Inattentional Blindness Essay

752 Words4 Pages

When it comes to perception of the world, every individual’s view of the world is highly subjective. In this essay, I will explore the theories of sensory adaptation, inattentional blindness and perceptual constancies, and how they collectively vary the perception of outside stimuli from one individual to another. Exposure to certain stimuli for a relatively long period of time may lead to sensory adaption. Sensory adaptation occurs when the responsiveness to a stimulus reduces as the exposure to the stimuli becomes constant and prolonged. In layman terms, the sensory receptors “gets used to” the stimulus and stops significantly reacting to that particular constant stimuli. Aside from the constancy in the sensory input, any changes in incoming stimuli, for example, a loud crash in prolonged silence, or a flash of lightning in the dark night, would stand out. In other words, sensory adaptation keeps people tuned in to the changes rather than the constants in their sensory input (Weiten, W., 2002). An example would be enjoying natural hot springs. The first step in the hot spring water would feel like a scald, and …show more content…

In a study conducted to test the theory of inattentional blindness, research participants were asked to focus on three black-shirt-clad basketballers, and count the number of times the ball was passed. Midway through, a gorilla enters the scene and had a total screen time of nine seconds. Despite being conspicuous and in plain sight, 46% of research participants failed to notice the gorilla’s appearance. In the duration of the experiment, the participants focus was on the basketballers and as a result, the occurrence of inattentional blindness caused them to be unaware of the unexpected appearance of the gorilla in the scene. (Simons, Daniel J., and Christopher F. Chabris,

In the article The Cost of Paying Attention, the author, Matthew B. Crawford shares his revelation that individuals are constantly surrounded by advertisements. He starts by sharing an instance where he saw advertisements as he was checking out at a grocery store and then claims that they constantly steal consumers limited attention there by taking away our ability to dwell in silence or without the advertisements.

In Ralph Ellisons’ novel, “The Invisible Man”, the protagonist, whose name is never revealed, perceives himself to be invisible in a literal and figurative sense. The context of the novel focuses on a black man, who was forced to adapt to a white Western environment as he increasingly succumbs to the idea that he is invisible. There is a sense that his black skin makes him appear more visible but also erases him from the white Western environment. He perceives himself, in light of Franz Fanon’s “Black Skin White Masks” only through the eyes of the white Other. This idea of “double blindness” runs through the entire novel and displays the extent to which protagonist is blinded by his reality to the extent that he perceives himself as invisible.

All amazing on their own, but when all are working independently of each other properly people can function pretty well. However, when the slightest disruption interferes with how our senses work properly life can become pretty unbearable at times. Just to name a few issues such as the common cold, seasonal allergies, conjunctivitis, and ear infections can very easily cause the balanced system to go out of whack.

It is a lack of clarity that creates chaos. The chaos in Shakespeare 's King Lear is due in part to Lear 's inability to see the true nature of situations going on around him.

When a person ponders the state of blindness, the first thought is usually the impairment of a person’s eyes or the loss of physical vision. However, those who can physically see may possess more blindness than those without sight. In Raymond Carver’s Cathedral, Robert is a blind man who shows the narrator how to look beyond his physical sight and truly “see.” Through interaction with him, Robert instructs the narrator to observe beyond the exterior of a person so as to recognize inner beauty.

Introduction According to information processing model, short term memory has a limited capacity to hold information (Atkinson & Shriffin, 1968). The span of short term memory is said to be limited to about seven items (+2) (Miller, 1956 as cited in Terry, 2000). Short-term memory is also an active memory where we do our active memory processing (Lefrancois, 2000). For this reason, several researches have called the short term memory the working memory store (Gordon, 1989).

This essay will discuss the statement by William James, “-whilst part of what we perceive comes through our senses but another part (and it may be the larger part) always comes out of our head.” (James, 1890). This excerpt relates to the topic of perception, which can be defined as the acquisition and processing of sensory information to see, hear, taste, or feel objects, whilst guiding an organism’s actions with respect to those objects (Sekuler & Blake, 2002). Every theory of perception begins with the question of what features of the surrounding environment can be apprehended through direct pickup (Runeson et al. 2000). Is it only vague elemental cues that are available, and development and expansion through cognitive processes is required

In this essay I will write about the strengths and weaknesses of perception as a way of knowing. Perception is the way we perceive the world through our senses. We use all five of our senses, which are sight, hearing, smell, taste and touch to understand the world and interpret it. We can then say it’s a Primary way of knowledge. We can also say that, because the senses is the way our body communicates, we have at least three more senses: kinesthetic sense, which is our awareness of our body’s dimensions and movement; vestibular sense, which is the awareness of the human’s balance and spacial orientation; and organic sense, which is the manifest of the internal organs (for example, hunger or thirst).
