Visual perception depends on both what our eyes see and how our brain interprets that visual information. Our perception is shaped by our individual experiences and cultural background. Optical illusions demonstrate how perception can differ from objective reality, influenced by expectations, assumptions, and learned associations. Artists have also created impossible figures that play with visual perception beyond real-world constraints. In summary, seeing involves both the eyes and the brain, and perception varies between individuals based on their unique perspectives and interpretations.

Visualperception
1) Visual perception is how we interpret and make sense of what our eyes see based on our prior knowledge and experiences.
2) Perception is influenced by culture, society, and personal experiences as different people can perceive the same thing in different ways.
3) Optical illusions demonstrate how perception can be deceptive as images are not always interpreted as they truly are due to the brain's interpretation of visual information.
Optical illusions
There are three main types of optical illusions: physiological, pathological, and cognitive. Physiological illusions involve brightness, color, location, dimension, and movement perceptions. Pathological illusions relate to sickness and disease. Cognitive illusions are ambiguous, distorting, paradox, or fictional illusions and involve perceptual organization, depth and motion perception, color and brightness constancies, object consistencies, and future perception. Optical illusions can be funny to find and understand.

Nielsen surrealism ppt_margritte
This document discusses two Surrealist artists, Salvador Dali and Rene Magritte. It provides examples of the strange and imaginative subjects and imagery found in their paintings, such as melting clocks and everyday objects in unusual contexts and sizes. It also shares a quote from Magritte about Surrealism meaning "barring from your mind all remembrance of what you have seen and being always on the look out for what has never been." The document goes on to analyze one of Magritte's paintings, Dream House, noting the strange sizes and placements of objects, and asks students to create their own surreal "dream room" collage.
Op art 1
This document discusses optical illusion art, known as Op Art. It explains that optical illusions trick the eye and brain by sending confusing visual messages. Different types of illusions manipulate color, movement, or depth perception. The document provides examples of illusions that use simultaneous contrast of color, grid patterns to cause afterimages, and embedded images to create strange effects. It emphasizes that to create effective Op Art, lines must be exact and compositions must be neat with thoughtful use of color. Interactive apps and pavement artists are introduced that allow creating optical illusion designs.
Negative shape drawings web
The document provides guidance on how to draw using negative space. It explains that negative space is the area between and around the actual object. It encourages the reader to focus on drawing the shapes surrounding the object rather than the object itself. The document then outlines an in-class activity where students will select an object, draw it from three perspectives using negative space, and shade in the drawings. Finally, it suggests techniques like ink, paint, collage, writing, and stenciling that can be used to finalize the negative space drawings.
Nielsen surrealism ppt_miro
The document provides information about Spanish artist Joan Miro. It states that Miro got ideas for his paintings from remembering the plants, animals, and insects on his family's farm, but that rather than painting them exactly as they appeared, he invented colorful imaginary creatures. Miro loved to paint in flowing curvy shapes. Students are then instructed to create their own Miro-inspired paintings using crayons and watercolors to draw and paint imaginary garden creatures.

