As chronostasis (from Greek χρόνος, chronOS, "time" and στάσις "congestion", "congestion") is the perception deception indicates that the first sensory impression of eye movement appears subjectively increased. The best known is the impression that when looking at a watch, the first second appears longer than the following.

Studies have shown that this illusion is probably created by the fact that the brain constructs a continuous perceptual experience despite the rapid eye movements (saccades) by lengthening the perception over time via the eye movement. Although this effect occurs with every eye movement, it is only apparent when looking at an external timer.

The effect is not only limited to visual perception, but also occurs when hearing.
