Unproven assertion: 80% of our perception, learning, cognition and activities are mediated at least to some extent through vision

Despite almost unlimited access to the widest global collections of peer-reviewed publications, the  “eighty percent” quote remains unconfirmed by any peer-reviewed source.

The closest we could come for the source was two sources for those stats: was a book, Telling Ain’t Training, Chapter Three, “The Human Learner”, pages 19-22 by Dr. Harold D. Stolovitch and Dr. Eric J Keeps and Brain Rules, Chapter 10, Vision Trumps All Other Senses by Dr. Jon Medina, pages 221-231. Dr. Median is a neuroscientist and lists additional sources in his book.

There is some additional data on this page of his website http://brainrules.net/vision. Dr. Stolovitch and Dr. Keeps are cognitive researchers and also list additional sources in their book.
