The color assimilation grid illusion, also known as the Chubb illusion, is a perceptual phenomenon where black and white grid lines appear to take on the color of the surrounding grid squares when a few colored lines are added to the image.
The illusion is created by overlaying a grid of black and white lines on a background of colored squares. The colored squares are typically of different colors, and a few colored lines are added to the grid. When the image is viewed, the black and white lines appear to take on the color of the surrounding squares, creating the illusion that the entire image is in color.
The exact mechanisms underlying the color assimilation grid illusion are still not fully understood. However, it is thought to be caused by the way in which neighboring colors and lines interact with each other, and how the brain processes and interprets visual information. The illusion is a fascinating example of how our perception of color can be influenced by surrounding visual stimuli.
How does the Color Assimilation Grid Illusion Work?
The Color Assimilation Grid Illusion, also known as the Chubb illusion, works due to the way our brains process visual information. Our brains have the ability to fill in missing information based on the context of the surrounding visual stimuli.
In the case of the Color Assimilation Grid Illusion, the black and white lines of the grid are surrounded by colored squares. When a few colored lines are added to the image, our brains try to make sense of the new information by processing it in relation to the context of the surrounding colors. As a result, the black and white lines take on the hue of the surrounding colored squares, giving the illusion that the entire image is in color.
This phenomenon is also known as color assimilation, where the colors of adjacent areas can influence the perceived color of an object or area. The exact mechanisms underlying the illusion are not fully understood, but it is believed that they involve complex interactions between the visual system’s processing of color and brightness, the integration of visual information across spatial locations, and the influence of contextual information on visual perception.
Overall, the Color Assimilation Grid Illusion is a fascinating example of how our perception of color can be influenced by surrounding visual stimuli, and how our brains work to fill in missing information based on the context of the visual environment.
Some Similar Illusions
There are several illusions that are similar to the Color Assimilation Grid Illusion in that they involve the influence of surrounding visual stimuli on our perception of color and brightness. Here are a few examples:
Mach bands illusion: This illusion involves the exaggeration of contrast at the edges of a gray scale. When two adjacent gray bars of slightly different brightness are placed next to each other, the edges between them appear to be darker and lighter than they actually are, creating a banding effect.
Simultaneous contrast illusion: This illusion occurs when a color is perceived differently depending on the colors that surround it. For example, if a gray patch is surrounded by a black background, it will appear lighter than if it is surrounded by a white background.
White’s illusion: This illusion involves the perception of brightness and size of circles. When a small circle is surrounded by a larger circle of the same brightness, the smaller circle appears darker and smaller than it actually is.
Hering illusion: This illusion involves the perception of the curvature of lines. When two parallel lines are surrounded by converging or diverging lines, they appear to be curved.
Adelson’s checkerboard illusion: This illusion involves two squares of different shades of gray placed next to each other on a checkerboard pattern. Although the two squares are of different shades, they appear to be the same shade due to the influence of the surrounding squares.
These are just a few examples of the many illusions that exist and demonstrate the fascinating ways in which our perception of color and brightness can be influenced by the surrounding visual environment.
Discovery of the Color Assimilation Grid Illusion
The Color Assimilation Grid Illusion, also known as the Chubb illusion, was first described by two researchers named George Mather and David H. Kelly in a scientific paper published in 1997. They named the illusion after one of their graduate students, Michael Chubb, who had discovered it during a class demonstration.
Mather and Kelly’s paper, titled “The Measurement of Visual Motion,” reported the results of several experiments they conducted to study the perception of motion in visual stimuli. As part of these experiments, they observed the Color Assimilation Grid Illusion and recognized it as a novel and interesting visual phenomenon.
Since the initial discovery of the Color Assimilation Grid Illusion, it has become a popular topic of study for researchers in the field of visual perception, and it continues to be used as a tool for investigating the mechanisms of color perception in the human brain.
The Storseisundet bridge is a famous bridge located on the west coast of Norway, in the municipality of Ålesund. It is part of the Atlantic Ocean Road, which is a scenic route that runs along the rugged coastline and through several small islands, and is considered one of the most beautiful drives in the world.
