Summarized in this book are conference presentations focusing on new approaches to developmental screening of infants and strategies for early intervention with children at-risk. Summaries concerning assessment describe characteristics of an "optimality scale" for neurological assessment; a five-step neurological assessment for evaluating gestational age; use of gestational age, birth weight, and head circumference in assessing newborns; use of the Brazelton Neonatal Behavioral Assessment Scale (NBAS) in studying neonatal change; and use of the NBAS and the Assessment of Preterm Infants' Behavior to study infants' individuality. Also discussed are a model of early infant development, Brain Electrical Activity Mapping (a new technique for neurophysiological assessment), a prescreening device for populations of low socioeconomic status and a home environment questionnaire, and problems in and prospects for predicting developmental outcomes. Summaries concerning intervention strategies discuss programs for infants with cerebral palsy; early intervention for preterm infants; an ecological approach to parent/child relationships; intervention strategies using temperament data; relationships among health, development, and behavior in the young child; and a sensorimotor enrichment program. Selected responses of some participants to each presentation are included at the end of each summary. (RH)
