Research Abstract

It is usual that some kind of the extent of information investors have are assumed in the securities market. For example, there are two groups, more informed investors and less informed investors in this market. We add mediam informed investors to these groups. Thus, we divide a market to three parts. We repeated a laboratory experiment many times. Next, We analyzed it how the results changed by an fMRI (functional magnetic resonance imaging) experiment.
We found that more domains of the brain in the medium informed investors are activated than other two investors.
