虽然大量的文献讨论了婴儿对婴儿导向言语（IDS）的偏好，但很少有研究探讨这种偏好如何随着时间或听力情况的变化而变化。这里报告的工作比较了婴儿在安静与嘈杂环境中听音乐时对IDS的偏好，并在发展的3个点：4.5个月大，9个月大和13个月大。几项研究表明，IDS可能有助于婴儿在噪音环境中挑选语音（科隆博，弗里克，Ryther，Collion，& Mitchell，1995; Fernald，1984;纽曼，2003）;这可能表明婴儿对IDS的偏好在这些环境中会增加。然而，事实并非如此;在所有3个年龄段，婴儿表现出类似的优势（或缺乏）IDS相比，成人导向的讲话时，在噪音与沉默。然而，有一个显着的年龄之间的相互作用：4.5个月的婴儿表现出整体偏好IDS，而年龄较大的婴儿没有，尽管听同样的刺激。年龄较大的婴儿缺乏影响，这重复并扩展了Hayashi，Tamekawa和Kiritani（2001）的最新发现，表明基频和情感的变化不足以提示年龄较大的婴儿的IDS。
Although a large literature discusses infants' preference for infant-directed speech (IDS), few studies have examined how this preference might change over time or across listening situations. The work reported here compares infants' preference for IDS while listening in a quiet versus a noisy environment, and across 3 points in development: 4.5 months of age, 9 months of age, and 13 months of age. Several studies have suggested that IDS might help infants to pick out speech in the context of noise (Colombo, Frick, Ryther, Coldren, & Mitchell, 1995; Fernald, 1984; Newman, 2003); this might suggest that infants' preference for IDS would increase in these settings. However, this was not found to be the case; at all 3 ages, infants showed similar advantage (or lack thereof) for IDS as compared to adult-directed speech when presented in noise versus silence. There was, however, a significant interaction across ages: Infants aged 4.5 months showed an overall preference for IDS, whereas older infants did not, despite listening to the same stimuli. The lack of an effect with older infants replicates and extends recent findings by Hayashi, Tamekawa, and Kiritani (2001), suggesting that the variations in fundamental frequency and affect are not sufficient cues to IDS for older infants.
