The trial-unique delayed nonmatch to sample task is commonly used to test recognition memory in animals. In this task, the subject is presented with a sample stimulus and then, after a delay, is presented with two stimuli, one of which is identical to the sample and the other is novel. The subject's response to the novel stimulus is taken as an index of recognition memory. This task is useful for testing recognition memory in a single exposure to a novel stimulus.
