Is it true? Look at an optical illusion and you may think you're seeing things, such as a curved line that's actually straight, or a moving object that's standing still. You wonder if your eyes are playing tricks on you. But you can’t help but thinking, could it be real?
It's not all in your eyes. An illusion is proof that you don't always see what you think you do because of the way your brain and your entire visual system perceive and interpret an image. Visual illusions occur due to properties of the visual areas of the brain as they receive and process information. Your perception of an illusion has more to do with how your brain works and less to do with the optics of your eye.
Everything that enters the senses needs to be interpreted through the brain, and these interpretations occasionally go wrong. Illusions, may serve as a test to determine whether scientists understand vision correctly. When light hits our retina in the eye, about one-tenth of a second goes by before the brain translates that into a visual perception of the world. Our brains compensate for this neural delay and so it attempts to generate an image of what it will perceive one-tenth of a second in the future. Optical illusions occur when what our brains predict does not match the reality.
A better way to think of it is in order to compensate for this massive loss of information and provide us with visual perceptions that are rich in contrast, color, and movement, the brain introduces abstract parameters that often fill in or amplify the fragments of reality that it is given to work with. The brain's powers to interpret visual information in this way are so great that it sometimes creates an impression of coherence where there is none, in other words, an optical illusion. Also it's because we learn to process certain images automatically. This is because our early development "hard wired" our perceptions. As a result, we learn to subconsciously interpret the images we see every day. As a result of that, our minds learn to recognize and automatically process images and associate them with meaning and identity. For instance, young children learn to distinguish unique features in individual faces early in life. The most amazing thing might be is how the brain all while is trying to predict what is about to happen in the very near future.
The brain is one of the most important parts of the body, for good reasons. But even the best get messed up or can be tricked at something. The brain, in all its wonders, can at times even outsmart itself per-say, providing a live stream through the eyes while searching for any and every tiny clue available for what to expect next, therefore making it susceptible to tricking itself every once in great while. But in it all, I can’t help but admire at how amazing God made us humans, and in this case, specifically our brains.

Science and Optical Illusions of Athabasca Falls

...seemingly simple, majestic and powerful display of water is in fact a series of molecular bonds, laws of physics and optical illusions which interact in complex manners, creating the fascinating effect we can observe. Memo Report Optical illusions are caused by many factors, and each one can cause a different effect. In this paper, we will see the causes and effects of the Afterimage effect, and how it can be explained. What is an illusion? An illusion is an impression of a real stimulus which does not agree with any other of the senses, whether physical or psychological. for example, the Athabasca falls illusion causes us to see a rock wall, about 15 metres high, seemingly waving like water. Visually, this is a fact, but if we were to touch the wall during the effect of the afterimage, we would notice that is not moving at all. We have to realise that illusions are not real, and can be caused by many things, overexposure is merely one of these things. By playing with the senses, one can achieve almost any type of illusion, what that is depends on what you do1. The illusion in the eye: A big part of optical illusions are caused by the eyes alone. What we call sight is simply a set of signals interpreted by the eye and transferred via the optic nerve to the brain. This occurs in 7 steps, according to Matthew Luckiesh who wrote a book on optical illusions in 1922. The structure of the eye can be simplified for our purposes by saying it has a roughly......

The Book of Illusions

...The Book of Illusions by Paul Auster If a tree falls in a forest with nobody around, does it make a sound? At one point in his 10th novel, The Book of Illusions, Paul Auster briefly refers to this philosophical concept. If a man, however, lives a life that nobody else notices, did he really live? That's the real debate that he proposes with this novel. The book opens with the sentence, "Everyone thought he was dead." It refers to a silent film comedian named Hector Mann who just disappeared one day back in 1929, but it could just as easily refer to the protagonist of the story, David Zimmer, a literature professor at a liberal arts college in Vermont. David's life came to an end the day his wife and sons were killed in a plane crash. That disaster sent him diving headlong into drink and depression and he lived in an almost catatonic state in front of the television every day. He saw no purpose to living, but he was also unable to take his own life. He divorced society, quit his job, and broke off all contact with the people in his former life. One day, a spark of life emerged while he watched a short clip of a Hector Mann movie on the television. He laughed. That moment of laughter made him realize that there was still something inside him that wanted to live, and he realized he needed a purpose, something to occupy his mind and to get him through every day. David decided to write a book about Hector Mann and his movies. He had previously written several books of......

