Perception is basically the principle of how we perceive information of the world through our senses and how it is then processed to allow us interaction with the environment. In our natural environment we are surrounded with sensory information but we only take in a small amount of that information. For the purpose of this assignment the general principle which will be researched into, is the theory of having a two-way flow of information or more simply the bottom-up and top-down processors. Both top-down and bottom-up play important roles in visual perception, they contrast with direct and indirect theories but also compensate each other when visually tough tasks occur. Both approaches give details and explain how visual illusions occur through the information processing of visual perception. The top-down approach clearly states that learning and prior knowledge is an important part of the process

Virtually every visual perception task faced in everyday life will involve the use of both approaches and has been a major contribution within the field of visual perception and cognitive psychology.

Because of its contribution to the unraveling of cultural constructions, this insistence on the arbitrariness of standards of pictorial objectivity and realism is a common feature of contemporaly visual scholarship. Nonetheless, we should not take for granted that the basic premises of this approach are entirely correct. First of all, it is questionable whether the general public has ever been as trusting of photographic truth as academic scholars sometimes assume. Photographic historian Vicki Goldberg (1991, p. 24) has pointed out that, even as far back as the 1860s, the use of photographic evidence in a famous post-Civil War trial had to be accompanied by expert testimony to reassure the jurors that the pictures were fair representations of the events portrayed in them. As Sturken and Cartwright them-selves point out (p. 20), any feelings of trust that the public may have had in photographs is likely to have eroded considerably since the advent of large-scale, and widely publicized, digital manipulation

It may be, then, that those of us who study visual communication professionally are somewhat self-deluded about the extent to which the general public needs our guidance in order to be able to see through images (Helfand, J. (2001).

Summing up, one must point out that the evidence proposed is not by any means the extent and depth of the literature available

Perhaps one could argue indefinitely regarding the philosophy of perception, and as previously asserted no one theory is correct. However, in the view of conclusions the aim of this essay has been achieved by providing a critique of the evidence proposed to allow the reader to have a comprehension and critical evaluation of the constructivist model.
