[Reliability, heritability, correlation in longitudinal studies (author's transl)].

Abstract

An analogy exists between the mathematical models of psychological test theory and quantitative genetics, as well as between the parameters, reliability and heritability, derived from these models. With the same results, heritability and correlation in longitudinal studies are only different approaches to the same problem, the reliability of measurement in the long run, that is of fundamental consequence for personnel selection.
