Who Knows More and Noisy Classroom

Who: Children ages 3 to 5 years old.

Who knows more: We want to know how children reason about what others know based on the effects of their communication. Children will watch videos of “wubs” (puppets) trying to figure out how a toy works and communicate with each other. After the video we will ask which wub knows how the toy works!

Noisy classroom: Do children understand that noise can prevent someone from understanding speech? In this study, we show children short video clips of a teacher and her student who wants to learn about some cool new toys in the class. But because the classroom is noisy, it can be hard for the students to hear what the teacher is saying. We are curious if children infer that the student might not understand everything the teacher says. [Study Duration: 5 min]
