Data of Temporal Frequency Discrimination in Amblyopia

A flickering disk was used for visual stimuli. A two alternative forced choice (2AFC) staircase paradigm was used to measure the temporal frequency discrimination thresholds of amblyopic eyes, fellow eyes and normal eyes under reference temporal frequencies of 5, 10 and 20 Hz. The data of just-noticeable differences and Weber fractions were analyzed statistically. Moreover, the temporal frequency discrimination thresholds (5 and 10 Hz) of the subjects were measured under the circumstances of more and less attention distribution. The changes in temporal frequency discrimination thresholds were compared between amblyopic and normal eyes when attention was allocated. <br>
