| Outline of Final Research Achievements |
Many exercise tasks in which ace and mistake are next to each other is very different from the target position to be aimed in in advance, and the decision on which position to select as a target has an important meaning for performance . Therefore, in this research, we developed a new motor task that imitates such a situation and examined human's decision making process under risk using Bayesian statistical model. Result revealed that in tasks with a high risk-high return type gain function, the expected score decreases due to the decision making bias, and the progress of learning is also delayed. In addition, experiments using transcranial magnetic stimulation suggested involvement of the dorsolateral prefrontal cortex on risk orientation.
