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? This book is based on an in-depth filmed conversation between Howard Burton and Barbara Fredrickson, Director Positive Emotions & Psychology Laboratory at UNC Chapel Hill. Topics covered by this extensive conversation include Barbara's 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.
