Experiment 2 Results. a: Group mean results for Experiment 2a, with two adaptors on screen in each trial, and for comparison, Experiment 1a (from Figure 2). Both results are respectively significant, p<.001, and there is no significant difference between them (p>.05). b: Results of the progressive overlapping exclusion analysis for Experiment 2b. We find a strong presaccadically-induced face aftereffect only when the deviation between saccade landing and the center of the target face is between within 0.5° and 1.5° of the center of the face (asterisk indicates p<.001; Bonferroni-corrected α = .01; note that the 0–1° error bin is trending at p = .015). Given the size of the stimulus (3.6° wide by 4.3° high), this indicates that the saccade must land where the adaptor face had been. When saccade error is higher, we observe no significant aftereffect, p>.05 (in the 1°–2°, 1.5°–2.5° and 2°–3° saccade error bins). Error bars for this analysis only are bootstrapped 1SD.
