Abstract

Separate groups of mice received 25 training trials in a shock‐escape T‐maze at 7,9,11, or 13 days of age, followed by retention trials 24 hr later. During original training, all mice were trained to the goal opposite their 1st‐trial choice‐point turn. During the retraining sessions, half of the mice in each age group received an additional 25 trials to the same goal as original training, while the other half was trained to the goal opposite that of original training. All age groups demonstrated improved performance during training in reaching the choice point, although only mice 9 days of age and older indicated an increase in correct choice‐point turns. During retraining, only the groups trained at 11 and 13 days of age showed significant effects of prior training.
