EPAM (Elementary Perceiver and Memorizer) - an early computer model of rote learning by the method of paired associates, first conceived by Herbert Simon and Allen Newell during their early conception about computer simulation of cognitive processes in the 50s , implemented as computer program by Edward Feigenbaum in the late 50s in IPL-V for the IBM 704 and IBM 7090, as topic of his Ph.D. thesis at Carnegie Mellon University. In terms of psychology and behaviorism EPAM associates responses with external stimuli, quite similar to classical conditioning.
