How do young children learn new words?
eye tracker studyThis study focuses on infant attention and language development between 10-18 months. Also, we are studying how mothers and fathers respond to their infants during play interactions with familiar and novel objects. After playing with these objects, children will be asked to choose which object a label is referring to. 




eye trackerFor all visits, you and your child will wear a head-mounted eye-tracker so we can see where you are both looking while you play. 





How do infants communicate with their parents?
InCoDe Playroom
One study focuses on infant communication behaviors in social interactions, such as what types of vocalizations or gestures infants produce, where they are looking when they vocalize or point and how parents respond to these behaviors. In this study, infants (aged 10 and 12 months) and parents play with a variety of toysfor 30 minutes in a large playroom as they would at home. Mothers and fathers play separately with their infant so that we can see if infant communication is different when they are playing with their mother or father. We are exploring whether infants vocalize when looking at their parents or toys and how looking at things can change how parents respond.
