Daniel J. Bauer, winner of the Award for Distinguished Scientific Early Career Contributions to Psychology, is cited for the creative integration of sophisticated quantitative methods with empirical research in the psychological sciences. Bauer draws on his joint training as a developmental and quantitative psychologist to pursue the design, evaluation, and application of novel statistical models for the study of individual and group differences in stability and change over time. A key goal underlying his work is maximizing the correspondence between the theoretical model under study and the statistical model used to empirically evaluate the scientific hypotheses. In addition to the citation, a biography and selected bibliography of Bauer's publications are provided.
