My personal experience is completely opposite. When I was young I would naturally focus and block out noise even though my environment was chaotic and I got good grade without trying. But as I grew older, since high school the natural ability was lost and my performance and grades suffered. When I start working the mindfulness and meditations practices helped me tremendously and I would felt like I can go back to my focus and productive mode easily and regained my performance.
