Document Summary
What we perceive is a lot more rich and powerful than what we actually know. Form perception is the process through which the basic shape and size of an object are seen. Object recognition is the process through which the object is identified. Object recognition begins with the detection of simple visual features. However, our perception of the visual world goes beyond the information given . An early twentieth-century movement known as gestalt psychology captured this idea as the whole is different from the sum of its parts . The necker cube is an example of perception going beyond the information given: Two different perceptions of depth are possible, given the line on the page. In the face-vase figure, two interpretations are possible, each based on different figure/ground organization. This again shows that perception goes beyond the information given . These example might suggest that perception proceeds in two stages.
