"Science Briefs" summarize the findings and implications of a recent study in basic science or clinical research. This brief reports on the study "Mother-Child Bookreading in Low-Income Families: Correlates and Outcomes during the First Three Years of Life" (H. Raikes, B. A. Pan, G. Luze, C. S. Tamis-LeMonda, J. Brooks-Gunn, J. Constantine, L. B. Tarullo, H. A. Raikes, and E. T. Rodriguez.) A study of lower-income mothers with children in Early Head Start shows that reading to very young children even before children have begun to identify letters can form an important foundation for vocabulary development and language skills later in life.
