Optical illusion?

Post Reply New Topic

Hey guys,

Here's a cool optical illusion: http://www.exploratorium.edu/exhibits/mona/mona.html

A question for all of you: does that illusion work for you? As you can see, it expects the difference to "jump out" at you in the bottom set of pictures, but not in the top (upside down) set. Do you experience that or not?

Edit: When I say "the difference in the pictures" I do mostly mean the eyes, not the mouth. Sorry about the vague poll question!

I picked 'didn't jump out at me' because I've done so many of these things that when I saw the upside down pictures I could tell something was different with the one on the left but not what. Right side up I did notice one was smiling and the other frowning but I didn't catch how they altered it til I read the whole thing and even though I did notice a difference when they were right side up the differences didn't 'jump out' at me in my opinion.

The mouth jumped out at me immediately, but I didn't notice the difference in the eyes until the picture was flipped, possibly because I spend so much time looking at people's mouths.

Huh. The mouth did because that jumped out at me. You can't ask a question like that and then specify WHICH part jumps out at you.

I looked and then saw the difference in the lips when I looked down. I also turned my laptop upside down to see the change at the top and the same thing happened. I did the same with the bottom too to see the picture below change back.

I didn't notice the eyes until I read this thread. I guess I even lack eye contact in photos

Yeah it worked for me. Upside down they both look normal to me but right side up the 2nd one looks weird. I noticed the difference in eyes but didn't notice the mouth.

Heres a cool optical illusion

to me the table on the left looks thinner and longer than the one on the right but measuring them with a ruler, they have the same dimensions. Optical illusions always work on me. People with autism are supposed to be able to spot details better than they can see the big picture but thats not the case for me. This is pretty cool too

I can only see her turn clockwise, I can't seem to see her going anticlockwise even if I try. What about all of you? I'm ambidextrous so I probably have a relatively well developed corpus callosum which may be why I'm good at manipulating logic despite displaying all the traits of a right brain thinker.

Mona Lisa: saw the difference in just the eyes when both upside-down, difference in eyes and mouth when right-side up.

Table illusion: yes, they appear to be different lengths--I think there's a line illusion that does the same thing (lines the same length but one has arrowheads pointing inwards on each end and the other has arrowheads pointing outwards on each end).

Spinning dancer: I see her turning clockwise and I'm right-handed, which seems kind of odd.

I took an online brain-dominance test once and the two sides were VERY close to being equal.

Neither stood out...?

Mona Lisa, I noticed the eyes and not the mouth on the top picture. They were both obvious on the bottom right-side up picture.

The tables, yeah the left one looks longer.

The dancer, at first she was going clockwise but after I read the description on her left she started spinning counter-clockwise. I had to close and open my eyes a few times to get her going clock-wise again.

Yeah, they were both different. I just automatically saw the differences, because I tend to see details like that. I think I might have mentally rotated the top pictures, but I think I did so after I noticed they were different.

I didn't notice the eyes until mentioned here. Didn't notice the mouth until it was right-side up.
