Sarah Brosnan is a researcher into the development of the cognitive processes that underlie cooperation and reciprocity. The focus of her work has been on animals' perceptions, as demonstrated in reciprocal interactions, of the value of "exchanged" "goods and services". She has looked at both human and nonhuman primates as a way of understanding the evolution of cooperative and economic. She works at Georgia State University in their Department of Psychology and directs their Comparative Economics and Behavioral Studies Laboratory (CEBUS Lab).
