Male infant vocalizations were studied as a function of age. (JMB)

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

Results offer empirical support to Ilg and Ames's claim that the Gesell battery is an excellent predictor of school readiness. The close similarity of the Piaget and Gesell tests accords well with previous findings that the two tests have much in common. (Authors/MB)

The comparative value of various parameters of neonatal prematurity for differentiating intellective, scholastic, and social functioning in middle childhood was assessed for a sample of 38 prematurely born and 26 maturely born subjects aged 7 to 9.5 years. (Author/JMB)

Critically evaluates in terms of predictive and concurrent validity a widely used method of identifying children at risk in peer relations. This method emphasizes children's total rate of peer interaction, regardless of the quality or skillfulness of the interaction. Recommendations are given for future research in this area.

Specific aim of the study was to determine the predictive accuracy of selected observations obtained during developmental periods on later developmental outcome. (Authors)

A possible interpretation of the differential predictability across school systems as revealed in this study, is offered. (Authors/MB)

Longitudinal observations of maternal and infant characteristics were used to investigate the consequences of early day care intervention for infants at high risk for intellectual retardation due to sociocultural factors. (JMB)

This review of literature on infant habituation and recognition memory performance as predictors of later IQ concludes that the level of prediction is (1) substantial; (2) higher for at-risk than nonrisk children; and (3) not higher than the level of predictions based on parental education and socioeconomic status.

The behavioral development of rural Guatemalan infants was assessed shortly after birth on a Neonatal Assessment Scale (NAS) and at 6-, 15-, and 24-months-of-age on a Composite Infant Scale (CIS). Summary variables based on NAS performance poorly predicted later assessed performance even as recently as six months after birth. The CIS modestly…

The MacArthur-Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N=113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and…

Results indicate that the Home Observation for Measurement of the Environment (HOME) Inventory might be useful for screening Black children in order to identify those at risk for school failure. (Author/RH)

Examined relations among measures of child language derived from observations of 20-month-olds' speech with mothers, experimenter assessments, and maternal reports. Found that structural equation modeling supported strong relations among the three sources, the loading of multiple measures on a single latent construct of vocabulary competence, and…

Scores on the Home Observation for Measurement of Environment (HOME), designed to reflect parental support of early cognitive and social development, were correlated with elementary school achievement five to nine years later. Results supported the predictive value of the instrument for school achievement among low-income families. (Author/DB)
