Mammals often communicate about perceived changes in their external environment: detection of a predator, a prey, or another conspecific and the signali their emotional response: fear, anticipation, anger, social anticipation. For humans and other mammals, these abilities: to express emotions, detect them in others, and interpret them correctly, can be essential for individual wellbeing and survival. My laboratory studies how behaviors expressed in response to environmental changes communicate emotions and social understanding. We used cue-conditioned fear paradigms to discover empathy in juvenile mice Using conditioned place preference testing, we discovered that young mice derive pleasure from living with their adolescent peers.

Our non-human mammal experiments arestepping outside the lab and into natural environments.  Laboratory animals are deprived of social refuge, freedom to explore novel objects and environments, and opportunities to make decisions that come with rewarding and aversive consequences. In nature, their wild and feral conspecifics experience the spatial and temporal complexity more relevant to healthy brain development and human experience. We study wildlife, often ground squirrels because, like humans, they sense their environment predominantly through visual and auditory cues. We discovered that captive ‘asocial’ juvenile ground squirrels derive pleasure from access to social living.  Through lab and field studies, we identified a putative ‘camaraderie effect,’ a proximal mechanism for altruism whereby helping others improves access to social rewards that in turn, promotes one’s own physiological health.

We also study how children and how they respond to social situations portrayed through stories. We use animated stories to learn where children pay attention while observing a dynamic social situation.  We ask how they respond emotionally to the trials and accomplishments of a story character, how they imitate, and how they comprehend stories.  We are particularly interested in how these social abilities develop with maturation. We ask how variations in behavioral and physiological responses to social situations, when measured objectively and at fine-scale, can be used to characterize individual differences in social temperament.
