INCREASING attention is being focused on the development of infants restricted in intrauterine growth. Whether such restriction at a critical period of maturation affects brain development and function has not been adequately determined. The present study was designed to determine if term infants who were undersized at birth and without evidence of fetal infection or malformation differ from larger infants of comparable maturity in their general intellectual performance at the preschool level.
