Enhanced Recognition Memory after Incidental Encoding in Children with Developmental Dyslexia

Developmental dyslexia (DD) has previously been associated with a number of cognitive deficits. Little attention has been directed to cognitive functions that remain intact in the disorder, though the investigation and identification of such strengths might be useful for developing new, and improving current, therapeutical interventions. In this study, an old/new recognition memory paradigm was used to examine previously untested aspects of declarative memory in children with DD and typically developing control children. The DD group was not only not impaired at the task, but actually showed superior recognition memory, as compared to the control children. These findings complement previous reports of enhanced cognition in other domains (e. g., visuo-spatial processing) in DD. Possible underlying mechanisms for the observed DD advantage in declarative memory, and the possibility of compensation by this system for reading deficits in dyslexia, are discussed.Funding Agencies:Sven Jerring Foundation Foundation Sunnerdahls Disability Fund United States Department of Health & Human ServicesNational Institutes of Health (NIH) - USA R01 HD049347Mable H.
