What's counting for babies? 4.0

For babies age 14 to 18 months.

In this study, your baby will watch different numbers of toys being pointed at and labeled in different ways (such as "one, two, three" or "dax, dax, dax"). We are interested in how babies react to different types of activities that resemble counting. This is a new version of "What's counting for babies" - if eligible, your child can participate even if you've done a previous version of this study! You will need a high chair or stroller for this study.

Babies hear count words as early as a few months of age. But do babies know that counting is about quantity? And if so, what about counting (e.g., does it have to be "one, two, three"?) draws babies' attention to quantity? Your baby's reaction to our "counting" videos will tell us what types of activities draw babies’ attention to quantities, and will ultimately help scientists understand where our concept of counting comes from.
