The stimulus mean was 1, 11, and 31 in separate simulations. The stimulus range was 1–71, which corresponds to 2.0 and 8.0 s. Easy conditions correspond to durations 2.00 and 2.44 s and stimulus categories 1 and 11 in the simulation. Difficult conditions correspond to the duration of 3.62 s and stimulus category 31 in the simulation
