Document Summary
A group of psychologists in germany called gestalt psychologists began to study how people perceive the world around them. With respect to perception, they firmly believed that the whole is different than the sum of its parts . They believed that people tended to perceive the whole stimulus rather than just putting together a collection of the stimulus" discrete parts. Consider the perception of movement you experience when watching a movie made by flashing slightly different static pictures every second: there isn"t continuous movement in or across any of these frames, but we still perceive continuous movement as we watch the rapid sequence of still pictures. The perception of the movie in its entirety is something more than the collection of thousands of still photographs. In the simplest scenario, you would have a small, enclosed region that is completely surrounded by a larger region, which would be the background.
