Schematic representation of the visual and auditory mislocalization judgments. Left, auditory conditions. Shown is a representation of the speaker setup. Top, the physical jump size is shown as a motion to the right. Middle, the hypothetical perception of this physical jump size during fixation based on the shift of the PSE of the mean psychometric fit for fixation. Bottom, the extrapolation of the perceived jump size as a rightward saccade crosses the rightward apparent motion. The jump size is perceptually expanded by more than one stimulus level (i.e., 1 speaker separation). Right, visual conditions. Top, the physical jump size of the shortest stimulus separation is shown. Middle, the perceptual shift extrapolated from the PSE of the mean psychometric fit at fixation: the perceived jump size is somewhat elongated. Bottom, the perceptual shift of the rightward apparent motion across a rightward saccade. The perceived jump size is elongated by more than one stimulus separation, similar to what is observed in the auditory condition.
