Figure 1

Schematic drawing of a testing session trial. This shows a mutual side trial in which the subject would have to move to the other side (high inhibitory demands) to reorient the seesaw. If the subject directly releases the food, it will end up in the location that is mutually accessible to the subject and dominant conspecific (left green area). Delivering the reward to the solo location (right green area) requires the subject to first move to the opposite room without pulling the release rope, reorient the seesaw to the right by pulling the rope attached to the right side of the seesaw (1), move back into the tunnel to now pull the food release rope (2), and subsequently collect the food from the solo food location (3).
