New experimental paradigm: Reaction to own response with time lag
We propose the new experimental paradigm in this report. Traditional and usual method of psychophysical paradigm is based on function between physical input and psychological output. In contrast, in our experiment, the participants had to make judgment based on products of their own responses which had large time lag to make exposure. This experimental situation was very difficult for participants. The participants needed "the feedforward-like judgment" and their performance did not show improvement through repetition of experience.
