Picture Memory (Pseudomatching) in the Rhesus Monkey

Abstract

Pseudomatching, the selection of the correct comparison stimulus without dependence on presentation of a sample stimulus, was demonstrated in monkeys being trained on a shock-avoidance, matching-to-sample task. Pseudomatching occurred whenever the problem sets were not fully counterbalanced for key position and correct symbol and seemed to represent memorization of specific stimulus configurations. Some animals showed the capacity to memorize hundreds of different 4-choice problems as revealed by test trials on which the samples were omitted.
