Choice response times to visual word and symbol verification tasks were compared for left and right stimulus directions. The results indicated that true statements were responded to more quickly than false statements but that left and right produced equal response times. A strong stimulus-response (S-R) compatibility effect of question (true vs. false) and location of response key (left vs. right side of keyboard) was found. This S-R compatibility effect was based on the concept of verification instead of the left vs. right direction of the stimulus and the corresponding response key per se.
