Moments of Creative Insight May Lead to Future Moments of Creative Insight

Node Smith, ND

Creativity is one of humanity’s most distinctive abilities and enduring mysteries. Innovative ideas and solutions have enabled our species to survive existential threats and thrive. Yet, creativity cannot be necessary for survival because many species that do not possess it have managed to flourish far longer than humans.

So, what drove the evolutionary development of creativity?

A new neuroimaging study led by Yongtaek Oh, a Drexel University doctoral candidate, and John Kounios, PhD, a professor in Drexel’s College of Arts and Sciences and director of its Creativity Research Lab, points to an answer.

“Aha moments” may trigger burst of activity in brain’s reward system

The study, recently published in NeuroImage, discovered that, in some people, creative insights, colloquially known as “aha moments,” trigger a burst of activity in the brain’s reward system — the same system which responds to delicious foods, addictive substances, orgasms and other basic pleasures.

Individuals who experience insight-related neural rewards are likely to engage in further creativity-related activities

Because reward-system activity motivates the behaviors that produce it, individuals who experience insight-related neural rewards are likely to engage in further creativity-related activities, potentially to the exclusion of other activities — a notion that many puzzle aficionados, mystery-novel devotees, starving artists and underpaid researchers may find familiar, according to Kounios.

“The fact that evolution has linked the generation of new ideas and perspectives to the human brain’s reward system may explain the proliferation of creativity and the advancement of science and culture,” said Kounios.

Study focused on the phenomenon of aha moments, or insights, as prototypical instances of creativity

The study focused on the phenomenon of aha moments, or insights, as prototypical instances of creativity. Insights are sudden experiences of nonobvious perspectives, ideas or solutions that can lead to inventions and other breakthroughs. Many people report that insights are accompanied by a mind-expanding rush of pleasure.

Team recorded people’s high-density electroencephalograms (EEGs) while they solved anagram puzzles

The team recorded people’s high-density electroencephalograms (EEGs) while they solved anagram puzzles, which required them to unscramble a set of letters to find a hidden word. Such puzzles serve as small-scale models of more complex forms of problem-solving and idea generation. They noted which solutions were achieved as insights that suddenly popped into awareness, in contrast to solutions that were generated by methodically rearranging the letters to look for the right order.

Test subjects also filled out a questionnaire that measured their “reward sensitivity”

Importantly, the test subjects also filled out a questionnaire that measured their “reward sensitivity,” a basic personality trait that reflects the degree to which an individual is generally motivated to gain rewards rather than avoid losing them.

Here’s what the test subjects showed

The test subjects showed a burst of high-frequency “gamma-band” brainwaves associated with aha-moment solutions. However, only highly reward-sensitive people showed an additional burst of high-frequency gamma waves about a tenth of a second later. This second burst originated in orbitofrontal cortex, a part of brain’s reward system.

Study shows the following

The study shows that some people experience creative insights as intrinsically rewarding. Because this reward-related burst of neural activity occurred so quickly after the initial insight, only a tenth of a second, it did not result from a conscious appraisal of the solution. Rather, this fast reward response was triggered by, or integrated with, the insight itself.

Low-reward-sensitivity test subjects & study suggestions

Low-reward-sensitivity test subjects did experience nearly as many insights as the high-reward-sensitivity ones, but their insights did not trigger a significant neural reward response. Thus, neural reward is not a necessary accompaniment to insight, though it occurs in many people.

This study suggests that measurements of general reward sensitivity may help to predict who will practice, develop and expand their creative abilities over time.

His mission is serving relationships that support the process of transformation, and that ultimately lead to healthier people, businesses and communities. His primary therapeutic tools include counselling, homeopathy, diet and the use of cold water combined with exercise. Node considers health to be a reflection of the relationships a person or a business has with themselves, with God and with those around them. In order to cure disease and to heal, these relationships must be specifically considered. Node has worked intimately with many groups and organizations within the naturopathic profession, and helped found the non-profit, Association for Naturopathic Revitalization (ANR), which works to promote and facilitate experiential education in vitalism.
