This revision of Cavanaugh's best-selling text is written within a biopsychosocial framework and covers the specific age-stages of adult development and aging. The book's currency of research and theories cited and the connections developed between research and application contribute to its excellent reputation. The book's focus on the gains and losses people experience across adulthood distinguishes it from its competitors. The new edition features a complete reworking of its organization and a thorough updating of citations, including hundreds from 1997 through the present. A new separate chapter on Social Cognition, Chapter 9 (the research area of the new co-author, Fredda Blanchard-Fields), offers expanded coverage of this exciting area.
