Examines mother characteristics, child behavior, and mother's temperament ratings when their babies were 4 months old. The social status, anxiety level, and mental health status of the mother were all related to temperament ratings on the Carey Infant Temperament Questionnaire. Results suggest that individual differences in mothers may be the…

This study applied Meehl's taxometric techniques for distinguishing latent types from late continua to Strange Situation data on 1,139 fifteen-month-olds from the NICHD Study of Early Child Care. Results indicated that variation in attachment patterns was largely continuous, not categorical. Implications of dimensional models for individual…

Examines the course of emotion expression development during the first 2 years of 58 full-term and preterm children through videotapes of mother/infant pairs. Mothers' contingency behavior appeared to have an effect on emotional development, as did birth status and gender. Prematurity was associated with differential socioemotional development.…

Examined effect of familiarization on 3.5-month-olds' retention of visual stimuli with varying delay times. Found support for retention models in which direction of attentional preferences (novel, familiar, or null) depends on memory accessibility. Short lookers showed better retention over time than long lookers, indicating that much of the…

This study was designed to investigate whether depressed mothers would show a predominantly negative affect or fail to provide a positive frame of experience for their babies. Two field studies of depressed mothers and their infants were conducted. A subgroup of 13 subjects and their babies from a larger project conducted in Cambridge…

This report is a portion of a study of attachment behavior: behavior promoting contact and/or proximity of an infant to his mother figure. This report deals specifically with crying, response to brief everyday separations from the mother and to her return, and behavior relevant to physical contact with her. The subjects, 26 infant-mother pairs…

A survey of assessment procedures of the newborn and of the infant during the first month of life was conducted; the survey indicated that there were instruments for evaluating the newborn and for evaluating the four-week-old infant, but there was no single procedure which included an evaluation of both the newborn and the four-week-old infant.…

Wary infants were more likely than bold infants to reference their mothers when the stimulus, a caged rabbit, was first presented; however, as the exploration period progressed, bold and wary infants referenced equally often. Referencing occurred less often than affective sharing. (RH)

Six children were visited in their homes every 2 weeks for 18 months from the age of 6 months to observe their developing comprehension and production of words. Results showed both similarities and individual differences in patterns of early comprehension. A close relationship was noted between early production and comprehension of words;…

Compared the attachment classification distributions of 23 infants in Israeli kibbutzim with communal sleeping arrangements with those of 25 infants in kibbutzim with home-based sleeping arrangements. Among the home-based infants, 80% were securely attached to their mothers versus only 48% of the infants in communal sleeping arrangements. (MDM)

Examined facial expressions in relation to cognition in infants 2 to 8 months of age. A total of 48 subjects received an audiovisual stimulus contingent on arm movement, whereas 32 infants did not control the stimulus. Infants in the contingent group expressed greater interest and joy during learning and greater anger during extinction. (RH)

Temperament development was studied in 39 full-term small-for-gestational-age infants and 30 full-term appropriate-for-gestational-age infants. Temperament was measured at 4, 8, and 12 months of age using a behavioral assessment procedure and questionnaire ratings. Findings indicated that restricted fetal growth negatively affects infant…
