For 152 children, intelligence scores were assessed at 4 and 13 years of age, and the number of factors out of 10 social and family risk factors was counted. The presence of multiple risk factors in children's lives explained up to half the variance of children's IQ scores at 4 and 13 years. (MDM)

Written in response to an article (Horn, 1983) that appeared in special Developmental Behavioral Genetics section of CHILD DEVELOPMENT (Volume 54), this commentary (1) notes some issues concerning Horn's analysis and interpretation of data and (2) highlights the potential for interpretational bias in behavior genetics research. (Author/BE)

In this rebuttal to Walker and Emory's commentary (also in this issue), Horn argues that the issue of the influence of environment on the average IQ of adopted children was well discussed in his article (Volume 54 of CHILD DEVELOPMENT). (BE)

Findings demonstrated that the Guilford-Mednick conceptualization of original thinking is applicable to preschool as well as to older children. (Author/RH)

Examined risk factors of 3-year-old sons in 58 families with alcoholic fathers and 16 families with nonalcoholic fathers. Found that sons of alcoholic fathers were more impulsive than sons of nonalcoholic fathers. No differences between the groups in developmental age, IQ, or behavior problems were found. (MDM)

Children whose mothers were consistently more responsive during the children's infancy and early adolescence achieved higher IQ and arithmetic scores, had more positive self-esteem, and were reported by teachers to exhibit fewer behavior problems than children of mothers who were consistently less responsive.

Two studies examined the relation between current developmental levels, as estimated by IQ, and proximal levels of development, as estimated by the efficiency of learning and transfer in assisted contexts. Subjects were 8- to ll-year-old children. Theoretical and clinical implications are discussed. (HOD)

Examined the relative role of parent-child relationships, family stress, and disease factors in predicting behavior problems in children with epilepsy. Found that children's self-reliance correlated with parent-reported behavior problems, whereas expression of affect related to teacher-reported problems. Overall, parent-child relationship factors…

Study of a cohort of low birth weight, preterm infants examined effects of maternal knowledge and concepts of child rearing on the home environment and developmental outcomes. Maternal knowledge, measured at 1 year, was found to be associated with quality of the home environment, the number of child behavior problems, and to a small degree, infant…
