The findings could be used to help develop new methods of brain training for treating depression and anxiety.
Doing simple maths in your head has been linked to better emotional health by a new study.
The reason is that the same areas of the brain are involved in both emotional processing and mental maths.
The research could be the first step towards creating brain training exercises to help anxiety and depression.
Mr Matthew Scult, the study’s first author, said:
“Our work provides the first direct evidence that the ability to regulate emotions like fear and anger reflects the brain’s ability to make numerical calculations in real time.”
The study involved brain scans of 186 people who were doing mental math problems from memory.
Researchers were interested in an area of the brain called the dorsolateral prefrontal cortex.
This area has been linked to depression and anxiety.
When people learn cognitive-behavioural therapy, more activity is seen in this area of the brain, suggesting it is critical in dealing with emotional problems.
The researchers found that more activity in this region was linked to more emotional adaptability.
Mr Scult said:
“We don’t know for sure why that is, but it fit into our hypothesis that the ability to do these more complex math problems might allow you to more readily learn how to think about complex emotional situations in different ways.
It is easy to get stuck in one way of thinking.”
The more activity was seen in the dorsolateral prefrontal cortex, the lower people’s levels of depression and anxiety.
It’s not yet clear if mental maths really causes better emotional control.
However, Mr Scult said:
“We hope, with these and future studies, that we can inform new strategies to help people regulate their emotions, and to prevent symptoms of anxiety and depression from developing in the first place.”
The study was published in the journal Clinical Psychological Science (Scult et al., 2016).
Hello, and welcome to PsyBlog. Thanks for dropping by.
This site is all about scientific research into how the mind works.
It’s mostly written by psychologist and author, Dr Jeremy Dean.
I try to dig up fascinating studies that tell us something about what it means to be human.
