Rats were taught to press a lever for at least 3.2 seconds. Depending on the gap between this task and its achievement, a reward was distributed, on the left or right side. Rats mostly chose the feeder corresponding to their margin of error, as they learned that the reward location depends on their accuracy and were able to evaluate their performance.

PNAS - Thanks to their capacity for introspection, human beings are able to estimate the duration of their actions. When they perform a task - especially a time-based task - they can evaluate their performance and correct themselves in order to do better next time. This ability is not exclusive to the human species: new research has just demonstrated for the first time that the rat can also do so! These results were obtained in a joint study undertaken by researchers from the Institut des neurosciences Paris-Saclay (CNRS/Université Paris-Saclay), Neurospin (CEA) and a researcher from the Institute of Psychology of the Polish Academy of Sciences.
