Gregory proposed that our past experience‚ knowledge‚ expectations and motivations can affect how we interpret the visual information we receive‚ therefore affecting our perception. He suggested that how we see objects is highly brain driven and indirect‚ and the process takes place so fast that we are unaware of the object in ‘normal perception’; Gregory would say that ‘a perceived object is a hypothesis’. Perceptual constancies show how the brain compensates to provide a constant perception of

Gibson and walk (1960) investigated depth perception in human infants. The used a piece of equipment called “The visual cliff”. The visual cliff was used to give the impression of depth. Gibson tested 36 babies between the ages of 6 months – 14 months. They placed them individually on one side of the apparatus and got their mothers to encourage them to cross the apparent cliff edge. This was done to see if the infants had an innate awareness of depth. The found that babies would happily crawl across

90% is lost by the time it reaches the brain. This occurs due to information being lost through the visual system‚ as well as the brain letting go of any unnecessary information. Gregory used the Hollow-Face illusion (also known as Hollow-Mask illusion) as an example of an optical illusion to explain how expectations can affect how we perceive objects. In this case how the observer perceives a concave mask of a face which appears as a normal convex face. While a convex face will appear to look in

Navon 1977 Navon investigated the Gestalt law according to which ‘the whole is more then the sum of its parts’. Participants were asked to identify either the small letters making up the large letters‚ or the large letter. The small letters were sometimes the same as the large letter and sometimes different. It took longer to identify the small letters when these conflicted with the shape of the large letter. But there was no difference in the time taken to identify the large letters. This could

Gibson believes in the direct theories of perception which he used the theory of bottom-up processing to explain visual illusions whereas Gregory believes in the indirect theories of perception and he used the theory of top-down processing to explain visual illusions.
