Progress in the Developmental Genetic Analysis of Behavior
Near the end of his illustrious career, Gottlieb lamented the continued dominance of heritability analysis in human psychology and the difficulties in winning support for the developmental point of view. Recent, spectacular progress in molecular genetic neuroscience and the genetic study of behavior, however, is rendering heritability analysis passé. In many recent articles that mention “heritability,” the term is employed in the generic sense of…
Analysis of Variance in the Service of Interactionism
Vreeke (this issue) asserts: "If you hold that reality is interactive, but use methods which presuppose the separateness of genes and the environment, your are stuck with a problem of interpretation." A similar point was made recently by a colleague in behavior genetics who chastised me, a critic of heritability analysis [Wahlsten, 1990, 1994, 1999a, 1999b], for employing the analysis of variance (ANOVA) in a recent study [Crabbe, Wahlsten and Du…

Sample size to detect a planned contrast and a one degree-of-freedom interaction effect
A simple method is described for estimating the sample size per group required for specified power to detect a linear contrast among J group means.This allows comparison of sample sizes to detect main effects with those needed to detect several realistic kinds of interaction in 2 × 2 and 2 × 2 × 2 designs with a fixed-effects model.For example, when 2 factors are multiplicative, the sample size required to detect the presence of nonadditivity is …
