Compares activities and interactions of Japanese and American mothers and their five-month-old infants in their natural home settings from a macroanalytic viewpoint in terms of mothers' verbal and visual stimulation of infants and infants' visual and tactual exploration and vocalization.

This case study provides early developmental data about a child later diagnosed as autistic. The report describes results of serial ultrasounds performed during the pregnancy, the complication of maternal diabetes, family history, high maternal stress levels, avoidance behaviors of the infant, and developmental delays exhibited especially in…

Infants who changed in levels of emotionality between three and nine months were compared with infants who remained stable. Maternal personality, marital factors, and mother-infant interaction accounted for the change in highly emotional infants. Father factors accounted for changes by infants who were initially low in negativity. (BC)

Compared cognitive functioning of infants--at 8 and 18 months--with varying levels of prenatal cocaine exposure. Found that, with risk and polydrug exposure controlled, exposure groups did not differ at 8 months on Bayley Scales or recovery to a novel stimulus. Infants with heavy exposure or high environmental risk declined in mental development…

Compared behavior of 52 Costa Rican 12- to 23-month-olds with iron-deficiency anemia to that of 139 infants with better iron status. Found that iron-deficient infants maintained closer contact with caregivers; showed less pleasure and playfulness; were more wary, hesitant, and easily tired; made fewer attempts at test items; and attended less to…

Investigated stability and change in infant affective responses to still-face interaction, impact of maternal depression, and whether infant responses predicted toddler problem behaviors. Found stable individual differences in gazing away and rates of negative affect. Gazing away increased over time. Mothers' current depressive symptoms and…

Previous work by our group has shown that infant emotional vitality (EV), the lively expression of shared emotion both positive and negative, predicts cognitive and language abilities in toddlerhood. Specifically, infants who demonstrated a pattern of high emotional expression combined with high bids to their caregivers, fared significantly better…

To study the social-emotional development of triplets, 23 sets of triplets, 23 sets of twins, and 23 singleton infants (N=138) were followed from birth to 2 years. Maternal depression and social support were assessed in the postpartum period, mother-infant and father-infant interaction and the home environment were observed at 3 months, a…

Four studies involving 40 pigtail monkeys are described in which relatively short separation experiences in infancy were associated with evidence of persistent changes in social behavioral function (less sociability, fewer close friends) and immunological function (suppression of lymphocyte proliferation) up to 6 years later. (Author/JDD)

Presents an overview of a developmental structuralist model based on integration of psychoanalytic and Piagetian developmental psychology. Includes discussion of patterns and insights from a clinical-descriptive intervention study of multirisk families and suggests lines for future research. (RH)

Presents an overview of social skill interventions with infants, toddlers, and preschoolers and emphasizes parent training approaches, dyadic (parent-child) therapy, and treatment which directly change the child's behavior. Discusses the range of services which could be provided within the community to foster social competence in young children.…

The infant's impressions of his environment are viewed by several philosophers, including Jean Piaget. There has been some past tendency to suppose that, prior to the acquisition of language, the infant has no real impressions about his environment. More recent understandings consider that the infant is capable of conceptualization and can express…

Suggests that since most newborn infants (65%) preferred to lie with their heads turned to the right, whereas 15% showed a distinct preference for the left, right head-orientation preference may contribute to the early development of right-handedness. (Author/SK)

Social interaction and play behavior were compared in community-based infant day care and at home for two matched groups of 18-month-old infants. Adult-infant, infant-peer, and infant-toy interaction were time-sampled. (Author/SS)

Two articles discuss problems that infant caregivers deal with in their work place. The first article provides ideas on how to take care of and pacify a crying baby; the second discusses the experience of a caregiver in a group child-care situation which involved her own child, noting the transition from infant room to toddler room.
