Mammals communicate often about a perceived change in the external environment, a predator, a prey or another conspecific, often signaling their emotional response: fear, anticipation, anger, social reward. For humans and other mammals, abilities to express these emotions and detect them in others and interpret them correctly, can be essential for wellbeing and survival. My laboratory studies how behaviors expressed in response to environmental changes communicate emotions and social understanding. For instance, we used cue-conditioned fear paradigms to discover empathy in juvenile mice: “an affective state more appropriate to the situation of another compared to one’s own.” Using conditioned place preference testing, we discovered that young mice derive pleasure from living with their adolescent peers.
Our experiments have also stepped outside the lab and into the field. 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. Natural life experiences are more relevant to healthy brain development and human experience. We study wildlife, and often ground squirrels because, like humans, they sense their environment predominantly through visual and auditory cues. We discovered that captive ‘asocial’ ground squirrels find rewarding assess 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. Through comparative studies across juvenile mammals, we have gained unique insights to social motivation and cognitive functions.
We also study how children respond to social situations. 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.
