Everybody in my family learned a long time ago that if I’m reading a book or sitting at the computer, you’re not going to get my attention unless you tap me on the shoulder or throw a shoe at me or something. I always figured it was just a side effect of my intense concentration (ahem), but now it looks like it may actually be a type of learning disorder. CAPD (Central Auditory Processing Disorder) occurs “when the ear and the brain do not coordinate fully.” I’ve got all the typical “at risk” behaviors other than the last four. (I was county spelling bee champion and I’ve never had a problem with language stuff.) And where did I learn of this potentially life-affecting diagnosis? A Slashdot comment.
