Influence of Naturalistic Language Intervention on Child Communication and Engagement

The purpose of this study is to parallel naturalistic instructional contexts that often occur during caregiver-child interactions (e.g., one-to-one arrangement during play) to learn more about how children respond when prompting is introduced compared to responsive interaction strategies alone or with environmental arrangement strategies. This exploratory study was designed to evaluate the potential differential effects within an ATD, comparing RI alone, RI + EA, and RI + MP on joint engagement, communication acts, and interfering behaviors. This study is ongoing and lacks results for communication acts. Preliminary results supported and contradicted aspects of the hypothesis: joint engagement would occur at relatively high sustained rates, and interfering behaviors would occur at low levels or none across all conditions (hypothesized outcomes for communication acts are omitted for the remainder of
