抄録	Recent studies in neuroeconomics and econophysics revealed the importance of reward expectation in decision under uncertainty. Behavioral neuroeconomic studies have proposed that the unpredictability and the probability of an uncertain reward are distinctly encoded as entropy and a distorted probability weight, respectively, in the brain. However, previous behavioral economic and decision-theoretic models could not quantify reward-seeking and uncertainty-aversion in a theoretically-consistent manner. In this paper, I have proposed that generalized Helmholtz free energy in Tsallis' non-extensive thermostatistics can be utilized to quantify a perceived value of an uncertain reward. Future study directions in neuroeconomics and econophysics by utilizing the Tsallis' free energy model are discussed.
