习得年龄效应被用来支持第一语言习得关键期的概念。在这项研究中，我们通过语法判断任务考察了聋人英国手语使用者的AOA效应。当英语阅读成绩和非言语智商被考虑在内时，结果表明，在8岁左右，语法判断的准确率随着AOA的增加而下降，这表明AOA对早期学习者的语法判断具有独特的影响。在那些在8岁后获得BSL的人中，没有发现这种影响。这些迟学的人似乎拥有第一语言熟练程度，这可能是在以后的生活中将BSL作为第二语言学习的基础。(C)2012爱思唯尔B.V.保留所有权利。
Age of acquisition (AoA) effects have been used to support the notion of a critical period for first language acquisition. In this study, we examine AoA effects in deaf British Sign Language (BSL) users via a grammaticality judgment task. When English reading performance and nonverbal IQ are factored out, results show that accuracy of grammaticality judgement decreases as AoA increases, until around age 8, thus showing the unique effect of AoA on grammatical judgement in early learners. No such effects were found in those who acquired BSL after age 8. These late learners appear to have first language proficiency in English instead, which may have been used to scaffold learning of BSL as a second language later in life. (C) 2012 Elsevier B.V.
