The participants were conservatory students, and music is a technical field, so I wonder if this applies at all to other technical fields that require a lot of concentration. It looks like it was a very small study.
Musical training produces lasting improvements to a cognitive mechanism that helps individuals be more attentive and less likely to be distracted by irrelevant stimuli while performing demanding tasks. According to a new study appearing in the journal Heliyon , published by Elsevier , trained musicians demonstrate greater executive control of attention (a main component of the attentional system) than non-musicians. Notably, the more years of training musicians have, the more efficient they are at controlling their attention.
