Caregiver-Infant tactile communication in infants at-risk for Autism Spectrum Disorder

Infant-directed multimodal communication facilitates attention in early development. This study examined the quantity and quality of caregiver touch and touch+speech input to 12-month-olds at high (HRA) and low risk (LRC) for ASD. Findings indicate that although both groups receive equal amounts of touch and touch+speech input (quantity), the percentage of touch+speech overlap within these events (quality) was significantly greater in the HRA group. Results show that mothers’ greater use of touch+speech is affected by infants’ responsiveness to specific types of input. Additionally, presentation of touch+speech input may facilitate orienting in HRA infants similar to LRC infants. Thus, presentation of multimodal input may be beneficial to HRA infants and mothers’ greater use of touch+speech events could be affected by infants’ responsiveness.
