Behavioral Genetic Approaches to Psychophysiological Data

Behavioral genetic techniques have been developed to study the genetic and environmental contributions to individual differences in behavior, including covariances between different types of behaviors and stability of behaviors. Several studies have shown that certain psychophysiological characteristics appear to have heritable components. Therefore, it would seen appropriate that behavioral genetic techniques should be generalized for application to psychophysiological data. After reviewing general behavioral genetic methodology, this paper summarizes classical and new biometrical genetic techniques for both univariate and multivariate analyses, suggesting how these techniques are appropriate for the study of psychophysiological data and the relationship between psychophysiological variables and behavioral measures
