Abstract
PAS-II, a computer program which represents a generalized version of an automatic protocol system (PAS-I) is described. PAS-II is a task-free, interactive, modular data analysis system for inferring the information processes used by a human from his verbal behavior while solving a problem. The output of the program is a Problem Behavior Graph: a description of the subject's changing knowledge state during problem solving. As an example of system operation the PAS-II analysis of a short cryptarithmetic protocol is presented.Keywords
