SUMMARY:Arnon Lotem\, Visiting Professor UCLA\, Title: Evolution of diverse (and advanced) cognitive abilities through adaptive fine-tuning of learning and chunking mechanisms
DESCRIPTION:Understanding the evolution of advanced cognition requires explaining how it could have gradually evolved through selection acting on heritable variations in simpler cognitive mechanisms. Making use of a previously proposed theory\, I will explain how the evolution of cognitive abilities can be captured by the fine-tuning of basic learning and chunking mechanisms. Specifically\, I will demonstrate how the process by which elements are combined into chunks and associated with other chunks\, or elements\, may be critical for what the brain can do\, and that it must be fine-tuned to ecological conditions in order to produce adaptive behaviors.

SUMMARY:Kristopher Smith\, Washington State University\, Title: Long-distance friends and collective action in fisheries management
DESCRIPTION:The management of shared natural resources often hinges on local cooperation\, yet the social networks linking communities across space can both complicate and enable collective action. This talk examines how long-distance friendships—relationships that bridge community boundaries—shape trust\, cooperation\, and participation in fisheries management in coastal Tanzania. Drawing on theoretical models and multi-site ethnographic and survey data from the Tanga Sociality and Fisheries Project\, I show that long-distance friendships provide key forms of material support similar to local friendships\, suggesting they are a resilient social strategy for managing ecological and economic risk while fostering interdependence across villages. In turn\, people with more long-distance friends express greater trust in non-local partners and are more likely to engage in collective monitoring and reporting of destructive fishing practices. Finally\, I introduce a new measure\, “long-distance orientation\,” capturing individual variation in the motivation and capacity to form and sustain these ties\, highlighting psychological and structural factors that facilitate cooperation at a distance. Together\, these findings suggest that long-distance relationships can serve as a foundation for scaling up collective action and designing management systems that bridge community boundaries.
