Episodic-like memory for the "where" component of unique events was examined in an adult gorilla (Gorilla gorilla gorilla). The gorilla witnessed a unique event, performed by an experimenter (e.g. watching an experimenter blow bubbles) at one of three locations surrounding his enclosure. After a 4 to 17 minute retention interval, a tester presented the gorilla with photographs of the three locations, which were mounted on wooden cards, and asked the gorilla where the event had occurred. The gorilla communicated his choice by handing a card to the tester and was rewarded if correct. The gorilla was significantly above chance at identifying the event location. Results suggest that the gorilla was not responding on the basis of familiarity by choosing the most recently visited location, but choosing the location where the event occurred.
