Humans and animals prefer immediate reward rather than delayed one. In other words, a future reward is felt discounted. The speed of discounting is expressed with the parameter K, which is called discount rate. Problems related to time discounting often occur in everyday life. For example, if we put up with purchasing a product by impulse, we may succeed in savings as a future reward. On the other hand, if we purchase a product by impulse, we will get a satisfaction and an effect of product as an immediate reward at the expense of a future reward. This study focused on embodied cognition for adjusting discount rate easily and solving problems mentioned above. Our experiment revealed that a high-power posture tended to reduce discount rate, which means that savings will be easier to succeed. This occurred only under condition where the reward is small.
