Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

A temporal illusion is a distortion in the perception of time, which occurs when the time interval between two or more events is very narrow (typically less than a second). In such cases, a person may momentarily perceive time as slowing down, stopping, speeding up, or running backward.
Visual or Optical Illusions can be categorized according to the nature of the difference between objects and percepts. For example, these can be in brightness or color, called intensive properties of targets, e.g. Mach bands. Or they can be in their location, size, orientation or depth, called extensive.
The vestibular system is one of the major sources of information about one's own motion. Disorders of the visual system can lead to dizziness, vertigo, and feelings of instability. Vertigo is not associated with illusory self-motion as it does not typically make one feel as though they are moving; however, in a subclass of vertigo known as ...
Illusory motion, the appearance of movement in a static image Phi phenomenon , an illusion of movement created when two or more adjacent lights blink on and off in succession Stroboscopic effect , a phenomenon that occurs when continuous motion is represented by a series of short or instantaneous samples
Several tactile illusions are caused by dynamic stimulus sequences that press against the stationary skin surface. One of the best known passive tactile spatiotemporal illusions is the cutaneous rabbit illusion, in which a sequence of taps at two separated skin locations results in the perception that intervening skin regions were also tapped.
The difference between the Scintillating Grid Illusion and the Hermann Grid Illusion is that the former has dots already in place at the intersections, which is not the case for the latter. Since, at first sight, the graphs appear similar, the two illusions are occasionally confused.
The illusory truth effect (also known as the illusion of truth effect, validity effect, truth effect, or the reiteration effect) is the tendency to believe false information to be correct after repeated exposure. [1] This phenomenon was first identified in a 1977 study at Villanova University and Temple University.
