Animal Hide-and-Seek!

Animal Hide-and-Seek!

Infant and Child Development Center (Northwestern University)

Who Can Participate

For babies aged 11.5 to 12.5 months who are learning English as their first language and who reside in the United States

What Happens

In this study, your baby will watch short videos filled with cute, stuffed animals. Each of these animals will hide behind a screen, and your baby will watch as the screen is then raised. We will record how interested your baby is in looking at what animal comes out from behind the screen.

What We're Studying

Babies pay close attention to how objects behave in the world and know that objects cannot just seemingly change their identity for no reason. Here, we are asking if babies still remember that an object is the same one even if it disappears and reappears from view. This study will help us understand how babies start to use their knowledge about objects to respond to events involving those objects.
