Perception begins when the human brain receives data from body’s five senses touch, sight, taste, smell and hearing.

Without being able to organise and interpret sensations, life would be just black and white, meaningless.

Bottom-up processing is also known as data-driven processing, this is because perception arises with the stimulus itself. Processing conveys from one direction of retina (back of the eye) to the visual cortex and with each successful stage the visual pathway carries out more complex analysis of the input. We take in a lot of information from our eyes however Gregory stated that 99% of the information gets lost before reaching the brain. Gregory 1970 uses three types of examples to support his evidence; they are: ‘highly unlikely objects tend to be mistaken for likely objects’, ‘perceptions can be ambiguous, and ‘perception allows behaviour to be generally appropriate to non-sensed object …show more content…
