A concise, reader-friendly introduction to an important but often under appreciated topic in modern psychology, Humor 101 explains the role of comedy, jokes, and wit in the sciences and discusses why they are so important to understand. Psychology professor Dr. Mitch Earleywine draws from his personal experiences in stand-up comedy to focus on how humour can regulate emotion, reduce anxiety and defuse tense situations, expose pretensions, build personal relationships, and much more. He irreverently debunks the pseudoscience on the topic of humour and leaves readers not only funnier, but better informed.
