David C. Geary

David Cyril Geary (born June 7, 1957, in Providence, Rhode Island) is an American cognitive developmental and evolutionary psychologist with interests in mathematical learning and sex differences.

His initial interests were in hemispheric laterality and associated sex differences, but focused his dissertation work on mathematical cognition under the direction of Keith Widaman (now at UC, Davis).

[2] Geary's wide-ranging interests are reflected in invited addresses in a variety of departments (anthropology, biology, behavior genetics, computer science, education, government, mathematics, neuroscience, physics, and psychology) and Universities throughout the United States, as well as in Canada, Europe, and East Asia.

Geary's research on mathematics learning, evolutionary psychology, and sex differences has been featured in many popular press outlets, including Discover,[3] Education Week,[4] Forbes,[5] CBS News,[6] and MSNBC[7] among many others.

Geary's research interests are centered on his four books, Children's mathematical development (1994), Male, female (1998, 2010, second edition), Origin of mind (2005), and Evolution of vulnerability (2015); the latter was discussed in an interview with the Guardian.

[17] Geary's research in evolutionary psychology also ranges across a variety of issues, from evolution of the hominid brain[18] to men's hormonal responses while competing against members of their in-group or against an out-group.
