This well-established and accessible text has been completely revised in this expanded edition. Each chapter has been updated, often extensively, to reflect current thinking, and an important new chapter on death, dying, and bereavement has been added. Providing a comprehensive overview of the psychological process of aging, the text examines what constitutes older age and presents the latest theory and research in various domains, including aging and memory; aging and language; aging, personality and lifestyle; and mental illness and aging. Consideration is given to the problems inherent in measuring the psychological status of older people, and the author looks at how we will define being old in the future. This new edition is essential reading for all those working or training to work with older people and is a key text for students in this field.
