Four groups of twenty Ss each were conditioned for an abnormal response of the Muller-Lyer illusion. The four groups were:1. Control - no response from E2. Positive reinforcement - "mmm-hmm" when parison was longer than the standard3. Punishment - "huh-uh" when the comparison was shorter than the standard.4. Both punishment and positive reinforcement - "mmm-hmm" when the comparison was longer than the standard and "huh-uh" when the comparison was shorter than the standardThere was no difference in sex, or in tests before and after verbalization of the reinforcement contingency by each S. There was an overall difference as measured by an analysis of variance (p < •001) . There was no significant difference between positive reinforcement and the control group. There was a significant difference between Groups 1 and 3, and Groups 1 and 4. There was no significant difference in Groups 3 and 4 although there was a trend in that direction.
