Television tends to engage the right cerebral hemisphere. Like computers, it uses several attributes (images, backlit screens, and speed) that tend to engage the right cerebral hemisphere and generate emotional involvement…in contrast to words (especially words employed in business communications) that involve the left cerebral hemisphere. (Restak, Richard, MD. Mozart’s Brain and the Fighter Pilot. NY: Harmony Books, 2001, pp 136-137)
