Read here about chronoception, the reception or construction of time information, and its relation to issues of scale.


Chronoception or time perception refers to the sense of time, which differs from other senses in the ratio of brain vs. physical receptor, since time is not directly perceived but is mostly reconstructed by the brain. Humans can perceive relatively short periods of time, in the order of milliseconds, and also durations that are a significant fraction of a lifetime. Human perception of duration is subjective and variable. The kappa effect is a form of temporal illusion verifiable by experiment whereby time intervals between visual events are perceived as relatively longer or shorter depending on the relative spatial positions of the events. In other words: 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.
