Since learning more about perceptual organization in psychology class, I now know that this artificial difference in rate can be classified as motion parallax, just as the snow fall that you described can be categorized as motion parallax as well.Cao, A., & Schiller, P. Last time I made the trip to State College I was looking out of the window and noticed that the cars driving past mine seemed to be moving extremely fast, while the mountains in the background seemed to be moving at a much slower rate. For example, on the ride from Philadelphia to State College there are many mountains, rivers, and tons of traffic. I have noticed that whenever I am on road trips and looking out of the window, objects far from be appear to be moving very slowly, while objects close to me are moving extremely fast. I have also noticed similar things with motion parallax, but in a different context. That is a good point, usually we wouldn’t think twice about the rate at which snow is falling, but now that we have learned about motion parallax it is interesting to see how something as quintessential as snow fall can be applied to topics in psychology.

Have you ever experienced a similar phenomenon? These illusions are so powerful that they could have made me think that the snow actually was falling quickly closer to me, however I don’t believe this would even be possible. Perceptual organization examples such as this are interesting and can help us to understand more about the illusions that our eyes create. Parallax is an apparent displacement or difference of orientation of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Prior to this class, I probably wouldn’t have thought twice about the rate of snowfall. As the viewpoint moves side to side, the objects in the distance appear to move more slowly than the objects close to the camera. So, when I looked at the snowfall, my perception was that the snow was falling at different speeds everywhere that I focused my attention. Our eyes trick us into thinking that closer objects are moving faster and farther ones slower because with monocular cues such as relative size, interposition/occulsion, aerial perspective, linear perspective, texture gradient, and, of course, motion parallax, our depth perception only uses 1 eye to judge distances. Motion parallax is when objects that are closer to you seem to move at a quicker pace than those farther away from you. This is when I realized that I was observing the monocular cue known as motion parallax that we had learned about a few days prior. However, the speed of snowflakes was not different right next to my window compared to a few feet away. When I looked at the snow closest to my window, it seemed to fall quickly and, at times, almost violently. This was that as I looked at the snow falling closest to the brick wall, several feet away from my window, the snow seemed to fall very peacefully. The speed appeared to change with the wind, so I watched for a minute and noticed something peculiar. Last Thursday, as I was getting ready to head out to my calculus quiz, I looked out the window adjacent to my desk and noticed flurries of snow.