Illusion

...A case related to illusions Everyday, we hear, we sense, we see a lot of information. When our brain, our perceptual system, misinterprets the information, the perceptual illusions occur. It is a cognitive perception, because you transmit information to the brain and our brain starts to process. I came up with four examples that are either from my own experiences or from my visual observation. And I think they can be used to illustrate perceptual illusions. But I’m not sure whether two of those examples are perceptual illusions. I think they are more similar to optical illusions.  Beauty & Health Care Stores As a girl, I often go to some beauty stores to purchase some cosmetics. Sometimes when I step into a beauty & health care store, I have a feeling that the store is very big and bright. But actually it’s not the case. The owner of the store usually decorate the store with full of mirrors, the mirrors may give the consumers the feelings that this store is really big. It’s often the promotion strategy that the stores used. In this case, the actual and perceived size of the store has a discrepancy. My brain misinterprets the size of the store, and then it’s perceptual illusion.  The railways When I was very young, my parents were too busy to take care of me. So I spent a lot of vacations in my grandparents’ home, and I took the train to their home. Each time when I was on the train and the train was in the platform waiting to leave, I felt that our train was moving......

The Power of Illusion

...Filmmaking - Track B Cultural Mythology and World Religions – Extra Credit Assignment The Power of Illusion 'Kumaré' Kumaré is a documentary about a man who impersonates a wise Indian Guru and starts to build a following. Vikram Gandhi's experiment has been criticized as immoral, many others do agree with his philosophy and “teachings”. The experiment had simply grown out of his control by the time he could reveal his true self. Kumaré's followers in the documentary claimed to be comforted by his energy and presence. There was something about him that drew others to him. People said that he was giving and was willing to spend most of his time trying to help others. But what if it were all for show? When Vikram began his transformation to the all knowing Guru Kumaré he was, in his words “just curious”. This harmless curiosity and openness to the subject may have been exactly what drew his followers to him (That, and he looked the part). He did not set off on a journey to become rich or famous as they suggested was why some other people became Gurus. Vikram went to other established spaces to learn their methods of teaching and incorporated his findings into his own teaching. He also legitimized himself in the eyes of his followers by performing rituals and making up prayers and chants. The identity he adopted was actually the man he wished he could be. Vikram's act became real and he turned into some spiritual placebo that made a great impact on a handful of......

Psych Illusion

...The first illusion was the Muller-Lyer Illusion. It consists of an arrow shape in which the arrowhead faces different directions. In the middle of the shape is another arrowhead that is supposed to divide the length of the arrow in half. The left-facing arrow illusion did little to affect my perception of the distance. However, I was consistently short on the right-facing arrow. The alignment of the arrow drastically affected my perception. I thought I was consistently dividing it in half, but the results showed otherwise. My average adjusted length was about 5.25% less than the correct length. The Muller-Lyer illusion works by altering our depth perception. Because most of us were brought up in square-cornered houses, the >-< shape appears closer and shorter than the shape. This is because the former looks like the edge of an exterior corner and the latter looks like the edge of an interior corner. This causes our mind to perceive the first shape as shorter than the second one, even though they are the same length. After learning about this phenomenon, my score improved from 5.25% to 3.25%. I still haven’t clearly grasped the concept and been able to perceive it correctly, but I did make a slight improvement. The Ponzo Illusion consists of a red and yellow bar whose heights must be matched. The two bars are placed in a room with the red bar much further back than the yellow bar. My perception was significantly affected by this illusion as I made the yellow bar about 49.5%...

Is Life an Illusion

...Is life an Illusion? David Coulter Liberty University Is Life an Illusion? Each of the readings discusses aspects of man being deceived by his senses. In The Matrix, almost every human is plugged into a giant computer and lives out an illusion provided by the computer to the brain (Wachowski, 1999). In The Allegory of the Cave, a hypothetical situation where men are only allowed to see shadows of reality is discussed by Socrates and Glaucon (Plato, n.d.). Finally, in Meditation I of The Things of Which We May Doubt, René Descartes attempts to eliminate all beliefs that might be based on something uncertain. He proposes that a demon may be providing an illusion and his senses may not reflect reality (Descartes, 1641). With all of this investigation around human senses being deceived, is it possible for people to trust their senses? The Matrix and The Allegory of the Cave both deal with how men react to reality when illusion and reality are recognized for what they are. However, they each deal with this recognition in different ways. In The Matrix, reality is far less pleasant than the illusion. Some prefer the truth rather than to be deceived, and one in particular prefers the illusion claiming “ignorance is bliss” (Wachowski, 1999). In The Allegory of the Cave, the hypothetical subjects when confronted with reality find it to be less real than the deceptive shadows that they have always thought was reality. Over time, they learn that the deceptive shadows were and...

