(A,D,G) Stimulus timing. Participants prepared a saccade at the offset of the fixation target (ft), which corresponded to the onset of the saccade target (st). In the 150 ms before the saccade, a discrimination target (dt) was briefly shown at one of the 32 possible positions. Then, no cue was shown (A), or a cue was shown 50 ms before the dt and about 100 ms before the saccade (D), or a cue was shown 200 ms before the dt and about 250 ms before the saccade (G). (B,E,H) Normalized sensitivity maps. Averaged normalized sensitivity (d') observed across participants and displayed using a color-coded linear scale going between 0.25 and 0.75 (see Materials and methods). Asterisks indicate significant differences (p < 0.05) in sensitivity found between a particular position of the dt and the average of all the other tested positions. (C,F,I) Averaged normalized d’ obtained at four positions of interest (black squares) and at their corresponding surrounding positions (dark gray squares). Error bars show SEM and asterisks indicate significant comparisons (p < 0.05).
