The effect of reward and information on subsequent intrinsic motivation were investigated. In Exp. 1 subjects were given information that they were high or low in interest in the task. High-information subjects were more intrinsically motivated than low-information subjects. The effect of information was discussed in terms of self-perception theory. In Exp. 2 subjects were assigned to one of three conditions : (1) no reward condition, (2) reward condition, (3) reward with information condition. In the 3rd condition subjects were given information that rewarder had no intention of controlling subjects with the reward. The reward condition was found to reduce intrinsic motivation relative to no reward condition. But reward condition accompanied with the appropriate information did not decrease intrinsic motivation relative to no reward condition. The result suggests that the effect of rewards on intrinsic motivation depends on the interpersonal context of rewarder and rewardee.
