We study how children reason about people, objects, words, and numbers. We’re studying how children understand negation. Your child will be seated on your lap, and we will show them some short videos of puppets interacting with each other in various contexts. We will measure how long your child looks at these videos. This will help us to understand how children begin to comprehend the usage of the word ‘no’. 

The study itself lasts about 10 minutes, and the appointment should take about 30 minutes total, with added time for playing and filling out paperwork.  Your 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, 9:15am-5:00pm. For directions, see https://www.harvardlds.org/for-parents/labs-spaces-and-directions/william-james-hall-directions/.

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