In this study designed to compare the relative pacifying properties of horizontal and vertical rocking, 13 infants (mean age--58 days) were each tested on two subsequent days. The rocking device was a cradle that could be manipulated to produce side-to-side rocking similar to a commercial cradle or up-and-down rocking. In its up-and-down mode, the…

The behaviors of narcotics-addicted and nonaddicted newborns in the first 2 days of life were assessed and compared. (JMB)

An exploration of the clinical usefulness of the Brazelton Neonatal Behavioral Scale was made. A specific pediatric problem was studied, i.e., a baby born to a heroin-addicted mother taking methadone. The control sample was a population of 41 babies who were part of a larger study. Both methadone and control infants were tested between 48 and 72…

The Carolina Record of Infant Behavior was used to assess the stability from 3 months to 1 year of such characteristics as activity level, irritability, and social responsiveness in 39 preterm infants at risk for developmental disorders. The most stability was observed on such developmentally based items as social orientation. (Author/JW)

Developed the Toddler Behavior Checklist (TBC) using parental reports of the frequencies of 103 patterns of behavior in children from 9 to 48 months old. Five scales were derived from factor analysis: Oppositional, Immaturity, Emotional Instability, Physical Aggression, and Shyness. Four scales demonstrated excellent reliability; reliability of…

A study of the effect of the twin sibling relationship upon interactions between monkey mothers and infants. Findings provided strong support for the prediction that the twin sibling presence decreases the amount of behavior directed from infant to mother. Differences in maternal behavior were concluded to be reactions to differences in infant…

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)

The research reported in this symposium paper attempts to underline a Piagetian distinction concerning object concept which has tended to be ignored by psychologists working along Piagetian lines. More specifically, this research tested the hypothesis that intellectual development plays a role in the development of stranger reactions. The subjects…

The Perception of Baby Temperament Scales (PBT) were used to elicit parental perceptions of infant temperament, with the results rated for internal consistency and congruence between parents. Data was obtained from 26 families, with both father and mother describing their first-born infants at five months of age. The PBT Scales deal with a range…

This report presents a cumulative risk score system designed to identify high-risk infants through multiple assessments over an extended period of time. The system scores prenatal, natal, and neonatal biological events and neonatal behavioral performance in an additive fashion. Infants are assessed in the first month of life to distinguish those…
