A taxonomy of types of models of behavior is developed within the framework of statistical design concepts. The advantages and limitations of each are discussed. Components of variance from a previous study are derived for different models. It is shown that, with appropriate models, predictive proportions of variances are substantially greater than are ordinarily reported in behavioral research. The position is taken that attention to genetic variables in behavioral research can yield major increases in information gained for the development of behavior theory; that genetic environmental interaction is of major significance in behavior though generally ignored by both geneticists and psychologists; that variables apparently predictive only for a single genotype may provide clues to general behavioral predictors; and that fruitful interchange between geneticists and psychologists requires conceptual adjustments on both sides.
