It's not auditory," he said.
"Human beings are not olfactory animals, they're not auditory animals, they're visual animals," said Rosenberg, who said he attended that 1964 World's Fair.
This suggests that the origin of the difference in the secondary auditory cortex was not auditory but was instead somatosensory.
For example, one participant in a recent study told us: "It's hard to describe how I could 'hear' a voice that wasn't auditory; but the words used and the emotions they contained were completely clear, distinct and unmistakeable, maybe even more so than if I had heard them aurally".
However, the bark scale is not an auditory model and cannot simulate the frequency response characteristics of the basilar membrane in the cochlea.
Evidence for altered sensory processing comes from studies showing that, for individuals with autism, auditory perception in silence is not superior to auditory perception in noise, as it is in controls (Russo, Zecker, Trommer, Chen, & Kraus, 2009).
It is not clear whether auditory and visual information are provided through separate (auditory and visual) or mixed (auditory, visual and audiovisual) channels.
But it is not that the auditory system has disappeared, the researchers say in a paper in Biology Letters.
Sorensen (2007) proposes for instance that it is not a purely auditory phenomenon that we do sometimes identify and localize objects and events at their center, whenever a center is available.
It is very interesting to notice that it is not the individual auditory stimulus that affects the increase of motion of the subjects, but rather it is the combination of soundscapes, 3-dimensional sound, and auditory rendering of one's own motion that induces a higher degree of motion.
