Commitment to social deprivation and verbal conditioning

Control Ss who experienced high prior deprivation of a reinforcing stimulus (approval) responded more with a reinforced response in a verbal conditioning situation than Ss less deprived. Other Ss committed themselves to undergoing postexperimental deprivation of social reinforcement after the same high prior social deprivation. A model suggested by dissonance theory predicted that such Ss who committed themselves for lower rewards would experience greater dissonance; the greater the dissonance, the more could Ss justify their decisions and reduce dissonance by reducing their motive for social reinforcement, consequently behaving in the conditioning situation as Ss who had low motivation for social reinforcement. As expected, experimental Ss in the High Dissonance condition who committed themselves for low reward ($1.00) responded less to social reinforcement, i.e., they showed a smaller increase in response strength of emission of verbal behavior than Control Ss or Low Dissonance Ss who committed themselves for high reward ($5.00).
