Doodling Can Trigger Brain’s Reward Pathways

A new study published in The Arts in Psychotherapy finds that engaging in simple expressions of judgment-free art, such as drawing, doodling, or coloring, activates the brain’s reward pathways.

“This shows that there might be inherent pleasure in doing art activities independent of the end results,” said study leader Girija Kaimal, Ed.D., assistant professor in the College of Nursing and Health Professions at Drexel University. “Sometimes, we tend to be very critical of what we do because we have internalized, societal judgements of what is good or bad art and, therefore, who is skilled and who is not.

“We might be reducing or neglecting a simple potential source of rewards perceived by the brain. And this biological proof could potentially challenge some of our assumptions about ourselves.”

For the study, researchers used fNIRS (functional near-infrared spectroscopy) technology to measure blood flow in the reward-related brain regions of 26 participants as they engaged in art-making activities, including coloring a mandala, doodling within or around a circle marked on a paper, and free-drawing. Each activity lasted three minutes with rests in between.

During all three activities, there was a measured increase in blood flow in the brain’s prefrontal cortex, compared to rest periods where blood flow went back to normal.

The prefrontal cortex helps regulate our thoughts, feelings and actions. It is also associated with emotional and motivational systems and part of the wiring for our brain’s reward circuit. So seeing increased blood flow in these areas likely means a person is experiencing feels related to being rewarded.

There were some distinctions between the activities in the data collected: Doodling in or around the circle had the highest average measured blood flow increase in the reward pathway compared to free-drawing (the next highest) and coloring. However, the difference between each form of art-making was not statistically significant, according to analysis.

“There were some emergent differences but we did not have a large-enough sample in this initial study to draw any definitive conclusions,” Kaimal said.

The researchers noted which participants in the study considered themselves artists so their results could be compared to non-artists. In that way, Kaimal and her team hoped to understand whether past experience played a factor in triggering feelings of reward.

Doodling seemed to initiate the most brain activity in artists, but free-drawing was observed to be about the same for artists and non-artists. Interestingly, the set coloring activity actually resulted in negative brain activity in artists.

“I think artists might have felt very constrained by the pre-drawn shapes and the limited choice of media,” Kaimal explained. “They might also have felt some frustration that they could not complete the image in the short time.”

Again, however, these results regarding artists versus non-artists proved statistically insignificant, which might actually track with Kaimal’s previous research that found experience level did not have a bearing on the stress-reduction benefits people had while making art.

Overall, though, the finding that any type of art-making led to an activation of feelings of reward are compelling, especially for art therapists who see art as a valuable tool for mental health.

In fact, based on surveys given to the participants after the activities were complete, respondents indicated that they felt more like they had “good ideas” and could “solve problems” than before making art. Participants even said they felt the three-minute time spans for art-making weren’t long enough.

“There are several implications of this study’s findings,” Kaimal said. “They indicate an inherent potential for evoking positive emotions through art-making — and doodling especially. Doodling is something we all have experience with and might re-imagine as a democratizing, skill independent, judgment-free pleasurable activity.”

Additionally, Kaimal felt that the findings of increased self-opinion were intriguing.

“There might be inherent aspects to visual self-expression that evoke both pleasure and a sense of creative agency in ourselves,” she said.
