AI-Summary
What this Trial Is About
The 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; also known as specific language impairment). Other populations, such as at-risk toddlers, may also benefit from this new approach.
