For individuals, the most marked is the strengthening of "alpha waves," which have a hypnotic and stultifying effect on the brain. There is also a significant weakening of beta waves, which represent liveliness and quick thinking. This is especially apparent in children.
對個人來說，最明確的就是收看電視時，人腦中有催眠、靜止作用的阿法波（α waves）增強，而代表活躍、快速思考的貝塔波（β waves）則大幅減弱，這在兒童身上尤其明顯。
