The Department of Health and Human Services, through the National Institutes of Health (NIH), announces a funding opportunity (PAR-25-113) aimed at advancing research in children's language development. This initiative encourages the development of novel, culturally sensitive measurement tools for assessing language abilities, particularly for children from diverse backgrounds. The program aims to address the limitations of existing measures and to foster community-engaged research that includes input from affected communities. Funding of up to $275,000 for a two-year project period is available, with applications due beginning January 16, 2025. The grants support exploratory and developmental research through the R21 activity code. Applicants are required to submit a Community Engagement Plan and a Plan for Enhancing Diverse Perspectives (PEDP), which will be integral to the project’s evaluation. The primary objective is to shift the focus from merely quantifying language input in children to exploring a broader range of environmental influences and trajectories of language development. This funding opportunity aligns with the NIH TALK Initiative and emphasizes the importance of rigorous, inclusive, and culturally relevant research practices that aim to improve language outcomes for children at risk for delays.
