Indirect effect of sensory seeking as measured later in the second year of life (i.e., 20–24 months) on future social symptom severity through social orienting in a community sample of infants at heightened, non-familial risk for autism spectrum disorder. a = the relation between sensory seeking and social orienting, not controlling for any other factors. b = the relation between social orienting and future social symptom severity, controlling for sensory seeking. c’ = the direct effect of sensory seeking on social symptom severity (i.e., the c’ path), controlling for social orienting. Values provided for a, b, and c’ paths are standardized coefficients. * p < 0.05. ** p < 0.01.
