A piece in today’s Wall Street Journal describes how the perception of time differs dramatically between women and men. The piece considers the differences between different activities, and notes that childcare in particular places significant stresses on time usage and sleep deprivation. Mothers have been found to assume a disproportionate number of time-sensitive domestic tasks, whether it’s getting their children dressed for school or off to sports practice. Sociologists Annette Lareau and Elliot Weininger call these activities "pressure points," or "non-negotiable demands", which make life more complex and frenetic. Sociologists Shira Offer and Barbara Schneider have found that the result of all these situations is that mothers spend 10 extra hours a week, on average, multitasking than do fathers. The result of these "pressures points" and "non-negotiable demands" is a very different subjective perception of time’s passing.
