How blind am I?
Mike Liberman at Language Log posts about people’s inattention to unexpected changes when doing a cognitively difficult task. This is also a problem for kids with learning disabilities, for whom[1] things like sounding out words is so difficult that they can’t pay attention to the content. This is well-discussed.
What I thought neat were the other videos: the person-change ones were amusing, but I was trying to catch the adding/removing of objects in photos, or the changing of a colour. It’s hard. Go look (Gradual changes to scenes is the subtitle) — they’re pretty fast. You can only watch it once, because starting it over makes the change too abrupt. (I got 3.)
I also can’t catch all 9 of the intentional cut changes in the second video.
[1] Only place I use it is after a preposition, but otherwise it sounds so wrong.
