The generalisation of linguistic constructions is performed through analogical reasoning. Children with developmental language disorders (DLD) are impaired in analogical reasoning and in generalisation. However, these processes are improved by an input involving variability and similarity. Here we investigated the performance of children with or without DLD in a construction generalisation task. We also compared their performance following training with an input involving progressive alignment (combining similarity and variability) or high variability. Progressive alignment improves construction generalisation in children with or without DLD, which could have implications for our understanding of language development and for interventions conducted with children with DLD.

有或没有发育性语言障碍的儿童语言结构的概括

语言结构的概括是通过类比推理进行的。患有发育性语言障碍 (DLD) 的儿童类比推理和概括能力受损。然而，这些过程通过涉及可变性和相似性的输入得到改进。在这里，我们调查了有或没有 DLD 的儿童在构建泛化任务中的表现。我们还将它们在训练后的表现与涉及渐进对齐（结合相似性和可变性）或高可变性的输入进行了比较。渐进式对齐改善了患有或未患有 DLD 的儿童的结构概括，这可能对我们对语言发展的理解以及对患有 DLD 的儿童进行的干预产生影响。
