Here we show that discriminating between different signal modulation rates can be easier when stimuli are presented in two modalities (vision and audition) rather than just one. This was true even when the single modality signal was repeated. This facilitation did not require simultaneous presentations in both modalities and therefore cannot rely on sensory fusion. Signal detection threshold for bimodal signals and double single modality signals were found to be equivalent indicating that thedoi:10.1167/7.11.14 pmid:17997668 fatcat:k665ihiwljaajimpcmfm3lhs2e
