Cognitive tests. In the DR task, animals were shown a red square on either the left or right side of a touch screen in the stimulus presentation phase (a) and, after a delay, were required to select the square on the same side during the query phase (b). In the DMS task, monkeys were shown a picture at the center of a touch screen in the stimulus presentation phase (c) and, after a delay, were required to select the previously shown image in the query phase (d). Correct responses resulted in a small palatable food reward.
