Only a minority of profoundly deaf children read at age-level. We contend this reflects cognitive and linguistic impediments from lack of exposure to a natural language in early childhood, as well as the inherent difficulty of learning English only through the written modality. Yet some deaf children do acquire English via print. The current paper describes a theoretical model of how children could, in principle, acquire a language via reading and writing. The model describes stages of learning which represent successive, conceptual insights necessary for second/foreign language learning via print. Our model highlights the logical difficulties present when one cannot practice a language outside of reading/writing, such as the necessity of translating to a first language, the need for explicit instruction, and difficulty that many deaf children experience in understanding figurative language. Our model explains why learning to read is often a protracted process for deaf children and why many fail to make progress after some initial success. Because language acquisition is thought to require social interaction, with meaning cued by extralinguistic context, the ability of some deaf individuals to acquire language through print represents an overlooked human achievement worthy of greater attention by cognitive scientists.
只有少数深度失聪儿童的阅读水平能达到同龄人标准。我们认为,这反映出由于在幼儿期缺乏接触自然语言的机会而导致的认知和语言障碍,以及仅通过书面形式学习英语的固有困难。然而,一些失聪儿童确实通过阅读掌握了英语。本文描述了一个理论模型,说明儿童原则上如何通过阅读和写作来习得一门语言。该模型描述了学习阶段,这些阶段代表了通过书面形式进行第二语言/外语学习所需的连续的概念性见解。我们的模型强调了在无法通过阅读/写作之外的方式练习语言时所存在的逻辑困难,比如翻译成第一语言的必要性、明确指导的需求,以及许多失聪儿童在理解比喻性语言时所遇到的困难。我们的模型解释了为什么对失聪儿童来说,学习阅读往往是一个漫长的过程,以及为什么许多儿童在最初取得一些成功后就无法继续进步。由于语言习得被认为需要社会互动,且意义由语言外的语境提示,一些失聪个体通过阅读习得语言的能力代表了一项被忽视的人类成就,值得认知科学家给予更多关注。
