Instructions and Reinforcement in the Modification of a Conversion Reaction
The effects of two variables, instructions and social reinforcement, were examined sequentially in a case of a conversion reaction. Reinforcement in the form of praise resulted in an increase in S's ability to walk. When reinforcement was removed, other variables including instructions, expectancy, social reinforcement from other patients, and self-reinforcement may have contributed to unexpected improvements in walking. However, reinstitution of reinforcement led to the most dramatic increases in walking.