The Storseisundet bridge is known for its dramatic curves and arches, which make it appear as if it is rising up out of the water. It is also famous for its optical illusion, where from a certain angle it appears as if the bridge is not connected to the mainland, but rather ends abruptly in the middle of the water.
The bridge is a popular tourist attraction and has been featured in several movies, TV shows, and commercials.
How does the Storseisundet Bridge Illusion Work?
The illusion of the Storseisundet bridge appearing to rise out of the water and not being connected to the mainland from certain angles is an example of a forced perspective illusion. Forced perspective is a technique that uses optical illusions to make objects appear larger, smaller, closer or farther away than they actually are.
In the case of the Storseisundet bridge, the illusion is created by the bridge’s design, which includes several curves and arches. When viewed from a certain angle, typically from the side of the road, the arches of the bridge appear to be much taller than they actually are, which creates the illusion that the bridge is rising up out of the water.
At the same time, the road leading up to the bridge is designed to be narrow and steep, which makes it appear as if the road is rising up to meet the bridge. This adds to the illusion that the bridge is not connected to the mainland, but rather ends abruptly in the middle of the water.
Overall, the illusion of the Storseisundet bridge is created by a combination of the bridge’s design, the road leading up to it, and the viewer’s perspective. It is a great example of how optical illusions can be used to create stunning visual effects in architecture and design.
Some Similar Illusions
The Storseisundet Bridge Illusion uses forced perspective which is a technique that can be used to create a wide range of illusions, and there are several examples of similar illusions that use similar principles. Here are a few examples:
Ames room illusion: This illusion is created by building a room that is shaped like a trapezoid, with one corner much closer to the viewer than the other corner. When viewed from a certain angle, the room appears to be a perfectly rectangular shape, but in reality, the walls are slanted and the ceiling is higher on one side. This illusion is often used in movies and TV shows to make actors appear larger or smaller than they actually are.
Forced scale illusion: This illusion is created by placing objects of different sizes in a way that makes them appear to be the same size. For example, a person standing farther away from a larger object will appear to be the same size as a person standing closer to a smaller object. This illusion is often used in photography and art to create interesting visual effects.
Tilted room illusion: This illusion is created by building a room that is tilted at an angle, so that the floor and walls are not parallel to each other. When viewed from a certain angle, the room appears to be a perfectly normal rectangular shape, but in reality, the floor and walls are slanted. This illusion can be used to create interesting visual effects, such as rooms that appear to be sliding or tilting.
Oversized object illusion: This illusion is created by placing an object that is much larger than it should be in a scene. For example, a giant spoon or pencil can be placed next to a person or a building to make them appear much smaller than they actually are. This illusion is often used in advertising and marketing to create attention-grabbing visuals.
Discovery of the Forced Perspective
The Storseisundet Bridge Illusion used forced perspective has been used in art and architecture for centuries, and its origins are not clear. However, it is known that the technique was widely used by Renaissance artists such as Leonardo da Vinci and Andrea Mantegna to create the illusion of depth and three-dimensionality in their paintings.
The term “forced perspective” was first used in the 20th century by Richard Fleischer, a film director, who used the technique in his movies. Fleischer popularized the term and the technique, which involves using optical illusions to create a sense of depth and dimensionality in a scene.
Today, forced perspective is used in a wide range of fields, including film and television, photography, art, and architecture. It continues to be a popular technique for creating stunning visual effects and illusions.
What is the Color Constancy – Are the Strawberries Red?
Color constancy is the phenomenon where the perceived color of an object remains relatively constant under different lighting conditions.
The color constancy illusion can cause us to misjudge or perceive colors differently based on their context or surroundings. Our brain often adjusts our perception of an object’s color to account for changes in lighting or context, allowing us to see colors relatively consistently across different environments.
How does the Color Constancy – Are the Strawberries Red?
Color constancy works through a process known as chromatic adaptation. Chromatic adaptation is the ability of the human visual system to adjust its response to different lighting conditions, in order to maintain a relatively constant perception of the color of objects.
When we look at an object, the light reflecting off it enters our eyes and stimulates the cone cells in our retina that are responsible for detecting color. These cone cells are sensitive to different wavelengths of light, and they send signals to our brain that are interpreted as color.
