What is Phi phenomenon?This theory was introduced by Max Wertheimer and Barbara Fisher in the same year that William Horner introduced the theory of persistence of vision in 1912. The Phi phenomenon states that the it is a optical illusion from motion between two separate objects, it says that the eyes work as receptor just like a camera and the brain does all the work while the Persistence of vision states that the eye does all the work and causes the illusion of movement, e.g. When lights are flashing at rapid succession in different places without actual motion the brain will thing that the lights are moving and changing places.What is the Gestalt theory?This theory as introduced by a group of psychology in 1920. There are two different types of this theory one is psychology and the other on systematically. The theory states that when you look at an optical illusion you will be able to see more than one image. an example of this is the image below where you can see a young women but if you look closely that same image is also an image of a old womenMy personal opinion I think that the Phi phenomenon is the best theory and the one I believe in because the brain does all the work, everything that you hear, see, touch and feel has to go through the brain first, the brain is the one that creates the illusion while the eyes only see it just like when you look through a camera.
