In this team task, the contestants had to direct their blindfolded teammates to a particular spot using only three words at a time, every 30 seconds. To accomplish the task, the “directors” need to put themselves in the shoes of their blindfolded teammates.
This task is a nice demonstration to show alongside a discussion of establishing common ground and referential communication.
The full task goes from 28:47 to 38:07, but ending at 32:18 is probably sufficient for a demo.
