Paradigm. Participants had to solve either a magnitude comparison or a parity judgment task based on the units of the two-digit numbers presented on the screen (A,B, standard trial). In all tasks, in-between the standard trials, in 20% of the cases, a question trial was presented indicated by a colored fixation cross (A,B, question trial). In Experiment 1, participants had to answer the additional question, whether the previous number was larger or smaller than 50, after the fixation cross turned into red (A). In Experiment 2, participants had to answer the additional question, whether the fixation cross turned into red or green (B). Thus, in Experiment 1, participants had to concentrate on the two-digit number as a whole for answering the question trial, whereas in Experiment 2, the decades were irrelevant for solving the normal as well as the question trials.