Drawing day one
Drawing has a long history used for expression, communication, and recording the natural world. It is used in many contexts from children's early drawings to technical drawings, political cartoons, comic strips, and planning future artworks or projects. While some drawings are made through observation, others are conceived through imagination, perspective, and composition rules.
Year 8 canopic jar
This document provides instructions for a project where students will design and create a canopic jar inspired by ancient Egyptian art. Students will learn sculpting techniques like coil building and modeling to form the jar and attach an animal head. They will also learn decorative techniques like incising, engraving, and glazing to decorate the jar with Egyptian-inspired patterns. The goal is for students to understand ancient Egyptian beliefs about death and afterlife through hands-on creation of a canopic jar.
Bridget riley
Bridget Riley was a pioneer in Op Art, which uses precise line, shape, and color arrangements to create the optical illusion of movement in two-dimensional images. Popular in the 1960s, Op Art compositions are designed to trick the eye into perceiving depth and motion that are not actually present. Riley was born in London in 1931 and had her first solo art show in 1962, establishing her as the "Mother of Op-Art" through works that explored optical effects through geometric patterns and grids.
Opartshadingblobs
This document provides instructions for an art project called "Op Art shading blobs" where students will create an optical illusion design. It explains that Op Art uses tricks of the eye to make images seem like they are moving. Key steps include drawing curved lines and connecting dots to fill the page before adding just two complementary colors with darker shades in the corners and lighter toward the tops of shapes. The objectives are for students to understand concepts like line, space, value, color and movement through creating their own Op Art.
Symbols
This document discusses symbols and what they represent. It defines a symbol as a picture or object that makes people think of a country, place, or group of people. It then asks the reader to identify which pictures shown would be considered symbols.
Drawing, printing and sculpture
Drawing techniques taught include sketching, drawing from memory, imaginary drawings, and abstract or conceptual drawings. Printing methods like block printing and paper collage are covered, as well as painting. Sculpture instruction incorporates paper crafts, working with clay, and using other mediums.
2014 Year 5 Art
The document discusses Op Art, which uses optical illusions to trick the eyes. It notes that M.C. Escher and Bridget Riley are famous Op Art artists. The second half provides instructions for creating Op Art shading blobs by drawing a curved line, adding dots, connecting the dots with bumps that extend past the paper edges, and applying varying shades within the bumps.
Optical Illustions with emphasis on Escher
An optical illusion is an image that tricks the viewer's mind by distorting or changing what is seen. Optical illusions do not actually deceive the eye itself, but rather trick the brain by manipulating light and shadows in a way that the brain interprets differently than reality. Famous artist M.C. Escher was renowned for his optical illusion artworks, often utilizing simple geometric shapes like circles that he manipulated in impossible ways to confuse the viewer's perception.

Optical illusion
Optical illusions visually trick the brain by making images appear different than reality. There are three main types of optical illusions - literal illusions that create different images than the objects, physiological illusions caused by excessive stimulation of the eyes/brain, and cognitive illusions from unconscious inferences. Throughout history, different types of optical illusions have become popular based on the time period, including ambiguous images from the early 1900s and abstract op art in the 1960s that appeared to move. Optical illusions work because the mind cannot view exact details or multiple images at once, instead interpreting visual stimuli in a way that creates illusions.
PRECEPTION (ADT)
The document discusses visual perception and how it relates to architecture. It explores several theories of visual perception, including neurophysiology, Gestalt theory, constructivism, and ecological perception. The document also includes many visual examples to illustrate concepts like figure-ground discrimination, grouping, and how perception is influenced by existing knowledge and cultural norms. The overall message is that visual perception is complex and subjective, and we do not necessarily see things objectively, but rather perceive them based on our existing understanding and frame of reference.
Presentation optical illusions.
Optical illusions are experiences where one sees something that does not exist or is different than reality. They can be physiological from eye/brain stimulation or cognitive from unconscious inferences. Some classic illusions are ambiguous figures, distorting perceptions, and future perceptions. Artists use illusions to create effects of space, motion, and perspective. Studying illusions increased understanding of visual processing.
Optical illusions
The document discusses optical illusions and the history of their study. It explains that optical illusions reveal that perception is an active process in the brain rather than a direct reflection of physical reality. The history of illusions is then reviewed from ancient Greece to modern times, showing different viewpoints on the relationship between senses and mind over time. Various types of illusions are also presented including ambiguous figures that can be seen in more than one way.

Chapter6
This document provides an overview of key topics in perception, including selective attention, perceptual illusions, perceptual organization, depth perception, motion perception, perceptual constancy, perceptual interpretation, sensory deprivation and restored vision, perceptual adaptation, perceptual set, and the role of human factors in perception. It discusses experimental findings and defines important concepts such as inattentional blindness, change blindness, grouping principles, monocular and binocular depth cues, shape and size constancy, and schemas. Examples of perceptual illusions and demonstrations of perceptual effects are also described.
ChrisLandauer-illusions.ppt
This document provides a history of optical illusions from prehistory to modern times. It discusses how illusions challenge human reliance on the senses providing an accurate view of reality. Early Greek philosophers debated whether senses were inherently accurate or if the mind played a role in perception. Experimental foundations were later established in the 1800-1870 period. Current study of illusions follows a paradigmatic scientific approach through normal science, anomalies, and revolution. The document concludes by examining ambiguous figures and how single images can represent multiple interpretations.
Introduction to sense perception
This document discusses sense perception and how we make sense of the external world through our senses. It outlines the five main senses of sight, smell, taste, touch, and hearing, while noting scientists disagree on the total number, which may be between 9 and 21. When we lose senses, as in Helen Keller's case of losing sight and hearing, we rely more on our remaining senses. The document contrasts empiricism, which believes knowledge comes from the senses, with rationalism, which believes knowledge comes from reason. It also discusses how illusions reveal the limitations of direct realism and show perception is subject to interpretation within the brain. Cultural and personal contexts influence how we perceive and interpret the world. While senses provide information, perception

