Outline of Final Research Achievements

Humans and other animals can modify the choice behavior depending on the experienced decision outcome in the past. Subjective values are involved in the processes. However, in general, measuring the subjective values is a challenging task. The present study proposed novel framework for estimating subjective values from choice behavior using computational models called the reinforcement learning model. As a result, the validity of the proposed method was confirmed. In addition, a part of the physiological substrates and the neural substrates related to the subjective value were clarified.
