The Size Weight Illusion Induced Through Human Echolocation

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

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.

ABSTRACT: The aim of this paper is to defend a broad concept of visual perception, according to which it is a sufficient condition for visual perception that subjects receive visual information in a way which enables them to give reliably correct answers about the objects presented to them. According to this view, blindsight, non-epistemic seeing, and conscious visual experience count as proper types of visual perception. This leads to two consequences concerning the role of the phenomenal qualities of visual experiences. First, phenomenal qualities are not necessary in order to see something, because in the case of blindsight, subjects can see objects without experiences phenomenal

While the obese man flailing is the center of the shot, it is WALL-E’s reaction that draws attention from the audience, as he is stunned by the man’s incapability to stand up. The fast-paced moving of the levitating chair network represents the action and intensity of the scene and impacts the viewing audience by raising their heart rate. The sound effects of the scene—whether it be dialing on a phone, the sound of a levitating chairs passing, computer

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

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

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 purpose of this essay is to examine the article " The Fat-Brain Axis Enters a New Dimension," by Joel Elmquist and Jeffery Flier. This essay will attempt to explain this article and summarize its key points.

Research Essay: “The Tell-Tale Heart” by Edgar Allen Poe “The Tell-Tale Heart,” by Edgar Allen Poe, is a story of a nauseating death. Murder as an upshot of an eye; literally. Incongruous actions are taken by Poe when he determines the fate of a man he claims love upon, all because “He had the eye of a vulture” (Poe), and Poe plots the death of this old man. As noted in Short Story Criticism, it’s stated that; What precipitated the narrator’s insanity and the subsequent murder was his irrational obsession with the old man’s so called “Evil Eye.” The narrator freely admits to his auditors that this was his Primmum mobile: “yes, it was this!

Among those in support of the claim that change blindness and inattentional blindness reveal a grand illusion of visual perception, Cohen identifies three interpretations of the illusory beliefs in which the grand illusion is understood: world richness, representational richness, and representational reality. Although Cohen forms arguments against each interpretation of illusory beliefs, as stated earlier, this paper will focus on the idea of the grand illusion in regards to the illusory belief of representational

“We believe we’re seeing the world just fine until it’s called to our attention that we’re not.” (Eagleman, 2011) This caught my attention as I began to wonder what in the visual world my eyes missed. Optical illusions are only possible because of the fact the brain skips over the information not deemed necessary, creating illusions of color, movement, or any other desired affect of the illusion. The data the brain receives through any of the senses has to be processed, a process usually mastered shortly after birth.

Cornell University did an experiment with a setup that they called a “visual cliff.” The “visual cliff” was made of a board laid across a large sheet of heavy glass. They put a patterned sheet right up against the glass on one side and left it lower on the other side. This was used to test the behavior of infants and young animals. The psychological concept in this paper was to see if young children and animals are aware of height perception. They found out that most human infants can discriminate depth as soon as they can crawl. The experiments were done to see if infants and young animals were born with depth perception or when they could visually predict the depth of different things. By creating the “visual cliff’ and setting babies and animals on it.They were able to study the behavior and see if they prefered the shallow side or the deep side. Toward the end of the paper they were doing experiments to see if animals reared in the dark at an early age. They wondered if this would change depth perception of rats and kittens, but it really did not have an affect. From the work from the visual cliff they are concluding that a seeing animal will be able to discriminate depth when they are able to move around at a young age. The results of this experiment has shown that through our own visual cues we are able to determine the height of our

Ventriloquism suggests that as our perception of the location of sound changes, the actual physical origin does not (Choe, Welch, Gilford, & Juola, 1975). Its effects are shown as sounds are deemed to be coming from a different direction due to the perceiver being influenced by visual stimuli (Sharma, & Smith, 1987). This effect is exploited by stage ventriloquists who manipulate the movements of a puppet or dummy whilst speaking without moving their mouths (Pages, & Groh,

Obesity is a common phenomenon across the world where, in particular the United States, more than two thirds of adults, over the age of twenty are considered to be obese. As a result, one of the major topics in social media to date is body image and what society perceives as the ideal physique and as overweight or obese. In most cases society tends to favor a thinner and leaner physique over those carrying a few extra pounds of fat, who are immediately characterized as obese people. Though there is plenty scholarly discussion sounding dire warnings of the rising obesity epidemic, exaggerating the risks of phenomenon may lead society to attribute meaning to obesity that goes beyond the actual pathology in association and fail to acknowledge the reality of the condition. Obesity is a direct consequence of one’s lifestyle habits. My main focus is to
