Perception is the mental process we use to become aware of impressions of others and of ourselves (About.com). It helps us use to our senses to interact with our surroundings. Our perception relies on nine parts of the ear and on thirty parts of the eye. These parts work together in our daily functions. In order to function best, a person needs the senses of hearing and sight. When one of these parts does not work, it causes disruption in a person’s daily life. Both the auditory and optical systems work independently; however, they coordinate to enable the brain to respond to sight and sound. Sight and sound processing is critical to a person’s ability to function independently in society. This paper, will explain how we see and hear, and how vision and hearing connect to psychology. The eye has particular responsibilities in vision. How we see depends upon the transfer of light. Light passes through the front of the eye through the cornea to the lens. The cornea and the lens focus the light rays onto the back of the eye to the retina. The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain. The eye works much the same as a camera. The shutter of a camera can close or open depending upon the amount of light needed to expose the film in the back of the camera (n.d. - how it works and anatomy: University of Michigan Kellogg Eye Center). The eye, like the camera shutter, operates in the same way. The iris and the pupil control how much light to let into the back of the eye. When it is very dark, our pupils are very large, letting in more light. The lens of a camera is able to focus on objects far away and up close with the help of mirrors a... ... middle of paper ... ... us. The occipital lobe is located at the back portion of the brain and is associated with interpreting visual stimuli and information. The primary visual cortex, which receives and interprets information from the retinas of the eyes, is located in the occipital lobe. Damage to this lobe can cause visual problems such as difficulty recognizing objects, an inability to identify colors, and trouble recognizing words. (Robinson, 1994) When sight and hearing do not work, it causes disruption in a person’s daily life. Both the auditory and optical systems work independently; however, it does explain how the brain responds to sight and sound. Indivuials cannot function without these two perceptions. Without sight, we would not be able to make our own judgments and impressions, and, without hearing, we would not be able to refine our original judgments and impressions.
