Growing evidence has linked center-based early care and education settings to improvements in children's cognitive skills. Additional research is needed to more carefully delineate when and for whom these associations are most pronounced. Using data from the Early Childhood Longitudinal Study, Birth Cohort (N ˜ 6,350; Flanagan & West, 2004),…

Longitudinal genetic analyses indicated substantial heritability of verbal delay from 2 to 3 years, especially in combination with performance delay. Results suggest a strong genetic contribution to verbal delay…
