Pilot Study of an Attention and Executive Function Cognitive Intervention in Children with Autism Spectrum Disorders

This pilot study investigated the efficacy of a game-based cognitive training program (Caribbean Quest; CQ) for improving attention and executive function (EF) in school-aged children with Autism Spectrum Disorder (ASD). CQ is a 'serious game' that uses a hybrid process-specific/compensatory approach to remediate attention and EF abilities through repetitive, hierarchically graded exercises delivered in an adaptive format. Game-play is accompanied by instruction in metacognitive strategies delivered by an adult trainer. Twenty children diagnosed with ASD (ages 6-12 years) completed 12 h of intervention in schools over 8-10 weeks that was facilitated by a trained Research Assistant. Pre-post testing indicated near transfer gains for visual working memory and selective attention and far transfer effects for math fluency. Exit interviews with parents and school staff indicated anecdotal gains in attention, EF, emotion-regulation, flexibility, communication, and social skills. Overall, this study provides preliminary support for the feasibility and potential efficacy of the CQ when delivered in schools to children with ASD.
