Abstract: Twenty years ago, Allen Newell and Herbert Simon gave us a landmark book, Human Problem Solving, in which they introduced the method of protocol analysis, reported the parameters of human cognition, and set the stage for the emerging field of cognitive science. It is only fitting that, with his new book, Unified Theories of Cognition, Newell should set our course for the next twenty years. Once again he challenges us to shift paradigms, in this case to leave behind our focus on isolated cognitive tasks and to aim instead for the development of unified theories that account for the full range of cognitive function.
