Results of Experiments 1–4 (all trials).
Left column: mean reaction time (RT in ms) as a function of key distance (close, far) and Stroop congruency (congruent, incongruent, neutral) for all trials. Error bars represent SEM between participants. Right column: effect of key distance defined as mean RT difference between close and far conditions, for each Stroop congruency (congruent, incongruent, neutral), and averaged across all congruencies. Error bars represent SEM of mean close-far differences between participants. For the correct interpretation of these error bars see Franz and Loftus .
