Abstract
The contributions of three variables—children's receptive vocabulary scores, maternal responsiveness, and maternal directiveness—to the prediction of Verbal IQ and reading over a 5½-year period were investigated. The study sample consisted of 543 low-birthweight children who were participants in the larger Infant Health and Development Program. Three separate multiple regression analyses found that children's receptive vocabulary scores at 36 months of age accounted for the major portion of the variation in the outcomes. Maternal responsiveness added significantly to the variation in each of the three models. The results suggest that the responsiveness of the mother is an important variable to consider when an intervention target is enhancing the verbal ability of a child.
