The percentage of correct and incorrect answers of the subjects in the healthy group, L group or R group, is shown. White noise or female voice was presented to each subject from each of the seven indicated directions three times in random error. An answer in the posterior field that was symmetric around the horizontal line to the presented anterior direction, was considered to be correct.
