Measures of visual alertness, irritability, and activity based on repeated observations in equivalent situational contexts showed good intersession stabilities, which were consistently higher than measures based on lengthier over-all session observations, and substantially higher than stabilities typically reported for measures of newborn…

Examines research on infants who experience risks in the prenatal or perinatal period. Focuses on the evolution of the studies and the knowledge gained over the last three decades, contemporary research efforts and pertinent issues, and directions for future research. (RJC)

Examines evidence on the effects of perinatal and postnatal factors (e.g., anoxia and child abuse) on later development to determine if causality exists. The inadequacies of current developmental models are discussed. (BRT)

Explores differences in temperament of preterm and full-term infants at three and six months of age. Preterm infants were generally rated more difficult than full-term infants at both ages. All infants were generally rated less difficult at six than at three months. (Author/BB)
