Abstract
Nine stumptail monkeys (Macaca speciosa) were trained on a successive discrimination learning set where each 2-choice problem was in the paradigm: AA, go Left—BB, go Right. Each S was given 5 unique 8-trial problems a day for 150 days. For half of the animals, the A and B objects did not differ in color; for the other half, color cues were always present and relevant. Significant inter-problem learning was found, but improvement with practice was very slow. The group of monkeys which could use color as a cue did not form the learning set any more efficiently than the group forced to rely on cues other than color.Keywords
