(A) Physical set-up. Participants view stimuli on a large screen. (B) Illustration of the artificial scotoma as shown to participants once every 10 trials in Experiment 1. (C) Sequence of events in the experiment: (i) The artificial scotoma hides one of the two stimulus locations and the participant starts the trial by looking at the central fixation circle and pressing a joystick button; (ii) the stimulus is visible in a nonscotoma location; (iii) the hidden stimulus is revealed only when a saccade is made into the scotoma; (iv) the participant indicates whether the stimuli are the same or different; and (v) accuracy feedback is given.
