Why Do we have Two Eyes rather than one? Essay

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.

Throughout history, a human being was always reliant on the primary sensory areas. An ability to communicate and contract languages is considered to be a unique ability of human nation as no other species show an equal amount of complexity in terms of the structure and sound combination. On the other hand, primary visual cortex provides a skill set in order to identify the objects presented in the world, the distance towards them as well as to design a set of actions in order to incorporate some items such as a stone or a pen. The understanding of these systems is crucial, especially for those who suffer from strokes and tumors and as a result lost the ability to visually recognize objects or hear other people. This work will focus of the structure

The way we perceive objects depends on different things. One thing that changes the way we view things is monocular depth cues. Monocular depth cues are cues on depth perception that are accessible only to one eye at a time. There are actually a couple of different monocular depth cues. The ones that I will cover will be size constancy, aerial perspective, linear perspective, and texture gradient. Size constancy refers to the tendency to perceive an object or objects as the same size regardless of it being near or far. For example, the imagineers at Walt Disney World use this with their Christmas tree to make it appear bigger. At the bottom of the tree, they place ornaments that are huge. Since people see the huge ornaments at the bottom of

There are many ways one can see and understand the world. The way that the school system authorized us to see and understand the world is through a western perspective. However, there is another perspective that we should all see and understand the world as since we live on the unceded territories; we should all see the world an Indigenous perspective too. This concept of two-eyed seeing is introduced by Mi’kmaw Elders Albert and Murdena Marshall from Eskasoni, a First Nation in Cape Breton, Nova Scotia (Martin, D. 2012, p. 31). The concept is specifically introduced and applied to research in science. However, I believe that this concept can be applied to life in general and in the classroom environment.

One frame from each camera is pulled into the program and then rectified based on calibration of each camera. The calibration process takes in the camera calibration parameters of the cameras, the rotation, and translation of the second camera in relation to the first camera. After being rectified based on the calibration, a disparity map is created. A disparity map is an intensity map that shows the measurements of

Numerous researches and experiments have been done based on whether the human being possess one brain divided into two parts (left and right hemisphere) or whether we have two different brains working together. The psychologist Roger W. Sperry was the first on research this topic with some experiments on animals. Then, he later started working with Michael Gazzaniga. They were able to find split-brain patients. Those patients had their brain split as way of reducing or stopping uncontrollable epilepsy. Many agreed to participate in the experiments. The experiments that they held focused on finding out what kind of limitations would each brain have if they operated independently, how the 5 senses

Humans have a unique and wonderful device in how one sees. The eye and brain work together to turn the world into visual data one’s brain can understand and use. There are some eye conditions that inhibit the sight or the recognition of the shapes one sees. Research continues to overcome these conditions as well as to further understand the biochemical reaction that gives humans the sight and understanding one has of visual data. Included in the paper are some of the latest research methods.

The visual cliff study showed that humans are not born with the ability to discriminate depth perception and we usually develop this ability during infancy. A visual cliff was created using a big glass table that was raised about a foot off the floor. Even though the glass table extends all the way across, the placement of the checker pattern on the floor creates the illusion of a sudden drop-off. The results showed that 3 crawled all the way to the other side to reach their mothers but the remaining 24 cried because they could not

The two independent variables were luminant cue patches (light cue, dark cue and equiluminant cue) and location of the cue and target (valid side with cue and target on same side and invalid side with cue and target on opposite sides). The dependent variable was participants’ reaction time in millisecond.

Vision is the most important sensory compared to other sensory modality therefore there is a wide range of research carried out on vision. Visual attention is defined as a term that portrays how individuals are able to change their view while attending to an image that is of a normal perspective due to the neurones in the cortex (Carasco, 2011). It is often described as a focal point which is situated with different locations in the region of space (Wright, 1998). Visual search requires detecting a specific target as quickly as possible. For example, trying to find your car in a large car park. By focusing our attention to the specific environment it improves our visual search of the target (Keane et al., 2015). The speed of a visual search

Our eyes are vital organs because they help us visualize our surroundings. But are our eyes perfect in seeing what’s right in front of us? Sadly I learned in our evolution, nature messed up at one point and gave us blind spots in our eyes. This project shows why we have these blind spots, how to discover them, and how big they are. I researched on how our eyes see things; why when one eye is closed, the other eye sometimes can’t see what’s in front of it. I also found during my research a formula that is used to estimate the size of a human eye’s blind spot. I performed an experiment using Blind Spot Test card I made to verify the existence of blind spots in my eyes. I also collected data

Compare and contrast Marr and Nishihara’s and Biederman’s theories of object recognition. How well do they explain how we are able to recognize three dimensional objects despite changes in viewing angle?

Buckingham, Milne, Byrne and Goodale’s article, published in the eminent journal ‘Psychological Science’, focuses on the ability of echolocation and the credibility of it obtaining a ‘sensory substitution’ status. What comes with such a status, includes the testing of falling into perceptual ‘traps’. In this research, the authors are interested in whether echolocation, and its users, commit the ‘Size-Weight Illusion’. This is a visual perception trap whereby the perception of an object’s characteristics (size) can be influenced by its appearance (Charpentier, 1891). This notion is aptly condensed into an informative title “The Size-Weight Illusion induced through Human Echolocation” (p. 237).

We see things with our eyes through different visual cues this is called “Depth Perception”. “Depth perception is the use of two different types of visual cues to perceive depth, Binocular cues and Monocular cues” (Department of Psychology,2015). “Depth perception lets us view items in three dimensions and the distance of items. We use several cues to perceive the distance (or depth) of the objects from us and from each other” (Department of Psychology,2015). Goldstein (1984) stated that Cues for seeing depth come from binocular disparity, and also from a range of monocular cues such as motion parallax, linear perspective, relative size, interposition, relative height, and texture gradients.
