An experiment was conducted to determine if improvement in resolution acuity due to exercise was based on changes in sensory discrimination or decision criterion. Two subjects participated in 15 exercise sessions of 1100 kpm per min. on a bicycle ergometer and 5 control sessions. After each exercise and non-exercise condition, resolution acuity was determined using a Yes-No indicator-response method. Significant improvement of resolution acuity was found after the exercise sessions. Threshold probabilities did not change significantly when corrected for spurious Yes responses, suggesting that differences were probably effects in sensory discrimination.
