takes seriously the idea that design research warrants development in the cognitive sciences, and Visser lays the groundwork for the integration of design research and cognitive science. This seemingly simple framework — designing is the construction of representations — has implications that set the stage for this mutually beneficial integration. This volume will be of great interest to scholars concerned with design — not only in cognitive design studies, but also in design methodology and engineering — as well as cognitive scientists who are interested in problem solving in 'the real world.' Cognitive ergonomists and design practitioners will also be richly rewarded by a close reading of this volume.
