9.72, p = .0004, ε = .83; simple contrasts, right/left press vs. silent count, F[1,44] ≥ 11.5, both p = .001; right vs. left press, F[1,44] < 1.0, n.s.). However, these response-related effects were substantially reduced in patients (right press, −0.13 ±1.17; left press, −0.10 ±1.10; silent count, 0.00 ±0.92) compared to controls (right press, −0.48 ±1.14; left press, −0.51 ±0.99; silent count, 0.08 ±0.94), resulting in a significant response mode x group interaction (F[2,88] = 4.48, p = .02, ε = .83; group interaction contrasts, right/left press vs. silent count, F[1,44] ≥ 4.44, both p < .05; right vs. left press, F[1,44] < 1.0, n.s.).
