Visual Information Processing
The human brain is capable of perceiving and interpreting information or stimuli received through the sense organs (i.e., eyes, ears, nose, mouth, and skin) (Weiten, 1998). This ability to perceive and interpret stimulus allows the human being to make meaningful sense of the world and environment around them. However, even as the human being is able to perceive and interpret stimuli information through all sense organs, stimuli is most often or primarily interpreted using the visual (eyes) and auditory (ears) sense organs (Anderson, 2009). However, for the purpose of this paper, the visual information process will be examined. Conditions that impair the visual information process will be analyzed, in addition to, an examination of the current trends in research that are advancing the understanding of research of visual information processing.
Understanding Sensation and Perception
To understand better how the brain processes visual information, an understanding of, and a clear differentiation between sensation and perception is required. Before stimuli can be perceived or interpreted, it must first be sensed through the sense. Therefore, sensation is the stimulation of sense organs (i.e., eyes, ears, nose, mouth, and skin) and involves the absorption of energy, such as light and sound waves through the sensory organs, (Weiten, 1998). Perception refers to psychological processes in which the immediate organization and interpretation of sensations are involved (Riegler & Riegler, 2008) and “involves organizing and translating sensory input into something meaningful,” (Weiten, 1998, p. 123). The Visual Processing System
People rely heavily on their sense of sight; it allows them to establish a keen sense of what in their environment is trustworthy, (Weiten, 1998). Consequently, sight is depended upon almost more than any other sense organ. As primates,

    Gibson’s and Gregory’s theories of perception both suggest that eye-retina is important for perception. The both believe that without eye-retina, a person will not be able to see. This is a common view of both of the theories of perception. The idea is supported by the case of SB. SB was a man who had been blind from birth due to cataracts. When he was 52, he had an operation which restored his sight and hence he could see. Thus, this case has shown the importance of eye-retina for things to be perceived. And therefore, supports both of theories of perception which eye-retina is essential for perception.…

    Human eye is made up of complex structures which help us to see the things around us. These structure work together to make an image on our retina. Especially our cones of eye are specializing for the color vision while rods are essential for black and white. On the other hand blind spot is an area in the eye where photoreceptors are not present for the vision. In daily life we do not focus on this aspect and ignore it(Walls, 1954).…

    Why is that we cannot perceive everything what is within the range of our senses? Is it because our capacity is not up to the job or is it because our conscious mind would drift us straight into insanity ? There is no straightforward answer to that. However, it is known that the attention itself is not only the conscious one, but also as it seem sub-conscious one, which is responsible for the automatic interactions with the environment. There is no need to concentrate on breathing or reading at the stage of an healthy adult person. But once those processes were new and there was a time when they were fully conscious. This experiment zooms in on the clash between controlled and automatic attention processing.…

    Object recognition is one of the most essential elements for the survival of all living creatures. Object recognition is considered the determination of the implication of a certain object. Object recognition is imperative given that humans and other living creatures manage to respond to the imperative features of the presented object. Assuming that present information concerning an object appears in two dimensions within the eye retina, there are many possibilities of confusing the same object with another thus substantiating visual recognition. However objects are not colour coded or labelled for us. Many objects look similar and do not contain one identifying mark or viewed in identical conditions. So why do humans have an extraordinary ability to identify a certain object regardless of its disparity in appearance. Additionally, humans can manage to take a broad view through observation of collections of objects that are not familiar. These objects are often identified from different views, vantage points, sizes and locations. Objects can also be distinguished in cases where they have been partly blocked from view. Various object recognition conjectures present the subject through utilization of different perspectives thus, bringing a clear distinction to understand object recognition.…

    Technologic advances afford us a clear understanding of the physiology of sight; incoming light permeates the cornea, which is focused into the retina containing receptor cells called rods and cones. Rods assist vision in low-level light, whilst cones, located primarily in the fovea are responsible for detecting fine detail and colours. The rods and cones are linked to the optic nerve, which send information via the lateral geniculate to the visual cortex. The visual cortex is responsible for processing the incoming visual information (Pike & Edgar, 2010 pp 66 & 94); how this information is then interpreted is what we term perception. Whilst science can implicitly explicate the visual system, visual perception is…

    Although well related, sensation and perception play two complimentary but vastly different roles in how we interpret our world as humans. Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell, also known as the five senses. This information is then sent to our brains in raw form where perception comes into play. Perception is the way we interpret sensations and then make sense of everything surrounding us. Both sensation and perception are simply two terms used to describe how our senses work coherently together to organize and interpret information. Although sensation and perception are used conjointly in processing the world around us, they each have individual processes that together piece together our world almost as you would a jig-saw puzzle.…

    The human eye and brain are two of the most extrodinary and vauleable organs in the body. The eye gives people the ability to perform daily tasks and to explore the world around them. The brain gives people the ability to feel emotions, to reason, and to conform. Vision, is an occuring process that needs constant interactions between the eye, the nervous system, and the brain. When a person looks at an object, they are actually seeing the light the object gives off. This light is passed through the lens, and then passed through the retina of the eye. From there, the light triggers nerve impulses which are then sent to the optic nerve in the brain. In the brain is where that light becomes and image, and depending on prior knowledge or comfortability with that image, our barin will make a hasty judgement. These judgements decide whether we like or dislike a person, race, gender, or anything that physically makes a person who they are.…

    Sensation is the process in which sensory receptors and the nervous system receive and represent stimulus energies from the environment (Myers, 2011). Our sensory receptors include our five senses; touch, taste, sight, sound and smell, and the parts of the body that allow us to do those five things. Perception is the process of organizing and interpreting the sensory information, which makes us recognize objects and events (Myers, 2011). How we take in the information from our sensory receptors and interpret them is our perception. Sensation and perception are connected because without sensation, there is nothing to perceive. We touch with our hands, smell with our noses, without sensations we would not be able to interpret those senses. We need both sensation and perception to interact with the world around us, and in that sense both sensation and perception are related. The two differ in what actions they carry out for us, both basically complete a two-step process. The senses gather information, and the perception interprets it all.…

    Man’s capacity to use his or her visual mechanism places him or her on top of all creatures in the world. There is no doubt that in the list of the basic human senses, vision is number one, followed by audition or hearing, kinesthesia or touch, olfaction or smell and gustation or taste. Authorities state that although man uses all his senses simultaneously in gathering varied stimuli from the environment, nearly eighty percent (80%) of all knowledge and information that man acquires in his or her lifetime are gained through the visual modality. With the use of human intelligence mainly through vision, man has attained superiority over all other species in the world as shown in the tremendous advances in technology through the centuries. A writer poses two questions on how much man values human sight: “Through the centuries, how many have really appreciated God’s greatest gift to man? Even in this day of modern scientific miracles and educational opportunities, how many really know what the eye really is and what makes it work? To which a third question is added, “How much and how well does a man take good care o his/her vision?”…
