This annual report presents several articles related to the work of the Clinical Center for Child Development at Hokkaido University in Sapporo, Japan. The articles are: (1) "Joint Attention as a System Property of the Infant-Caregiver Interaction System"(Tsuneda Miho and Shing-Jen Chen); (2) "Age-Related Change in Japanese Maternal…

The interactive creation of an attachment bond of affective communication between the psychobiologically attuned primary caregiver and the infant is central to human emotional development. These emotional transactions directly influence the experience-dependent maturation of the infant's early developing right hemisphere, which is in a growth…

In this paper some behavioral indices of attachment are defined and some of the factors that affect its development are considered. (Editor)

Effects of mothers' contingent and non-contingent vocal stimulation on vocalization and looking behavior was investigated in 10 Down's Syndrome infants. Neither condition increased infant vocalization but results suggest that looking behavior may be an important indication of competence in pre-linguistic social communication for developmentally…

Describes the Brazelton Neonatal Behavioral Assessment Scale, which is used to assess infants' competence in organizing their states of consciousness, interactive capacities, physiological responses, and environmental responsiveness. Various projects which have used the scale are reported. The predictive value and clinical uses of the scale are…

In follow-up studies conducted 36 hours, 3 months, and 12 months after delivery, maternal behavior, infant behavior, the duration of breast feeding, and attitudes toward child rearing procedures were shown to develop differently among mothers and infants receiving physical contact soon after birth as compared to control subjects who were briefly…

Explored infants' responses to live and replay interactions with mothers and their own images. Found that to their mothers, infants decreased attention, length of first gazes, and smiling from initial live feedback to replay, and that responses to subsequent live feedback generally remained suppressed. Also found that infants did not show a…

Examined whether the characteristics in perception of speech sounds found in preverbal hearing infants might extend to the perception of signed language in infants with congenital deafness. Seventeen Japanese mother-infant dyads participated in the study. Found that infants with deafness showed greater attentional and affective responsiveness to…

Assessed association between aspects of mother's employment and security of infant-mother attachment. Found that mothers' prenatal attitudes toward work and timing of work return made significant contributions to attachment outcomes apart from effects of maternal sensitivity, demographic, maternal, child, and child care factors. Mothers who…

Compared with fathers, mothers were more likely to pick up and hold infants, feed and comfort them, and invest time in displaying affection. Although there were sex differences in parents' rough and peek-a-boo play, mothers and fathers treated boys and girls quite similarly. (RH)

Investigated the universality of children's use of their mothers as a secure base. Found that, on average, children in all seven of the countries and contexts studied were characterized as using their mothers as a secure base, but that they differed across cultures in the degree to which their behavior conformed to the definition of a securely…

Reviews research on infants classified by Ainsworth's "Strange Situation" assessment as insecure/ambivalent, and examines studies exploring attachment theory beyond infancy. Presents a theoretical discussion of the ways in which patterns of mother and child behaviors associated with the insecure/ambivalent pattern may work together to…

Examined infant facial expressions at two, four, and six months of age during face-to-face play and a still-face interaction with their mothers. Contrary to differential emotions theory, at no age did proportions or durations of discrete and blended negative expressions differ; they also showed different patterns of developmental change. (MM)

Analyzed data from 11 studies of concordance of mother/father attachment to an infant based on the Strange Situation. Found that security of attachment, type of insecurity, and subcategory classification of security to one parent depended on the other parent. Discussed parenting styles and infant temperament. (BC)

Compares activities related to maternal organization of infant attention toward mother and the environment in Japanese and American mother-child dyads. Results reveal that the two cultures have both similar activity and interaction patterns and culture-specific patterns. (Author/BB)
