Give a brief account on discrimination training.
Discrimination training entails rewarding a behavior (like as pecking) when one stimulus is present but not the others. One of the Bailey's chickens was given two note cards in the image on the left, one of which had a red circle and the other a blue circle. The peck on the red circle strengthened, but the peck on the blue circle did not (this process involves differential reinforcement). The fowl finally restricted its pecking to the red circle. The Baileys also demonstrated discrimination training with geometric figures using note cards with various shapes (such as circles vs. squares).
As long as the animal possesses the necessary sensory equipment, such as color vision, discrimination training is supposed to enable animals like chickens to "tell the difference" between forms (like rectangles or squares) or colors (like green or blue).
