Abstract
Two groups of rats were run in a straight alley. One group (NR) was given one nonreinforced trial and one reinforced trial. Another group was given two reinforced trials. Based on goal times, Group NR was more resistant to extinction. This finding supports previous work using a small number of acquisition trials.
