In our newly renovated lab facilities, we conduct experiments with the local university and community populations to study the mechanisms underlying human cognition and behavior. Networked computers allow us to study interactions among participants, while screens provide anonymity. The lab is also outfitted to record audio samples (such as voice recordings), collect and store saliva samples for hormone and analysis, and with other tools to address a variety of research questions.
Our research emphasizes studying people from across cultures, and in particular, learning more about those living in non-WEIRD (Western, Educated, Industrialized, Rich, Democratic) societies. To that end, we frequently conduct research among the Hadza.
The Hadza are one of the few remaining populations of hunter-gatherers left in the world. They reside in a semi-arid region at the base of a branch of the East African rift valley close to Lake Eyasi. They number about 1,000, but only about 300 to 400 of them still forage full time. We have conducted a number of studies among the Hadza, studying topics such as social networks, cooperation, decision-making, and mate preferences.
