I have a younger cousin, only a year old, whom really does entertain me quite a lot. It was very appealing to me while watching the video during lecture where the little boy with the screen in front of him and the car went by. I always play the game with him, which we now know as object permanence, by just simply ducking down below a table, and popping right back up, and he is just beside himself with laughter. No matter how many times or how long I would wait to pop back up from hiding behind the table, he still would just not be able to understand that I would keep popping back up. We also talked about children learning very quickly in lectures, such as the baby kicking its foot to move the toys above her head. Then the next time that she returns, she knows exactly what she has to do to get the toys to start moving, she doesn't have to start from ground zero. So what interests me referring to my little cousin and object permanence and cognitive development, it just surprises me that they can't learn about things like this when to us it really seems so simple, but at such a young age, well, before they hit age 7, they just don't understand it!
