Developmental Psychobiology: A look back on 30 years

Developmental Psychobiology publishes papers from the disciplines of psycho logy, biology, neuroscience, and medicine that contribute to an understandi ng of behavioral development. Research focuses on development in the embryo /fetus, neonate, juvenile, and adult as well as multidisciplinary research that relates behavioral development to anatomy physiology, biochemistry gen etics, and evolution. The journal represents a broad phylogenetic perspecti ve on behavioral development by including studies on invertebrates, fish, b irds, non-human primates, and humans. This paper presents an analysis of em pirical articles published since its first issue in 1968. This analysis cov ers number of authors, sex of first author evidence of grant support, and p articipation of investigators from outside the US. Additionally, the analys is includes the topic of research, level of analysis, and subject of experi mental study. Over its 32-year history, Developmental Psychobiology has pub lished papers on a wide range of topics representing a broad phylogenetic p erspective, with a continued focus on behavioral investigation. This analys is revealed trends such as an increase in the number of studies at a physio logy/anatomy level, an increase in studies with human subjects, and increas es in contributions from investigators outside of the United States as well as women.