Illusions in Relativy

...M. C. Escher, one of the 20th century leading artists, is best-known with his impressive optical illusions. Especially in “Impossible constructions” collection, he did excellent works in playing various visual tricks on those artworks that profoundly confuse the observers at the first sign. The piece of art “ Relativy” depicts an unrealistic interior space with the stairs that never go the same way, the floors, doors and balconies are put on every sides of the rooms in this view. There are also a number of people climbing up and down the stairs and assign “up” or “down” direction in a complicated and strange way, thus completely confuse our visual analysis. However, if the people in motion is supposed to be invisible in the picture, the structure, especially the stairs system seems to be visually possible and at least overall perspective cannot look occur, even though the positions of other furniture pieces may not make logical sense. Therefore, it is effortless for grouping structural elements which are of the same shade and well-connected and well-defined in mass and form. Otherwise, when the number of people moving is involved in the perspective, it can be seen that their shade visually matching with the construction as well as the visual tricks occur to make the picture look ambiguous itself. This is because that three out of four main stairs seem to allow people to climb on both top and bottom, reach and stand on every interior sides of the building, and most......

Optical Illusions

...Optical Illusions Specific Purpose: To inform the audience on how optical illusions work. Introduction Attention Getter: The eye of the beholder. Thesis Statement: The eye gathers information that is processed by the brain and sometimes what we think we see is not what is actually there. No, that doesn’t mean we are all crazy. Relevance: Every day we are surrounded by hundreds of images that are perceived differently from objective reality, though we may not notice it. Preview of Points: Merriam-Webster defines optical illusions as something that looks different from what it is: something that you seem to see but is not really there. Optical illusions can be divided into three types, literal optical, physiological and cognitive illusions. Transition: Let’s explore literal optical illusions. Body I. Literal optical illusions create images that are different from the objects that make them. A. What happens. 1. The illusion exists when the object configured as an image doesn’t exist. 2. From the beginning the image never changes. B. Branches that make up a baby. 1. At first look you may notice a couple looking out at the water. 2. Looking at a broader view you can see the branches are in the shape of a baby. Transition: Physiological illusions are quite different than literal optical illusions. II. Physiological illusions are the effects on the eyes and brain of excessive stimulation of a specific type brightness, color, size, position, tilt, movement. A. The...

Illusions

...Mcman-McCline Vision Light and Color 11/1/14 Cognitive Illusions & Double Exposures Cognitive Illusions can be broken up into various groups of illusions such as, distorting illusions, ambiguous illusions, paradox illusions. I will create an ambiguous illusion using photography as my medium. The illusion will consist of a triple exposure creating three images working together as one. Each exposure setting requires an f-stop in other words the aperture. The aperture controls how much light is let into the lens before the photo is taken. Using multiple exposures f8, f5.6, and f3.5 creating variations of light. My tools consisted of an Argus C3 50mm film camera, black & white film and one light source. The exposures work together creating a beautiful perspective that works along with darks and lights. This causes the viewer to try and figure out which image was taken first and which was last. This ambiguous illusion forms a multistable perception. A multistable perception is the occurrence of an image being able to provide multiple, although stable, perceptions (Susana Martinez-Conde and Stephen L. Macknik). Visual illusions are defined by the dissociation between the physical reality and the subjective perception of an object or event. The picture is interpreted as representing a three-dimensional structure,......

Constancies and Illusions

...Constancies and Illusions What are Perceptual Constancies? * Tendency for the perception of an object to stay constant despite changes in stimuli * Perceptual constancies rescue us from confusion * They allow us to identify objects with different stimuli Three types of constancies: * Size * Shape * Brightness Size Constancy * The most studied of all constancies is size constancy, the fact that an object’s size remains relatively constant no matter what its distance. As an object moves farther away from us, we generally do not see it as decreasing in size. Hold a quarter a foot in front of you and then move it out to arm’s length. Does it appear to get smaller? Not noticeably so. Yet the retinal image of the quarter when it is 24 inches away is half the size of the retinal image of the quarter when it is 12 inches away. We certainly do not perceive the quarter as becoming half its size as we move it an arm’s length. Like other constancies, however, size constancy is not perfect; very distant objects appear to be smaller than the same objects close up, as anyone knows who has looked down from a tall building or from an airplane in flight. Shape Constancy * Tendency for the perceived shape of an object to remain constant despite changes in its retinal image. Ex. A book will have the same shape regardless of the angle it is viewed from. Brightness Constancy * Tendency for the perceived brightness of an object to stay the same as......

