Introduction to Perception
Introduction

Visual illusions are a major tool in studying neural circuits, brain functions, construction of visual perception etc. The article that follows, discusses the correlation between visual illusions and characteristics of perception by brain that lead to them. The article is an overview of one of the most interesting fields of psychology.

For thorough discussion of the subject, it is necessary to understand and clarify the essential definitions and terminologies involved. The most vital term in this context is ILLUSION.

What are illusions?

“Visual illusions are subjective percepts that do not match the physical reality of the world.”
- Encyclopedia of Perception, edited by E. Bruce Goldstein, Sage Press

“An illusion is a distortion of the senses, revealing how the brain normally organizes and interprets sensory stimulation.”
- Wikipedia, the free encyclopedia Types of Illusions- 1) Visual Illusions 2) Optical Illusions

“The terms visual illusion and optical illusion are often used interchangeably. Visual illusions demonstrate the ways in which the brain fails to recreate the physical world. However, unlike visual illusions, optical illusions do not result from brain processes. Instead, an optical illusion is the perception of a distortion that results from the physical properties of light, such as reflection and refraction, and/or the optics of the eye. “
- Visual Illusions, Pg. 1077

What is perception?

“Perception (from the Latin perceptio, percipio) is the organization, identification, and interpretation of sensory information in order to fabricate a mental representation through the process of transduction, which sensors in the body transform signals from the environment into encoded neural signals.”
- Wikipedia, the free encyclopedia

As Wikipedia describes it, one of the most significant characteristics of Perception is- “Perception is not the passive receipt of these signals, but can be shaped by

    To understand better how the brain processes visual information, an understanding of, and a clear differentiation between sensation and perception is required. Before stimuli can be perceived or interpreted, it must first be sensed through the sense. Therefore, sensation is the stimulation of sense organs (i.e., eyes, ears, nose, mouth, and skin) and involves the absorption of energy, such as light and sound waves through the sensory organs, (Weiten, 1998). Perception refers to psychological processes in which the immediate organization and interpretation of sensations are involved (Riegler & Riegler, 2008) and “involves organizing and translating sensory input into something meaningful,” (Weiten, 1998, p. 123).…

    One may ask the question "What roles do illusion and reality play in the perception of ourselves and others?". Illusion and reality both play a role in the definition of our perception. Illusion is the stereotype, the racist idea, while reality is the truth that one sees when he/she looks closely and tries to understand. This may be seen in To Kill a Mockingbird, by Harper Lee. Once, during Jem, Dill, and Scout's investigation of Boo Radley, or Mr. Arthur Radley, another time, during the whole jury's verdict against clearly innocent Tom Robinson, and yet again, in the illusion that Dolphus Raymond is always drunk and that is why he is in the situation that he is in.…

    Tim Crane Perception

    Tim Crane claims that the usual, instinctual way of regarding perception is as an “openness to the world.” However, the fact that illusions and hallucinations can occur seems to indicate some sort of fault with the typical view, as these bizarre experiences give rise to questions about the nature and coherence of perception. He asserts that in order to escape this problem, philosophers must provide a theory of perception which both maintains integrity to our intuitions and explains how perceptual mistakes are possible. (Crane 1.1) Peter Strawson in his paper “Perception and Its Objects” describes common-sense realism, which he takes to be an explication of our ordinary view of perception, and attempts to resolve the apparent conflict between…

    The goal of this paper is to focus on how gender affects what people see in optical illusions. The differences of male and female brains affect how boys and girls act and perceive the world. If there’s a difference in the vision of boys and girls then there will probably be a difference in how they see an optical illusion. Studies show that there are multiple differences in the male and female brain. There are different types of optical illusions, but this paper is mainly about ambiguous illusions because that is what will be used in the experiment. Ambiguous illusions are pictures with multiple images in them. Evidence from the brain proves that our eyes never actually play tricks on us. It’s our brains and how they perceive the information our eyes send to it. To answer the question, do boys and girls see optical illusions differently, the brain’s relationship with the eyes, the differences between the male and female brain, the differences in the male and female visual system, and how optical illusions work must be factors to understand the subject completely.…

    An optical illusion (also called a visual illusion) is characterized by visually perceived images or views that can differ a ton from objective reality. Optical illusions have been around for centuries, teaching us that you shouldn’t fully trust your senses due to that we can easily be tricked. However, optical illusions can help us learn how easy it is to trick our brain to see an object that seems real but is really not. An example of a well-known visual illusion would be the “Ames Room”. An Ames room is a distorted room that is used to create an optical illusion that uses depth and perspective to make it seem like the room is the same when it actually has been manipulated. This illusion is one of the top and most famous optical illusions…

    Identifying the mechanisms responsible for visual illusions, facilitates comparisons of perceptual accuracy and inaccuracy, and thus helps to inform an understanding of the way in which environmental stimuli come to be represented in the human psyche (Woloszyn, 2010). In the pursuit of such knowledge, controversy continues to reign regarding the Muller- Lyer Illusion. Despite the equal length of the left and right line in Figure 1, confluxion describes the overestimation of the right line due to the…

    The Divided Line

    • 3 Pages

    The world of the visible is made up of opinion. The people in this world have some knowledge but they also lack a lot of it too. Also they are divided between those who believe and those who follow appearances. Those who follow appearances have the lowest form of knowledge. They can not make a distinction between an illusion and the real thing. For example if they are looking at say a rock and a picture of that same rock. They are unable to distinguish which one is real. They do not know that the rock itself is real and that the picture is an illusion. And if they are asked to choose which one is real, they would most likely choose the picture of the rock over the real one. In other words they would choose the illusion over the real thing.…

    Is seeing believing? Is the universe a lie? These questions challenge the accuracy of our perception of reality-is reality truly what we believe it to be? Our perception of reality is not always necessarily true. People often misunderstand situations and twist the truth for their convenience. Furthermore, our eyes and our brain are also easily confused and misdirected. There are many circumstances where what we believe isn’t true and our impression of the truth is far from actuality.…

    An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a perception that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, colour, size, position, tilt, movement), and cognitive illusions, the result of unconscious inferences.…
