Models of Cognitive Aging

We live in an ageing society, where people are living longer, and where decreases in the birth rate mean that the proportion of the population above retirement age is steadily increasing. An ageing population has considerable implications for health services and care provision. Consequentlythere is a growing interest among researchers, medical practitioners, and policy makers in older adults, their capabilities, and the changes in their cognitive functioning. This book offers an up-to-the-minute account of the latest methodological and theoretical issues in cognitive ageing. Part ofthe Debates in Psychology series, it sets out the arguments surrounding the currently controversial questions in cognitive ageing. What is the appropriate methodology for understanding cognitive change? How many factors are necessary to understand the patterns of age-related change? What might thesefactors be? The topics and arguments are explored in a series of chapters by the leading researchers in the field. Each contributor offers their view of how cognitive ageing can be best understood, and together they cover a broad range of cognitive functions including language use, cognitiveslowing, and memory loss.
