In the physical- and the name-identity task, letters were presented in upper- and lower-case from A, B, D, G, H, E, F, L, R, M, T, and Q. They were arranged in triangular position: Two different probe letters were presented 1.6° above the fixation cross, one on each visual field, 2.68° to the left or right of the midline, and the target letter was displayed 1.6° below the fixation cross, 1.6° to the left or right of the midline. The fixation cross was always located in the center of the screen during the trial. All letters had the same dimensions of 0.95° horizontally and 1.3° vertically presented in white color on a black background (to reduce the light emitted from LED screen).
