[Xmca-l] Re: imagination and controlling the perception of visual illusions.

Lovely Huw!

You say that the speed of the train suggests that it is going away. But why
would you assume that a train would be coming into a platform from the
right? (my experience with most CTA platforms in Chicago is that, from the
perspective of a person standing on the platform, they enter from the left).

It seems that you are entirely correct in suggesting that how we see things
depends on culture (qua memories/experience/expectancies - e.g. from which
direction a train enters a station - reminds me of an old story the German
spy in England who was able to go unnoticed until, upon crossing an empty
street, he looked to the left before crossing).


p.s. And thanks for this - I'll use it for my Anthro of Experience class
since we have been doing visual perception! And I'm a sucker for a good
This also seems an opportune time to remind all of Etienne and Mike's paper
Minding the Gap. Their degradation of the stimulus example comes to mind as
another nice example of perception being mediated by culture and history.
