This week’s blog was contributed by PAR Author Adele Eskeles Gottfried, PhD . Dr. Gottfried is the author of the Children’s Academic Intrinsic Motivation Inventory (CAIMI) . The study she describes in this blog is part of a broader investigation in which she examines the importance of home environment and parental stimulation on the development of children’s academic intrinsic motivation. In a longitudinal study spanning 28 years, new research just published in Parenting: Science and Practice examined the long-term effect of children’s home literacy environment during infancy and early childhood on their subsequent reading intrinsic motivation and reading achievement from childhood through adolescence and their educational attainment during adulthood. This type of motivation, which is the enjoyment or pleasure inherent in the activity of reading, is found to relate to various aspects of children’s literacy behaviors. Literacy environment was assessed from infancy through preschool using the amount of time mothers read to their children and the number of books and reading materials in the home. Analyzing the data using a statistical model, the study examined literacy environment as it related to children’s reading intrinsic motivation (measured with the Reading scale of the CAIMI) and reading achievement across childhood through adolescence and their educational attainment during adulthood. Results demonstrated that it was the amount of time mothers spent reading to their children—not the number of books and reading materials in the home—that significantly related to reading intrinsic motivation, reading achievement, and educational attainment. Specifically, when mothers spent more time reading to their children across infancy through early childhood, their children’s reading intrinsic motivation and reading achievement were significantly higher across childhood through adolescence. In turn, higher reading intrinsic motivation and reading achievement were significantly related to educational attainment during adulthood. These findings were found regardless of mothers’ educational level. The implications for practice are clear: Reading to children during infancy and early childhood has significant and positive long-term benefits, and this information must be disseminated. Mothers, fathers, and other caregivers need encouragement and support to read to infants and young children, and they need to know what a difference it will make to children’s intrinsic motivation to read and learn.
