Music develops our attention and concentration in many different ways.
Today I’d love to speak about the ability to pay attention to auditory stimuli that musicians’ brain develops and why this is so important.
Our daily life subjects our brains to a huge amount of sound stimuli simultaneously. Our brain performs very complex operations to discriminate the sounds it wants to pay attention to, using cognitive functions related to the temporal lobe and the frontal lobe.
The ability to discriminate sound stimuli allows us, for example, to be able to direct our attention towards the sound of our friend’s voice in a noisy room.
Musicians can discriminate between different auditory stimuli better than non-musicians.
The Kraus lab at Northwestern* performed an EEG study and found that musicians had better auditory attention scores than non-musician counterparts when listening to various sources of speech. The main difference was presented in the musicians’ prefrontal cortex. The latter is often associated with attention and control, as well as personality and values.
The most fascinating part of this study was that the magnitude of the effect correlated to how long the musicians had played music.
People with more years of musical training had a prefrontal cortex that “paid better attention” than people who had fewer years of musical training. It seemed that people who had spent more time training their brains via musical study had prefrontal cortexes that were better at locking their attention.
Playing music alters the prefrontal cortexes and therefore influences the capabilities to pay attention to other activities in life. Being able to attend to different auditory stimuli can be helpful for a multitude of people; students might better be able to focus in school, sports players might hear each other over the sounds of the stadium and ground crew at airports might hear orders more accurately over the sound of airplane engines.
So, it seems like the time to recognise the importance of music in our daily life has finally come.
