Sohyun An Kim; Connie Kasari – Journal of Autism and Developmental Disorders, 2025
While working memory (WM) is a powerful predictor for children's school outcomes, autistic children are more likely to experience delays. This study compared autistic children and their neurotypical peers' WM development over their elementary school years, including relative growth and period of plasticity. Using a nationally-representative…
