One-, 5-, and 11-day-old rats in a cool environment (25 degrees C) acquired an operant response when rewarded with a 20-s-long warming of the platform (from 25 to 36 degrees C) on which they lay. In Experiment 1, the head-turning response was learned by pups at all ages. When the contingency was reversed so that pups were reinforced for turning to the side opposite that correct during training, the original response extinguished for 1-day-olds, but not for 5- or 11-day-olds. In Experiment 2… CONTINUE READING
