Introduction
“With reference to theories of visual object recognition outline the ways in which faces appear to be “special”. How might such appearances be deceptive and in what ways does this bear on competing theories”.
Visual perception is an extremely active process in which the perceiver looks beyond the information that is given to construct a vision that can be interpreted and constructed to make sense in the visual world. Many theorists have come up with different ideas of how we perceive objects and recognise them to be what they actually are. Constructivists believe that we perceive things based on our expectations and knowledge of the world and that we are influenced by a hypothesis. This in contradiction compares to the ecological approach, which looks more scientifically at the idea of an optical array. From these initial ideas theorists such as Bierderman and Marr have based their theories of object recognition and constructed such ideas based around how we come to see an object through a series of different stages (Eysenck and Keane, 2001). Through looking at object recognition the question arises ‘are faces interpreted in the same manner or are they recognised differently?’. This question has lead to research based on whether faces are constructed as a structural element or as an image as a whole. These theories will be examined to discover the ways in which faces appear to be ‘special’ and whether how we perceive them leads to misinterpretation in the way that they are processed.
The concept of visual perception has been widely debated upon. R.L.Gregory looked at the constructivist view and stated that “Perception is not determined simply by stimulus patterns.

They proposed that recognising a 3d object involved matching a 3d model against a series of 3d objects stored in memory and that identification of concavities were identified first before anything else. This then gave the basis for the overall object recognition. Overall Marr’s explanation of object recognition does explain how the visual system could work however it operates on a greyscale, monocular level which doesn’t contain enough information to individualise each object.
