In a study on latent learning using rats and a maze, there were three groups of rats: group 1 wandered around without ever receiving a reward; group 2 was always rewarded at the end of the maze; and group 3 wandered for the first 10 days but was then rewarded for completing the maze on the eleventh day. The performance of group 3 demonstrated reductions in running time and declines in error rates, so cognitive theorists concluded that .

The performance of group 3 demonstrated reductions in running time and declines in error rates, so cognitive theorists concluded that rats who were allowed to roam around the maze, nevertheless learnt something. This was known as latent learning. A concept that refers to learning that is not demonstrated until they are motivated to do so.
