Mental Models is a book published by Lawrence Erlbaum Associates, Inc., in 1983 . It was edited by Dedre Gentner and Albert L. Stevens, both employees of Bolt, Beranek and Newman, Inc. at the time. It appeared at about the same time as a book by the same name by Philip Johnson-Laird. According to the acknowledgment of the book, it resulted from a workshop on mental models held at the University of California, San Diego in October 1980, that was jointly sponsored by the Office of Naval Research and the Sloan Foundation. Chapters Some Observations on Mental Models — Donald A. Norman, UCSD Dr. Norman describes the properties of mental models — that they can be contradictory, incomplete, superstitious, erroneous, and unstable, varying in time. So the job of system designers is to help users form an accurate and useful mental model of a system. And the job of researchers is to set up experiments to learn to understand actual mental models, even though they may be messy and incomplete.