However, the color of the light that illuminates the object can vary widely, and this can affect the color signals that are sent to our brain. In order to compensate for changes in the lighting conditions, our visual system adjusts the sensitivity of our cone cells to different wavelengths of light. This process is called chromatic adaptation.
When our visual system encounters a scene with different lighting conditions, it first identifies the overall color of the light in the scene. It then adjusts the sensitivity of the cone cells to match the spectral properties of the light, in order to maintain a consistent perception of color. This adjustment process occurs automatically and unconsciously, allowing us to see colors accurately despite changes in lighting conditions.
However, in some situations, such as when an object is surrounded by colors of a different hue or brightness, the color signals sent to our brain can be influenced by the context in which the object is viewed. This can lead to color constancy illusions, where our perception of an object’s color is affected by the surrounding colors or context.
Some Similar Illusions
There are several illusions that are similar to the color constancy illusion in terms of how they can affect our perception of color:
Simultaneous contrast illusion: This illusion occurs when the perception of a color is influenced by the colors surrounding it. For example, if you place a gray square next to a white square and a black square, the gray square will appear to take on the complementary color of the adjacent squares. This illusion is caused by the way our visual system processes information about color and brightness.
Color assimilation illusion: This illusion occurs when an object appears to take on the color of the surrounding area. For example, if you place a green square next to a blue square, the green square may appear to take on a bluish tint. This illusion is caused by the way our visual system processes information about the interaction between colors.
Chromatic adaptation illusion: This illusion occurs when our perception of color is affected by our previous exposure to different colors or lighting conditions. For example, if you spend time in a room with yellow lighting, your perception of white objects may be affected, making them appear yellowish even when viewed in a different environment. This illusion is caused by the way our visual system adapts to changes in lighting conditions.
All of these illusions are related to the way our visual system processes information about color and the environment, and they can all affect our perception of color in different ways.
Discovery of the Color Constancy – Are the Strawberries Red
The phenomenon of color constancy has been observed and studied by many scientists throughout history, but it was first described in detail by Johann Wolfgang von Goethe, a German writer, poet, and philosopher in his 1810 book “Theory of Colours.” Goethe observed that the perceived color of an object was affected by the color of the surrounding area, and that the human visual system was able to adjust its perception of color to compensate for changes in lighting conditions.
Later, in the 19th and 20th centuries, researchers such as Hermann von Helmholtz, James Clerk Maxwell, and Edwin H. Land, among others, conducted experiments and developed theories to explain the mechanisms behind color constancy. Today, color constancy remains an active area of research in vision science, psychology, and neuroscience.

This Spinning Spiral Illusion uses the phenomenon peripheral drift to create the illusion of motion.
When you view the image directly, there doesn’t appear to be much movement. However, when you are looking close, but not directly at the image (from your periphery) the image will seem to spin.
So, when you are reading this text, the object will appear to spin, but you can stop the motion by looking directly at the image.
If you are interested in the learning more about the Spinning Spiral Illusion peripheral drift, scroll down to learn more about it.
The Spinning Spiral Illusion is a type of peripheral drift illusion which creates the impression of motion in a stationary image. The illusion was discovered by American psychologist and artist Roger Shepard in 1990.
The peripheral drift illusion typically involves a pattern of concentric circles or spirals that are arranged in a way that creates the impression of motion in the periphery of the visual field. The illusion occurs because the patterns create conflicting cues about the direction of motion, which can cause the visual system to perceive motion where none exists.
One common example of the peripheral drift illusion is the Pinna-Brelstaff illusion, which was discovered by Italian neuroscientist and artist Massimo Pinna and British artist Patrick Brelstaff in 2000. In this illusion, a series of black and white wedges are arranged in a spiral pattern. When the image is fixated, the wedges appear to be moving in a circular motion, despite the fact that they are actually stationary.
The peripheral drift illusion is thought to occur because the pattern of the concentric circles or spirals creates a gradient of motion signals that conflicts with other motion signals in the visual field. This conflict can create the impression of motion in the periphery, even when the image is actually stationary.
The peripheral drift illusion is a fascinating example of how the brain processes visual information and can create the illusion of motion where none exists.
How does the Spinning Spiral Illusion Work?
