The beta movement illusion is a visual illusion in which a series of static images, such as a filmstrip or flipbook, appears to be in motion when viewed in rapid succession.
This illusion is caused by the persistence of vision, which is the phenomenon by which the human brain continues to perceive a visual stimulus for a short period of time after it has been removed.
This allows the brain to perceive multiple static images as a single moving image, creating the illusion of motion.

How does the Beta Movement work?
The beta movement illusion works by exploiting the persistence of vision phenomenon in the human visual system. Persistence of vision refers to the way the brain continues to perceive a visual stimulus for a short period of time after it has been removed. This allows the brain to perceive multiple static images as a single moving image, creating the illusion of motion.
In the case of the beta movement illusion, a series of static images are presented in rapid succession, such as a flipbook or filmstrip. The images are typically of an object or scene in which one or more elements have been slightly altered from one frame to the next. When viewed quickly, the brain perceives the series of images as a single moving image, creating the illusion of motion.
The speed at which the images are presented is also important, as the faster the images are presented, the stronger the illusion of motion becomes. This is why the beta movement illusion is often used in animation and film, as it allows for the creation of the illusion of motion using a series of static images.

Illusions like Beta Movement
The beta movement illusion is a type of kinetic illusion. Kinetic illusions are visual illusions that involve the perception of movement, despite the absence of any actual movement in the stimulus. The beta movement illusion is specifically a type of motion aftereffect, which is a phenomenon in which a stationary stimulus is perceived as moving after it is no longer present. The beta movement illusion is a specific example of motion aftereffect, which is created by the rapid presentation of a series of static images.
It’s also considered a form of phi phenomenon, that is, the perception of motion when two or more stimuli are presented in rapid succession.
The following are some illusions that are related to the Beta Movement
Troxler’s fading, also known as Troxler’s effect, is a phenomenon in which a stationary visual stimulus, such as a dot or a shape, disappears from perception after a certain period of time.
The Phi phenomenon is the illusion of movement created by the rapid succession of static images or light sources.
The Rotating Snakes is a peripheral drift illusion that consists of a grid of shapes, with some of them appearing to be rotating or undulating. The illusion is created by the interaction of the shapes with the neural processing of the visual system.
The Moiré pattern illusion: This illusion is created by superimposing two similar patterns on top of each other, such as a grid of lines or circles. The resulting pattern appears to be moving or changing.
The Scintillating Grid Illusion, in which a grid of black and white squares appears to pulsate or “breathe” when viewed from the periphery of the image.
The Hermann Grid Illusion, in which the intersections of a white grid on a black background appear to be gray, even though they are actually the same color as the background.
The Zöllner Illusion, in which parallel lines appear to be tilted or bent when intersected by diagonal lines.
The Fraser Spiral Illusion, in which a pattern of short, curved lines appears to form a spiral.
The Hering Illusion, in which two straight lines appear to be curved due to the presence of surrounding lines.
The Café Wall Illusion is a visual illusion that is created by a grid of alternating light and dark horizontal and vertical lines. The lines appear to be bent or tilted, even though they are actually straight.
These illusions are usually caused by the way our eyes process visual information and the way the brain interprets it. They can also be caused by the interaction of different visual elements, such as lines and angles, in the image. They are often used in research on visual perception and the neural basis of perception.
Discovery of the Beta Movement
The beta movement illusion is a well-known phenomenon that has been studied and described by many researchers over the years.
The earliest known description of the beta movement illusion was made by the German physiologist Ewald Hering in the late 19th century. He observed that the perception of motion can be created by the rapid presentation of a series of static images and called it the “apparent movement.”
However, the term “beta movement” was first coined by the American psychologist Joseph Jastrow in 1899, in his article “The Psychology of the Flip-Book.” Jastrow was one of the first researchers to systematically study the beta movement illusion and to describe the specific conditions under which it occurs.
In summary, While Ewald Hering was one of the first to describe the phenomenon of apparent movement, Joseph Jastrow was credited with coining the term “beta movement” and was one of the first researchers to systematically study the beta movement illusion.
