Illusions

These are some of the optical illusions that I enjoyed looking at for this assignment:
~Contrast Constancy
~Spiral Aftereffect
~Muller-Lyer Illusion
~Munker-White Illusion
~Pyramid Illusion
~Scintillating Illusion
~Hermann Grid, Curving
~Lilac Chaser

These illusions were very interesting. I never realized how many tricks our eyes play on us until I was going through the illusions for this assignment. I learned that our perceptions may not always be what we might think. For example, in one of the illusions there was picture of a girl sitting in a chair looking out at the night sky. In the sky was the image of a moon. The moon was drawn bigger because that is how we perceive the moon being; however, in actuality the moon was a third or half the size drawn.

I think what surprised me the most when looking at these optical illusions was the vastness or variety of optical illusions. A specific optical illusion that surprised me was the optical illusion called Muller-Lyer Illusion. In this illusion there was a line with a line segment. The goal was to affix the line segment in the center of the line. Well, obviously my perception of the center was completely off from the exact center of the line. So when I clicked ruler I could plainly see that my mark was off by at least an inch.

I don't know if these illusions have really changed my perception of the world; however, it does make think whether or not I am seeing the full picture.

I believe that these experiences affect my everyday life through encouraging me to think more. For example, are those two objects really the same length, are they different colors or are they the same but the shadow makes them look different, or is that really center or in the center? I think these questions will certainly be present more often than they would have been if I had not seen the optical illusions.

  1. I also found these very interesting. But you already knew that because we were looking at them together and I told you. I think it is amazing how how eye lie to us. And that because they keep moving we think we see an image that is moving but really it is a still picture.
