These essays by some of the most prominent figures in linguistics, artificial intelligence, and psychology explore the problems involved in creating a general cognitive science that will treat language, thought, and behavior in an integrated fashion. They address the fundamental questions of the relations between linguistic structures and cognitive processes, between cognitive processes and language behavior, and between language behavior and linguistic structure.
