Arguments Against The Grand Illusion

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.

C. Illusions, are simple perceptions, which although produced by an external stimulus are misinterpreted by the client. The information gathered by the eye is processed in the brain to give a perception that does not tally with the physical measurement of the stimulus source.

Our past experiences, also influence the way we perceive new visual stimuli and make sense of it. However, without each process the world would be unknown to us. Without sensation, we would not be aware of the blind spot, and without perception there would be no rational making sense of the surround to complete the image or have any understanding of it. The filling-in illusion is part of our everyday life, we don’t realize it because the two processes are currently and have been working together for quite some time; although, at what point in our lives it begins we are unsure. Regardless, seeing our surroundings as one complete picture is a rather important part of vision and how our brains contribute is an amazing

According to research, the earliest experimental change blindness is developed from the phenomena such as eye movements and more on working memory. It depends on the personal attention to the images they perceive (MacWhinney, 2001). Although individual have well informed and good memory on whether or not they have perceived an image, they also have poor recalling ability especially on the smaller details that are presented in that image. This is evidently through presentation of the complex pictures that are stimulated

Illusion motif. Nothing is what it seems. Only until he realizes that it affects his own reality did he tries to

“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.

It has been a common assumption that “seeing” comes from the ability of one’s eye to

One failure of awareness that seems to have a connection with traffic accidents is change blindness. Rensink (2002) proposed that change blindness occurs when a change within the scene goes unnoticed, due to the inability or difficulty to detect it. Resink (2002) also explained that change blindness can take place during a disruption in vision, such as an eye- movement or a blink.

As the species that depends on sight more than any other scent, seeing so often has certainly become much more than believing, which is only further reinforced by this age of intense and numerous visual stimuli. Upon my recent visit to New York City, I could easily see that the line for the virtual city ride at the Empire State building was much longer than that for the observation deck. This mania for visual experience has taken over, increasing our conviction in what we see as what is, despite their crucial differences. Yet, this is no newfound novelty. The human tendency to take things at their face value is ancient and persisting. This excessive dependence on visual stimulation has led to an excessive false belief in the falsity of appearances; a belief that causes the casual classification of people that is so rigid and narrow in its function that failure to fit into them results in losing one's sense of identity, even when identity is itself such a fluid and complex concept. I have always contended that human beings have a tendency to classify what we experience into categories and assign them with labels. With our dependence on visual stimulation, we generate concepts and categorizations based on what we see, and file them away to be used on a wider scale, allowing those who live in China and those who live in the UK to synthesis the signified through a similar signifier. As our world becomes more

In the story Magic in the brain it explains illusions and how illusions fool your mind. For example on page 79 lines 68-69 it states that” They manipulate the focus and intensity of human intension, controlling, at any given instant, what we

So just what is it that makes people unable to make simple observations about the things around us? Even when they are right in front of us, we still struggle to acknowledge that they are there. How many times have you heard recounts of a car accident where the person at fault says, “I did not see them coming”. How many times can you recall leaving your phone somewhere and not being able to see it when its staring you in the face? How many times have you kicked yourself for something like this occurring when at the time it seemed like they were no where to be seen? It is simple, psychological research tells us that despite continuing image shifts, attention to specific features in a visual scene can be critical in ensuring stable perception. (Cavanaugh & Wurtz, 2004). We can overcome this phenomenon however, if the right amount of spatial attention is allocated to the changing features. The flicker paradigm has become a useful psychological tool in change detection. It allows us to rule out influences from other known causes to change blindness such as eye movements, visual saccades, or a change in location. It has been designed so that any changes detected can be directly associated with attention. By manipulating perceived images in participants, we are able to study the role of attention in relation to change blindness. Research has concluded that without due visual attention, observers are blind to change. (Rensink et al. 1997). Therefore we

Because we are so involved with something, our brains can’t take in other information and deems other surroundings as unnecessary. Because people were so focused on where the basketball was travelling, no one was able to pick up on the gorilla coming into scene. The gorilla was seen as something unnecessary to viewers. Chabris and Simons are exclaiming that individuals are commonly deceived by what they see. It is not necessarily a question of an illusion, but rather one of how your brain perceives information.

Change Detection: To See or Not to See: The need for Attention to Perceive Changes in Scenes

The only thing in my life that I can be positive about is change. Everything changes, from the moment we’re born to the moment we die. Reality has many twist and turns, and our perception of reality is what shapes us to become who we are. Our life is spent on deciphering the difference between reality and not reality. This is hard to define because reality is unique to each individual.

In Sigmund Freud’s famous philosophical work titled The Future of an Illusion, he uses psychoanalysis to explain the origins of the concept of God. He presents valid arguments as to why God is merely a concept created by humans to answer frustrating questions about life in a satisfying way, and the work seems to be sound in its entirety. However, there is an important weakness in Freud’s reasoning in that if God is meant to create order in the universe, why does the thought of Him create conflict, fear, and contradiction? Furthermore, though his psychoanalytic explanation provides fascinating answers to why people believe in God, it cannot demonstrate that God definitely does not exist.
