Individual Differences in Executive Function Are Predictive of Autistic Children's School Readiness
Objectives: The present study investigated the relationship between emerging executive abilities and school readiness in pre-school children with and without autism. Further, we examined the extent to which individual differences in executive skills were associated with a child’s readiness for school in autism and typical development alike.
Methods: 30 preschool children on the autism spectrum (M age = 4.44 years; SD=1.02) and 30 typical children (M = 4.42 years; SD= .88), matched for age and ability, were assessed on a battery of tasks measuring components of EF, including set-shifting, working memory and inhibition, and school readiness (indexed by performance on the Bracken School Readiness Scale).
Results: Compared to typical children, autistic children performed significantly lower on the School Readiness Composite score, F(1,58) = 8.13, p =.006 and the School Readiness Social subtest, F(1,58) = 63.46, p < .001. Children on the autism spectrum also had more difficulty with set-shifting, F(1,58) = 34.26, p <.001, working memory, F(1,58) = 30.72, p < .001 and inhibition, F(1,58) = 13.20, p=.001. Additionally, and in line with our predictions, individual differences in autistic children’s EF skills, especially in spatial working memory, were related to variation in their school readiness, just like they were in typically developing children
Conclusions: The findings from this cross-sectional study provide further support for the potential role of EF in explaining the variability in autistic children’s functional outcomes, in this case, their readiness to learn at school. Intervention programmes to boost EF development in preschool children with autism – especially those that ‘exercise’ EF or rely on implicit rather than explicit instruction of such skills – should be a key priority for future research.
