Abstract
Abstract Human memory can be assessed with two types of tests: 1) recognition tests, in which subjects judge whether a current stimulus occurred previously, and 2) recall tests, in which subjects reproduce a previous stimulus in its absence. In contrast, there is a lack of comparable recall tests in nonhuman animals. Here, we describe the development of a touchscreen-based, shape reproduction task for rhesus monkeys that is similar to recall tests in humans. At study, monkeys saw a simple shape composed of two colored boxes located on a 5x5 grid. At test, one of the two boxes appeared in a new grid location. Monkeys earned food for reproducing the studied stimulus by touching the appropriate grid location for the second box. Performance was significantly above chance levels. In comparison with a recognition test matched for chance rate, monkeys showed similar accuracy and response latency for the two tests. This contrasts with human recall tests, which are normally harder than recognition tests. Possible reasons for this discrepancy are addressed and a new recognition test is proposed.
