ABSTRACT
Over the past 5 years my colleagues and I have been developing a computer program to teach medical diagnosis. Our research synthesizes and extends results in artificial intelligence (AI), medicine, and cognitive psychology. This chapter describes the progression of the research, and explains how theories from these fields are combined in a computational model. The general problem has been to develop an “intelligent tutoring system” by adapting the MYCIN “expert system.” 1 This conversion requires a deeper understanding of the nature of expertise and explanation than originally required for developing MYCIN, and a concomitant shift in perspective from simple performance goals to attaining psychological validity in the program’s reasoning process.
