a common object. The results confirmed that decision-related neural processes occur during moments of unconscious thought while a person engages in a non-demanding task. The research showed that while distracted a subject isn’t maintaining one thought for a particularly long time, which in turn allows different ideas to float in and out of one’s consciousness—this sort of associative process leads to creative incubation. Ambient noise is another variable that is conducive to distraction. It has been proven that a moderate level of noise actually heightens creativity. Professor Ravi Mehta conducted a study to research the degree of distraction induced by various noise levels and their effect on creativity. The series of experiments show that a moderate level of ambient noise (70 dB) produces just enough distraction to induce processing disfluency, which leads to abstract cognition. These higher construal levels caused by moderate levels of noise consequently enhance creativity. Walking In 2014, a study found that walking increased creativity. Sleep and relaxation Some advocate enhancing creativity by taking advantage of hypnagogia, the transition from wakefulness to sleep, using techniques such as lucid dreaming. One technique used by Salvador Dalí was to drift off to sleep in an armchair with a set of keys in his hand; when he fell completely asleep, the keys would fall and wake him up, allowing him to recall his mind's subconscious imaginings. Thomas Edison used the same technique, with ball bearings. Meditation A study from 2014 conducted by researchers in China and the US, including the psychologist Michael Posner found that performing a short 30 minute meditation session each day, for seven days, was sufficient to improve verbal and visual creativity, as measured by the Torrance Tests of Creative Thinking, due to the positive effects of meditation on emotional regulation. The same researchers also showed in 2015 that short term meditation training could also improve insight-based problem solving (the type commonly associated with an "Ah-ha", or "eureka" type moment of realization) as measured by the Remote Associates Test.
