Psychology Essay Essay Omkar Kawade Charles Ramskov Psychology Essay Perception can be defined as the process of how an organism interprets a sensation. Many psychologists studied different types of perception, such as Constructive Perception (top-down) that was studied by Rock, Neisser, and Gregory.

When Eddie sees this arrangement of keyboard functions, he sees a smiley face. However, Kevin, a person who has no social interaction through the computer and/or Internet, sees this simply as a colon placed next to a right parenthesis sign. Direct Ecological (bottom up) perception is an inductive reasoning process. Gibson stated his theory of bottom up perception was basically visual perception and the information needed was available from the proximal stimulus that was produced by the distal stimulus.
