Video S4: Multiple Locations - Chimpanzee

Video S4: Multiple Locations (Study 2) – Chimpanzee. The experimenter (E) initially hid four test pieces of food in the enclosure while the chimpanzee observed; four control pieces had been previously hidden while the ape was out of sight. The video shows the start of the search phase after a 10-minute delay following the baiting demonstration. This chimpanzee observed the baiting from an adjacent tunnel and is released by a caretaker after E signals the 10-minute delay has concluded. This subject rapidly approaches two test locations (a grass patch and a water fountain). Test and control locations were counterbalanced across subjects tested in the same enclosure. This clip showed the first 30s of the search phase; the entire search phase lasted 10 min.
