In the initial 2019 study, rats were taught to steer a car made from a plastic cereal container by grasping wires that propelled the vehicle forward. The rodents quickly mastered the skill, steering with surprising precision to reach a piece of Froot Loop cereal as a reward.
Building on these findings, the researchers developed improved "rat-operated vehicles" equipped with rat-proof wiring, durable tires, and ergonomic driving levers. They observed that the rats showed intense motivation during training sessions, often jumping into the car and initiating the driving mechanism before the vehicle began moving.
Professor Lambert noted that the driving-trained rats eagerly approached the side of their cage during testing times, similar to how a dog might react when anticipating a walk. This behavior led the team to question whether the rats were motivated solely by the food reward or if they found the driving experience itself rewarding.
Surprisingly, two out of the three rats chose to drive, suggesting they derived pleasure from both the journey and the destination. Physical signs of positive anticipation were also observed.
