Figure 1

A depiction of the experimental conditions and results in Roseboom et al.19. (A) Identical cross-modal flankers (pure-tone here) presented asynchronously with the visual flashes resulted in a strong impression of motion (indicated by the heavy red arrows). (B) When successive flankers differed (audio noise and pure-tone here), the influence of the asynchronous flanker timing was reduced, resulting in a much weaker impression of motion. (C) When successive flankers differed by pair and the pairwise features were in conflict with the influence of timing, the perceived motion direction was ambiguous (depicted by the bi-directional blue arrows). (D) When successive flankers differed by pairs and there was no temporal difference between visual flashes and cross-modal flankers, this resulted in an impression of rightward motion of a similar magnitude to that apparently driven by temporal ventriloquism. Similar results were obtained when the difference between flanker signals was across-modality (tactile-audio) as when it was within-modality (pure tone-audio noise).
