What this research studies

We know that early language skills are connected to the language infants hear around them, but most past work has focused on adults talking to babies. This project looks at the language infants hear from other children, which is a common experience for many. We want to understand if infants process speech from children differently than from adults, and if the content of child-produced speech impacts how babies learn to talk. Our goal is to discover why younger siblings sometimes develop language more slowly than first-born children.

Who could benefit from this research

Good fit: This project is interested in infants and young children, particularly those with older siblings, and their caregivers.

Not a fit: Patients not interested in early childhood language development or who do not have young children would likely not receive direct benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could help us better understand how to support language development in all children, especially those with siblings.

How similar studies have performed: While much research has focused on adult-infant speech, this project explores the relatively less-studied area of child-produced speech's influence on infant language development.
