This research explored the influence of myopic loss aversion on risk preference in investment decision-making with the time horizon of an investment and the frequency of feedback on the information as two indicators of myopic loss aversion and imitation of real world investment decision-making as the experiment task.

Some experiments were demonstrated on bistability using acousto optic (A O) devices (1D and 2D) and a driver which can provide frequency feedback, and succeeded in implementing bistability by means of frequency feedback.

Many experiences shows, in the motor skill learning, not always feeds back frequently, is more prompt, more is clear about well, There are many experiments from the overseas that prove“100% feedback frequency not the best instruction form”, and what actually have the best promote effect, there was no a consistent conclusion.
