A study of the relationship between pain-relieving drugs given to mothers during labor and delivery and neonatal behavior as assessed by the Brazelton Scales. Tested 44 infants on eight different days during their first month of life. (SDH)

The ability of 1-month-old infants to recognize their mothers visually was explored with the live faces of mother and stranger presented in three different poses: en face (full face), half-profile, and profile. Subjects were 16 infants with normal Apgar scores at birth who were volunteered by their parents after an initial contact in a maternity…

This research project, designed to examine social learning in infancy, attempted to examine the process of infant interaction through its beginning, middle, and end. Pairs of previously unacquainted 21-month-old children were observed in a laboratory playroom for 15-minute sessions on three consecutive days; on the fourth day, new dyads were…

The presentations and tables in this document deal with the development of mastery motivation from infancy to early preschool years. Discussion was focused on three questions: (1) whether mastery motivation can be measured in infants and young children; (2) whether it is possible to distinguish mastery motivation from cognitive functioning; and…

Parental sex-typed perceptions of infants at two different ages were examined in this study. Twenty-nine primiparous couples were recruited from a local hospital where they had been participating in various childbirth and child-care education programs. Sixteen were parents of boys, and 13 were parents of girls. First when their children were 5 to…

Mothers' imitation of their infants during the first 3 days of life is examined in this study. Twenty-four newborn infants (12 males, 12 females) and their mothers participated in the study. On each of the first 3 days following delivery, mother-infant pairs were videotaped in a non-feeding interaction for approximately 5 minutes while the infants…

Sharing behaviors of infants who had experienced early separation through hospitalization from their mothers were compared to behaviors of infants who had experienced no such separation. Responses of the mothers to their infants' prosocial behavior were also analyzed. Subjects were twenty 1-year-old infants and their mothers. On the basis of the…

This study identifies elements in the attachment behaviors of 7-month infants which predict the quality of their attachment to their mothers at 13 months. At 7 months 147 infants were observed (and videotaped) during a free play period with their mothers present, during a separation from their mothers and then during a reunion period. At 13 months…

The main purpose of this paper is to delineate methods of data collection and coding currently being used in a longitudinal observational study of toddlers in 25 black families in Oakland, California. Data collection activities, accomplished through monthly three-hour visits to each home, focused on five types of data: (1) videotaped and…

Reports on research conducted to asses the utility of physiological responses for both the prediction of individual differences in attentional capacity and the monitoring of developmental changes in attentional responsivity. Specifically the experiments assessed: (1) Heart rate variability and newborn heart rate responses to illumination changes,…
