Movie S3: Punishment Task. E1 places a large tray of food on a table in front of the chimpanzees; E2 sits across from the chimpanzee at a collapsible wing of the table held up by a removable leg. E1 previously threaded a rope attached to this leg into the chimpanzee’s room. After 5s, E2 steals the tray of food from the chimpanzee and pretends to eat the food. Here, the chimpanzee collapses the table by using the rope to pull out the removable leg from underneath the table wing.
