What are the fundamental mechanisms of decision making, processing speed, memory and cognitive control? How do these give rise to individual differences, and how do they change as people age? How are these mechanisms implemented in neural unctions, in particular the functions of the frontal lobe? How do they relate to the demands of everyday, 'real life' behaviour? Over almost five decades, Pat Rabbitt has been among the most distinguished of British cognitive psychologists. His work has been widely influential in theories of mental speed, cognitive control and aging, influencing research in experimental psychology, neuropsychology and individual differences. This volume, dedicated to Pat Rabbitt, brings together a distinguished group of 16 contributors actively pursuing research in the fields of speed, memory, and control, and the application of these fields to individual differences and aging. With the latest work from senior figures in the field, and a focus on fundamental topics in both teaching and research, the book will be valuable to students and scientists in experimental psychology and cognitive neuroscience.
