A study on music activity attempted to demonstrate the benefits of musical training on the performance of non-musical tasks. Non-musicians were randomized to receive eight weeks of either musical rhythm or word search training. Memory for faces was assessed before and after exercise, while electroencephalography data was recorded to determine changes in brain activity.
The results showed that only musical rhythm training improved face memory, which was associated with more significant activity in the upper parietal region of the brain when encoding and retaining faces. Thus, musical rhythm training may improve facial memory by facilitating how the brain encodes and contains memories.
That sounds like an excellent excuse to start learning a musical instrument!
