When it's five o'clock, people leave their office. The length of the workday, for many workers, it defined by time. They leave when the clocks tells them they're done.

    These days, the time is everywhere: not just on clocks or watches, but on cellphones and computers. That may be a bad thing, particularly at work. New research shows that clock based work schedules hinder creativity.

    Clock-timers organize their day by blocks of minutes and hours. For example: a meeting from 9 a. m. to 10 a. m, research from 10 a. m to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.

    What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities from project planning, holiday shopping, to yoga-by time or to-do list to measure how they performed under “ clock time” vs “ task time”. They found clock timers to be more efficient(有效率的) but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.

    The researchers argue that task-based organizing tends to be undervalued and under-supported in the business culture. This might be a small change to the way we view work and the office, but the researchers argue that it challenges a widespread characteristic of the economy; work organized by clock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when performing a job that requires more creativity. It'll make those tasks easier, and the task-doers will be happier.
