Results suggest that the mother-infant-sibling interactive context differs in important ways from the mother-infant dyadic context. The mother-infant-sibling interactive context is a richer language learning environment than previously supposed. (GLR)

Describes the development of a case management program for children at the Center for the Vulnerable Child at Children's Hospital in Oakland, California. Case management was introduced into multidisciplinary clinical programs for foster children, drug-exposed infants, and adolescent mothers and their infants. (PAM)

Examined 114 pairs of same-sex infant twins and their parents to investigate infant predictors of adult IQ. Found that some measures of infants' information processing, language ability, and temperament predicted the average IQ of infants' parents. Results support the view that some stability in certain types of intellectual functioning from…

This study documented communication behaviors of 18 hearing mothers and their infants with hearing loss, at 12 and 18 months old, and compared these behaviors with those of 18 mothers and infants without hearing loss. Both groups were similar in quantity of gestural and vocal expressive prelinguistic communication behaviors but not in formal…

Forty-eight male infants (tested at ages three and four months) experienced either conversational turn-taking or random responsiveness of their mothers. Contingency did not affect the infant's rate of vocalizing but influenced its quality and timing. Intervals at which mother delivered contingent responses were longer when infant was older.…

Fourteen five- and nine-month-old infants were presented with illuminated toys to reach for in total darkness. In half the trials, a luminescent marker was attached to the reaching hand. The nine-month olds reached just as accurately with or without the hand marker, whereas five-month olds were generally inaccurate and unaffected by the marker.…

Using a dynamic systems approach, examined the development of intralimb coordination over the first year of independent walking in three infants. Found that, in the first month of walking, there was much instability between the thigh and shank of the leg, but after three months infants appeared to have found an adult-like stable coordinative…

Verbal and musical stimuli were presented to infants in a study of the relations of evoked potential left-right amplitude asymmetries to gender and hand preference. There was a relation between asymmetry and hand preference, and for girls, between asymmetry and stimulus condition. Results suggest a gender difference in cerebral hemisphere…

Relations among age appearance, facial attractiveness, and adult expectations of infants' developmental maturity were examined in three studies. Adults judged unattractive infants to be older and capable of more specific developmental skills than attractive infants but rated their general competence to be lower. (BC)

This study analyzed data from a diary study of a child's lexical development. Correct forms and errors in the use of the plural morpheme were recorded from 18 to 30 months. Morphology was acquired before syntax, and there was evidence for a syntactic definition of noun by the age of 20 months. (BC)

Discusses the following barriers to reducing the infant mortality rate: (1) fragmented and bureaucratic federal prenatal care programs; (2) insufficient number of rural public health clinics and private practitioners willing to serve low-income expectant mothers; (3) lack of health insurance; and (4) the high-risk behavior and motivation of…

Describes federally funded personnel preparation project supporting implementation of educational and clinical sequence in handicapped, medically complex, and at-risk infant and toddler specialization. Addresses vehicles of professional development, including courses and seminars, clinical rotations, and research activities. Discusses implications…

Draws on child-care-quality research to inform our understanding of quality in early-intervention services for infants and toddlers with disabilities and their families. Presents conceptual issues in defining quality and methodological challenges for assessing quality of early-intervention services. Discusses efforts to design a measure of quality…

Observed 193 children at 4.5 years who had been classified at 4 months as high or low reactive to stimulation for signs of inhibited or uninhibited behavior. Children classified as high reactive were less spontaneous and less sociable than low-reactive children, but only a small proportion maintained a consistently inhibited or uninhibited…
