Examines claims about the role of object-sharing in development by describing development of !Kung infants' interest in objects and their caregivers' actions toward them when they are engaged in object-related acts. (PCB)

Attempted to replicate findings of a previous study which found that mother-toddler interaction during problem solving was related to the child's prior attachment security. Examined the relationship between problem-solving interactions on the one hand, and mother-child interactions at home and infant temperament on the other. (PCB)

No main effect relations between infant proneness-to-distress temperament at 9 months and attachment classification at 13 months were found. Proneness-to-distress temperament was associated with maternal behavior and personality. (PCB)

Infants were observed three times in the strange situation with their professional caregivers, mothers, and fathers to examine relationships between infant-parent attachment, day care characteristics, and the quality of infants' attachments to professional caregivers. (PCB)

Spontaneous peer interactions of toddlers paired in mixed- or same-age dyads were observed in an effort to see whether the toddlers would adjust their social behavior to the age of their partners. (PCB)

Examined (1) the possibility that children organize general statements into meaningful and consistent psychological concepts of themselves; (2) individual differences revealed in these concepts; (3) the possibility that these differences show stability over a one-month period. (PCB)

Children of 18 months classified as secure or insecure/avoidant by means of the Ainsworth Strange Situation were observed at home and in a playgroup. Teachers and observers rated girls classified as insecure/avoidant as being more difficult to deal with and having more difficulty with peers than girls rated as securely attached. (PCB)

The association between boys' peer relations, antisocial behavior, academic skill deficits, and family ecology was examined. Two cohorts of boys and their families were interviewed, observed in the home, and assessed in school. (PCB)

In this study of developmental precursors of adolescent behavior, the developmental trajectories of 435 boys from ages 3 through 15 were traced for selected correlates of delinquency (childhood antisocial behavior, low verbal intelligence, reading difficulty, and family adversity). (PCB)

Offers a developmental perspective on research risk that emphasizes the idea that some risks to children decrease with increasing age; some increase as the child matures; some change in a curvilinear fashion; and some remain essentially stable. Suggests that researchers are in an optimal position to safeguard children's rights. (RH)

Content analysis was used to assess the extent to which psychological theories and research about infants were communicated to parents from 1955 to 1984 in two popular publications, the "Infant Care Manual" and "Parents" magazine. Findings indicated that there was no singular relation between what experts knew and what was communicated to parents.…

At 3 years of age, children who had received food supplementation were an average of 2.6 cm and 642 grams larger than controls. Home visiting and supplementation combined reduced the number of children with severe growth retardation. Participants were 280 infants and their families from poor neighborhoods in Bogota, Colombia. (RH)

Data provide strong evidence that studies of stress and cortisol release in infants must take into account basal level, circadian rhythm, and behavioral effects and employ appropriate statistical procedures. Participants were infants of two, four, and six months of age from whom salivary cortisol was obtained before and 15 minutes after an…

Longitudinal data provide an encouraging base for further investigation of early individual differences in attentiveness and possible early precursors of later attention deficits. In the study, full-term and preterm children were observed at 1, 2, and 3.5 years in free play and in more structured situations. (RH)

Results indicated that six cries differentially affected subjects' affective, self-reported, behavioral responses and tendency to report not hearing the cry. Participants were 53 male and 65 female psychology undergraduates and 58 mothers who were exposed to one of six types of infant cries. Higher pitched cries elicited less optimal responses…
