Abstract

The purpose for the present study was to examine working memory for what, where, and when information in rhesus monkeys (Macaca mulatta) and adult humans using a computerized task. In Experiment 1, monkeys and humans completed three delayed matching-to-sample (DMTS) tasks: 1) identity DMTS, 2) spatial DMTS, and 3) temporal DMTS. In Experiments 2, the identity and spatial tasks were combined so that monkeys had to report both what and where information about an event. In Experiment 3, the identity, spatial, and temporal tasks were combined in order to examine what-where-when memory integration. In Experiment 4, monkeys and humans were presented with two sequential events, and a memory cue indicated which event they were required to report. The rhesus monkeys and human participants were able to report all three components of the events and there was some evidence suggesting that these components were integrated in memory for the rhesus monkeys.
