Study Summary
Thirty percent of children with autism barely talk or do not talk at all despite years of intervention. This study aims to address this important and long-standing challenge by developing a novel intervention to increase the quantity and quality of vocalizations (i.e., sounds children make before words) and expressive language in young children with autism (aged 2 to 5 years) with minimal verbal skills. The intervention includes contingent responses to the child's vocalizations and vocal elicitation strategies. We also collect social validity information from parents about how they perceive the novel intervention.
Primary Outcome
The investigators will calculate the proportion of children for whom the contingent responses with vocal elicitation strategies condition is successful based on the child producing more non-vegetative vocalizations in the contingent responses with vocal elicitation strategies condition than the non-contingent control condition.
