The Elements of Cognitive Aging provides a qualitative overview (mostly using graphical meta-analysis) of the vast literature on aging and speeded tasks-bringing together, for the first time, almost everything we know about aging and processing speed. The book investigates age-related slowing in elementary tasks (including updated parameters for the Aging Human Information Processor) and tasks of executive control (inhibition, task shifting, and task coordination). It examinesregularities in the age-related effects of these tasks that might hint at underlying brain-related mechanisms, while having a keen eye for alternative explanations (such as increased caution with age). It models the course of speed-of-processing over the lifespan and investigates the influence ofgenerational differences on mental speed. Finally, it examines the influence of age-related mental slowing on other aspects of cognition (working memory, executive control episodic memory, aspects of fluid intelligence), and provides the first systematic review of age-speed-cognition mediation in a longitudinal context.
