Visualperception
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.
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.
Theories and effects of mass communication (20082423 somi, kim)
Mass communication involves an organization using technology to communicate with a large audience. There are four major categories of mass communication theory: postpositivism, hermeneutic theory, critical theory, and normative theory. Mass communication effects examines how media content impacts individuals and society, as well as how living in a media-saturated world changes interactions and culture. Understanding media effects requires examining messages, mediums, owners, and audiences.
Theories of Mass Media
The document outlines four theories of mass media: the authoritarian theory, libertarian theory, Soviet theory, and social responsibility theory. The authoritarian theory proposes direct government control over media to avoid undermining authority. The libertarian theory advocates for individual freedom of the press. The Soviet theory describes media owned by the state to serve workers under communist ideology. The social responsibility theory sees media as having obligations of informativeness, truth, accuracy, and balance in democracies.
M6 com320 mass_commtheories
This document outlines several mass communication theories: the Magic Bullet Theory which suggests media has a direct influence on audiences; the Two-Step Theory where opinion leaders influence the public; the Agenda-Setting Theory where media tells the public what issues are important; Diffusion Theory where opinion leaders spread messages to influence the masses; and Framing Theory where how an issue is presented influences choices. It provides diagrams and brief explanations of each theory and links to additional mass communication theory resources.
Design & Neuroscience - The Eyes
How eyes receptors work, the influence of the light, eyes movements and how human see things. Presentation taken from first chapter of the book "To see, to think, to design. Neuroscience for design" by Riccardo Falcinelli (http://amzn.to/1UgEOkB).
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.
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.

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.
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.
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.

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.

1) Reality is a personal interpretation of one's surroundings based on their perceptions and cognition, so everyone experiences a different reality.
2) We create our own realities through selective perception, attaching meaning to our sensory experiences based on our culture, experiences, and needs.
3) Optical illusions demonstrate how our perceptions can distort reality by tricking the mind into seeing something that isn't really there.
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.

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.

It describes four main types of illusions: 1) optical or visual illusions, 2) physiological illusions, 3) distorted illusions, and 4) motion illusions. Several examples of illusions are presented, including visual illusions that trick perceptions of color, size, angles, and motion. The document explains that illusions occur because of differences between sensations received by the senses and perceptions interpreted by the brain.
Rl gregory excerpt
This chapter discusses the history of theories about the nature of light. It describes how Christiaan Huygens and Isaac Newton debated whether light was a wave or particle. Experiments by Olaus Roemer in the late 1600s showed that light travels at a finite speed, settling the debate that light does not arrive instantaneously. The chapter also explains how refraction causes light to bend when passing from one medium to another, as described by Snell's law. Modern physics shows that light has properties of both particles and waves.
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.
perception-200619100047.pdf
Perception involves interpreting sensory information from our environment. It is a two-step process of sensation, where stimuli are received by our senses, and interpretation by the brain. Perception is influenced by past experiences, attention, motives, and emotions. Gestalt principles like figure-ground relationships, proximity, and closure help organize discrete stimuli into meaningful wholes. Perception can involve errors like illusions, where external stimuli are misinterpreted, and hallucinations, where perception occurs without external stimuli, as seen in some mental illnesses.
Perception- Psychology
Perception involves interpreting sensory information from our environment. Sensations from our senses are transmitted to the brain for interpretation based on past experiences. Gestalt psychologists identified principles that help organize discrete stimuli into meaningful wholes, such as figure-ground relationships, proximity, similarity, and closure. Factors like sense organs, mental sets, motives, and emotions can influence perception. Illusions involve misperceptions of real external stimuli, while hallucinations are false perceptions without an actual stimulus.
Perception
Perception involves interpreting sensory information to identify objects. Visual perception involves light entering the eye and being transmitted to the brain as electrical signals. The brain must work to make sense of the two-dimensional, upside-down image. Visual illusions occur when the brain misinterprets images due to past experiences. Illusions can be ambiguous, distortions, fictional perceptions, or paradoxes. Depth is perceived through binocular cues like disparity and convergence as well as monocular cues like size, texture, and motion. Visual constancies allow objects to appear the same size, shape, and color despite changes in the retinal image.
Sense Perception
Our perception is influenced by expectations, language, and interpretation. We adjust how we perceive things and use context to resolve ambiguity. However, perception is limited by our biology and neurobiology. For example, we cannot perceive things that happen very fast or slow, or we may have conditions like visual agnosia that limit recognition.
IVC - Lesson 09
Semiotics is the study of signs. Signs can take many forms including words, images, sounds, objects, and behaviors, but only take on meaning when interpreted as representing something else. Perceptual theories of visual communication like semiotics and cognitive approaches emphasize that humans assign complex meanings to visual objects through systems of conventions and mental processes like memory, expectation, and culture that are shaped by experiences. Visual perception is an active process where the brain interprets and makes sense of visual information based on what is known from the past.
The process of perception & art
1) Art can be used to grab attention or relax viewers, but most are unaware of how perception works.
2) There is an order to how we perceive situations and art, including selection, sorting, and interpretation.
3) Our perception is filtered through psychological conditions, physical conditions, language, education, experiences, and expectations, all of which affect how we view and understand art.
New illusions
The document discusses optical illusions and assigns students to create an optical illusion drawing. It begins by defining an illusion as something that deceives the human visual system. It then provides several examples of visual illusions, including images that appear to bend or change depending on one's perspective. Students are asked to understand different types of illusions, draw an illusion using materials like pencil and ink, and present their illusion art to others.
L3 empiricism
The document summarizes key aspects of empiricism according to philosophers like Aristotle, Aquinas, and Locke. It discusses how empiricists believe that all knowledge is derived from sense experience. Aristotle believed we develop universal ideas from our experiences with particular objects through induction. For Aquinas, the intellect can abstract the essence of things from our senses. Locke viewed the mind as initially blank, with ideas developing from sensation and reflection. He distinguished between simple and complex ideas.

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.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
