Milieu Teaching-AV: Adaptation of Milieu Teaching That Encourages Looking to the Mouth

This project will look at Milieu Teaching (i.e., a language intervention) that encourages looking to audiovisual speech cues (Milieu Teaching-AV) for infants with autistic older siblings (Baby Sibs), who are highly likely be diagnosed with autism or developmental language disorder (DLD), compared to Milieu Teaching alone (Milieu Teaching-NoAV). This study will specifically look at whether Milieu Teaching-AV (compared to Milieu Teaching-NoAV) results in (a) increased looking towards caregivers' faces, (b) increased communicative behaviors and language skill, and (c) increased engagement with the caregiver during play. We will also look at caregiver factors, such as their use of strategies and their attitudes toward the intervention they received.