Optical illusions
Optical illusions trick the brain by using patterns, colors, and light to create images that do not match reality. The brain interprets visual information from the eyes to form perceptions. Optical illusions occur when the brain's interpretation does not match the actual image. Op art uses optical illusions through geometrical or organic patterns. Students will create their own op art by drawing squares then developing a cube with classmates to display multiple illusions.
Optical Illusions By Saina
This document provides an overview of different types of optical illusions including:
- Facial/Ambiguous Illusions which show two figures that are difficult to see simultaneously
- Distortion Illusions which use patterns to make objects appear differently sized than they are
- Afterimages which cause continued images to appear after viewing something for 20-60 seconds
- Impossible Figures which use 2D images that appear 3D but cannot exist physically
- Color Illusions which trick the brain into perceiving colors incorrectly due to light and dark contrasts
The document explores the history of optical illusions and provides examples to illustrate different types. It also includes a bibliography citing sources used.
Sensation and perception_2012
The document discusses sensation and perception, explaining that sensation is the detection of physical stimuli from the environment which is converted into neural signals, while perception involves selecting, organizing, and interpreting sensations. It covers topics like perceptual interpretation, information processing in the visual cortex, visual perception principles like figure-ground and Gestalt principles, and how perception involves both bottom-up sensory processing and top-down cognitive processes.
Final project post
This document summarizes the key points learned from a perception psychology class. It discusses how perception involves complex processes behind recognizing stimuli in the environment. The author was fascinated by how depth and size are perceived, including visual illusions like the Ponzo and Ames Room illusions. They conducted an experiment using the "thumb technique" to test if objects of different sizes could have the same visual angle. The document concludes by discussing how perception applies to everyday life and how the author will now view the world differently.

1) The document provides a historical overview of perspectives on autism from 1820 to 2020, highlighting several key milestones.
2) In the 1940s, Kanner and Asperger independently identified and named autism as a distinct syndrome, describing features like insistence on sameness and isolated skills.
3) In the 1960s, research shifted away from viewing autism as caused by parenting and toward studying cognitive and information processing deficits, applying new psychological models.
Perception of Reality 1
Our understanding of reality comes from personal experiences and sensory perceptions, as well as authorities, factual evidence, references, and cultural traditions. However, our perceptions are limited and subjective, so our individual realities may differ. Philosophers have explored this concept through thought experiments about prisoners seeing only shadows in a cave (Plato) or an evil demon controlling our perceptions (Descartes). We cannot be certain that what we perceive as reality corresponds to an objective reality that exists independently of our minds.
Eye brain-gregory
This document provides an introduction to the psychology of seeing and perception. It discusses how the eye and brain work together to transform retinal images into perceptions of three-dimensional objects in the world. While the eye functions somewhat like a camera, the brain's role in perception goes far beyond merely processing images. The brain actively organizes sensory data to perceive objects, even when stimuli are ambiguous. It draws on past experiences and knowledge to interpret patterns of light. Understanding these perceptual processes can explain visual illusions and how the same retinal image can result in different perceptions of objects and their positions in space.

Chapter 6 ap psych- Perception
Perception involves selecting, organizing, and interpreting sensory information to recognize meaningful objects and events. However, our perception is not always accurate due to various cognitive illusions and failures of attention. For example, inattentional blindness refers to failing to notice an unexpected object, while change blindness involves failing to notice changes between scenes. Perception results from both innate and learned processes, and is influenced by context, experience, and expectations.

