Ralph Adolphs, Caltech’s Bren Professor of Psychology, Neuroscience, and Biology, usually conducts research on human volunteers at the Caltech Brain Imaging Center (which he also directs) to try to understand how the fundamental biology of the brain, as revealed through neural activity, produces the breadth of human feelings, abilities, and these social behaviors. But now, amid months of stay-at-home orders that have kept human subjects off campus and out of his lab, Adolphs has teamed up with several colleagues to craft a long-term internet-based study that examines how the COVID-19 pandemic has influenced people’s emotions, attitudes, and biases.
