This experiment examined whether newborn stepping, a primitive form of bipedal locomotion, could be modulated by optical flow. Forty-eight 3-day-old infants were exposed to optical flows that were projected onto a horizontal surface above which the infants were suspended. Significantly more air steps were elicited by exposure to a terrestrial…

Responds to Worobey and Brazelton's commentary on the author's assessment of a Brazelton-based newborn intervention by addressing two issues: (1) what the literature indicates with respect to this intervention technique, and (2) the significance of the process by which interventions are implemented. (HOD)

Families were compared at one, three, and nine months to examine the effects of active or passive exposure to the Brazelton Neonatal Behavior Assessment. Either the mother or both parents were the target of the intervention. Assessments of interaction behavior between parents and infants revealed no effects of the experimental intervention.…

Responds to Belsky's critique of the Neonatal Behavioral Assessment Scale and suggests explanations for the disparity in results when using the Scale as an intervention device with new families. (HOD)