Colour 3r eso
Colour can be perceived through sight when light interacts with objects. Sir Isaac Newton discovered that white light is made up of the visible light spectrum, including red, orange, yellow, green, blue, indigo, and violet colors. Colour theory explores how colors are created and mixed through additive primary colors of red, green and blue or subtractive primary colors of magenta, cyan and yellow. A document on color theory discusses qualities like hue, value, saturation and temperature, and how colors relate and are organized on a color wheel and color cube.
Visual language
This document discusses visual language and how images communicate through different levels of iconicity. It defines iconicity as the similarity between an image and reality. Images can have a high, medium, or low degree of iconicity depending on how closely they resemble reality. Visual language is an important communication system that uses images to transmit information in various contexts like art, publicity, movies and more. The document also describes different visual art styles from realistic to figurative to abstract and encourages transforming a realistic artwork into a personal figurative style.
Elements bàsics del llenguatge visual
The document discusses basic visual elements including dots, lines, and shapes. It focuses on dots and lines, describing the two types of each. Dots can be geometric or graphic, and they are the smallest visual element. Lines are tracks made by moving points, and can also be geometric or graphic. The document explores line characteristics like intensity, thickness, and color, and different line types including horizontal, vertical, oblique, and curved lines. Art styles like Pointillism and works by Seurat, Signac, and Lichtenstein are mentioned in relation to using dots.
Imagesandperception
Images serve various communication functions. They can inform by providing clear descriptions, identities, and indications. Images also sell ideas and products through publicity. Additionally, images provide enjoyment in media like films, magazines, and art for aesthetic purposes. An image may realistically depict reality, use figurative symbols, or take abstract non-representational forms. The document discusses the value, uses, and relationships between images and perception.
Logos
A logo is a group of letters, signs, or graphic marks that identifies a trademark or company. Logos are simple, easy to remember, and aim to transmit an idea or feeling about the trademark through letters with or without pictures, or through only pictures or graphic signs. The key reasons logos are memorable are that they are simple, use only one to three colors, are easy to read, and try to convey meaning about the trademark through images or feelings.
Textures
This document discusses textures in art. It will teach about different types of textures including rough, bumpy, slick, scratchy, smooth, silky and soft textures. Tactile textures are perceived through touch, while visual textures represent tactile textures using graphic elements. Natural textures come from nature while artificial textures are man-made. Artists use textures in their works to imitate reality, express emotions, or create imaginary worlds. Learners will practice creating textures using materials like paint, paper, beans and fabric or techniques like painting, drawing, stenciling, collage and transforming existing artworks.
Colour
This document discusses color as a physical phenomenon and in art. It explains that light is made up of all colors and how primary, secondary, and tertiary colors are formed from the mixing of primary colors. Specific artists like the Impressionists, Fauvists, and Sonia and Robert Delaunay are highlighted for their innovative use of color in their artwork. Activities are suggested for students to experiment with mixing primary colors and creating their own art inspired by these styles.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Visualperception
- 1. VISUAL PERCEPTION THE WAY WE SEE
- 2. LOOKING AND SEEING SEEING IS MORE THAN LOOKING Looking is how our eyes build an image of things. Seeing is looking with attention. All the people see things in a different way. The way everyone sees is called PERCEPTION.
- 3. What’s PERCEPTION? To perceive is to interpret what we see. Our eyes receive information, and our brain interprets that information. This interpretation depends on the things we have learned before about the object we are seeing.
- 4. What’s PERCEPTION? • Perception depends on our culture and our memory. PERCEPTION = SENSE INFORMATION + CULTURE
- 5. PERCEPTION If we don’t know anything about astronomy, we aren’t able to read the stars in the sky. Astronomers know the name of the stars and planets. They see the sky in a different way than people who doesn’t know.
- 6. CULTURE AND PERCEPTION Some people perceive in a different way although they are looking at the same thing. That is because perception depends on culture, society and personal experience.
- 7. CULTURE AND PERCEPTION • For example, before America was discovered, the american indians never had seen a man riding a horse. When they saw spanish soldiers riding horses, indians were scared because they thought that spanish were monsters. Indians didn’t have any experience about men riding horses, so that was very strange for them.
- 8. SENSE AND PERCEPTION • Sometimes, our brain builds an image different from the real one: sight is deceiving us. • Is really there the number 1 in this logo?
- 9. OPTICAL ILLUSIONS Optical Illusions are images perceived in a different way that they really are. Are these vertical lines parallel?
- 10. OPTICAL ILLUSIONS • Which is longer?
- 11. OPTICAL ILLUSIONS • Which of the internal circles is bigger?
- 12. Ambiguous shapes •What do you see?
- 13. Ambiguous shapes • What do you see? •A duck or a rabbit?
- 14. IMPOSSIBLE FIGURES •Always upstairs... Or downstairs!
- 15. IMPOSSIBLE FIGURES • Can you find them in the real world?
- 16. ART AND IMPOSSIBLE FIGURES • Maurits Cornelis Escher (1898-1972) was a Dutch artist. In his drawings, he created a fantastic and magical world full of impossible figures.
