Within modality effects are similar both in unisensory and cross-sensory trials and in both vision and audition; however, while auditory streams have a strong effect on visual temporal judgments, visual streams have a negligible influence on auditory temporal judgments. A–D, Mean ± SE perceptual weight, derived from linear regression of the observed responses, for the to-be-attended visual stream and the competing visual stream when counting flashes in the unisensory condition (A), for the to-be-attended auditory stream and the competing auditory stream when counting beeps in the unisensory condition (B), and for the perceptual weight for the to-be-attended and competing auditory and visual streams when counting flashes (C) or beeps (D) in the multisensory condition. E, Scatter plot for individual subjects plotting the perceptual weight given to the visual stream when counting beeps against the perceptual weight given to the auditory stream when counting flashes.
