EPAM
EPAM is a psychological theory of learning and memory implemented as a computer program. Originally designed by Herbert A. Simon and Edward Feigenbaum to simulate phenomena in verbal learning, it has been later adapted to account for data on the psychology of expertise and concept formation. It was influential in formalizing the concept of a chunk. In EPAM, learning consists in the growth of a discrimination network.
EPAM was written in IPL/V.
