Re: I'M A SCIENTIST ME
Your not a very good scientist then Dave 62.
If you're a neuroscientist and you want to understand the brain, one of the high difficulty-to-scientific value areas of study is the visual system because:-
1. The area is accessible to imaging, probes etc. on most animals as its located at the back of the head
2. The input is controllable (shine patterns on the eye)
3. Vision is the humans primary sense
4. Grey matter is structurally similar across brain regions (so insights in the visual system, to some extent, may carry to other areas like speech, executive control etc.)
Thus visual illusions found by psychophysicists are valuable effects that can be studied by in vivo experimentalists to find neural correlates between high level perception (it looks nearer) and low level neural representations.
I'll not defend some of the wacky practical implications, but the data generated in the experiment is not art.
