Our attention is very selective when it comes to getting information from our environment. We could be looking at everything within our environment and miss changes that occur while looking. According to Rensink, O’Regan and Clark (1997), attention is a key factor, meaning when our attention is focused on the area of change then change can be detected. When we fail to detect change, it can result in change blindness. In support of this idea, Simons and Levin (1998) suggest that change blindness occurs if there is a lack of “precise” visual representation of their surroundings. In other words, a person can be looking at an object and not fully notice a change.
As a result, our attention selection is limited if not directed. Therefore, redirecting

Therefore, the informed group would detect more changes than the uninformed group. This was as a result of their attention being pre-directed to the area of possible change. Our attention is based on a selection. In contrast to not having a focused attention, we can easily miss changes within our environment. Therefore, our hypothesis was supported the informed group was better able to detect changes than uninformed group.
Though the experiment shows that attention is vital for change detection, we should consider the size/ impact of the change in the environment. If the change to an environment is small, would it result in the change being detected? Do providing little clues draw attention effectively to where the change is being made? In support of this argument, Rensink (1997) showed that even with small clues, if the clue is not directed properly then detecting change will not have an effect. A proposal of Rensink is that the absence of attention will cause visual contents to be missed. On the other hand, Simon and Levin (1998) suggest that a person could miss things happening in their environment if his or her attention is occupied by something
A video is put on, and in the beginning of this video your told to count how many times the people in the white shirts pass the ball. By the time the scene is over, most of the people watching the video have a number in their head. What these people missed was the gorilla walking through as they were so focused on counting the number of passes between the white team. Would you have noticed the gorilla? According to Cathy Davidson this is called attention blindness. As said by Davidson, "Attention blindness is the key to everything we do as individuals, from how we work in groups to what we value in our classrooms, at work, and in ourselves (Davidson, 2011, pg.4)." Davidson served as the vice provost for interdisciplinary studies at Duke University helping to create the Program in Science and Information Studies and the Center of Cognitive Neuroscience. She also holds highly distinguished chairs in English and Interdisciplinary Studies at Duke and has written a dozen different books. By the end of the introduction Davidson poses five different questions to the general population. Davidson's questions include, "Where do our patterns of attention come from? How can what we know about attention help us change how we teach and learn? How can the science of attention alter our ideas about how we test and what we measure? How can we work better with others with different skills and expertise in order to see what we're missing in a complicated and interdependent world? How does attention change as we age, and how can understanding the science of attention actually help us along the way? (Davidson, 2011, p.19-20)." Although Davidson hits many good points in Now You See It, overall the book isn't valid. She doesn't exactly provide answers ...
Sense Perception is a way of knowing in which a person can acquire knowledge using their five senses - taste, touch, sight, sound and smell. Sense perception is an important in our understanding of the world, and is a source of much of the pleasure in our lives. But, can we trust our senses to give us the truth? This may come out as an odd question to many because according to experience and history it is known that humans greatly rely on sense perception as a means of survival. However, like all ways of knowing, sense perception has its weakness; our senses can easily be deceived. In his TED Talk, “Are we in control of our decisions?” behavioral economist Dan Ariely uses examples and optical illusions to demonstrate the roles, strengths and limitations of sense perception as a way of knowing.
Processing capacity is a very broad and flexible category according to many researchers. In fact, the quote above mentioned suggests that we often fail to notice things that happen just in front of us (unexpected events that are often salient) either because we were completely absorbed by something else or because we had so many things to do at the same time that we couldn’t pay attention to it. We have all at least once failed to see a friend who was waving at us while eating in the cafeteria or walking in a crowded street. The primary question that we should ask ourselves is: how many things can we attend at the same time? The truth is that we didn’t perceive this friend because of a phenomenon called “inattentional blindness”. The problem is that the richness of our visual experience leads us to believe that our visual representation will include and preserve the same amount of detail (Levin et al 2000). In this paper we’ll see the different theories of inattentional blindness, and the classical theories demonstrating this paradigm.
As a person one might find that we follow a specific routine on the day to day basis. Sudden changes to these routines feels weird and out of place. In William Faulkner’s “A Rose For Emily” based in a fictional town called Jefferson taking place during the twentieth century. The time period is indeed an important factor because southern tradition was above all of the highest importance. This short story gives the audience details of life during that time in which they followed the values of southern tradition and the importance to never stray away from those traditions. The context of the story is laced with subliminal messages of humanities resistance to change.
In “The Anatomy of Judgmen”t, M. L. J. Abercrombie discusses how information is gained through our perception. Abercrombie claims that interpretation is a very complicated task that people have been learning to exercise since birth. Each person has a different way of interpreting the objects or situations they see, because people often relate their own past experiences. She also explains two important concepts: schemata and context. She defines schemata as a way our mind functions by understanding new things perceived through sight, by relating it to an individual’s past experiences. Past experiences help interpret what is seen further, if the object fits one’s expectation or their schemata, and not something different from their past experiences. Her fundamental insight is that seeing is more complex than just passively registering what is seen, and consists of a form judgment for...
many more continuing on to describe a change that did not happen. Change blindness is evident in this example because students were convinced a change occurred, even though they actually never saw one; this is because the brain was focused on too many factors at once to remember everything there was to know about the seemingly insignificant detail of cups. We find it interesting that thirty students answered no, as the trend among students was obviously to assume that every change, true or false, we questioned them about actually happened. We are pleased to see that thirty students trusted their brain and memory enough to answer correctly, or maybe even just guessed right.

