Within human problem-solving, the propensity to use a familiar approach, rather than switch to a more efficient alternative is pervasive. This susceptibility to “cognitive set” prevents optimization by biasing response patterns toward known solutions...

Across diverse societies, task assignment is a socialization practice that gradually builds children's instrumental skills and integrates them into the flow of daily activities in their community. However, psychosocial tensions can arise when coopera... Read More about Socialization, Autonomy, and Cooperation: Insights from Task Assignment Among the Egalitarian BaYaka.

Humans are rare among mammals in exhibiting paternal care and the capacity for broad hyper-cooperation, which were likely critical to the evolutionary emergence of human life history. In humans and other species, testosterone is often a mediator of l... Read More about Sharing and caring: Testosterone, fathering, and generosity among BaYaka foragers of the Congo Basin.

Where innovations flourish: an ethnographic and archaeological overview of hunter–gatherer learning contexts (2020)
Journal Article

Research in developmental psychology suggests that children are poor tool innovators. However, such research often overlooks the ways in which children's social and physical environments may lead to cross-cultural variation in their opportunities and...
