This study examined the stability of three patterns of infant regulatory behavior identified in the face-to-face still-face (FFSF) paradigm at 3 and 9 months--social-positive oriented, distressed-inconsolable, and self-comfort oriented--and whether variations in infants' heart-rate were correlated with them. Although some studies have examined the…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…

Quantifies behavioral periodicities or cycles during face-to-face interaction between three- and five-month-old term and preterm infants and their mothers. Compares the temporal organization of social interaction between term and preterm infants. Spectral and cross-spectral techniques showed the existence of periodicities. Differences were found…

Links between neonatal biological rhythms and the emergence of interaction rhythms were examined in 3 groups (N=71): high-risk preterms (HR; birth weight less than 1,000 g), low-risk preterms (LR; birth weight=1,700-1,850 g), and full-term (FT) infants. Once a week for premature infants and on the 2nd day for FT infants, sleep-wake cyclicity was…

Analyzed effects of modeling and contingent praise on infant imitation of three responses: motor-with-toy, motor-without-toy, or vocal. Found a systematic increase in the percentages of training and probe models matched by the three 12- to 14-month-olds following introduction of model-and-praise treatment conditions. Nonmatching responses did not…

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)

Portions of this paper were presented at the 1967 meeting of the Society for Research in Child Development, New York.

Sixty infants (ages 11 to 26 weeks) were divided into 3 groups (healthy, preterm healthy, and preterm sick). Ten minutes of infant-parent interaction were videotaped, and mothers viewed the tapes and identified infant behaviors they interpreted. Differences in behavioral interpretations among mothers are identified, as are correlations among…

This paper presents arguments for greater use of sophisticated research strategies and statistical analyses of data in dealing with the real-life complexity of social interaction. Three possible procedures are proposed and illustrated in a study of interactions between mothers and their 8- to 18-month-old children. The first strategy is to…

Examines the validity of a maternal rating scale for pacifier-attachment in a laboratory setting. Once mothers' abilities to assess their children's attachment behavior were ascertained, a second study was designed to contrast the patterns of attachment to pacifiers, blankets, and hard objects in children between 1.5 and 63 months.

Studies the communication of affect between depressed mothers and their infants and its relation to infant socioemotional and cognitive development through face-to-face interaction. Findings indicate that there are correspondences between the behavior of depressed mothers and their infants. (Author/BB)

Reviews recent research on mother-infant communication that takes into account both the infant's and parent's influences in interactions. Topics discussed include varieties of infant communications, cross-cultural research, the beginnings of communication patterns, assessment of communication effectiveness, and sequelae of differing mother-infant…