In the world of science there are many discoveries. “A discovery is like falling in love and reaching the top of a mountain after a hard climb all in one, an ecstasy not induced by drugs but by the revelation of a face of nature … and that often turns out to be more subtle and wonderful than anyone had imagined.” (Ferdinand Puretz). Most people in the world we live in lack to notice and or appreciate the gift of sight in life. By not cherishing the gift of sight and using it properly, many discoveries are left unfound. In the writing piece, Seeing, Annie Dillard speaks of nature and the small things that we all are unconsciously blind to and not appreciative of. Seeing explores the idea of what it means to truly see things in this world. Annie Dillard’s main point is that we should view the world with less of a meddling eye, so that we are able to capture things that would otherwise go unnoticed. There’s a science to how we view things in nature. Dillard attempts to persuade her reader to adopt to her way of seeing, which is more artificial rather than natural.

The way one views the world around them is a reflection of themselves, as Anais nin clearly stated, “ We see things not as they are but as we are.” perception, the ability to see, hear, or become aware of something through the senses, is a key component to how one lives their life. It is the driving force behind one's reaction to the world around them. Perception has a large influence on how things are interpreted such as emotions and meanings as well as making inferences about others. Perception itself can be influenced by others in one's community or the environment. The way one perceives or is being perceived has an effect on a person's life including one's needs, desires, personality, and experiences.
Perception is defined as the awareness of the world through the use of the five senses, but the concept of perception is often used to isolate one person’s point of view, so how reliable can perception be if no one person’s is exactly the same? The word perception itself is riddled with different, well, perceptions of its meaning. When some hear the word, they might automatically think of it as something innately flawed, that can easily be fooled by illusions, while others may think of its usefulness when avoiding scalding a hand on a hot stove. I am here to agree with both and to argue that perception is something necessary and helpful, and something that should be scrutinized for its flaws. By looking at perception as a way of knowing in the context of memory and human sciences, it can be concluded that perception can contribute to the acquisition of knowledge by constructing a foundation on which incoming stimuli from the environment are able to be quickly interpreted and acted upon, but perception can also hinder the acquisition of knowledge by wrongly interpreting those stimuli, causing inappropriate reactions.
Blindness is a state or condition of being unable to see because of injury, disease, or a congenital condition. In some cases, it is a lack of perception, awareness or judgement. Blind can also be a word to describe ignorance. We are all blind to the world around us. I have learned that it will take time for the film to shy away from our eyes and show us the agony of reality.
Each one of us lives in our own unique world of perception. As individuals, we may experience life in an entirely different way through our senses and life experiences. Therefore, perception can be tricky since it is very personal to each one of us. According to the Merriam-Webster online dictionary, perception has three meanings; (1) “the way you think about or understand someone or something,” (2) “the ability to understand or notice something easily,” and, (3) “the way that you notice or understand something using one of your senses” (2014, para. 1). C.S. Lewis said, “What you see and what you hear depends a great deal on where you are standing. It also depends on what sort of person you are” (n.d., para. 11). In other words,
My whole life, I have been presented to a single element called change. Change occurs in many different forms and is carried out in many different ways. However, just recently, I have come to the realization that change can be the deepest of all subjects. I always assumed that change occured when you moved to a new town or when you lost someone close to you. Those are elements to change, yes, but change doesn't have to occur over a single dramatic event. It can just happen overnight when your brain determines it's time to do something different.
Perception is a mysterious thing; it faces a lot of misconception, for it can merely be described as a lens, as it decides how someone views the events happening around them. Perception is the definition of how someone decides to use their senses to observe and make conceptions about events or conditions they see or that are around them. Perception also represents how people choose to observe regardless if it’s in a negative or positive way. In other words, perception can be described as people's cognitive function of how they interpret abstract situations or conjunctures around them. All in all, perception can do three things for someone: perception can change the way someone thinks in terms of their emotions and motivations, perception acts
