As our society ages, questions concerning the relations between generations gain importance. The quality of human relations depends on the quality of emotion communication, which is a significant part of our daily interactions. Emotion expressions serve not only to communicate how the expresser feels, but also to communicate intentions (whether to approach or retreat) and personality traits (such as dominance, trustworthiness, or friendliness) that influence our decisions regarding whether and how to interact with a person. Emotion Communication by the Aging Face and Body delineates how aging affects emotion communication and person perception by bringing together research across multiple disciplines. Scholars and graduate students in the psychology of aging, affective science, and social gerontology will benefit from this over-view and theoretical framework.

An evolutionary and cognitive account of the addictive mind candy that is humor. Some things are funny-jokes, puns, sitcoms, Charlie Chaplin, The Far Side, Malvolio with his yellow garters crossed-but why? Why does humor exist in the first place? Why do we spend so much of our time passing on amusing anecdotes, making wisecracks, watching The Simpsons? In Inside Jokes, Matthew Hurley, Daniel Dennett, and Reginald Adams offer an evolutionary and cognitive perspective. Humor, they propose, evolved out of a computational problem that arose when our long-ago ancestors were furnished with open-ended thinking. Mother Nature-aka natural selection-cannot just order the brain to find and fix all our time-pressured misleaps and near-misses. She has to bribe the brain with pleasure. So we find them funny. This wired-in source of pleasure has been tickled relentlessly by humorists over the centuries, and we have become addicted to the endogenous mind candy that is humor.
