Considers contributions of Sigmund Freud and Rene Spitz to developmental psychology. Freud's contributions include his observations about play, perspectives on developmental processes, and ideas about unconscious mental activity. Spitz's contributions include his assessments of infants, perspectives on developmental processes, and his concept of…

Examined whether links between the marital relationship and sibling interaction were directed or mediated by the mother-child relationship. Found that older siblings' negative behavior was linked with negative dimensions of the marital and mother-child relationship. Younger siblings' negative behavior was linked with the mother-child and…

Examined security of attachment between pairs of young children and their mothers and fathers in maritally intact families. Found that younger and older children developed concordant attachments to both parents. Parents were consistent in caregiving to their two children. Associations were found between maternal caregiving and attachment only for…

Effects of maltreatment were examined in three domains suggested by attachment theory: relationships with novel adults, effectance motivation, and cognitive maturity. Three samples of four- to eight-year-old children were studied: 93 maltreated children, 67 demographically matched nonmaltreated childen, and 30 nonmaltreated middle-class children.

Examines associations among contemporaneous measures of marital quality, parenting attitudes and behavior, and toddler development in two-parent families. Seventy-five families with one 20-month-old child served as subjects. Results generally indicated that good marital quality was associated with optimal toddler functioning and sensitive…

Three studies explored the connection between attachment and peer-related representations among children from preschool age through grade five. Found that children secure in their attachment to their parents had more positive peer feelings than did insecure children, and greater perceived rejection by both mothers and fathers was associated with…

Investigated development of face-to-face communication in infants between 1 and 14 weeks old and their mothers. Found a curvilinear development of early face-to-face communication, with increases occurring between weeks 4 and 9. When placed on a sofa, infants' face-to-face communication was longer than when they were held. Girls spent a longer…

Relations between maternal depression and attachment among 50 infant-mother and 54 preschooler-mother dyads were examined using several attachment measures. Attachment insecurity was found to be significantly associated with maternal depression among infants and preschoolers. Children without unitary, coherent attachment strategies tended to have…

A study of 53 Japanese mothers and their young children who were temporarily living in the United States found that, when life stress was high, mothers reported less parenting stress if social support was adequate. The more satisfied mothers were with their support, the less secure was their children's attachment. (BC)

Examined Attachment Q-Set security scores as indexes of attachment security. Found that Q-Set scores (1) related positively to sensitive mothering and preschoolers' sociability toward mother during laboratory observations; (2) related negatively to children's negative affectivity during free play; and (3) were associated with levels of parenting…

Examined mother-child relationship and child fearfulness at 8-10 months and 13-15 months in relation to child attachment at 13-15 months. Found that the mother-child relationship, and 13-15 months only, predicted child security versus insecurity but not the type of insecurity. Child fearfulness was unrelated to security versus insecurity, but…

Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation. Therefore, the authors explored sensitivity as a…

Preschool to school-age trajectories of 242 children, including 37 with insecure-disorganized and 66 with insecure-organized attachment patterns, were examined. Child attachment and stressful life events (the latter retrospectively) were measured at ages 5-7, and mother-child interactive quality, parenting stress, marital satisfaction, and…

This study examined differences in the caregiving representations of mothers of 3- to 4-year-old behaviorally inhibited and uninhibited children with secure or insecure attachments. Mothers of inhibited children perceived their children as more vulnerable than did mothers of uninhibited children, and they acknowledged difficulties associated with…

Distress in response to brief maternal separations was examined in a sample of 93 predominantly home-reared infants using the Ainsworth strange situation paradigm. At 18 months, the age when separation protests begin to decline, securely attached infants are better able than anxiously attached infants to tolerate maternal separations. (Author/RH)
