Response and stimulus set-ups in the different experiments.

<p>A. Experiments 1 and 3–4, after <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0091432#pone.0091432-Lakens1" target="_blank">[3]</a>: keyboard keys assigned to responses in the close (‘K’, ‘L’) and far (‘S’, ‘5’) distance conditions, respectively. B. Experiment 2: custom-made response keys were not labeled and could be adjusted in distance. C. Experiment 1: instructions about mappings of font colors to response keys were presented in the lower left and right corner of the screen. D. Experiment 4: instructions were presented centrally at the bottom of the screen.</p

Error rate (M, SD in %) in Experiments 1–4 as a function of key distance (close, far) and Stroop congruency (congruent, incongruent, neutral).
