ABSTRACT
One of the fringe benefits of writing a book is that one has the freedom of format to provide a chapter of self-evaluation. I will briefly state what I feel are the strengths of this book and of the ACT theory and then go on to a more extensive discussion of potential weaknesses. The principal contribution of this book, from my point of view, is that it offers a psychological theory of very broad generality. In this book it was applied, with moderate success, to many aspects of language, memory, inferential reasoning, and induction. It has obvious potential for extension to problem solving and indeed Greeno (1976) has done just that. It is an open question whether it can and whether it should be applied to issues of perception and imagery. With these possible and notable exceptions ACT seems capable of modeling all the tasks of concern to modern cognitive psychology.
