The brain may be able to perceive and understand the gist of the paragraph due to the context supplied by the surrounding words. In , psychologist Richard Gregory stated that perception is a constructive process that depends on top-down processing. He explained that past experience and prior knowledge related to a stimulus help us make inferences. For Gregory, perception is all about making the best guess or a hypothesis about what we see.

This event leads to the creation of a perceptual hypothesis about the stimulus, based on his memory and past experience that may be related to it.

When it comes to visual illusions, such as the Necker tube, Gregory believed that the brain may create incorrect hypotheses, leading to several errors of perception. In the bottom-up processing approach, perception starts at the sensory input, the stimulus. Thus, perception can be described as data-driven. For example, there is a flower at the center of a person's field. The sight of the flower and all the information about the stimulus are carried from the retina to the visual cortex in the brain.

The signal travels in one direction. J Gibson criticized the explanation of Gregory regarding visual illusions as they are merely artificial examples, not images that can be found in a person's normal visual environment.

Being a strong support of the bottom up processing approach, Gibson argued that perception is not subject to hypotheses; rather, perception is a direct, "What you see is what you get" phenomenon. He explained that our environment can sufficiently supply details related to the stimulus e. Motion parallax supports this argument. When we travel on a fast moving train, we perceive that objects closer to us pass by faster, while farther objects pass us slowly.

Thus, we are able to perceive the distance between us and the object that pass us by based on the speed at which they pass. Check out our quiz-page with tests about:.
