title: Effect of feedback on estimates of visual sensitivity.
abstract: Estimates of visual sensitivity are often difficult to interpret because nonsensory factors may influence performance on a psychophysical task. We examined for 19 naive students, ages 10 to 40 yr., the effect of feedback on estimates of contrast sensitivity and found no evidence that feedback improves performance when compared to no feedback conditions.
