Mean RT and RT variability, as measured by SD, for each of the 3 RT test conditions.

RT Test Condition Mean RT RT Variability
RTclin 234 ± 28 ms* 26 ± 14 ms**
RTcompFB 301 ± 45 ms* 80 ± 54 ms**
RTcompNoFB 327 ± 52 ms* 88 ± 60 ms**

F2,60 = 81.66, p < .0001 for test of equality across groups; F1,30 = 93.07, p< .0001 for RTclin-RTcompFB comparison;F1,30 = 133.53, p< .0001 for RTclin-RTcompNoFB comparison; F1,30 = 11.14, p= .0023 for RTcompFB-RTcompNoFB comparison.
