The kappa effect is a perceptual illusion in which the amount of time judged to have passed between two sensory stimuli is distorted by the spatial or physical distance between them. When the distance between successive stimuli is large, observers tend to overestimate the time that elapsed between them, and when the distance is small, they tend to underestimate it, even when the true time interval is held constant. The effect has been demonstrated with visual, auditory and tactile stimuli, showing that the perception of elapsed time is not independent of spatial information.

Lead section
The kappa effect or perceptual time dilation is a temporal perceptual illusion that can arise when observers judge the elapsed time between sensory stimuli applied sequentially at different locations. In perceiving a sequence of consecutive stimuli, subjects tend to overestimate the elapsed time between two successive stimuli when the distance between the stimuli is sufficiently large, and to underestimate the elapsed time when the distance is sufficiently small.
