Do Babies Prefer Real Human Faces?

Do Babies Prefer Real Human Faces?

Language Learning and Multisensory Brain (LLAMB) Lab (Haskins Laboratories, Yale University)

Who Can Participate

for babies ages 6 months to 1 year!

What Happens

Your baby will see two faces on a screen saying “ba”. We’re interested in seeing which of these two faces your baby prefers. There’s nothing you have to do other than let these videos play while we record your baby's looking. Please note: for this study, you will need a high chair or stroller for your baby to sit in!

What We're Studying

This study investigates babies’ preferences when given a choice between real human faces and artificial, computer-generated human faces. This is one way of exploring whether babies’ nearly exclusive exposure to human faces makes them prefer real human faces. We have investigated this question before, but in a controlled lab setting. Now, we are using Lookit to see if this phenomenon still exists in a new and less controlled environment like your home by measuring how much time your baby looks at each of the faces on the screen. We are interested in investigating whether infants prefer real human faces over artificially created ones because this will allow us to find out whether we are born with such a preference or whether we acquire such a preference through our daily exposure to human faces when we are babies.

After you finish the study, we will email you a $5 Amazon gift card within approximately three business days. To be eligible for the gift card your child must be in the age range for this study, you need to submit a valid consent statement, and we need to see that there is a child with you. But we will send a gift card even if you do not finish the whole study or we are not able to use your child's data. There are no other direct benefits to you or your child for participating, but we hope you will enjoy the experience. If you participate again with another child in the age range, you’ll receive one gift card per child.
