Mental Darwinism, a new approach to the study of mental phenomena, applies selectionist ideas to problems of mind and behavior. McNamara challenges the instructivist view that memories occur when information from the environment is transferred into the mind. Current experimental evidence confirms the insights of two turn-of-the-century philosophers, William James and Henri Bergson, who originally proposed applying Darwinian principles to mental processes. The view of the mind that emerges from this approach helps us understand why memory evolves as it does and is not always accurate or veridical, how memory is related to personal identity, and how a large number of neuropsychological disorders develop.

We've nearly all been there--awakened with a pounding heart by frightening scenes that seem real, but were conjured up and existed only in the sleeping mind. Nightmares affect people across countries and cultures, with some 10 percent of the world's population reporting recurrent nightmares. Parents have reported, and science has recorded, nightmares in children as young as 18 months. Up to 40 percent of children aged 2 to 12 experience nightmares, as do some 35 percent of veterans and 50 percent of adults with chronic illness. With this book, a psychologist widely known in his field shows how nightmares evolved and were useful to ancestral populations, and why nightmares may carry beneficial functional effects even today for people who suffer from the pulse-pumping dreams. McNamara brings us up to date on the biology of a nightmare and what, specifically, happens in the brain during the event. He also explains the history and development of nightmares and likely causes, including traumatic events, psychological and physical disorders, and commonly consumed medications. Many examples of nightmares are presented and explained. The content of nightmares is given unusually detailed attention, and the latest science on nightmares is succinctly reviewed. Tables in every chapter summarize existing findings and conclusions on nightmares, and strategies for dealing with nightmares are described. In this novel view, McNamara shows why, rather than being harmful, nightmares can be a helpful adaptive system. The special theme of "spirit possession," which frequently occurs in nightmares, is discussed and related to similar themes in horror movies and horror fiction.

With a breadth including breaking research from around the world, this set created by a team of experts is the most authoritative source that exists regarding the biology and psychology of dreaming. Readers will not only understand the new science of dreams, but how that science could lead to innovations in the medical, social technical and biotech fields. Although it has been described since ancient times, dreaming remains a somewhat mysterious mental process, and scientists around the world continue to study its mechanisms and meanings. In this unique set of books, experts in the field from around the globe gather to show the newest and most exciting research and findings related to the biology and psychology of dreaming. New studies of dream content, for example, show that across age groups, cultures and clinical groups, dreams have recurring themes. New brain imaging techniques show us specific brain regions involved in dreaming. Other research featured here describes the biology or psychology of realistic and bizarre dreams, of symbolic images in dreams, and of how differences in gender and personality affect dreams and dreaming. The newest and most extensive source of information on dreaming in existence, this set gives readers insights into how this new science could lead to innovations in the medical, social, technical, and biotech fields. Dozens of contributors—some top experts in their fields known internationally—show us how brain functions affect and are affected by dreaming and why these new findings should be important to all of us. Volume I spotlights the biology of sleep and dreaming. Volume II focuses on dream content and its many facets. In Volume III, the many theoretical accounts of dreams are presented.
