Abstract
Background
School-age children rely on prospective memory (PM) to complete various tasks in the future. Previous research suggests children with autism spectrum disorders exhibit PM impairment, but whether PM impairment extends to children with higher autistic traits remains unclear. In the present study, we aimed to compare PM performance in children with higher and lower autistic traits and to examine potentially differential associations to executive functions.
Method
Forty pairs of children with higher and lower autistic traits between age 6- to 12-years old completed event-, time-, and activity-based PM tasks, and two executive function tasks (i.e., inhibition and working memory). We also collected parents-rated PM abilities using the Prospective and Retrospective Memory Questionnaire for Children.
Results
The two groups showed similar performance in both executive function tasks, the 3 PM tasks and parents-reported PM in daily life. In children with lower autistic traits, performance of the time-based PM task was correlated with working memory whereas it was correlated with inhibition function in children with higher autistic traits. Moreover, children with higher autistic traits exhibited a continuous reduction of time monitoring behavior across trials, leading to worse performance in the last PM trial compared with children with lower autistic traits.
Conclusion
Children with higher autistic traits showed intact executive functioning and similar PM performance as children with lower autistic traits, but they relied on different types of executive functions to complete time-based PM tasks. Moreover, children with higher autistic traits showed reduced time monitoring behavior and unstable PM performance across time.
期刊介绍：
Research in Autism Spectrum Disorders (RASD) publishes high quality empirical articles and reviews that contribute to a better understanding of Autism Spectrum Disorders (ASD) at all levels of description; genetic, neurobiological, cognitive, and behavioral. The primary focus of the journal is to bridge the gap between basic research at these levels, and the practical questions and difficulties that are faced by individuals with ASD and their families, as well as carers, educators and clinicians. In addition, the journal encourages submissions on topics that remain under-researched in the field. We know shamefully little about the causes and consequences of the significant language and general intellectual impairments that characterize half of all individuals with ASD. We know even less about the challenges that women with ASD face and less still about the needs of individuals with ASD as they grow older. Medical and psychological co-morbidities and the complications they bring with them for the diagnosis and treatment of ASD represents another area of relatively little research. At RASD we are committed to promoting high-quality and rigorous research on all of these issues, and we look forward to receiving many excellent submissions.
