Abstract
The ability of two nocturnal prosimians—greater galago and slow loris—to learn and to remember two-dimensional black-white pattern discriminations was investigated. There was no significant species difference. Both were found to be: sensitive to the number of visual cues available, able to benefit from repeated exposure to similar problems, capable of retaining previously learned material over a long period of time. Although they are individually quite variable in performance, these primitive primates are by no means untrainable on visual discrimination problems, as previous reports have suggested.
