vision
You perceive motion even when nothing is moving.
The phi phenomenon is a distinct perceptual illusion of 'objectless' motion, whereas the illusion of motion in film (where a figure appears to travel between two points) is known as beta movement.
Beta movement, not the phi phenomenon, is the physiological basis for the perception of motion in film.
Movement is a narrative your brain builds from snapshots.
Where this comes from
- Study
- Max Wertheimer, 1912, Phi Phenomenon
- What the check found
- The claim misidentifies the phi phenomenon as the basis for film. That phenomenon is actually 'beta movement,' which involves the perceived motion of a figure, whereas phi is an objectless 'pure' motion sensation.
- Confidence
- Solid, with limits
