"Baby Tetris": Study overview

Eligibility criteria

For babies ages 6 to 12 months who live in the United States.

Duration 15 minutes

We will provide a $5 (USD) Amazon gift card for eligible participants. We will send you the gift card within 3 days of participation. At the moment, this study is only open to families in the United States. Please understand that if you live outside the United States, we are unable to send you a gift card or use your data in the final sample. To be eligible for compensation we ask that you 1) provide a valid consent video (we will show you how!), 2) your child must be in the age range specified above and, 3) your child must be present during the study videos (but not necessarily the consent video), and live in the US. Your child does not need to finish the entire study in order to be eligible for compensation.

What happens

In this study, your baby will see two identical Tetris shapes on the screen; one on the left and one on the right. The shapes will appear and disappear, changing their orientation each time they reappear. On one side, the rotation will be possible. On the other side a mirror image will sometimes be presented. We are interested in which side your baby prefers to look at.

What we're studying

Spatial abilities such as mental rotation are important for understanding objects, reading maps, mathematical reasoning, and navigating the world. We are interested in whether babies can mentally rotate objects, such as Tetris-like blocks, because it will help inform us about how and when spatial abilities develop. We will test this by recording how infants look at images of rotated (as if seen from a different angle) and transformed blocks (e.g., a mirror image). Infants’ pattern of looking at these blocks informs us about their mental rotation abilities and provides us with a deeper understanding of how they perceive and think about the spatial properties of objects.
