Regarding the performance until the first successful trial between the colored and non-colored sequence groups, two-sample t -tests showed a significant difference of total number of button presses [ t (36) = 2.15, p < 0.05, d = 0.70; colored sequence group, mean = 185 times; non-colored sequence group, mean = 248 times] and a marginally significant difference of mean button press time [ t (36) = 1.91, p = 0.063, d = 0.62; colored sequence group, mean = 734 ms; non-colored sequence group, mean = 668 ms], but did not show a significant difference of total working time [ t (36) = 1.46, p = 0.15, d = 0.47; colored sequence group, mean = 135 s; non-colored sequence group, mean = 163 s].
