手语的聋人用户，谁经常遇到的主要语言习得延迟的研究，允许一个独特的机会，以检查老化的影响下获得延迟或长期发展的主要语言（L1）的处理。107名年龄在45-85岁之间的先天性耳聋成年手语者，在婴儿期、幼儿期或幼儿期接触美国手语（ASL），使用ASL句子重复测试对其进行测试。参与者重复了20个句子，这些句子的长度和复杂性逐渐增加。以年龄和习得年龄为因素进行Logistic混合效应回归，评估句子重复准确性。结果表明，实足年龄是一个重要的预测因素，年龄增加与正确再现句子的可能性降低相关（OR = 0.56，p = 0.010）。此外，还观察到了习得年龄的影响。相对于本族聋人手语者，那些在儿童早期获得美国手语的人不太可能成功地再现一个句子（OR = 0.42，p = 0.003），而那些在儿童晚期学习美国手语的受试者（OR = 0.27，p <0.001）。这些数据表明，年龄的增长会影响ASL的聋人用户的逐字回忆，手语习得的年龄对重复能力有显着和持久的影响，即使在几十年的手语使用。这些数据显示了早期生命效应的寿命连续性的证据。
The study of deaf users of signed languages, who often experience delays in primary language acquisition, permits a unique opportunity to examine the effects of aging on the processing of a primary language (L1) acquired under delayed or protracted development. A cohort of 107 congenitally deaf adult signers aged 45–85 years, who were exposed to American Sign Language (ASL) either in infancy, in early childhood, or late childhood were tested using an ASL sentence repetition test. Participants repeated 20 sentences that gradually increased in length and complexity. Logistic mixed effects regression with the factors of Chronological Age and Age of Acquisition was used to assess sentence repetition accuracy. Results showed that Chronological Age was a significant predictor, with increased age being associated with decreased likelihood to reproduce a sentence correctly (OR = 0.56, p = .010). In addition, effects of Age of Acquisition were observed. Relative to native deaf signers, those who acquired ASL in early childhood were less likely to successfully reproduce a sentence (OR = 0.42, p = .003) as were subjects who learned ASL in late childhood (OR = 0.27, p < .001). These data show that aging affects verbatim recall in deaf users of ASL and that the age of sign language acquisition has a significant and lasting effect on repetition ability, even after decades of signed language use. These data show evidence for lifespan continuity of early life effects.
