Monkeys (Macaca mulatta) rank lists using multiple cognitive mechanisms simultaneously.

ABSTRACT: Memorizing the relations between items and learning relational rules are two ways in which sets of items can be ranked. We investigated the interaction of these types of learning in a series of five experiments with six adult male rhesus monkeys. We presented monkeys with three types of image sets. Scene sets were random images of natural scenes or cityscapes with no perceptually evident pattern by which to rank them. Relations among these images had to be learned through trial and error. Patterned sets were shapes that varied systematically along a physical dimension such as size such that a single rule for ranking them could be applied across images. Disordered sets were the same as Patterned sets, but monkeys were trained to rank them in an arbitrary order that was not consistent with d
