Errorless Discrimination Learning in the Pigeon: Effects of Chlorpromazine and Imipramine

H. S. Terrace 1

1 Department of Psychology, Columbia University, New York

Chlorpromazine or imipramine disrupts a pigeon's performance on a discrimination between a vertical and horizontal line only if the discrimination was learned with errors. Errorless learning is obtained if training starts with an easy-to-learn discrimination of color and shifts progressively to the more difficult horizontal-vertical discrimination.
