The Anchoring Theory Of Lightness Perception

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.

Color is determined by the lengths of waves of light. Although there is no sure way to fully tell how we actually perceive color, there are two theories that seek to explain so. One is the trichromatic and the other opponent-process. Whereas one theory lacks in explaining a key problem the other succeeds, which is the case of the trichromatic theory and afterimages. Although the trichromatic theory does not explain the phenomenon of afterimages, of the two theories, the trichromatic one best explains how we see color.

He says that even a minimal amount of bottom up data can produce detailed hypothesises, which is shown in Johansson's study in 1975, whereby in darkness, just a few lights attached to a moving person evoke clear perceptions of people walking or dancing. However, Gregory's theory is questioned by many. For example, if perception is essentially constructive, then how does it gets started and why is there such commonality among the perceptions of different people, all of whom have had to construct their own idiosyncratic worlds. Also, given that perception is typically accurate, it seems unlikely that our retinal images are really as ambiguous and lacking in detail as Gregory suggests.

Steinbeck uses light imagery by saying the quote(pg.38)”Instantly the table was brilliant with light, and of the shade threw its brightness straight downward, leaving the corners of the bunkhouse still in dusk”. This quote shows visual imagery because it represents light being shown on a table and some of the light going downward. It shows a scene of foreboding because it says corners of dusk representing darkness meaning later in the book something bad will happen. Steinbeck represents dark imagery in this quote (pg.44) He walked to the other end of the bunkhouse and turned on the second light. “Darker’n hell in here”. This quote represents kinetic imagery because it represents Carson walking. It represents tactile imagery because it is touching

Color vision is an evolutionary trait that provides primates with significant reproductive and survival value (Gomes, Pessoa, Suganuma, Tomaz, & Pessoa, 2002). However, the quantity and quality of color vision varies within and between species in the primate lineage. Primates are divided into four groups Apes, New World, Old World, and Prosimians. The New World primates are located in the rainforests of South America and surrounding areas, while the other groups of primates are distributed across Africa and Asia (Regan et al., 2005). The vast range of geographical locations inhabited by primates provide images of food requirements that vary dramatically based on environmental conditions.

In the novella Kitchen, Banana Yoshimoto uses light and dark imagery to develop realistic characterization and to support her fantastical style, while effectively projecting pathos upon the readers. Throughout the story, Mikage unveils that life is a process of healing where grief and sadness are needed to truly appreciate happiness. Such abstract ideas and emotions are detailedly brought about by Yoshimoto’s usage of the four seasons of the year to provide a main timeline of the events concerning Mikage’s encounters with death, as well utilizing cosmos as a form of pathetic fallacy during the more miniscule experiences. In the grand scheme of the story, there

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

Bram Stoker utilizes point of view, imagery, and tone to illustrate Lucy’s pre-transformative phase through a diary entry, giving further context to various symbols in Chapter 11 of Dracula.

Also, the findings were consistent with the suggestion that ‘the equal salience of the local and global targets increase sensitivity of stimuli to the effects of how we perceive’ Yovel (2001) cited in Ness et al. (2014).

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

Firstly, an article that relates to my racial identity is called “Yearning For Lightness, Transnational Circuits in the Marketing and Consumption of Skin Lighteners.” This article was written by Evelyn Nakano Glenn. The purpose of this article was to examine the cultural and traditional boundaries associated with the profitable growth and large consumption of skin-lightning products across the world. Additionally, author Glenn focused on the practice of skin-lightness and the marketing of skin-lightning products within the African and African-American cultures (Glenn, 282). Findings from this article indicated that skin-lightning practices can be justified as a form of discrimination against people of dark skin color. In other words, skin bleaching

This explains why in low lights, such as moonlight, everything appears gray. As Rainwater said “By definition, color includes all aspects of light except variations in time and space.” (98) So color and light go hand in hand with each other “The color you see depends on the intensity and wavelengths of the light that illuminates the object, on the wavelengths of light reflected or transmitted by the object, on the color of the surrounding objects, and on absorption or reflection by substances in the light path” (Rainwater 99) Hue, saturation and brightness refer to the aspects of color. “Hue is the color sensation by which you distinguish the different parts of the spectrum- red, blue, green, yellow, etc.” (Rainwater 101) Saturation appears as the degree of hue in a color. “It is the color sensation by which you distinguish a hue as being pale or rich, weak or strong.” (Rainwater 102) Another one, brightness “Brightness is the primary visual sensation by which you detect the presence of light. It is associated with the quantity of the light and the intensity of the visual sensation.” (Rainwater 103) These refer to just some of the terms associated with color and the human

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

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.
