We study how children reason about people, objects, words, and numbers.  This study examines how young children learn and understand number. We will play some games with the child involving number in different ways. For example, there will be a bucket of toys and we will ask the child to give us a certain number of them. In another game, we will show the child some cards with objects on them and ask the child to quickly guess how many objects are on the card.  The parent can stay with the child the whole time.

The session takes about 20-30 minutes, but we schedule appointments for an hour to accommodate playing and filling out paperwork. The child gets to pick out a prize to take home (a stuffed animal, slinky, rubber duck etc.), and we will give the parent $5 as travel compensation.  If other children come along, a researcher will play with them during the study and they get to pick out prizes too.

We are located on Harvard’s campus and provide parking. Also, we can be reached easily from subway and bus routes.  We usually run this study Monday through Friday, 10:00am-5:00pm. For directions, see

We run studies by appointment only.  To schedule a time, please call, text, or email!
