Last night's Frontline "digital_nation" was very interesting. If you can see it on your local PBS, make the time. Or, you know, you could watch it online. If you can stay focused for 50 minutes. Part of the point of the show, is that if you're young, you probably can't.
And here's one thing I wanted to point out, some researching on multi-tasking. To give it away, no, you're not very good at it.
Unfortunately I can't find a link to the MRI scans of people reading a book versus people doing google searches. I know a lot of people don't believe me when I discuss that how we process images from transmitted light varies wildly from that of reflected light. Watch the show, you'll see the MRI maps. It's very striking. Also listen to the conversation about how "increased brain usage doesn't equal higher thought" (as was originally reported by the media). The brain doesn't work that way.
And some of the language segments they've been doing on NPR's news about how language structures our thoughts you should check them out.
