Follow-up tests showed that the difference between central and noncentral blocks was significant, t (23) = 2.73, p = .01 (one-tailed directional t test: p = .006), 4 Cohen’s d = .55; the differences between central-signal and no-signal blocks, and between no-signal and noncentral blocks were marginally significant; t (23) = 1.91, p = .07 (one-tailed directional t test: p = .035), Cohen’s d = .39, and t (23) = 1.81, p = .08 (one-tailed directional t test: p = .041), Cohen’s d = .37, respectively.
