Existing research demonstrates that experiencing positive feelings or states makes us feel like time is passing faster than negative feelings and states do. But, as some researchers observe, not all positive states are created equal. Sometimes we experience feelings of contentment or serenity. These feelings are certainly positive ones, but they aren’t very high in what researchers call ‘approach motivation’ – they don’t make us want to go out and pursue or achieve something. Feelings of desire or excitement, on the other hand, are very high in approach motivation – desire and excitement motivate us to go forth and conquer.
“Although we tend to believe that time flies when we’re having a good time, these studies indicate what it is about the enjoyable time that causes it to go by more quickly,” says Gable. “It seems to be the goal pursuit or achievement-directed action we’re engaged in that matters. Just being content or satisfied may not make time fly, but being excited or actively pursuing a desired object can.”
This is consistent with the concepts of “flow” and being “in the zone”.
