许多双语者从小就沉浸在以口语为主的环境中，与单语者不同，他们的语言使用不一定在不同的语言之间进行划分。尽管如此，与词汇水平相同的单语英语使用者相比，早期ASL-英语双语者在他们的主要语言字母流利性任务中提取的单词更少。这一发现表明，词汇量和/或使用频率的减少不能完全解释双语在言语流利性方面的劣势。取而代之的是，检索困难可能反映了语言之间的干扰。此外，它还表明，双语者的两种语言在选择上存在竞争，即使它们是用不同的发音方式表达的。
Many bimodal bilinguals are immersed in a spoken language-dominant environment from an early age and, unlike unimodal bilinguals, do not necessarily divide their language use between languages. Nonetheless, early ASL–English bilinguals retrieved fewer words in a letter fluency task in their dominant language compared to monolingual English speakers with equal vocabulary level. This finding demonstrates that reduced vocabulary size and/or frequency of use cannot completely account for bilingual disadvantages in verbal fluency. Instead, retrieval difficulties likely reflect between-language interference. Furthermore, it suggests that the two languages of bilinguals compete for selection even when they are expressed with distinct articulators.
