What is the term for the misperception of how much time has passed?

The term "temporal distortion" refers specifically to the misperception of time passing. This phenomenon can arise under various conditions, including stress, high altitudes, or in situations where an individual's attention is focused or distracted. Temporal distortion is significant in aerospace physiology, especially during flight, where pilots may experience altered perceptions of time due to the high-stress environment or unusual circumstances.

The concept is differentiated from related terms, such as "time lapse," which typically describes the actual passage of time within a given framework (e.g., time-lapse photography). "Chronological error" is not a recognized term in the context of psychological time perception. "Time dilation" pertains to the differences in time measurement as described by the theory of relativity, specifically how time can pass at different rates depending on speed and gravitational effects; this is not related to subjective perception of time. Thus, "temporal distortion" is the most accurate term for the described phenomenon.
