Rereading The Teenage Brain and I found this image which struck me as I had minutes earlier finished a conversation in which students debated the degree to which they can multi-task. I am gal to hear some students beginning to realize that they cannot perform as well when they are distracted by phone, friends, or other media when trying to learn or drive or do anything else that requires attention.
