An important part of the Gorilla Foundation's mission is to apply our interspecies communication research — and Koko's motivational power — to educate the public about what gorillas are really like, how we can communicate with them, what we can learn from them, and how we can help them both in free-living and captive settings. We are working on new educational resources that leverage both technology and partnerships.  


Multimedia school and scientific presentations Incorporate the results of our research, and through video clips create a glimpse of what it's like to communicate with a gorilla. Koko challenges us to be better humans.  more
