Understanding how genes and environment affect infant social behavior and brain growth

Measuring gene-environment transactions to identify sensitive periods for infant social behavior & brain growth

NIH-funded research Emory University · NIH-10813690

This study is looking at how both genes and the environment shape how babies interact with people around them and how that affects their brain growth, using twins to help understand these influences better.

What this research studies

This research investigates how genetic and environmental factors influence the way infants engage with their social surroundings and how this affects their brain development. By studying identical and fraternal twins from birth, the project will use eye-tracking technology to observe infants' social visual engagement and MRI scans to assess changes in brain connectivity over time. The study aims to identify critical periods in early development when these gene-environment interactions are most impactful. Through standardized assessments, researchers will gather comprehensive data to better understand the developmental processes involved.

Who could benefit from this research

Good fit: Ideal candidates for participation are infants and toddlers, particularly those who are part of twin pairs, including both identical and fraternal twins.

Not a fit: Patients who are not twins or who are outside the infant and toddler age range may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding of early social development and interventions for children at risk for social behavior issues.

How similar studies have performed: Previous research has shown promising results in understanding the genetic influences on social behavior, making this approach both innovative and grounded in existing findings.
