FIGURE 5.6 Latent Learning Beginning with day 1, the rats in group 1 received a food reward at the end of the maze, and the number of errors they made steadily decreased each day. The rats in group 2 never received a food reward; they made many errors as they wandered about in the maze. The rats in group 3 did not receive a food reward on days 1 through 10. Beginning on day 11, they received a food reward at the end of the maze. Notice the sharp decrease in errors on day 12 and thereafter. According to Tolman, the rats in group 3 had formed a cognitive MAP of the maze during the first 11 days of the experiment. Learning had taken place, but this learning was not demonstrated until reinforcement was present—a phenomenon that Tolman called latent learning.
