Illusions of time
A temporal illusion is a distortion in sensory perception caused when the time between the occurrence of two or more events is very short (typically less than a second). In such cases a person may misperceive the temporal order of the events. The kappa effect is a form of temporal illusion verifiable by experiment[16] whereby time intervals between visual events are perceived as relatively longer or shorter depending on the relative spatial positions of the events. In other worlds, the perception of temporal intervals appears to be directly affected, in these cases, by the perception of spatial intervals. The Kappa effect can be displayed when considering a journey made in two parts that take an equal amount of time. Between these two parts, the journey that covers more distance will appear to take longer than the journey covering less distance, even though they take an equal amount of time.
