<b>A longtailed macaque performing in an Inhibitory Control trial.</b> In the Inhibitory Control task, rewards were placed under the two outer cups of 3 cups, while the subject was watching. The middle cup remained empty and untouched. If the subject first chose one of the outer cups it was allowed to make a second choice. If, however, it chose the middle cup first, no further choices were possible. A correct response was scored when the monkey chose the two outer cups in succession while skipping the middle cup (as illustrated here in this video).
