BRIEF NOTES ON THE EPAM THEORY OF
VERBAL LEARNING E. A. Feigenbaum and
H. A. Simon UNIVERSITY OF CALIFORNIA, BERKELEY, AND CARNEGIE INSTITUTE
OF TECHNOLOGYWe have been asked briefly to sketch the EPAM (Elementary Perceiver and Memorizer) model. If these notes are overly succinct, clarification will be found in the references.Model and Method. EPAM is a theory of the information-processing
activity underlying verbal learning behavior. The precise formulation
of the model is given in an information-processing language for a computer. The computer is then used as a tool for generating the remote
consequences of the information-processing postulates in particular experimental conditions. EPAM is a closed model in the sense that it can
be treated as a subject in learning experiments. The experiments are
not run "live" but are simulated using programs to simulate an experimenter, the apparatus, and the stimulus environment. Such simulated
experiments yield a stream of verbal behavior from EPAM fully
equivalent in nature to the "raw data" which an experimenter takes from
his subject in a live experiment. Of course, the degree to which this behavior looks like human behavior in the same experiments is the fundamental question of model validation.EPAM I. EPAM contains a set of "macroprocesses" which deal with
the organization of the total learning task, and a set of "microprocesses"
which learn the individual items. (The macroprocesses are referred to as
EPAM I, the complete model as EPAM II.) That such a factorization of
the learning activity is useful and valid is argued in another place
( Feigenbaum and
Simon, 1962).The fundamental assumptions of EPAM I are as follows:
|1. ||Any given stimulus item requires a definite amount of processing
time before it is learned. For items of the same average difficulty, this
time is relatively constant. Thus, the total time to learn n items is given
approximately by Tn = Kn. (It is postulated that time, rather than
number of exposures per se, is the critical variable.)|
