As they develop into mature speakers of their native language, infants must not only learn words but also the sounds that make up those words. To do so, they must strike a balance between accepting speaker-dependent variation (e.g., mood, voice, accent) but appropriately rejecting variation when it (potentially) changes a word's meaning (e.g., cat vs. hat). This meta-analysis focuses on studies investigating infants' ability to detect mispronunciations in familiar words, or mispronunciation sensitivity. Our goal was to evaluate the development of infants' phonological representations for familiar words as well as explore the role of experimental manipulations related to theoretical questions and of analysis choices. The results show that although infants are sensitive to mispronunciations, they still accept these altered forms as labels for target objects. Interestingly, this ability is not modulated by age or vocabulary size, suggesting that a mature understanding of native language phonology may be present in infants from an early age, possibly before the vocabulary explosion. These results support several theoretical assumptions made in the literature, such as sensitivity to mispronunciation size and position of the mispronunciation. We also shed light on the impact of data analysis choices that may lead to different conclusions regarding the development of infants' mispronunciation sensitivity. Our article concludes with recommendations for improved practice in testing infants' word and sentence processing online. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

婴儿对错误发音反应的发展：荟萃分析。

当婴儿成长为母语的成熟使用者时，他们不仅必须学习单词，还必须学习组成这些单词的声音。为此，他们必须在接受与说话者相关的变化（例如情绪、声音、口音）和当变化（可能）改变单词含义时适当地拒绝变化（例如猫与帽子）之间取得平衡。这项荟萃分析的重点是调查婴儿检测熟悉单词的错误发音或错误发音敏感性的能力。我们的目标是评估婴儿对熟悉单词的语音表征的发展，并探索与理论问题和分析选择相关的实验操作的作用。结果表明，尽管婴儿对错误发音很敏感，但他们仍然接受这些改变的形式作为目标物体的标签。有趣的是，这种能力不受年龄或词汇量大小的调节，这表明婴儿可能从很小的时候（可能在词汇量爆炸之前）就已经对母语音系有了成熟的理解。这些结果支持文献中提出的几个理论假设，例如对错误发音大小和错误发音位置的敏感性。我们还阐明了数据分析选择的影响，这些选择可能会导致关于婴儿发音错误敏感性发展的不同结论。我们的文章最后提出了改进在线测试婴儿单词和句子处理实践的建议。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
