How do visual illusions work?
« on: 18/05/2016 10:24:09 »
Why can I choose how I perceive some illusions but not others? With some visual illusions I can choose to shift my focus e.g. with the face/vase illusion I can see the face then refocus and see the vase (
Other illusions like the spinning dancer I have to close my eyes or look away and then look back if I want to see the alternate illusion (

What's going on here? Is it because the illusions are 'happening' in different parts of my brain? It because I'm dealing with motion vs static images?
P.S. best of luck discussing visual illusions on the radio.