Race Illusion

...In the video “Race Illusion” we learn about how throughout history people tend to differentiate between races. We are introduced with the obvious fact that individual human beings are different. Our eyes, skin color, body shape and hair form all confirm this. Daily we use our visual differences into 4 or 5 groups. Not only that, many have this belief that athletic ability, musical aptitude and intelligence plays a part biologically that race is a real thing. In this video we are introduced to a group of students who take part in a DNA workshop. In this DNA workshop, students are to compare their skin colors, type their blood and swab inside their mouth for cell extract for a small portion of their DNA. These group of students include all the races in the world or ethnicity. We have the blacks, the asians, the whites and although not a race, a hispanic too. Those who are of the same race believe that the results will reveal similar backgrounds. So if you’re white, you and the other white student will have very similar DNA. Quite a few of these kids that took part in this DNA workshop were left surprised. For example one kid traced his roots back to Ukraine but to his surprise his results showed ethnic backgrounds from the Balkan peoples and Africa. The world as we know it is much more complicated than we think and race is more than an idea that we prescribe to biology. We see color and we think if a person is a certain race they’ll automatically have different advantages than......

Illusions

...Abstract: In this essay, Ibsen’s plays, The Wild Duck, and Ghosts are considered in relation to themes of illusions and realities. In both plays, families are held together by illusions, yet torn apart by truths that have been concealed to protect the children. Ibsen’s use of artistic realism is an ironic art form where illusions and realisms are contradicted to reveal the deeper conflicts of ordinary lives. Ibsen presents the complicated realities of ordinary lives and emphasizes the fact that there are always many realities -- just as there are many illusions. Title: Illusions and Realities in Ibsen’s Plays The Wild Duck and Ghosts Introduction In Ibsen’s The Wild Duck, illusions and reality are set into a conflict within the story of a son’s personal desire to confront idealism. Throughout much of the play, the son, Greger, argues the value of truth with the reluctant Dr. Relling. Relling insists on the importance of illusions, but fails to discourage Greger’s intentions and a play that begins as a comedy quickly turns into a tragedy because of these conflicts. At the heart of the illusions in this play are the ways that people assume many roles in a family, impersonating multiple ideals as ways for managing their relationships. This theme of impersonation is also developed in Ibsen’s Ghosts, where family relations are slowly undone as the illusions and deceptions are stripped away. In both plays, deceptions are strategic and designed to protect the......

The Illusion of Time

...The Illusion of Time We spend countless moments of our lives worried about time. Trying to be on time, do we have enough time, is it time for something; these are all thoughts that I have and I am sure everyone else has almost each and every day. As a college student I am always saying I do not have enough time to accomplish what I have to do, but as Mr. Greene said, well I guess that simply is not true because time as we know it is simply an illusion. Mr. Greene expressed that time is nothing more than what we allow it to be. Time is something we simply measure based on the sun movement. The clock that we keep is simply the result of a atom bouncing and ticking around. So why do we allow something we made up have such control over us. It’s simple, it helps us stay on track. He remarked that time as we know it can speed up or slow down. But why is that. Well that has to do with a force we have seen a lot this semester; that’s right gravity. Gravity has the ability to pull on time and slow it down. When the pull is stronger time is slower, not exactly what you mean when you saying the time is slow or even flying by, is it? Another interesting topic he discussed was that what we call the future could already exist and what we call the past may not yet be gone. This has to do with the notion that time moves in one direction, but just as we have learned in class that cannot always be. If we change the velocity the direction of time can change.

Example of Financial Illusion in 2000s

...Example of Financial Illusion Introduction The emergence of an increasing number of ‘financial illusions’ in the current state of financial markets around the world casts doubts over the famous and widely accepted efficient market hypothesis. The efficient market hypothesis (EMH) indicates that, at any time, prices fully and instantaneously reflect all available relevant information on a particular stock or market (Fama, 1970). EMH also suggests that it is impossible to “beat the market” because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information. Thus, according to the EMH, it is impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices because stocks are always traded at their fair value on stock exchanges. Another reason is because no one has access to information that is not already available to everyone else. One important characteristic of the EMH is its assumption that agents are rational. Rational agents is agents which has a clear preferences, models uncertainty via expected values, and always chooses to perform the action that results in the optimal outcome from all the feasible actions. Their actions depend on their preferences, their information of the current situation; which may come from past experiences, the actions, duties and obligations available and the estimated or actual benefits that the agents can get after the actions. In reality, however, agents......
