothers Talk to Infants with Simulated Hearing Loss

摘要

In this study mothers were told "your baby can't hear you," and their interactions recorded in either (i) a hearing condition in which infants could hear their mothers or (ii) a hearing loss condition in which infants could not hear their mothers. It was found that pitch levels of speech were similar in both conditions, but that there was vowel hyperarticulation in the hearing, but not the hearing loss condition, suggesting that mothers use of linguistic devices depends on their infants responsiveness.
