An Interdiciplinary Seminar of the Computer Science Department and the Learning Research and Development Center UNIVERSITY OF PITTSBURGH AN INFORMATION PROCESSING ARCHITECTURE TO EXPLAIN INSIGHT IN HUMAN PROBLEM SOLVING STELLAN OHLSSON 10:00 AM TO 11:00, FRIDAY, JANUARY 9TH, 1987 LRDC AUDITORIUM, SECOND FLOOR REFRESHMENTS FOLLOWING There are currently four models of symbolic computation which are in frequent use in Cognitive Science work: applicative programming, logic programming, rule-based programming, and object oriented (frame based) programming. Each of these exhibit some general properties of human information processing, but neglects others. For example, LISP contains a model for the hiearchical structure of action, which Production Systems do not. What is needed for the simulation of human cognition is a new architecture which exhibits all of the properties which we know are characteristic of human cognition, and which "has" them in a natural way. An attempt at defining such an architecture will be presented. It has grown within a specific simulation attempt, namely to understand formally what happens in so-called "Aha"-experiences, moments of insight during problem solving. A theory has been constructed which explains such events within the information processing theory of problem solving as heuristic search. The theory is then implemented within the architecture described. An example of a run of the system will be described. For more information, call Cathy Rupp 624-3950
