Variables from three categories were inspected as correlates of HOME (Home Observation for Measurement of the Environment) inventory ratings for 43 severe perinatal risk or developmentally disabled infants at 8 to 9 months postexpected date of delivery. (Author)

A reliable clinical taxonomy of illocutionary acts for young language learning children was determined and the distributions of those illocutionary acts in naturalistic play situations with 12 Down syndrome and nondelayed children (20 to 89 months) and their mothers were examined. (Author)

In two studies, photographs of facial expressions of normal and Down's syndrome infants were viewed by mothers who recognized discrete emotions and reported regularities in caregiving associated with these emotions. Stimulating interactions were reported more frequently for high intensity expressions than for low intensity expressions. High…

Confirms that aftereffects of prism adaptation can be obtained in infants between 5 and 9 months of age and that the magnitude of these aftereffects is comparable to those found in adult studies. Evidence of a shift in hand preference toward the direction of prism displacement was replicated. (Author/RH)

Infants were observed at 10, 12, and 14 1/2 months to test whether social interaction among infant peers develops as a by-product of object-centered play. Age differences were noted. Object-centered contact did not influence early social interaction; long interactions emerged at later ages regardless of whether or not toys were present. (Author/DB)

This study was designed to investigate the development of the visual placing response in infants, as well as the visual mediation of the response and texture factors that influence this response during its development. The response was associated with age and apparently developed in two phases. (Author/DB)

Nine- and 16-month-old infants were presented a manual search problem in which a toy was hidden in one of two inaccessible containers, which were then moved into reach. Older infants performed better than younger infants, performance improved across trials, and more correct searches occurred when containers or trajectories were distinctive.…

Identified shortly after birth, Down's syndrome babies will represent a substantial number of infants in need of early intervention services. Direct contact with parents of Down's syndrome infants can provide professionals with opportunities to share new genetic findings that may assist parents in adjusting to the birth of their handicapped child.…

To assess the effects of the onset of mothers' inaccessibility to their infants, infant-mother pairs were observed in the Ainsworth strange situation at both 12 and 18 months and were classified as secure, anxious-avoidant, or anxious-resistant. Children of mothers who had returned to work/school before their child was 12-months-old were more…

Training was found to increase both parents' and infants' competence in the parent-infant dyad. A reciprocal relationship between increases in the trained fathers' interactions and decreases in the trained mothers' interactions was found, indicating that the triad may be the crucial unit for studies of parental competence.

Evaluates the effects of continuous lumbar epidural anesthesia on the newborn and on the developing mother- infant relationship. (Author/MP)

Investigated the relationship between anthropometric indices and behavioral development during the first two years of life in rural Guatemala. Body length and weight most strongly correlated with behavioral development. When length and weight were controlled statistically, variance in behavioral development was accounted for. (Author/DB)

Studies the distribution of attention to actors in a visual event and the influence of linguistic variables on attention. Naming an actor had a strong directing influence on attention in a neutral period and more limited effects on attention during and after the action. (RMH)

Critiques previous research concerning differences in voice onset time discrimination between Spanish and English infants and conclusions about the effect of early linguistic experience on speech perception. (RMH)
