Weekly observations documented developmental changes in mother-infant face-to-face communication between birth and 3 months. Developmental trajectories for each dyad of the duration of infant facial expressions showed a change from the dominance of Simple Attention (without other emotion expressions) to active and emotionally positive forms of…

According to attachment theory, the quality of care plays a key role in the organization of infants' secure base behavior across contexts and cultures. Yet information about attachment relationships in a variety of cultures is scarce, and questions remain as to whether Ainsworth's conceptualization of early care quality (sensitivity; M. D. S.…

Fourteen-month-old infants saw an object hidden inside a container and were removed from the disappearance locale for 24 hr. Upon their return, they searched correctly for the hidden object, demonstrating object permanence and long-term memory. Control infants who saw no disappearance did not search. In Experiment 2, infants returned to see the…

This study investigated whether behavioral inhibition is best conceptualized as a continuous variable or as a distinct typology with two or more subcategories. The following data were gathered on 58 infants at 5, 7, 10, and 13 months of age; physiological functioning (cardiovascular activity and salivary cortisol); emotional expressivity in…

To make the point that infant emotions are more dynamic than suggested by Differential Emotions Theory, which maintains that infants show the same prototypical facial expressions for emotions as adults do, this paper explores two questions: (1) when infants experience an emotion, do they always show the corresponding prototypical facial…

This paper discusses the development of instruments to measure individual differences in behavior during infancy. The Infant Temperament Questionnaire (ITQ), which was designed to measure the temperament dimensions identified by the New York Longitudinal Study (NYLS), constituted the methodological starting point in the search for a dimensional…

This exploratory study investigated whether the Brazelton Neonatal Behavioral Assessment Scale (NBAS) can predict an infant's behavior on mastery motivation tasks at 1 and 2 years of age. Subjects were 31 normal, full-term infants from white, mostly middle class families. Infants were assessed using the NBAS with Kansas Supplements (NBAS-K) at a…

This study examined whether cry acoustics enhance the prediction of developmental outcome in preterm infants, after accounting for medical and social variables. Selection criteria for 149 preterm subjects included being born at less than 35 weeks gestational age and less than 1,500 grams; for 25 term subjects, selection criteria included being…

Four experiments investigating the effects of physical and social variables on the production of pointing in infants 10 to 18 months old are described. In the first two experiments, which were primarily concerned with the relation between reaching and index finger pointing, physical dimensions such as distance between baby and target objects were…

Through discussion and illustrative events, an evolving segment of communication is described during the course of transition of one child's total communication system from the sensorimotor or gestural level at 12 months into the level of use of the adult words "more" and "mine," and associated utterances, at 24 months.
