Why Does Our Mind See Illusions

Why Does Our Mind See Illusions?
2
The Human brain put images together because it
has learned to expect things sometimes the data
might get a little confused. We may see
an illusion because we know what we are expected
to see, even though part of a picture or design
may not be completely there. The basis of this is
in how we perceive things.
3
That almost explains everything right there. If
our brain and eyes did not function like they do,
we would not see illusions like we do.
4
Is the left center circle bigger?
No, they're both the same size
5
Optical illusions just trick you into seeing
something else. They are an error in our
perception of the illusion.

Look at the words below from left to right. Say
out loud the COLOR not the word. This is a left
to right conflict. The right side of your brain
tries to say the color while the left insists on
reading the word.

Are the purple lines parallel or curved?

Keep staring at the black dot. After a whilethe
gray haze around it will appear to shrink.

What do you see?

Stare at the blue circles and move your head back
and forth from the screen. Do the outer circles
move?

What word do you see?
35
Do you see some squares or rectangles? Really,
this is nothing more than a bunch of lines going
in every which direction, but the way our mind
interprets these lines are totally different!!
36
Do the sides of the square appear to be bent in?
Wait, now that is Impossible! Believe it or
not, they are as straight as they come. If you
do not believe me, take a straight edge and
see for yourself!!!
