Caregivers typically use an exaggerated speech register known as infant-directed speech (IDS) in communication with infants. Infants prefer IDS over adult-directed speech (ADS) and IDS is functionally relevant in infant-directed communication. We examined interactions among maternal IDS quality, infants' preference for IDS over ADS, and the functional relevance of IDS at 6 and 13 months. While 6-month-olds showed a preference for IDS over ADS, 13-month-olds did not. Differences in gaze following behavior triggered by speech register (IDS vs. ADS) were found in both age groups. The degree of infants' preference for IDS (relative to ADS) was linked to the quality of maternal IDS infants were exposed to. No such relationship was found between gaze following behavior and maternal IDS quality and infants' IDS preference. The results speak to a dynamic interaction between infants' preference for different kinds of social signals and the social cues available to them.
照料者通常在与婴儿交流时使用一种夸张的言语模式，称为婴儿导向言语（IDS）。婴儿更喜欢 IDS 而不是成人导向言语（ADS），并且 IDS 在婴儿导向交流中具有功能相关性。我们研究了母亲 IDS 质量、婴儿对 IDS 相对于 ADS 的偏好以及 IDS 在 6 个月和 13 个月时的功能相关性之间的相互作用。虽然 6 个月大的婴儿表现出对 IDS 的偏好，但 13 个月大的婴儿则没有。在这两个年龄组中，都发现了言语模式（IDS 与 ADS）引发的注视跟随行为差异。婴儿对 IDS 的偏好程度（相对于 ADS）与婴儿接触到的母亲 IDS 质量有关。在注视跟随行为和母亲 IDS 质量以及婴儿 IDS 偏好之间没有发现这种关系。研究结果表明，婴儿对不同类型的社交信号的偏好与他们可获得的社交线索之间存在动态相互作用。