The Spinning Spiral Illusion is a peripheral drift illusion which works by exploiting the way the visual system processes visual information in the periphery of the visual field. When we fixate our eyes on a particular point, our visual system processes information in a way that prioritizes the information in the fovea, the central region of the retina where visual acuity is highest. As a result, the information in the periphery of the visual field is processed differently than information in the fovea.
The peripheral drift illusion typically involves a pattern of concentric circles or spirals that are arranged in a way that creates conflicting cues about the direction of motion. For example, the pattern may include alternating black and white regions that are arranged in a spiral pattern. When the image is fixated, the conflicting motion cues can create the impression of motion in the periphery of the visual field, even though the image itself is stationary.
The conflicting motion cues in the peripheral drift illusion can arise from several different sources. One source is the radial pattern of the concentric circles or spirals, which can create the impression of motion toward or away from the center of the pattern. Another source is the alternating contrast between different regions of the pattern, which can create the impression of motion in different directions.
The exact mechanisms behind the peripheral drift illusion are not fully understood, but it is thought to involve a complex interplay between different areas of the brain involved in visual processing. Some researchers have suggested that the illusion may involve interactions between the visual cortex and the neurons in the retina, while others have suggested that it may involve top-down processing from higher brain areas. Nonetheless, the peripheral drift illusion is a fascinating example of how the brain can create the illusion of motion where none exists.
Some Similar Illusions
There are several other illusions that are similar to the Spinning Spiral Illusion and also create the impression of motion in a stationary image. Here are a few examples:
Fraser spiral illusion: This illusion was discovered by British psychologist Sir James Fraser in 1908 and involves a spiral pattern of black and white wedges. When the image is fixated, the wedges appear to be rotating, even though the image is stationary.
Lilac chaser illusion: This illusion involves a series of 12 colored circles arranged in a circle on a black background. When the viewer fixates on the center of the circle and the outermost circle is removed, the remaining circles appear to rotate in a circle and a “lilac chaser” appears in the location where the removed circle was located.
Rotating snakes illusion: This illusion involves a series of overlapping circles and arcs of different colors arranged in a circular pattern. When the image is fixated, the overlapping patterns appear to rotate in a circle.
These illusions, like the peripheral drift illusion, rely on the visual system’s processing of motion cues in the periphery of the visual field to create the impression of motion. They are all fascinating examples of how the brain can create complex visual experiences from simple visual inputs.
Discovery of the Spinning Spiral Illusion
The Spinning Spiral Illusion is a type of peripheral drift illusion which was discovered by American psychologist and artist Roger Shepard in 1990. Shepard is well known for his work on visual perception and cognitive psychology, and he has made significant contributions to our understanding of how the brain processes visual information. The peripheral drift illusion is just one example of the many fascinating optical illusions that Shepard has helped to uncover over the course of his career.
In the examples, the shapes are all the exact same color. They only appear different back on the contrasting background colors.
The Munker illusion is a visual illusion in which two identical gray squares appear to be different shades of gray when they are placed on a patterned background. The illusion was discovered by German psychologist Paul Munker in 1970.
If you are interested in learning more, scroll down to learn more about it.
The Munker illusion is a visual illusion in which two identical gray squares appear to be different shades of gray when they are placed on a patterned background. The illusion was discovered by German psychologist Paul Munker in 1970.
The Munker illusion is created by the way that the visual system processes contrast information in the image. The patterned background surrounding the gray squares creates a gradient of contrast that changes the perceived brightness of the squares. The gray square on the lighter part of the pattern appears darker, while the gray square on the darker part of the pattern appears lighter.
The Munker illusion is particularly interesting because it challenges the idea that the perceived brightness of an object is solely determined by its physical luminance. Instead, the illusion demonstrates that the surrounding context can also influence the perception of brightness and contrast.
The Munker illusion is an example of a simultaneous contrast illusion, which occurs when the perception of an object is influenced by the characteristics of its surrounding context. Similar illusions include the famous checker shadow illusion and the White’s illusion. These illusions demonstrate the complex ways in which the brain processes visual information and highlights the importance of context in visual perception.
How does the Munker Illusion Work?
The Munker illusion is a visual illusion that occurs when two identical gray squares appear to be different shades of gray when they are placed on a patterned background. The illusion works by exploiting the way that the visual system processes contrast information in the image.
