Depressed? Thinking faster may elevate your mood according to Cognitive Daily.
One question this study doesn't answer is what, precisely is occurringin the brain when we "think faster." Are neurons firing more rapidly? Are we literally moving faster from thought to thought, keeping each thought in our minds for a shorter period of time? Perhaps the effort of reading quickly simply distracts readers from negative thoughts -- the literal "speed" of thought doesn't increase, but rather, the brain is occupied with a difficult task and so doesn't have the ability to process other tasks, such as harboring negative feelings.
Still, as the authors point out, it does demonstrate quite effectively that processing negative language more quickly doesn't appear to intensify the effect of the language -- in fact the reverse occurs, and mood improves when we read faster.
Distractions - in my case, woodworking - can also elevate mood. So the result from processing negative language faster (see the charts at Cognitive Daily) does raise an interesting question: what should we expect from language? What is its effect?
I honestly have no idea why faster reading appears to improve mood. But like the pleasure of producing tissue-thin waves of Walnut or Cherry from a jack plane, it seems to me that the language effect has as much to do with the cooperative act between sense and intellect, and like reading, is more than mere words alone can say.
