[Forwarded from the Stanford bboard by Laws@SRI-AI.] M. Pavel & D. Sleeman _____________________________________________________ S.P.A - SEMINAR IN PROTOCOL ANALYSIS ______________________________________________________ Introduction to protocol analysis: an example from developmental psychology. Jean Gascon Stuart Card Xerox Palo Alto Research Center The first of this series of seminars on protocol analysis will be structured as a tutorial on protocol analysis and comput- er simulation. Stuart Card will give a brief overview of the history, motivation and practice of the methodology. Jean Gascon will then illustrate, with a simple example, how protocol analysis is performed. The application area will come from developmental psychology. First, protocols of children of vari- ous ages performing one of Piaget's "seriation" task will be shown. We will then explain how one goes from the actual data to the construction of the "problem space" (a la Newell and Simon). The next step consists of regrouping the problem spaces of dif- ferent subjects into a more general psychological model (dubbed BG in this particular case). We will see how the BG language fa- cilitates the writing of simulation models. A computer program that does automatic protocol analysis of the seriation protocols will then be introduced. This program provides some additional insights about the process of protocol analysis itself. In the conclusion we will discuss the advantages and inconveniences of protocol analysis relative to the other methodologies available in cognitive psycholgy. _____________________________________________________ Place: Jordan Hall, Room 100 Time: 1:00 pm, Wednesday April 11, 1984 _____________________________________________________
