This is the part of the human brain that allows man higher intellectual and analytic functions compared to animals â€" perception. “Perception begins where sensation ends”. 1 In fact, many psychological studies agree that perception is what largely separates humans from animals. In the same way, perception is what separates each individual human being from each other. Each day, a human being is bombarded by unbelievable simultaneous stimuli from external sources. 2 These external sources are powered by all types of activities of nature â€" visual stimuli provided by the spectrum from a single ray of light thus reflecting all types of colors, sizes, shapes and distance; auditory stimuli via sounds of nature and the environment; olfactory stimuli owing to millions of chemical reactions; tactile stimuli given by various natural conditions such as snow, fire or the lack of proximity between the sensory organ and an object in nature; and taste stimuli from various chemical combinations and products of nature (fruits, vegetables, animals). Nerves connected to the sensory organs in the human body collect these information and pool them into the cerebral cortex for processing, or what is known as perception. As presented above, the function of the cerebral cortex as a processor of external information (stimuli), has obviously been patterned to analyze activities in nature. ______________________1 Valdes, J., Sensation and Perception, An Introduction to Psychology, Florida International University, 2003, p. 2. 2 Ibid. In relation to this, as seen by the Gestalt Psychology (a school of psychology that interprets phenomena as organized wholes rather than as aggregates of distinct parts, maintaining that the whole is greater than the sum of its parts3), perception is an activity of the human brain with the sole purpose of interpreting informatio n around the person. However, despite this, various studies have challenged this theory. In the study of Ione Fine, et. Al. on long-term deprivation and its effects on visual perception and cortex, a subject who was half-blinded at age 3 years old was subjected into surgery to restore his sight. At first, a few months after surgery, the subject perceived slight changes in the orientation common shapes, identified colors and his equiluminance settings were normal. 4 However, the subject has difficulty with 3D stimuli â€" which, as discussed extensively in various psychological studies, is a perception that most human beings are gifted with as compared with most animals. There were numerous other defects noted. In another study, by RA Jacobs, it was discovered that a variety of factors seems to affect learning, including the number of perceptual dimensions relevant to the task, external noise, familiarity, and task complexity. 5Warren G. Darling and Robert Bartelt, in their study o n the visual perception coordinate system using axes defined by the Earth, trunk, and vision, it was concluded that the visual perceptual coordinate system uses internally specified vertical and, when ___________________3 Introduction to Sensation and Perception, AllPsych and Heather Media Group, March 21, 2004, http: //allpsych. com/psychology101/perception. html.
