David Eagleman on why reality is an illusion

[Jud]

Eagleman had a series on the Public Broadcasting System here in the US that was excellent, all about different aspects of human brain function.  (One particularly interesting segment showed how magicians direct attention away from where the trick is actually happening.)  I've posted a short segment from that program many times in the forums, and here it is again.  If you think of color as frequency and brightness as amplitude, the potential applicability to audio becomes more evident, I think: It may not always be the most measurably accurate reproduction that creates the most believable illusion of reality.

All participants will perceive the same phenomenon, which is the result of how color is perceived. Color has no "reality" outside of our perception, so there is no sense in speaking of an "illusion". 

 

Eagleman's examples are fun, but I would be careful in the conclusions that can be drawn from them. 

 

If you'd like something specifically from the audio area, there is this:

And regarding "all participants will perceive the same phenomenon," not so in the case of these audio demonstrations:

 

"Many of them show that people can differ strikingly in the way they hear very simple musical patterns."
