Intellectual Development within Transracial Adoptive Families: Retesting the Confluence Model.
Peer reviewed Peer reviewed
Berbaum, Michael L.; Moreland, Richard L. – Child Development, 1985
Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

The Confluence Model and Theory.
Peer reviewed Peer reviewed
McCall, Robert B. – Child Development, 1985
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)

EEG Patterns of Preterm Infants, Home Environment, and Later IQ.
Peer reviewed Peer reviewed
Beckwith, Leila; Parmelee, Arthur H. Jr. – Child Development, 1986
Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)

Type of Day-Care and Preschool Intellectual Development in Disadvantaged Children.
Peer reviewed Peer reviewed
Burchinal, Margaret; And Others – Child Development, 1989
Investigates levels and patterns of intellectual development of 131 socioeconomically disadvantaged children in university-based intervention group day care or community day care, or with little or no day care.

Biological Nonoptimality and Quality of Postnatal Environment as Codeterminants of Intellectual Development.
Peer reviewed Peer reviewed
Breitmayer, Bonnie J.; Ramey, Craig T. – Child Development, 1986
A four-and-a-half-year longitudinal experiment reconsidered the contribution of organic impairment to the genesis of mild mental retardation among disadvantaged children. It was hypothesized that nonoptimal perinatal conditions might result in deficits that increase a child's vulnerability to environmental risk factors. Study results supported the…
