These papers, with the editors' introductions, aim to illustrate the many ideas, the range of theories, methods and approaches, and the fruits of the cognitive revolution. They are divided into sections on: foundations; learning, memory and cognition; and communications, speech and language.

This book constitutes the refereed proceedings of the Third Australian Conference on Artificial Life, ACAL 2007, held in Gold Coast, Australia, in December 2007.

The 34 revised full papers presented were carefully reviewed and selected from 70 submissions. Research in Alife covers the main areas of biological behaviour as a metaphor for computational models, computational models that reproduce/duplicate a biological behaviour, and computational models to solve biological problems. Thus, Alife features analyses and understanding of life and nature and helps modeling biological systems or solving biological problems. The papers are organized in topical sections on heuristics, complex systems, evolution, biological systems, and networks.

The papers in this collection, and the editors' introductions, illustrate the ferment of ideas, the wide range of theories, methods and approaches, and the rich fruits of the cognitive revolution. Written in clear and accessible language, this is an essential text for courses in Cognitive Science.
