Review of "The Psychology of Human-Computer Interaction by Stuart K. Card, Thomas P. Moran and Alan Newell", Lawrence Erlbaum Associates, Hillsdale, NJ, 1983.

This is a book that is intended not just to be read but to be used-through discussion, study, and prolonged reflection. The major concern of the book is, as the title implies, how humans interact with computers. The authors construct an empirically based cognitive theory of a skilled human-computer interaction and apply it to the specific problem of text editing. They do not simply inform readers of the problems, they provide solutions to the problems and describe a methodology for unifying psychology and computer science. A few years ago Ben Shneiderman [1] listed the computer science topics relevant to human-factors research. <u>The Psychology of Human-Computer Interaction</u> tells the student how to actually perform human-factors research. It discusses the processes involved, the techniques to use, and the methods to follow.
