语言是一种约定俗成的人类交流系统，说话者和签名者都在形式（单词或符号）和意义（概念）之间创建符号映射。通过社会化，儿童接触口语或手语，并通过学习形式和意义之间的映射来发展语言。尽管单词和符号的表达方式不同，但许多研究表明，母语手语者获得手语的发展模式与听力儿童获得口语非常相似。然而，由于手语是在视觉手势模式中产生的，因此在口语和手语的习得方面存在一些差异。Sign还利用了三维空间，年轻的签名者需要几年的时间来学习如何在空间中表达不同的观点。然而，尽管手语的视觉特性使得形式和意义之间的象似性程度更高，但这似乎并没有使手语的习得比口语的习得更快。与口语习得一样，由于语言发育迟缓，儿童可能会延迟学习手语。
Language is a conventionalized human communication system where both speakers and signers create symbolic mappings between form (words or signs) and meaning (concepts). Through socialization children are exposed to spoken or sign languages and develop language by learning mappings between form and meaning. Despite difference in the way in which words and signs are articulated, many studies have demonstrated that native signers acquire sign language following a very similar developmental pattern to hearing children acquiring spoken languages. However, as sign language is produced in the visuo‐gestural modality, there are some differences in how spoken and sign languages are acquired. Sign also makes use of three‐dimensional space and young signers take several years to learn how different viewpoints are represented in space. However, although the visual nature of sign language enables a greater degree of iconicity between form and meaning, this does not appear to make the acquisition of sign language more rapid than the acquisition of spoken language. As with spoken language acquisition, children can be delayed in learning to sign as a result of developmental language delay.
