Working memory and learning in children with developmental coordination disorder and specific language impairment

Area of Science:

• Developmental Psychology
• Neuroscience
• Educational Psychology

Background:

• Developmental Coordination Disorder (DCD) and Specific Language Impairment (SLI) are common neurodevelopmental disorders.
• Memory and learning are critical for academic achievement.
• Understanding the relationship between memory deficits and learning difficulties in these populations is crucial.

Purpose of the Study:

• To compare memory and learning profiles in children with DCD and SLI.
• To investigate the relationship between specific memory functions and academic attainment in these groups.
• To explore the underlying reasons for working memory's contribution to learning in DCD and SLI.

Main Methods:

• Comparison of 6- to 11-year-old children diagnosed with DCD and SLI.
• Assessment of verbal and visuospatial short-term and working memory.
• Evaluation of reading and mathematics attainment.
• Correlation analysis between memory measures and academic performance.

Main Results:

• Children with DCD exhibited impairments across all four tested memory domains (verbal/visuospatial, short-term/working memory).
• Children with SLI showed deficits specifically in verbal short-term and working memory tasks.
• Visuospatial working memory was strongly linked to numeracy in the SLI group.
• All memory measures correlated with at least one academic attainment measure in the DCD group.

Conclusions:

• DCD is associated with widespread memory deficits impacting learning, whereas SLI is characterized by more specific verbal memory impairments.
• The interplay between memory and academic skills differs between DCD and SLI, highlighting distinct cognitive profiles.
• Working memory plays a differential role in learning for children with DCD and SLI, warranting tailored interventions.
