Observations indicate Black and White sixth-grade students interacted primarily with others of their own sex and race. Boys interacted more across racial lines than did girls, and Blacks were almost twice as likely as Whites to be the source of cross-race interactions. Peer behaviors were more likely to be task-related when directed toward White…

Compares patterns of friendship in infants, toddlers, and preschool children who attended either a child-care center or a program for emotionally disturbed children. Younger children had fewer and more stable friendships; emotionally disturbed children limited friendships to single partners. Complexity of social interaction increased most within…

Attention to others' activity increased with age in children ages four to six. Subjects who showed stable gains in performance level across sessions engaged in more observation of others' activity than did subjects who showed only temporary gains. Subjects who showed no gains observed others' activity least. (Author/RH)

A total of 73 children seven to eight years of age were videotaped as they interacted with a sibling in cooperative, competitive, and neutral situations. It was concluded that children's experience of the sibling relationship varies systematically with sibling status. (Author/RH)

Compares differences in the attachment behavior of infants from middle-class homes who were in day care full-time, part-time, or not at all. Results of a strange-situation procedure in a laboratory setting suggested that the length of daily separation appears to be an important determinant of day care effects on infant/mother attachment.…

Reviews the history of the developmental study of infants and children at biological risk and appraises the current state of the art. Four research phases during the period from 1920 to the present are identified, each reflecting aspects of the social, political, health, and psychological zeitgeist. (Author/RH)

Maternal alcohol use in mid-pregnancy was significantly related to poorer habituation and increased low arousal in newborn infants, even after adjusting for smoking and caffeine use by mothers, maternal age and nutrition during pregnancy, sex and age of the infant, and obstetric medication. (Author/RH)

The tape-recorded cries of low- and high-risk newborn infants were rated by 150 inner-city Anglo-American, Black-American, and Cuban-American mothers during the hospital lying-in period following childbirth. Reliable differences were found between low- and high-risk infant cries on all of four perceptual responses, with culture and parental…

Describes a model of risk potential for developmental outcome that was based on cardiac, medical, surgical, and family stress factors in 31 children with transposition of the great arteries. All children had undergone reparative open heart surgery utilizing cardiopulmonary bypass during infancy. (Author/RH)

Tests the hypothesis that developmentally delayed children differ from normal children on tasks involving discernment of nuances, balancing competing stimuli, or acquiring and retaining selected information. Attention deployment behaviors in a free-play situation were examined for three groups: normally developing, Down syndrome, and…

Tests the hypothesis that appropriately timed stimulation provided to preterm infants would aid self-regulating and lead to quiet sleep. It was expected that effects of self-regulation would be evident in infant development interaction and performance. Stimulation consisted of a gentle horizontal movement and a heartbeat sound presented on…

Examines the level and quality of object play and other cognitive and socioemotional aspects of the play situation, both as individual entities and as interrelated aspects of the way the child with Down syndrome approaches and deals with the animate and inanimate world. Relationships among these aspects and the child's level of functioning were…

Examines (1) whether and when the development of preterm children of very low birth weight would begin to approximate that of demographically matched full-term children, and (2) whether test scores corrected for degree of prematurity or those based on chronological age would be the more accurate predictors of subsequent development. (RH)

Investigated the effect of increasing familiarization time on the visual recognition memory of 6- and 12-month-old full-term and preterm infants. Results suggested that persistent differences exist between preterm and full-term infants throughout at least the first year of life in this fundamental aspect of cognition. (Author/RH)

Results support previous findings of interactional differences during early infancy between mother/premature and mother/full-term infant dyads. Preterms performed significantly below full-terms on measures of cognitive and language development corrected for gestational age. (Author/RH)
