Dealing with the theme of "prospects for artificial inteligence as the general science of intelligence", this work covers a wide range of topics. It attempts to identify trends and projects into the future, instead of simply surveying past achievements. The editor first introduces attempts to define the design-based approach to the study of intelligence, that characterizes IA. Following this, contributing papers report on work already done. Thus the subjects discussed include natural language, evolutionary AI, robotics, game playing, tutoring systems, cognitive modelling, SOAR, neural nets, and the modelling of motivation and emotions.
