Following Meltzoff's (1995) behavioral reenactment paradigm, this study investigated the ability of 12-month-olds (N = 44) to reproduce a model's attempted-but-failed actions on objects. Testing was conducted using a novel set of objects designed to enable young infants to readily identify the potential outcome of the model's actions. Infants who…

This study examined whether 19-month-old-infants' social understanding was related to their interaction behavior during dyadic cooperation with a peer. Toddlers' ability to predict others' action intentions was examined using a computerized experimental task. The children watched a series of stimulus movies in which an actor expressed her liking…

Investigates the degree to which object familiarity and motivational factors influence infants' search behavior in an object-permanence test. (Author/MP)

Compares infants' performance based on chronological age as opposed to conceptual age. The Bayley Mental Scales were used to test 20 premature experimental infants and 20 full-term control infants. Results demonstrated that an infant's performance must be judged on the basis of conceptual rather than chronological age. (MS)

A study was conducted to investigate the degree to which both object familiarity and motivational factors influence infants' search behavior in an object permanence test. Infants' search behavior for an unfamiliar test object was compared with search behavior for (a) an experientially familiar object that each infant had played with daily for a…

Ten preterm infants in a neonatal intensive care unit were provided with tactile-kinesthetic stimulation. Following treatment, the infants' weight gains and performance on the Neonatal Behavioral Assessment Scale significantly increased, compared to 10 control-group infants, also preterm. The groups showed no differences on length of hospital…

In a study to assess young children's social interaction with peers, six male toddlers who were the only participants in a playgroup were observed in two situations: (1) a GROUP situation in which at least four of the boys were present and (2) a DYAD situation in which only two boys were present. Both types of observations were made at 16, 19, and…

The original Bayley Scales of Infant Development (BSID) have been among the most popular measures of performance and aptitude of infants. In this study, the construct validity of scores on the Behavior Rating Scale of the revised Bayley Scales, the BSID-II, was investigated using national standardization and clinical samples of children ranging in…
