This study extended an existing crosslinguistic model of verb-marking errors in children's early multiword speech (MOSAIC) by adding a novel mechanism that defaults to the most frequent form of the verb where this accounts for a high proportion of forms in the input. Our simulations showed that the resulting model not only provides a better explanation of the data on typically developing children but also captures the crosslinguistic pattern of verb-marking error in children with developmental language disorder, including the tendency of English-speaking children to show higher rates of optional-infinitive errors and the tendency of Dutch-, German-, and Spanish-speaking children to show higher rates of agreement errors. The new version of MOSAIC thus provides a unified crosslinguistic model of the pattern of verb-marking errors in typically developing children and children with developmental language disorder.

MOSAIC+：典型发育儿童和患有发展性语言障碍儿童动词标记错误的跨语言模型

这项研究通过添加一种新颖的机制来扩展现有的儿童早期多词语音（MOSAIC）中动词标记错误的跨语言模型，该机制默认为最常见的动词形式，而该形式在输入中占据了很高的比例。我们的模拟表明，所得模型不仅可以更好地解释典型发育儿童的数据，而且还捕获了患有发展性语言障碍的儿童动词标记错误的跨语言模式，包括英语儿童表现出更高比率的倾向可选不定式错误的数量以及荷兰语、德语和西班牙语儿童的同意错误率较高的趋势。因此，新版本的 MOSAIC 为典型发育儿童和患有发育性语言障碍的儿童的动词标记错误模式提供了一个统一的跨语言模型。
