Cognitive Daily has a great review of an intriguing study that suggests that thinking quickly could boost your mood.
People with mania, a state of uncontrollably ‘high’ mood, often say they have racing thoughts, and people with depression sometimes feel as if their thoughts are slowed, impaired or sluggish.
They asked participants to read text at different speeds then asked them to rate their mood afterwards. People who had read text at the fastest speeds, reported a lift in mood.
The study involved some more comprehensive investigations, and there’s more at Cognitive Daily if you want the nitty gritty.
