Research and Interests
Professor Davidson is an expert on the history and meta-theory of psychology, especially focusing on personality and methodology. His research includes histories of personality types, like the “ambivert,” as well as broader disciplinary and cultural histories of personality traits and psychometrics. Additionally, he is interested in and teaches quantitative methods and research practices. He is currently expanding his dissertation into historical/theoretical work on the dynamics of race and gender in personality and research psychology’s past and present.
