Performance on skin histopathology pre-test, post-test and delayed post-test. Results from 1^st-year students completing the perceptual and adaptive learning module and associated tests in the Fall of 2011 and 2012 (left and middle groups, respectively) and 2^nd-year students completing these in Fall, 2012 (right group). The delayed post-test was optional and was only administered in 2011. Pre-test and post-test performance of students completing the delayed post-test (not shown) was not significantly different from those who did not complete this test. a) Means and standard deviations using answer Accuracy, independent of RT; b) Means and standard deviations using Scores, for which responses occurring after the target RT of 12 s are scored as incorrect. A single asterisk (*) indicates P < 0.0001 and a double asterisk (**) indicates P < 0.0005
