ABSTRACT
A person writes a research monograph such as this with the intention that it will be read. As a consumer of such monographs, I know it is not an easy decision to invest the time in reading and understanding one. Therefore, it is important to be up front about what this book has to offer. In a few words, this book describes a new methodology for doing research in cognitive psychology and applies it to produce some important developments. The new methodology is important, because it offers the promise of rapid progress on some of the agenda of cognitive psychology. This methodology concentrates on the adaptive character of cognition, in contrast to the typical emphasis on the mechanisms underlying cognition.
