Peek-a-Boo is one of those games every parent loves to play with their children. I have played it many times with my nephew, and he just laughs and laughs. Every time my face would pop out from behind my hands, a huge grin would brighten up my nephew’s whole face. What makes this game so fun to a baby? It’s the lack of object permanence. When parents block their face with their hands while playing a game of peek-a-boo with their babies, their babies actually think that their parents have disappeared. They no longer exist. That is why babies think it is so funny when their parents re-appear.  It is like they appeared out of thin air. When a baby reaches the age of 8 to 12 months they develop object permanence, meaning that if a parent puts their face behind their hands, their child is still going to know that they exist even when they cannot see them. Now when I play hide-and-go-seek with my nephew he knows that I still exist and he needs to come find me. Mastering object permanence is a major advance in cognitive development. Who knew that a simple game could test your child’s advances in cognitive development!?

I never really thought about the children's games as actually being beneficial to their development. To me, they were just fun games. Now that I understand what object permanence is all about, those games have more meaning. I remember when my kids, who are now 24 and 20, were this age. Peek-a-boo was a fun game to play with them. It is interesting to see how they followed along these developmental paths.

  1. Kelsea, Holli emailed me a picture related to object permanence. I thought I would attach it to your post.

  2. I think that object permanence is a really cool thing with babies. It is so neat that they actually think you are gone when you cover up your face. When they finally develop object permanence and understand that you aren't really gone when you cover up your face during peek a boo, it must almost open up a whole new world of understanding to them. -Elisabeth Arnold
