Eligibility criteria

For babies age 7 to 9 months.

Duration 10 minutes

PLEASE NOTE: this study is currently volunteer-based and not providing compensation. We will send you a customized non-monetary certificate featuring your child scientist roughly a week after your participation.

What happens

In this study, your baby will hear different numbers of sounds, and watch movies with different numbers of shapes in them. We are interested in how well babies can match the numbers they hear to the numbers they see.

What we're studying

Can babies connect how many things they see to how many sounds they hear? And how does this ability develop over the first few months of life? We address this question by looking at how babies at different ages react to images and sounds of different quantities. Findings from this study will tell us more about how babies abstract number information from the busy and complex world around us.
