Abstract
33 rats were given 10 trials in crossing a narrow elevated path from one platform to another to receive food. They were then divided into 2 groups one of which spent time before and between extinction trials on the goal platform, the other on a neutral platform. Both groups were extinguished to a criterion. The goal platform group reached the criterion in a mean of 3.12 trials, group C in 8.25. There were also differences in crossing and latent times on extinction trial one. It is noted that "the learning that underlies extinction may serve not merely to subtract the incentive but to produce an 'emotional' interference with the response."
