I have not read about the SoCal project. Maybe Koko? http://www.slate.com/articles/health_and_science/science/2014/08/koko_kanzi_and_ape_language_research_criticism_of_working_conditions_and.html
Not Koko, because Koko was a gorilla.
The chimp I used to see must have been one of the unnamed ones that is described here:
“Dedicated researchers brought apes like Koko into their homes or turned their labs into home-like environments where people and apes could play together and try, often awkwardly, to understand each other.”
