Does musical training improve how we monitor mistakes?
Amateur musicians are faster at identifying errors and processing conflicts in their brain, which helps them stay focused and avoid overreacting when they make mistakes.

Improved effectiveness of performance monitoring in amateur instrumental musicians
What they did
Researchers evaluated 36 young adults divided into four groups based on their lifetime hours of music practice: high, intermediate, low, or no practice. The participants completed a Simon task and a Stroop task while researchers recorded brain activity using 72 electrodes. The experiment analyzed reaction times, error rates, and brain signals associated with processing conflict and detecting mistakes.
What they found
Participants with more musical experience showed faster overall reaction times, with the group average dropping from 396 milliseconds for non-musicians to 347 milliseconds for highly practiced amateurs. EEG data showed that more practice was linked to larger brain waves associated with conflict detection and error monitoring. Interestingly, instead of overreacting to mistakes, experienced musicians showed less behavioral slowdown, with post-error slowing in the Stroop task decreasing for those with higher skill.
The limits
What it doesn't show
Because this study used a cross-sectional design comparing pre-existing groups, it cannot prove that musical practice directly caused the improvements in cognitive control. It is possible that individuals with naturally superior cognitive abilities are more likely to pick up and stick with an instrument. Additionally, the study was conducted on a highly specific sample of university students and employees, meaning these results might not generalize to the broader public or older age groups.
Key terms
- conflict monitoring theory
- A framework proposing that a brain region called the anterior cingulate cortex evaluates information processing conflicts and signals other areas to adjust cognitive control.
- Stroop task
- A cognitive test where participants must identify a physical feature of a stimulus, such as ink color, while ignoring a competing written word.
- Simon task
- A cognitive test where a stimulus is presented on the left or right side of a screen, and participants must respond to its shape while ignoring its spatial location.
- error-related negativity (ERN)
- An electrophysiological brain wave that peaks shortly after a person makes a mistake, serving as a neural marker of error detection.
- Gratton effect
- A behavioral phenomenon where the difficulty of dealing with a conflict on the current trial is reduced if the previous trial also contained a conflict.
- post-error slowing
- The tendency for people to react more slowly on the trial immediately following an incorrect response as they attempt to regain control.

Common questions
Why is it beneficial that musicians had less post-error slowing?
While slowing down after an error seems helpful, excessive slowing can actually disrupt ongoing performance, especially in fast-paced tasks like playing music. Musicians seem to quickly detect and resolve errors in the brain, allowing them to adjust smoothly without stalling their behavior.
Did the researchers study professional musicians?
No, they specifically looked at amateur musicians ranging from those with no practice to those with over 5000 hours of lifetime practice, showing that you do not need to be a professional to experience cognitive benefits.
What brain region is responsible for these cognitive control adjustments?
The study highlights the anterior cingulate cortex (ACC), which is highly active during conflict evaluation and error detection, as indicated by the ERN signals measured on the scalp.
How did the researchers measure the level of musical practice?
They used a detailed demographic music questionnaire where participants reported their lifetime accumulated music practice hours, years played, and starting age.
