Re: [Yasmin_discussions] multi modal illusions

The Roger's quote on 'cross modal illusion' remembers me the
cross-sensory neurological
condition called synesthesia. Studies with synaesthetes have identified
differences in patterns of brain activation and connections. A synaesthete
connects colors, words, taste, musical intervals, building cross-sensory
memories. An interesting book concerning synesthesia is "Wednesday Is Indigo
Blue". In this book, Richard Cytowic and David Eagleman explain the
neuroscience and genetics behind synesthesia's multisensory experiences.

> Although
> ambiguous and conflicting sensory information from different sensory
> modalities is common, people seldom experience perceptual ambiguities or
> conflict between senses. Just as the retinal nerve blind spot is filled in
> and seldom seen, conflicting or otherwise confusing sensory information is
> resolved in favor of the most appropriate modality, eliminating the
> confusion from conscious experience. The ventriloquism effect and auditory
> driving are two examples of perceptual phenomena arising from this sensory
> override. This research explores the hypothesis that velocity perception is
> subject to the same effects. Subjects were presented with two bimodal
> (auditory-visual) stimulus pairs and asked to determine which of the visual
> stimuli was moving faster. In a V2A2/V2A1 condition, participants responded
> significantly more frequently that the first visual stimulus was faster
> than
> in any non-target condition. This effect was not found for V2A2/V2A3
> trials.
