  1. TAP = Test for Attentional Performance, Tea-ch = Test of Everyday Attention for children, D2 = D2 Test of Attention, SD RT = Standard deviation of reaction time, ° = p <.05 when corrected with Bonferroni.
  2. MANOVA group by time by test results: group F = 3.404, p = .013, time F = 9.473, p = .000; group by time F = 1.162, p = .364; hypotheses df = 7, error df = 22.
