The Gerken lab has shown that infants are able to learn sound patterns that obligate local sequential dependencies that are no longer readily accessible to adults. The Goffman lab has shown that children with developmental language disorder (DLD) exhibit deficits in learning sequential dependencies that influence the acquisition of words and grammar, as well as other types of domain general sequences. Thus, DLD appears to be an impaired ability to detect and deploy sequential dependencies over multiple domains. We meld these two lines of research to propose a novel account in which sequential dependency learning is required for many phonological and morphosyntactic patterns in natural language and is also central to the language and domain general deficits that are attested in DLD. However, patterns that are not dependent on sequential dependencies but rather on networks of stored forms are learnable by children with DLD as well as by adults.
格肯实验室已经证明，婴儿能够学习那些存在局部顺序依赖关系的声音模式，而这些依赖关系对于成年人来说已不再容易获取。戈夫曼实验室已经证明，患有发育性语言障碍（DLD）的儿童在学习顺序依赖关系方面存在缺陷，这会影响单词和语法的习得，以及其他类型的领域通用序列。因此，DLD似乎是一种在多个领域中检测和运用顺序依赖关系的受损能力。我们将这两条研究路线结合起来，提出一种新的观点，即自然语言中的许多音系和形态句法模式都需要顺序依赖关系学习，并且这也是DLD中所证实的语言和领域通用缺陷的核心。然而，那些不依赖顺序依赖关系而是依赖存储形式网络的模式，DLD儿童和成年人都可以学习。
