Because the lilac dots only appear in our peripheral vision, their movements are not significant enough to engage new neurons of our visual system, and thus appear to fade away entirely. As researchers would later discover, our reactions to illusions can be even more complicated than the early pioneers realised.
The illusion operates by taking advantage of our perceptions of light constancy. Hering The Hering illusion, says Changizi, features radial lines that give the illusion of movement, similar to the scene we see as we move forward in the real world.

Unfamiliar objects, however, do not always follow the rules of shape constancy and may change when the perspective is changed.
Seeing, then, is certainly not always believing. Some of these elements have been successfully incorporated into quantitative models involving optimal estimation or Bayesian inference. Illusions in a scientific context are not mainly created to reveal the failures of our perception or the dysfunctions of our apparatus, but instead point to the specific power of human perception.
