Delayed match-to-sample with multiple, potentially repeating distractors.

A sample stimulus is shown during the sample period. The stimulus is characterized by a one-dimensional variable, such as its orientation between 0 and 360 degree. After a delay period, the first test stimulus is shown. The agent needs to determine whether the sample and this test stimuli are equal. If so, it needs to produce the match response. If the first test is not equal to the sample stimulus, another delay period and then a second test stimulus follow, and so on.
