Reflection on Visual Perception Introduction Visual perception is the ability to absorb and internalize ones surroundings by analyzing information using light that can be seen by the eyesight. Therefore, visual perception in short is the ability to see things using an individual’s eye. This article is going to analyze the role of the visual cortex in visual perception.
Visual awareness is controlled by nerve cells. However, there is dissociation between visual awareness and visually guided behavior. An example is with people with blind sight. These patients do not apprehend visual stimuli and other Visuo-motor behavior yet are very aware of various stimulus characteristics. Therefore, this means that visual guided behavior does not have to be conscious (Lamme, 2000).
In the search of the role of the visual cortex in visual awareness, data taken from visual cortex (v1) recordings of monkeys show two types of visual awareness (Lamme, 2000). First data shows that visual awareness in monkeys that are awake is guided by a set of neurons. This means that the visual cortex does little in providing visual awareness. The second data shows the visual cortex does not relay the images upon perception but that visual awareness comes as a result of a horizontal flow of neurons. This means that visual awareness is not solely because of the visual cortex and visual awareness does not come from a particular cell (Lamme, 2000).
In the test done, two different recordings are found. Therefore, it has been found that visual cortex does not mirror perception but horizontal flow of neurons does. Moreover, all visual awareness is not conscious. Despite these facts, the neurons produced by the visual cortex transform perceptual impression which in turn adjusts visual organization, awareness and attention.

The pilot now stepped into a world of change and challenges that had to be...

Visual perception issues involved in traffic accidents

...Visual Perception Visual perception is one of the senses, consisting of the ability to perceive light and construe it as the perception known as sight (Wikipedia). Vision has a specific sensory system. How the brain perceives what the eyes see is perception by means of the eyes. Our sense of sight or vision gives us the required hints to gauge the limits of our spatial surroundings, near and far, making sense of all the objects in it to our consciousness. What we see is an illusion which is inside us, but all of us share the same internal perception of a real and physical universe outside us. The sense is so well adapted...

Visual Perception

...Of all human senses, vision is probably the most complex, and this complexity can only be matched by the complexity of the eye as the organ that provides sight. This complexity however, allows for a variety of pathologies to appear, some of which are treatable, and others representing a serious disability. 1. One of the most common pathological states concerned with visual acuity in vision is myopia or nearsightedness. In this disease, the axis of the eye bulb, or axis bulbi is longer in relation with the eye's ability to bend light, therefore people that have myopia see clearly only in the area limited by the punctum remotum (the farthest point that is clearly visible) and punctum proximum (the closest point clearly visible... of the...

Visual Perception (Psycology 101)

...Visual Perception Visual perception is basically the perception that is dependent on one’s vision. It takes into consideration the usage of the eyes which see the light and thus interpret the viewed object to the brain. Thus the whole perception is built as a result. This perception is thus called as the eyesight or in more common terms as the naked eye vision. Vision is composed of the sensory system which is the visual system in essence. One of the biggest problems related with visual perception lies in the fact that the objects which people see through their eyes is...

The Cognitive Basis of Visual Object Perception

...The Cognitive Basis of Visual Object Perception INTRODUCTION Visual perception, particularly the recognition of objects is an immediate but complex process. Objects are defined as solid bodies of substance which show “spacio-temporal continuity, cohere within their boundaries when they move, and move only when contacted by other object” (Spelke et al 1995, p.169). According to perception psychologists, object perception is a broad as well as narrow term in the field of vision and cognition. Broadly, the term is applicable to both animate and inanimate objects, and includes: a combination of elements within and a uniting of...

Nature, perception, reflection and conservation

...NATURE, PERCEPTION, REFLECTION AND CONSERVATION The writing of John Muir and Susan Sontag are both essays but not stories. Both writers have spent their time trying to give vivid descriptions of their stories. As one reads through the two stories, he or she becomes lively and wishes to lead more about the nature of the forest, and the photography respectively. The two essays have come out to be very similar in many ways. Firstly, the writer of “a wind storm in the forest” uses a lot of imagery in his writing. This imagery gives a lively image of the forest and the tree, in the ways they respond to the wind (Teale 53). Similarly, Susan Sontag has used imagery throughout his writing to describe the war and...
