Rats can estimate their timing accuracy (IMAGE) CNRS Caption 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.
