This review addresses the question: How are signed languages learned by adult hearing learners? While there has been much research on second language learners of spoken languages, there has been far less work in signed languages. Comparing sign and spoken second language acquisition allows us to investigate whether learning patterns are general (across the visual and oral modalities) or specific (in only one of the modalities), and hence furthers our understanding of second‐language acquisition (SLA). The paper integrates current sign language learning research into the wider field of SLA by focussing on two areas: (1) Does ‘transfer’ occur between the spoken first language and signed second language and (2) What kind of learning patterns are the same across language modalities versus unique to each modality?

如何将手语作为第二语言学习？

这篇评论解决了一个问题：成人听力学习者如何学习手语？尽管对口语的第二语言学习者进行了很多研究，但在手语方面的工作却少得多。通过比较第二语言习得的手语和口语，我们可以研究学习模式是一般性的（跨视觉和口头形式）还是特定的（仅其中一种形式），因此加深了我们对第二语言习得（SLA）的理解。本文通过关注两个领域将当前的手语学习研究整合到SLA的更广泛领域中：（1）口语第一语言和手语第二语言之间是否发生“转移”，以及（2）跨哪种学习模式是相同的语言模态与每种模态的独特性？
