Connectionism is a way of modelling how the brain uses streams of sensory inputs to understand the world and produce behaviour, based on cognitive processes which actually occur. This book describes the principles, and their application to explaining how the brain produces speech, forms memories and recognises faces, how intellect develops, and how it deteriorates after brain damage. Part I explores the basic concepts, the architecture and properties of the most common connectionist models, and how connectionist learning rules work. Part II describes and evaluates connectionist models of a variety of cognitive processes, including the learning and production of speech, the formation of episodic memories and visual representations, the development of cognitive processes in infancy, and their breakdown in brain-damaged patients. The models range from some well-known classics to others at the frontiers of current research. Each chapter ends with a list of recommended further reading. Also included is a disk with the software for running tlearn, a user-friendly simulator for connectionist modelling of cognitive processes, which will run on either PCs or Macs. The software includes exercises to introduce the simulator, and working copies to explore some of the models described in the text. A reference handbook for tlearn is included to enable readers to build their own models. The authors, as well as being leading researchers in their field, have extensive experience of teaching connectionism to undergraduates. They have written the first comprehensive, up-to-date textbook on connectionist modelling, designed specifically for advanced undergraduates, and accessible to those with only limited knowledge of mathematics. This will be an essential introductory text for all students in psychology or cognitive science taking a course on connectionism.

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.
