Differences in sensory seeking across the second year of life for high-risk infants according to diagnostic outcome. HR-No ASD = High-risk infants from a community sample who did not go on to receive a diagnosis of ASD (black line). HR-ASD = High-risk infants from a community sample who did go on to receive a diagnosis of ASD (gray line). Outcome group differences in sensory seeking were non-significant at Time 1 assessments, when infants were 13–15 months old, but significant by Time 2 assessments, when participants were 20–24 months old.
