Barbara Fredrickson

The Science of Emotions is based on an in-depth filmed conversation between Howard Burton and Barbara Fredrickson, Director Positive Emotions & Psychology Laboratory at UNC Chapel Hill. Why do we smile, laugh and actively seek out personal connections with the people around us? Why does it feel good and what evolutionary purposes do our so-called “positive emotions” serve?

Topics covered by this extensive conversation include Barbara’s groundbreaking work on the science of positive emotions, including her broaden-and-build theory, the undoing effect and upward spirals, while highlighting relevant evolutionary-driven hypotheses together with measurement details of empirical studies.
