In this test, called the delayed nonmatching-to-sample task, food is available under the nonsample object during the test phase of each trial. The monkey is required to remember which object was presented as the sample and choose the other object to receive the food reward. This tests the monkey's ability to form and retain a memory of the presented object, and medial-temporal-lobe damage impairs performance on this task.