The patterned background surrounding the gray squares creates a gradient of contrast that changes the perceived brightness of the squares. Specifically, the squares on the lighter parts of the background appear darker, while the squares on the darker parts of the background appear lighter. This happens because the visual system is constantly trying to adjust for differences in lighting conditions in the environment, and it uses the surrounding context to help determine the true brightness of an object.
In the case of the Munker illusion, the visual system uses the surrounding pattern as a reference point to determine the brightness of the gray squares. The lighter parts of the pattern make the squares appear darker, while the darker parts of the pattern make the squares appear lighter, even though they are actually the same shade of gray.
The Munker illusion is a type of simultaneous contrast illusion, which occurs when the perception of an object is influenced by the characteristics of its surrounding context. Similar illusions include the checker shadow illusion and White’s illusion. These illusions demonstrate the complex ways in which the brain processes visual information and highlights the importance of context in visual perception.
Some Similar Illusions to the Munker Illusion
There are several other illusions that are similar to the Munker illusion and also rely on the concept of simultaneous contrast. Here are a few examples:
Checker shadow illusion: This illusion was discovered by Edward Adelson in 1995 and is similar to the Munker illusion in that it involves a checkerboard pattern that influences the perceived brightness of two identical gray squares. In this illusion, a shadow is cast over one of the squares, making it appear darker than the other square, even though they are the same shade of gray.
White’s illusion: This illusion, discovered by illusionist and psychologist James White in 1979, involves two identical gray circles placed on different colored backgrounds. The circles appear to be different shades of gray, with the one on the darker background appearing lighter and the one on the lighter background appearing darker.
Cornsweet illusion: This illusion involves a gradient of shading that makes a rectangle appear to have a three-dimensional bulge in the center. The illusion works by exploiting the way that the visual system processes changes in contrast, making the gradient appear to be a curved surface.
These illusions, like the Munker illusion, demonstrate how the brain uses surrounding context to interpret visual information and can lead to surprising and counterintuitive results.
Discovery of the Munker Illusion
The Munker illusion was discovered by German psychologist Paul Munker in 1970. Munker was interested in studying the effects of contrast on visual perception and developed the illusion as a way to explore how patterns and backgrounds can affect the perceived brightness of objects.
His discovery of the Munker illusion was an important contribution to the field of visual perception and has been studied extensively in the years since its discovery.
Are They Climbing the Stairs in this illusion? No, in fact, they aren’t moving at all. The stick figures aren’t moving or changing size at any point in the video.
The artists responsible for this design leveraged the principles of Illusory motion, specifically Beta Movement to create this awesome effect.
If you are interested in learning more about how this “Are They Climbing the Stairs Illusion” works, scroll down to learn more.
What is the Are They Climbing the Stairs Illusion?
The Are They Climbing the Stairs Illusion uses the principles of Illusory motion, specifically a concept known as Beta movement to create this effect.
Beta movement is a type of illusionary motion that occurs when two or more stationary images are presented in rapid succession, creating the perception of movement between them. The illusion was first described by German psychologist Max Wertheimer in 1912, as part of his research on the perception of motion.
Beta movement is sometimes referred to as apparent motion or phi phenomenon, and it is similar to other types of illusory motion, such as stroboscopic motion and the wagon-wheel effect. However, beta movement specifically refers to the perception of motion between two or more stationary images that are presented in succession, rather than the motion of a single object.
Beta movement can be created in a number of ways, including by using flashing lights or rapidly alternating images on a screen. The illusion works by exploiting the way that the brain processes visual information, as the brain interprets the rapid succession of images as a continuous movement, even if each individual image is static.
Beta movement has been studied extensively by psychologists and neuroscientists, as it provides insights into the complex ways in which the brain processes visual information and perceives motion. It has also been used in a variety of applications, including in the development of early animation techniques and in the design of visual displays for use in aviation and other high-stakes settings.
How does the Are They Climbing the Stairs Illusion Work?
The Are They Climbing the Stairs Illusion works using Beta movement which is an illusionary effect that creates the perception of motion between two or more stationary images that are presented in rapid succession. It works by exploiting the way that the brain processes visual information.
