Sounds like it was way more fun than our study. For us, they flashed various patterns of red dots on a screen. The idea is that babies pay attention to something new, but after a time are bored with something old. The trick was to measure whether Ellie saw the changes in dot size and placement as new or old. She was fascinated at first, predictably, and bored at the end. I can't remember the middle very clearly. She was mostly interested in where the tester guy went when he wasn't right in the room with us.
