    Understanding correlations in order to test speed-accuracy trade-off in experiments

    I understand that in experiments where the measures of interest are speed (reaction time) and accuracy, for an effect to be valid one needs to make sure there is not a speed-accuracy trade-off (SAT). Namely, as reaction time gets quicker for a condition, accuracy should also be better for that...
