Assessed behavioral and physiological differences between 61 breast-fed and 39 bottle-fed neonates. Mean postpartum assessment occurred at 37 hours.

Discusses the accuracy and interpretation of the ponderal index, reiterating that Lester et al. suggested a hypothesis, not a proof, that low birth weight, combined with maternal obstetric drugs, negatively affects…

Examines the psychometric properties of two procedures for reducing data from the Brazelton Neonatal Behavioral Assessment Scale: factor and cluster analysis. The sample consisted of 85 male and 77 female newborns. (RH)

Forty-eight neonates were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. Results indicate that vestibular proprioceptive stimulation, provided horizontally or semi-vertically, significantly enhanced visual tracking.…

Reports the results of studies of perception of very young infants. Sixty infants 6 to 23 days old were presented objects; looking-at and reaching-for the objects were measured. Results indicated active visual exploration of objects did occur; however, little motor activity was directed toward the objects. (SL)
