Developmental Psychology® publishes articles that significantly advance knowledge and theory about development across the lifespan. The journal focuses on seminal empirical contributions and occasionally publishes exceptionally strong scholarly reviews and theoretical or methodological articles. Studies of any aspect of psychological development are appropriate, as are studies of the biological, social, and cultural factors that affect development. The journal welcomes not only laboratory-based experimental studies but also studies employing other rigorous methodologies, such as ethnographies, field research, and secondary analyses of large data sets. We especially seek submissions in new areas of inquiry and submissions that will address contradictory findings or controversies in the field, as well as the generalizability of extant findings in new populations. Although most articles in this journal address human development, studies of other species are appropriate if they have important implications for human development. Submissions can consist of single manuscripts, proposed sections, or short reports.
