Both early childhood maternal language input and the quality of classroom instruction in elementary school have been shown to be important environmental supports in predicting children's literacy skill development. However, no studies have simultaneously examined these two environmental supports in relation to children's early language skills and…

Background: Even infants can recognize whether patterns of motion are or are not natural, yet an acknowledged challenge for science education is to promote adequate reasoning about such patterns. Since research indicates linkage between the conceptual bases of recognition and reasoning, it seems possible that recognition can be engaged to support…

The child population in the United States is rapidly changing and diversifying--in large part because of immigration. Today, nearly one in four US children under the age of 18 is the child of an immigrant. While research has focused on the largest of these groups (Latinos and Asians), far less academic attention has been paid to the changing Black…

Continuity in relationship representation and developmental links between relationship representation and behavior from infancy to late adolescence were examined using longitudinal data from a risk sample (N185). Significant correlations were found among diverse representational assessments (e.g., interview, drawing, projective narrative) and…
