Perception is shaped by learning, expectation and memory hence making this theory an active signal of passive receipts which involves both the bottom up and top-down effects of sensory inputs. The top down process is mainly used in building the higher information levels such as shapes of objects and recognition processes. While the bottom up processes include the individual’s conceptual and expectation for example knowledge which plays a major role in perception influence. Perception takes place subjectively in a most effortless process outside conscious know how hence its dependency on the complex functionality of nerve organisms. Understanding of perception amongst psychologist since the growing of experimental psychology in 19th century has given rise to various techniques like psychophysics which is a measure of perception effect under physical qualities of inputs. This discipline can also be studied in terms of information processes computationally. The extend by which sensory qualities for examples smell, sound and color existing in objective reality are some of the philosophical issues of perceptual rather than in mind of the individual. Although viewed as passive receptors traditionally, the study of ambiguous images and illusions shows that brain’s system attempts to make sense active and preconscious to their inputs. Perception is still viewed as hypothesis testing in various debates with respect to active process. Even though sensory information is not complete and varies rapidly, the brain perceptual system enables an individual perceives the world around as stable. This is because most human beings and animals brains are made in a modular manner with many processing area of sensory information. Some are believed to have maps as forms of sensory modules to help in mapping world across the brain surface. The modules are connected and influenced by each other for example the taste is much influenced by the odor. Psychologists such as Aristotle has proposed common sense over 2000 years past to explain how human beings and animals perceive qualities which are common but different in sense such as form, number and unity. Philosophers such as George Berkeley and Locke over centuries later have proposed that human beings need to assimilate information across different sensory channels before they perceive it as the output for example the ringing bell to be differentiated from light and sound. By doing this, it depicts that the brain is able to pose the binding perception problem to help in the construction of coherent world of information. This critical thinking of perception has dominated in the 20th century which included Piglet’s cognitive theory of development. According to Horry &amp. Wright (2009), this psychologist argued that, assimilation takes place gradually over a period of time as an individual grows and develop in the first few years as they interact with objects and coordinate information in their sensory organs. Young children are taught how to perceive information by their parents prior to assimilation through unrelated sounds, sights, tactile impressions and smell just as the buzzing confusion as Piaget’s theory was described by William in 1890.
