Perspectivist Optics

While implementing Primary Health Care models, identical to those in metropolitan areas, in a rural setting is not practical, I feel there is an obvious need to improve primary health care in remote areas. This is due to the significant health gap between Indigenous and non-Indigenous Australians, in rural and remote areas

She discusses those who have recently acquired the ability to see and how this affects how they interpret the new world around them. With no preconceived knowledge or ideas about what they are seeing, “vision is pure sensation unencumbered by meaning” (24). While our minds use what we already know to interpret and comprehend what we see, those who see for the first time have no previous knowledge telling them what they are looking at. Their minds are blank canvases, interpreting each line, shape, and shadow, attempting to piece every aspect of what their eyes are seeing to understand the full picture. While we would simply glance at an object, allowing our mind to fill in the details of what we are seeing based on the image we already have in our minds, the newly sighted do not have the ability to see in concepts as we do. Most of us cannot “remember ever having seen without understanding” (27) yet we still have the ability to learn how to see like this to an extent. Artistic talent aside, upon asking a newly sighted person and an artistically untrained person who had been seeing their whole life to draw the same object, the newly sighted person would have the ability to draw what they were truly seeing while the average person would draw what they knew they were seeing, ignoring the true shape and shadows of the object in front of them. Upon asking someone who has been trained

Since he saw no oscillation throughout his experiments he believed that light could only be a particle. This theory was supported by lights rectilinear propagation. A simple experiment

The first thing that I learned about perception was earlier discovered by a psychologist by the name of Max Wertheimer. He discovered that our body clearly separates images into figures

My decision to pursue a degree in optometry started from an unlikely source within the field of healthcare. I originally aspired to become a pharmacist and had extensive experience as a pharmacy technician throughout high school and the start of college. As I progressed I became more unsure of the profession, and did not feel as though as if I was making a difference. Patient interaction was minimal and I felt that having a more personable connection would make for a better healthcare professional. I always knew I wanted to become a healthcare professional, I just was not sure pharmacy was the path for me.

The visual perception field is a very old are of study in psychological research. From ancient Greece to modern day scholars, philospher and psychologists have been studying on visual perception for centruries. As a result of people studying visual perception for such a lengthy amount of time, ground breaking researches have been conducted by many observers like Emil Emmert. In1881 it was found by Emil Emmert that an objects size afterimage seems to vary in size based on whether it is positioned close or farther away. When near by the object looks small. And the farther away it gets, the size of the object becomes noticeably larger. It’s perceived size is thought to be fixed on the retina and as it increases the perceived distance is also thought to increase consecutively. This

This question defines the nature of Aristotle’s inquiries, at least for a large part of the Metaphysics, and it thus offers a fourth account of the study or science of metaphysics.“The science of first principles, the study of being qua being, theology, the investigation into substance – four compatible descriptions of the same discipline? Perhaps there is no one discipline which can be identified as Aristotelian Metaphysics? And perhaps this thought should not disturb us: we need only recall that the metaphysics was composed by Andronicus rather than by Aristotle. But the four descriptions do have at least one thing in common: they are dark and obscure” (Ross, 1996, p174).

After investigating spatial cognition and the construction of cognitive maps in my previous paper, "Where Am I Going? Where Have I Been: Spatial Cognition and Navigation", and growing in my comprehension of the more complex elements of the nervous system, the development of an informed discussion of human perception has become possible. The formation of cognitive maps, which serve as internal representations of the world, are dependent upon the human capacities for vision and visual perception (1). The objects introduced into the field of vision are translated into electrical messages, which activate the neurons of the retina. The resultant retinal message is organized into several forms of sensation and is

It has been a common assumption that “seeing” comes from the ability of one’s eye to

The memoir, Traveling Blind: Life Lessons from Unlikely Teachers, details the life of Laura Fogg. Although initially studying to become an Art Historian, Fogg radically changed career paths after witnessing an orientation and mobility instructor at the California School for the Blind. Although beginning as a curiosity, this interaction led to Fogg’s pursuance of a Masters in Orientation and Mobility at San Francisco State College, and eventually a thirty year career as a Orientation and Mobility Specialist in rural Mendocino. The memoir, Traveling Blind: Life Lessons from Unlikely Teachers, details Fogg’s experiences as a teacher of the visually impaired, and provides the reader a glimpse into the challenges and successes of her work. In each chapter, Fogg highlights a separate student who has someway or another changed her life. From the zany Shaynna, to the humorous Red, Fogg illustrates the uniqueness of each of her students. Although, Traveling Blind: Life Lessons from Unlikely Teachers, explores the lives of Fogg and her students, the memoir also serves as an illustration on the meaning of patience, loss and humanity.

from what he call[ed] the haptic objectivism of the Greeks—the delineation of the clarity of the object through an appeal to and a stimulation of the tactile associations of the viewer—to the optical objectivism of Roman art, in which the need to set the figure up in space as radically

Three throries floated around in the 17th century. The first suggested that the eye sent out something which then registered the world around it. The second advocated that objects emitted something which hit the eye. The third adviesed that a medium between the eye and the environment around it changed between the object and the eye which allowed for sight. Based on the third theory, Christiaan stated that light travled through a recherché substance called luminiferous ether. Supposedly, the waves vibrated the ether as they traveled form the pobject to the eye. With this as his hypothosis, Christiaan founded the lwas of reflection and refraction. Although his calculations remain correct, no such ether exists. His theory was quickly rejected by his college Isaac Newton, who believed that light is composed of several small bodies moving. Today, light is known to have attributes of both particles and

A perceptual set refers to a susceptibility to perceive things in a certain way. In other words, we often tend to notice only certain aspects of a object or situation while ignoring other details. In psychology a perceptual set is basically a tendency to view things only in a certain way. Perceptual sets can impact how we interpret and respond to the world around us and can be influenced by a number of different factors. Such as: your own past experiences, expectations, motivations, beliefs, emotions, and even culture. Past experience/ expectation plays a huge role in perception as how you recognise something can be due to previous exposure. For example the experiment (Rat-Man). Participants were shown either several pictures of animals or of people prior to being shown the ambiguous figure.

The nature of light has been the subject of contentious scientific scrutiny for most of recorded scientific history. At the heart of that scrutiny was a debate over the fundamental properties of light: is light a wave or a particle? Ancient scientists like Euclid of Alexandria and Ptolemy of Rome conducted rudimentary experiments exploring the tendency of light to reflect off of smooth surfaces or refract when passing through a medium. These were the first indications of light’s wave properties. Ultimately, this wave theory of light was insufficient in explaining all of light’s phenomena; for example, when light encounters a corner, it will cast a shadow rather than bend around the corner like waves of sound--thus the debate continued. The work of an Italian physicist, Francessco

Light, a concept that has been worked with for many years dating back to 500 B.C. Pythagoras hypothesized that humans perceive light due to the human eyes ability to emit rays upon the environment and the emittance gives a human his or her sight (Sekuler). Afterward, human intellectuals started making it more concise to present day knowledge of light. This development of light came from two intellectuals named Christian Huygens and Isaac Newton. Newton exclaimed during the 1700s that light was a stream of particles carrying energy but Huygens, Newton’s contemporary, thought that light needed this invisible “ether” in order for these streams to make light travel. Then, a couple hundred years later, modern scientists such as Albert Einstein, Thomas Young, and Augustin Fresnel proved Isaac’s and Huygens’ hypotheses of light (Rossing, 23-24). This is how the basis of light was created.
