-------------------------------------------------TITLE: How chemical tags on a dopamine gene are linked to teen creativity
URL: https://www.psypost.org/how-chemical-tags-on-a-dopamine-gene-are-linked-to-teen-creativity/
Researchers have identified a link between molecular tags on a specific gene and creative thinking abilities in male adolescents. The study explored how biological mechanisms might influence brain function without altering the underlying genetic code. The results were published in Psychology of Aesthetics, Creativity, and the Arts.
Creativity is generally divided into two main cognitive processes. Divergent thinking is the ability to brainstorm multiple novel solutions to an open-ended problem. Convergent thinking is the ability to synthesize information to find a single correct answer to a well-defined problem. Both types of thinking rely on a neurotransmitter called dopamine, which helps the brain regulate attention, working memory, and response inhibition.
The genetic blueprint of the dopamine system varies from person to person. Researchers have studied how variations in the DNA sequence of dopamine-related genes relate to individual differences in creativity. However, the genetic sequence alone does not entirely determine how a gene behaves. A separate process called epigenetics also regulates how genes function.
Epigenetic mechanisms control how often or how strongly a gene is expressed, effectively acting like a volume dial. One primary epigenetic mechanism is DNA methylation, where tiny chemical tags called methyl groups attach to specific regions of the DNA molecule. These tags can turn a gene’s activity up or down in response to developmental stages or environmental influences like stress.
Xiaolei Yang of Qilu Normal University, alongside Jinghuan Zhang and Shun Zhang of Shandong Normal University, conducted a study to see if DNA methylation patterns on dopamine genes were associated with creative abilities in teenagers. Adolescence is a period characterized by intense brain development and high sensitivity to environmental factors. The researchers wanted to explore the epigenetic mechanisms that might be at work during this developmental window.
The research team recruited an initial group of 95 junior high school students in China, with an average age of about 13. The participants completed a battery of divergent thinking tests. Some tasks were verbal, asking students to list as many alternative uses as possible for common objects like a toothbrush. Other tasks were visual, requiring the students to look at ambiguous line drawings and list as many interpretations of the shapes as they could imagine.
The students were given four minutes to complete each specific task. The researchers scored the answers based on the sheer number of ideas generated, the variety of categories those ideas covered, and the originality of the responses.
To analyze the students’ epigenetic profiles, the researchers collected saliva samples. They extracted DNA and sequenced specific regions of six different genes known to be involved in dopamine signaling. The team calculated the average DNA methylation levels for each gene and compared these biological metrics against the students’ scores on the creativity tests.
In this first group, the researchers found that methylation levels on several genes were associated with different aspects of divergent thinking. Methylation of a gene called COMT was linked to the number of ideas and the flexibility of ideas generated in the visual tasks. Another gene, DRD4, showed an association with visual creativity and verbal flexibility. The most consistent association appeared with the MAOB gene, as its average methylation level was positively linked to all six measures of divergent thinking.
To see if these results could be replicated, the researchers recruited a second, slightly older group of 169 junior high school students. This second group completed the same types of divergent thinking tasks and also took a test designed to measure convergent thinking, which both samples had completed. The convergent thinking assessment was a Chinese remote association test. Participants saw three distinct Chinese characters and had to think of a fourth character that could combine with each of the original three to form meaningful words.
The participants were given 10 minutes to complete 20 test items, and their final score was based on the total number of correct answers. The researchers again collected saliva samples to sequence the DNA methylation patterns of the same six dopamine genes.
The results from the second group revealed an association between the DAT gene’s methylation levels and all six divergent thinking scores. The MAOB gene again showed a strong association with all six divergent thinking scores. The MAOB gene’s methylation level was also associated with better performance on the convergent thinking test in this second group.
When the researchers looked closer at the MAOB gene data from both groups, they noticed a distinct pattern. The association between MAOB methylation and divergent thinking was only present in male adolescents.
The MAOB gene, short for monoamine oxidase B, carries the instructions for an enzyme that helps break down dopamine in the brain. It is located on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome.
Because females have two copies of the X chromosome, one is typically silenced during development to balance out the genetic dosage. This silencing process heavily involves DNA methylation. The researchers suspect that this fundamental biological difference, along with the influence of sex hormones, might explain why the link between MAOB methylation and creativity appeared only in males.
The location of the methylation tags on the MAOB gene also provided structural clues. The association with creativity was found in the main body of the gene, rather than the promoter region that typically acts as the gene’s primary on and off switch. High methylation in a gene’s body is often associated with a medium level of overall gene expression.
Previous studies suggest that dopamine activity follows an inverted U-shape curve when it comes to creativity. Too much or too little dopamine can hinder cognitive flexibility, but a moderate amount promotes optimal creative performance. The researchers hypothesize that a medium level of MAOB expression might help maintain the moderate, balanced levels of dopamine activity required for creative problem-solving.
The study has several limitations that should be noted. The number of participants in both groups was relatively modest. A smaller number of subjects can make it harder to detect weak associations or increase the risk of false positives. The initial associations seen with the COMT, DRD4, and DAT genes were not consistent across both groups.
The researchers relied on saliva samples rather than brain tissue to measure DNA methylation. While saliva is a common and accessible proxy in genetic studies, methylation patterns can vary between different tissues in the body. It is not fully known how closely saliva methylation matches the exact patterns found inside the human brain.
The findings are based entirely on young adolescents. Epigenetic patterns change dynamically as people age. The relationship between dopamine gene methylation and creativity might look completely different in adults or younger children.
The research acts as a starting point for generating new hypotheses rather than providing absolute conclusions. It offers a glimpse into how the environment might biologically embed itself into our cognitive processes through epigenetics. Future studies will need to follow larger groups of people over time to see if environmental factors like stress directly influence these epigenetic shifts.
The study, “The Association Between Dopaminergic Gene Methylation and Adolescent Creativity,” was authored by Xiaolei Yang, Jinghuan Zhang, and Shun Zhang.
