Discuss Gregory’s theory of perception
Gregory’s theory of perception consists of a proposal which suggests that formation of incorrect hypotheses will lead to errors in perception. Perception involves making inferences about what we perceive through prior knowledge, past experiences, sensory data and internal hypotheses which play a major part in explaining perception. Gregory adds that an individual’s external and internal factors are determined by expectations, emotion and motives, and so enables two separate individual’s to perception of the same object differently. For example if a hungry person is observing a picture of a dinner table with a bowl of fruit on it, the observer may focus more upon the fruit than other details within the picture. However, Gregory goes on to explain that these factors which can affect perception sometimes cause people to have a wrong perception of an object, predicting that once the perceptual information reaches the eyes 90% is lost by the time it reaches the brain. This occurs due to information being lost through the visual system, as well as the brain letting go of any unnecessary information.
Gregory used the Hollow-Face illusion (also known as Hollow-Mask illusion) as an example of an optical illusion to explain how expectations can affect how we perceive objects. In this case how the observer perceives a concave mask of a face which appears as a normal convex face. While a convex face will appear to look in a single direction, and a flat face which can appear to follow the moving viewer, a hollow face can appear to move its eyes faster than the viewer: looking forward when the viewer is directly ahead, but looking at an extreme angle when the viewer is only at a moderate angle. According to Richard Gregory this illusion shows the strong visual bias for the participants favouring to see a hollow mask as a normal convex face. This is a key example of how perception can act as a top-down process for visual knowledge. This bias of seeing faces as convex which the

    Understanding this factor is crucial to improve one’s comprehension of how perception operates when viewing an assortment of stimuli. Nonetheless, Clarks article opens the reader’s mind to ideas about reality by giving examples of viewing life from different viewpoints. As Clark writes, “Depending on how adept you are at focusing your concentration, you may notice a slight shift in your perception – a weird jump in realty, where you are suddenly viewing the world from a different perspective” (Clark par. 1). By allowing individuals to think from a different perspective, they can shift their perception into grander…

    Perception is the process by which the individual selects, organizes, interprets and responds to information (Hellriegel & Slocum, 2011). Employees are constantly exposed to a variety of information, whether from personal experience or from co workers. However this information is obtained, this information is processed in their minds and organized to form concepts pertaining to what is sensed or experienced.

    Tim Crane claims that the usual, instinctual way of regarding perception is as an “openness to the world.” However, the fact that illusions and hallucinations can occur seems to indicate some sort of fault with the typical view, as these bizarre experiences give rise to questions about the nature and coherence of perception. He asserts that in order to escape this problem, philosophers must provide a theory of perception which both maintains integrity to our intuitions and explains how perceptual mistakes are possible. (Crane 1.1) Peter Strawson in his paper “Perception and Its Objects” describes common-sense realism, which he takes to be an explication of our ordinary view of perception, and attempts to resolve the apparent conflict between…

    In these two stories you see both women being stereotyped. Christa Kilvington being stereotyped for being on government well fare. I can see why people would use that stereotype on her. A lot of the people see using the well fare system are dead beats so to speak, people that are too lazy or on drugs to go find a decent job. With Carol Paik she keeps getting the Asian stereotype where people think she looks like other Asians. I also can understand how people can make this mistake; I think every single one of us will admit that all Asian people look kind of similar and that we’ve each made the same mistake as the people in this story are making with Carol. I personally have made this mistake, even carol made it and she used to complain about people doing the same thing to her.…

    Three reasons for believing in the accuracy or inaccuracy of sensory information is perception, interpretation, and knowledge. Perception is our sensory experience of the world around us and involves both the recognition of environmental stimuli and actions in response to these stimuli (Bagley, 2004). Through the perceptual process, we gain information about properties and elements of the environment that are critical to our survival. Perception not only creates our experience of the world around us, and it also allows us to act within our environment. Interpretation is a communication process, designed to reveal meanings, and relationships of our cultural and natural heritage, through involvement with objects, artifacts, landscapes and sites. Interpretation is how we perceive certain situations through our own thoughts and beliefs.…

    “Perception is the result of the processes of selection, organization, and interpretation of information collected through the senses. Perception involves using what one sees, hears, tastes, smells, and feels to derive meaning from the environment and experiences. Whether done consciously or unconsciously, perception is a fundamental component of communication.”(Alberts, 2009) While doing my interview I started off by giving this definition of perception, just to let her know what was expected for her to look at, in general the big picture. I decided to interview my boss, Veronica Munguia, because I believe that she can pretty much answer to all the questions truthfully and is not afraid of telling me in what areas I need to work on. For the first ten questions she answered almost always, in my job it is expected for me to show what we call six dollar service. Which means that we have to offer; friendly greeting, smiles, show respect, give eye contact, and let our gust express their selves if they are not satisfied. She states that most of this is very natural to my person and doesn’t have to worry much about not letting our guest feel satisfied when they come to our restaurant.…
