summaryEvents in the world typically generate signals in multiple modalities that are sensed at more or less the same time. This poses the question, to what extent is timing critical for the combination of the senses. Recently we have investigated whether the auditory and visual systems compensate for the physical delay between the transmission time for auditory and visual signals, using an implicit measured of audio-vision timing – the stream-bounce illusion. We address the question of whether a visual target that is temporally correlated with a sound pattern would “pop out” from a set of uncorrelated target. We also have investigated whether the discrimination of an abstract temporal pattern (temporal frequency) carried by two modalities might be better than single modality discrimination. In each case the combination of the senses seems to require attention-based processing rather than automatic amalgamation of signals.
