Population medians and SDs of reaction time and percentage correct for different trial types and both contexts (SAME, OPPOSITE). Wilcoxon’s test,
↵*p < 0.05, perturbation trials versus no perturbation trials;
↵**p < 10−10, perturbation trials versus no perturbation trials.
↵aNo significant difference between no-perturbation trials in SAME versus OPPOSITE.
