Pretty interesting article about time perception
http://www.guardian.co.uk/science/2013/jan/01/psychology-time-perception-awareness-research"From infancy onwards babies must come to grips with a world marked by recurrent time patterns, learning the length of time, or duration, associated with the various actions they experience every day," says Professor Sylvie Droit-Volet, at the Social and Cognitive Psychology Laboratory (Lapsco) at Blaise Pascal University, Clermont Ferrand, France. "They react, become agitated or cry, when something they expect does not occur on time: when the mobile over their bed stops turning earlier than usual, when their mother takes too long preparing a feed," she adds.
Very young children "live in time" before gaining an awareness of its passing. They are only able to estimate time correctly if they are made to pay attention to it, experiencing time in terms of how long it takes to do something. "For a three-year-old, time is multifaceted, specifically related to each action," Droit-Volet explains. At the age of five or six a child is able to transpose the duration it has learned to associate with a particular action (pressing a rubber ball) to another (pulling on a lever). "They begin to realise that a single time continuum exists separately from individual actions," she adds.
