Videotapes of 50 mothers interacting with each of two siblings when each child was 12 months old showed that mothers behaved very similarly towards the siblings. Results suggest that differential maternal treatment of children at the same age in infancy is unlikely to be a major source of observed marked individual differences in siblings.…

Compares attachment relationships of infants at 12 months to their visual self-recognition at both 18 and 24 months. Individual differences in early attachment relations were related to later self-recognition. In particular, insecurely attached infants showed a trend toward earlier self-recognition than did securely attached infants. (Author/NH)

Reports a short-term longitudinal study of children at 13 months and at 18 months which supports the belief that patterns of emotion reflect early, persistent individual differences; they also reflect a developmental trend toward increasing complexity of emotional responses. (Author/NH)

A total of 114 infants at three age levels (11, 18, and 28 weeks) were rated by their mothers on a termperament questionnaire and subjected to a habituation procedure. Results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.…

Habituation to single female faces and to single geometric patterns was observed separately in two groups of infants who participated in two sessions separated by 10 days. Habituation was found to be distributed into three patterns and showed moderate but significant reliability between assessment sessions. (Author/RH)

Studies 12- to 24-month-olds in a series of videotaped tasks assessing single object manipulation, relational play, pretend play, distractibility and persistence. Develops eight relatively subtle measures of three aspects of individual differences in infant behavior: developmental level, attention span, and exploratory diversity. (Author/NH)

Delay/response inhibition in the presence of an attractive stimulus and compliance with maternal directives in a clean-up task were observed among subjects 18, 24, and 30 months of age. Results suggested (1) achievement of self-control is a major developmental accomplishment, and (2) individual differences in self-control emerge and are…

Investigates the relationship between self-recognition and self-evaluative emotions in two studies on 27 children aged 9-24 months and 44 children aged 22 months. The results of both studies indicate that embarrassment but not wariness was related to self-recognition. (RJC)

Results suggest that various aspects of Strange Situation behavior are related to both maternal and infant temperament, and that maternal temperament is a predictor of attachment security, particularly for Type A mother-avoidant infants. (Author/RH)

Provides overview of attachment theory as parented by John Bowlby in "Attachment and Loss". Uses two major concepts from this work to interpret refinements and elaborations of attachment theory attibuted to Mary Ainsworth. Considers how recent insights into development of socioemotional understanding and development of event…

Indicates that the Bayley Scales are a useful assessment tool for characterizing the behavior of premature infants. Results further indicate the need for going beyond summary scores of mental and motor performance and assessing performance in specific areas to obtain a more meaningful picture of individual infants' development. (RH)

Reports findings of a cross-sectional study and a longitudinal study of infants' and toddlers' interaction with their mothers. Findings indicated active structuring of vocal interaction by the end of the infant's second year; gaze began to approximate the typical adult pattern of signaling as early as 18 months. Implications for theory and…

Investigated continuities in mother-infant interaction observed at home, maternally perceived infant difficulties, and infant developmental competency. Also assessed were background characteristics and possible variables moderating maternal report of satisfaction with adjustment. A total of 128 dyads were assessed when infants were 6 and 13 months…

Data from four studies answer Carey's (1982, 1983) critical questions about the validity of the original Infant Temperament Questionnaire (ITQ). Discussion illuminates the complexity of establishing the construct validity of psychological assessments used with infants. Data suggest that both the original and revised Carey ITQs fail discriminant…

Investigated predominant kinds of parent-infant play and individual differences in play style. Participants were 24 families of healthy, full-term, firstborn infants, four boys and four girls at each of three ages: 7, 10, and 13 months. (RH)
