Abstract
Lower-class and middle-class English boys learned a size discrimination under four reinforcement conditions: (a) signal light, (b) candy, (c) “right, correct”, and (d) “good, fine”. The signal light and candy conditions required fewer trials to criterion than the verbal conditions. Neither social class nor the interaction between social class and reinforcers was significant.
