Early emergence of discrepancy in adaptive behavior and cognitive skills in toddlers with autism spectrum disorder.

ABSTRACT: Individuals with autism spectrum disorder and average IQ exhibit a widening discrepancy between lagging adaptive skills relative to their cognitive potential, but it is unknown when this discrepancy emerges in development. To address this important question, we measured adaptive and cognitive skills longitudinally, from 12-36 months, in 96 low-risk typically developing infants and 69 high-risk siblings of children with autism spectrum disorder who at 36 months were diagnosed with autism spectrum disorder (N = 21), the broader autism phenotype (N = 19), or showed no concerns (unaffected; N = 29). Results indicate that both cognitive and adaptive communication skills remained stable over time for all four groups, but toddlers with autism spectrum disorder and the broader
