I decided to write my blog on the concept of apparent motion. Apparent motion is when we perceive motion even though there is no real motion. This was illustrated by a scientist by the name of Sigmund Exner who conducted an experiment where the participants perceived that the two sparks presented to them were actually one spark moving back and forth (Wolfe et al., 2012). However, it was actually two sparks that were just very close together and presented in rapid succession (Wolfe et al., 2012). The neurons in our motion detector system do not need actual motion to fire as evidenced by the perception of the participants in the experiment. Several things in everyday life make use of this concept. One example is TV. I watch TV every day and perceive movement on the television screen even though nothing is actually moving. To make it look like the figures on the screen are moving, there are many frames presented in a very short amount of time. As long as these images are presented at a fast enough pace, the viewer will perceive the illusion of continuous movement (Wolfe et al., 2012). For example, when I was younger I watched Bugs Bunny and he would run away from Elmer. This apparent movement was created with many (an example would be 100 frames a second) drawings presented very very quickly (Wolfe et al., 2012).This is very similar to other things that we see on everyday basis. Another example would be when I went to the movies to the Avengers. When people go to see movies and perceive movement it is very similar to the Bugs Bunny example. The only difference is that still photographs are used instead of drawings (Wolfe et al., 2012). This also the same process used for computers (Wolfe et al., 2012). Overall, apparent motion is a concept that surrounds us everywhere we look even though we may not be aware of it.
