Teaching inner speech to help children with developmental language disorder

Training Verbal Mediation to Support Executive Function in Children With Developmental Language Disorder

NA · MGH Institute of Health Professions · NCT06880731

This project tests whether modeling self-directed 'inner speech' helps children with developmental language disorder improve their ability to switch between tasks and control behavior.

What this trial studies

The project enrolls 75 children aged 8 to 10 years divided into three matched groups: DLD-training (modeling verbal mediation), DLD-control (modeling only), and a typically developing control. The DLD-training group receives modeled verbal mediation intended to shape use of self-directed language, while controls receive modeling without the verbal mediation component. Outcome measures include behavioral metrics (accuracy and reaction time) and an electrophysiological EEG marker of cognitive shifting to capture real-time cue processing. Investigators will compare changes in use of verbal mediation and both behavioral and EEG measures of shifting to determine whether the training improves executive function in children with DLD.

Who should consider this trial

Good fit: Children aged 8;0–9;11 years with primary English, normal hearing on screening, TILLS Identification Core Score <34, KBIT-2 Fluid Subtest standard score ≥70, and no ADHD, autism, TBI, or other neurological disorders are the intended participants.

Not a fit: Children with co-occurring ADHD, autism, traumatic brain injury, significant hearing loss, non-English primary language, or KBIT-2 Fluid Subtest <70 are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the approach could give children with DLD better self-guided language strategies and improved cognitive flexibility that may help academic and everyday functioning.

How similar studies have performed: Language-based modeled interventions have shown promise in improving verbal mediation and executive function in typically developing children, but applying this approach to children with DLD is relatively untested.
