A Framework For Linking Sequential Pattern Rules in DLD: Perception in Toddlers

Completed · Not applicable

Conditions studied: Developmental Language Disorder, Speech Sound Disorder, Specific Language Impairment

In brief

This broad aim of this clinical study is to assess the hypothesis that morphological and phonological deficits are linked by a broader deficit in sequential pattern learning. This hypothesis applies to learning in general, but is especially critical as an avenue for developing earlier assessments and more powerful interventions for children with developmental language disorder (DLD; AKA specific language impairment). Other populations, such as at-risk toddlers, may also benefit from this new approach.
