Excellent point. It's may not be one thing, but experience would definitely be high on the possibles list. All kinds of fascinating things - do we remember better in color or mono? Zapruder was B&W (I think), Vietnamese napalm girl victim B&W(?), Kent State screaming girl - I don't remember - color I assume.

I'm not sure what effect the frentic, fast cut, hyper candy-colored media world may have on developing norms of perception etc. - not sure I want to know :-)