When two or more stationary images are presented in rapid succession, the brain interprets the sequence of images as a continuous movement, even though each individual image is static. This is because the brain is wired to look for patterns and connections in visual stimuli, and it uses a process known as temporal integration to create a sense of continuity between the different images.
Temporal integration occurs when the brain combines information from multiple sensory inputs over time to create a unified perceptual experience. In the case of beta movement, the brain integrates the information from each individual image into a single perceptual experience of motion.
The specific mechanisms behind beta movement are still not fully understood, but researchers have identified several key factors that contribute to the illusion. These include the duration of the individual images, the timing between them, and the visual characteristics of the images themselves, such as their brightness, contrast, and color.
Overall, beta movement is a fascinating phenomenon that sheds light on the complex ways in which the brain processes and interprets visual information. It has applications in a variety of fields, including psychology, neuroscience, and media technology.
Discovery of Are They Climbing the Stairs Illusion (Beta Movement)
The Are They Climbing the Stairs Illusion uses Beta movement which was first described by the German psychologist Max Wertheimer in 1912, as part of his research on the perception of motion. Wertheimer was interested in understanding how people perceive motion in still images, and he conducted a series of experiments using sequences of stationary images presented in rapid succession.
In one of his most famous experiments, Wertheimer presented two stationary images of dots on a screen, one after the other, with a brief interval of darkness between them. When the dots were arranged in a certain way, the sequence of images created the illusion of a single dot moving back and forth between the two locations.
Wertheimer called this phenomenon “phi movement” and noted that it was a type of illusory motion that occurred due to the way that the brain processes visual information over time. He later referred to this same effect as “beta movement,” and the term has been used ever since to describe the illusion of motion created by sequences of stationary images.
Wertheimer’s work on beta movement was groundbreaking and helped to lay the foundation for modern research on visual perception and sensory processing. His insights into the mechanisms behind the illusion of motion have been applied in a variety of fields, including psychology, neuroscience, and media technology.
The Circles Aren’t Moving illusion uses the principles of Illusory motion, also known as motion illusion, to create a cool effect. Illusory motion is a phenomenon in which static images or patterns appear to move or change position. These illusions can be created in a number of ways, such as through the use of contrasting colors or shapes that create the perception of movement, or through the use of repeated patterns that create a sense of motion.
One well-known example of an illusory motion is the famous “rotating snakes” illusion, in which a static image of a series of snakes appears to be rotating continuously. In reality, the image is static and the motion is an illusion created by the way the snakes are drawn.
Another example is the “wagon-wheel effect,” which occurs when a wheel appears to be moving slowly or even in the wrong direction when captured on film or video. This is due to the way that the camera captures individual frames and the speed at which the wheel is spinning relative to the frame rate of the camera.
Illusory motion can be a fascinating area of study for neuroscientists and psychologists, as it provides insights into the ways in which the brain processes visual information and perceives motion.
How does the The Circles Aren’t Moving Work?
The Circles Aren’t Moving uses illusory motion which works by exploiting the way that our brains process visual information. When we look at an image, our brains use a number of cues to interpret the visual scene, including color, contrast, shape, and motion.
When an image contains certain visual cues that are typically associated with motion, our brains may interpret the image as though it is in motion, even if it is actually static. This can occur due to a number of different mechanisms, including:
Contrast: When contrasting colors or shapes are placed next to each other, it can create the illusion of motion as our brains try to make sense of the differences between the two.
Repetition: Repeated patterns or shapes can create the perception of motion, as our brains interpret the repeated elements as a series of movements.
Peripheral vision: Objects that are located in our peripheral vision may appear to move or shift, even if they are not actually in motion, due to the way that our brains process information from this area.
Afterimages: When we stare at an image for a prolonged period of time, our brains may create an afterimage that appears to move or shift, even if the original image was static.
Overall, illusory motion is a fascinating area of study that sheds light on the complex ways in which our brains process and interpret visual information.
The phenomenon of illusory motion has been observed and studied for centuries, with some of the earliest recorded descriptions dating back to the 17th century. However, it is difficult to attribute the discovery of illusory motion to any one individual, as it has been studied and described by many researchers over the years.
