Dr. Nicholas A Christakis's lab at Yale University focuses on understanding how individuals perceive their social connections in communities, specifically in rural Honduras. The research explores cognitive social maps, which are mental representations of social networks, and how these perceptions impact social and health-related behaviors. The lab's work sheds light on the relationship between cognitive social networks and well-being, particularly in the context of aging and social isolation.
