Cross-Modal Perceptual Organization in Works of Art

Direction of visual apparent motion driven by perceptual organization of cross-modal signals.

A critical function of the human brain is to determine the relationship between sensory signals. In the case of signals originating from different sensory modalities, such as audition and vision, several processes have been proposed that may facilitate perception of correspondence between two signals despite any temporal discrepancies in physical or neural transmission. One proposal, temporal v...

Perceptual Learning from Cross-modal Feedback

It does belong together: cross-modal correspondences influence cross-modal integration during perceptual learning

Experiencing a stimulus in one sensory modality is often associated with an experience in another sensory modality. For instance, seeing a lemon might produce a sensation of sourness. This might indicate some kind of cross-modal correspondence between vision and gustation. The aim of the current study was to explore whether such cross-modal correspondences influence cross-modal integration duri...

Neural substrates of perceptual enhancement by cross-modal spatial attention.

Orienting attention involuntarily to the location of a sudden sound improves perception of subsequent visual stimuli that appear nearby. The neural substrates of this cross-modal attention effect were investigated by recording event-related potentials to the visual stimuli using a dense electrode array and localizing their brain sources through inverse dipole modeling. A spatially nonpredictive...

Visual Cross-Modal Re-Organization in Children with Cochlear Implants

BACKGROUND Visual cross-modal re-organization is a neurophysiological process that occurs in deafness. The intact sensory modality of vision recruits cortical areas from the deprived sensory modality of audition. Such compensatory plasticity is documented in deaf adults and animals, and is related to deficits in speech perception performance in cochlear-implanted adults. However, it is unclear ...
