Abstract

To integrate the increasing and decreasing effects of monetary incentives on creativity, we assumed that both effects were real and individual's type of motivation would moderate the effects. We used WPI scale(Amabile, Hennessey, & Tighe, 1994) to measure individual's intrinsic and extrinsic motivation. Intrinsically motivated group were composed of high in intrinsic but low in extrinsic motivation, extrinsically motivated group were composed of high in extrinsic but low in intrinsic motivation, and dually motivated group were composed of high in both intrinsic and extrinsic motivation. The intrinsically motivated group showed the decreasing effect in study 1 using algorithm task and study 2 using heuristic task The extrinsically motivated group showed the increasing effects in both studies. And the dually motivated group showed the increasing effects in study 1 but the decreasing effects in study 2. We concluded that the effects of monetary incentives on creativity were moderated by individual's type of motivation.
