When asked to ignore stimuli in the visual modality and attend to the auditory modality, increased activity in the auditory temporal cortex and decreased activity in the visual occipital cortex can be observed (and vice versa).⇒
Task-irrelevant visual cues do not affect visual orienting (visual spatial attention). Task-irrelevant auditory cues, however, seem to do so.⇒
Semantical congruence can influence multisensory integration.⇒
In one of their experiments, Warren et al. had their subjects localize visual or auditory components of visual-auditory stimuli (videos of people speaking and the corresponding sound).
Stimuli were made
compelling' by playing video and audio in sync anduncompelling' by introducing a temporal offset.
They found that their subjects performed as under a
unity assumptions'' when told they would perceive cross-sensory stimuli, and when the stimuli were `compelling' and under a lowunity assumption'' when they were told there could be separate auditory or visual stimuli and/or the stimuli were made `uncompelling'.⇒
