本研究采用定时语法判断任务，考察了美国手语（ASL）句子加工与母语习得年龄的关系。参与者是30名天生失聪的成年人，他们在出生到13岁之间首次接触到完全可感知的语言。刺激是六个美国手语句法结构的语法和不语法的例子：简单，否定，同意动词，疑问句，关系从句和量词句。由于延迟暴露于第一语言的增加，语法判断的准确性下降，独立的ASL句法结构。与语法刺激相比，第一语言学习者对非语法刺激的反应更慢，尤其是早期和延迟的第一语言学习者。研究结果适用于语法化的面部表情、符号标记和动词类型。这些结果，与以前的研究结果相结合，表明第一语言习得的开始影响句法知识的最终结果，为所有后续的语言习得。
Sentence processing in American Sign Language (ASL) was investigated as a function of age of first language acquisition with a timed grammatical judgement task. Participants were 30 adults who were born deaf and first exposed to a fully perceptible language between the ages of birth and 13 years. Stimuli were grammatical and ungrammatical examples of six ASL syntactic structures: simple, negative, agreement verb, wh-question, relative clause and classifier sentences. As delay in exposure to a first language increased, grammatical judgement accuracy decreased, independent of ASL syntactic structure. The signers were less accurate and responded more slowly to ungrammatical as compared with grammatical stimuli, especially the early and delayed first-language learners in comparison to the native learners. The results held across grammaticised facial expressions, signed markers and verb type. These results, in conjunction with previous findings, indicate that the onset of first language acquisition affects the ultimate outcome of syntactic knowledge for all subsequent language acquisition.
