Sarah Brosnan
Sarah Brosnan is a researcher studying the development of cognitive processes that underlie cooperation and reciprocity. The focus of her work has been on how animals perceive "exchanged goods and services," as demonstrated by reciprocal interactions. She has looked at both human and nonhuman primates as a way of understanding the evolution of cooperative and economic behaviors, specifically the topic of inequity aversion and the cooperative pulling paradigm. She works at Georgia State University in the Department of Psychology, and directs the university's Comparative Economics and Behavioral Studies Laboratory (CEBUS Lab).
