Time perception is a field of study within psychology and neuroscience. It refers to the sense of time, which differs from other senses since time cannot be directly perceived but must be 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. Some researchers attempt to categorize people by how they differ in their perception of time (see "Personality characteristics" below).
Pioneering work, emphasizing species-specific differences, was done by Karl Ernst von Baer. Experimental work began under the influence of the psycho-physical notions of Gustav Theodor Fechner with studies of the relationship between perceived and measured time.

Famous quotes containing the words time and/or perception:
“Nothing ever prepares a couple for having a baby, especially the first one. And even baby number two or three, the surprises and challenges, the cosmic curve balls, keep on coming. We can’t believe how much children change everything—the time we rise and the time we go to bed; the way we fight and the way we get along. Even when, and if, we make love.”
—Susan Lapinski (20th century)
“And one may say boldly that no man has a right perception of any truth who has not been reacted on by it so as to be ready to be its martyr.”
—Ralph Waldo Emerson (1803–1882)