One of the earliest known examples of an illusory motion was described by the Italian mathematician and astronomer Galileo Galilei in the early 17th century. Galileo observed that when two straight lines are placed next to each other, they can appear to be moving in a circular motion, due to the way that the brain processes the visual information.
Other notable researchers who have contributed to the study of illusory motion include Johann Wolfgang von Goethe, who wrote extensively about optical illusions in his book “Theory of Colours” published in 1810, and Hermann von Helmholtz, a German physicist and physician who conducted experiments on visual perception in the 19th century.
Today, illusory motion continues to be studied and explored by neuroscientists, psychologists, and other researchers interested in the mechanisms behind visual perception and sensory processing.
In this Reverse Spokes Illusion, the wheel is presented as a series of black and white alternating segments.
In realty, the spokes never move, but the changing hues make it appear that they do.
This illusion uses the the principles of apparent motion. If you are interested in reading more about how this Reverse Spokes Illusion works, scroll down to learn more about it.
In the Reverse Spokes Illusion, the wheel is presented as a series of black and white alternating segments, with each segment containing a single spoke that is slanted in the same direction as the rotation of the wheel.
This illusions demonstrations of the power of visual illusions to deceive our perception of reality. The illusion is often used as a visual demonstration of how our brains can be tricked into perceiving motion in a way that is different from the actual physical movement of an object.
How does the Reverse Spokes Illusion Work?
The Reverse Spokes Illusion works using the principles of apparent motion. Apparent motion is a perceptual phenomenon in which stationary objects appear to move due to the presentation of rapidly alternating images or stimuli. This illusion of motion is created when two or more images are presented in quick succession, with each image slightly different from the previous one.
For example, the classic example of apparent motion is the phi phenomenon, which occurs when two or more stationary lights are presented in a sequence, with each light turning on and off in a pattern. Even though the lights are not moving, they appear to be moving back and forth in a smooth motion, creating the illusion of motion.
Apparent motion is a fundamental phenomenon in the field of visual perception, and it is used in various applications, such as animation, film, and advertising. The study of apparent motion has contributed to our understanding of how the brain processes visual information and how it creates the perception of motion from static images.
Some Similar Illusions
There are several illusions that are similar to the Reverse Spokes Illusion in that they create the perception of motion where there is none. Here are a few examples:
Motion aftereffect: This is an illusion in which a stationary object appears to be moving in the opposite direction of a previously viewed moving object. It occurs because the neurons in the visual system that respond to motion become fatigued after prolonged exposure to a moving stimulus, causing them to respond less to the motion and creating the perception of motion in the opposite direction.
Autokinetic effect: This is an illusion in which a stationary point of light appears to move randomly in the dark. It occurs because the visual system relies on contextual information to determine motion and direction, but in the absence of external cues, the brain creates its own movement signals.
Rotating snakes illusion: This is an illusion in which a static image of a series of interconnected circles appears to be rotating, pulsating, or expanding. It occurs because the arrangement of the circles creates a pattern that stimulates the visual system and triggers a response that is similar to the response to actual motion.
Barberpole illusion: This is an illusion in which a striped pattern appears to be moving in a certain direction, even though the stripes themselves are stationary. It occurs because the pattern of diagonal stripes creates an ambiguous motion signal that can be interpreted in different ways by the visual system.
These illusions, like apparent motion, demonstrate the complex and often surprising ways in which our brains process and interpret visual information.
Discovery of the Reverse Spokes Illusion
The Reverse Spokes Illusion uses the phenomenon of apparent motion which was first discovered and studied by Max Wertheimer, a German psychologist who is known as one of the founders of Gestalt psychology. In 1912, Wertheimer conducted a series of experiments on the perception of motion, in which he presented subjects with a series of flashing lights in a certain pattern, and found that they perceived the lights as moving in a smooth, continuous motion.
Wertheimer called this phenomenon “phi phenomenon,” after the Greek letter phi, which is used to represent the ratio of two quantities that produce a pattern of motion. The phi phenomenon became one of the foundational discoveries of Gestalt psychology, which sought to understand how the mind organizes and interprets sensory information into meaningful patterns.
Since Wertheimer’s discovery, the study of apparent motion has been a major area of research in the field of visual perception, and has led to important insights into the way the brain processes motion and form information.
