The seesaw. (a) Seesaw closed. The lid covers the food box, i.e. food rewards cannot be accessed. (b) Seesaw opened. By sitting on the platform, the rat lowers the platform and raises the lid, i.e. food rewards are accessible. (c) The seesaw’s platform, food box and base seen from above. (d) The seesaw’s platform before it connects with the electromagnet and microswitches located under it. When the position of the seesaw was changed by moving the seesaw to a different location inside the enclosures to account for local enhancement, the platform and food box’s positions were inversed.
