在这项研究中，我们研究了在一个错误发音检测任务中，各种来源的限制对口语单词识别的影响。5岁和8岁的儿童和成人提出的话（完整的或字初始或noninitial错误）从三个不同的年龄收购类别。“完整的”和“发音错误”的反应，收集孤立的话，或没有图片所指（实验1）和约束或非约束句（实验2）的话。一些证据表明，区别注意词的初始，而不是非初始的声学语音信息（因此，顺序词汇的限制识别的影响）是显而易见的，在幼儿和成人的反应标准，并在年龄较大的儿童和成人的反应时间。然而，一个更显着的发现是，根据几项指标，受试者的表现会随着年龄和词汇熟悉度（根据成年人的主观习得年龄估计定义）而变化。讨论了儿童在不同语境中对熟悉和不熟悉单词的反应策略。
In this study, we examined the influence of various sources of constraint on spoken word recognition in a mispronunciation-detection task. Five- and 8-year-olds and adults were presented with words (intact or with word-initial or noninitial errors) from three different age-of-acquisition categories. “Intact” and “mispronounced” responses were collected for isolated words with or without a picture referent (Experiment 1) and for words in constraining or unconstraining sentences (Experiment2). Some evidence for differential attention to word-initial as opposed to non-initial acoustic-phonetic information (and thus the influence of sequential lexical constraints on recognition) was apparent in young children’s and adults’ response criteria and in older children’s and adults’ reaction times. A more marked finding, however, was the variation in subjects’ performance, according to several measures, with age and lexical familiarity (defined according to adults’ subjective age-of-acquisition estimates). Children’s strategies for responding to familiar and unfamiliar words in different contexts are discussed.
