Average localization performance observed (observ.) for perisaccadic visual, auditory, and bimodal stimuli and predicted (predict.) for bimodal stimuli (Eqs. 1–3 in Materials and Methods). A, The average values of bias. B, The average thresholds (before being averaged, thresholds from each subject were normalized to the bimodal observed threshold). Error bars indicate SEM. Observed values for the bimodal condition are very similar to the predicted ones and significantly different from those observed in the unimodal conditions; as predicted by Equation 3 in Materials and Methods, the bimodal localization threshold is significantly lower than both visual and auditory thresholds (*p < 0.05, bootstrap t test with 5000 repetitions).
