There is some interesting material on Koko in "The Other Side 
of Silence" by Arden Neisser.
 
It's basically about Deafness, but one fluent signer worked 
for a time with Koko and was disgusted by the slackness of the 
experimenters: They interpreted everything Koko did as 
meaningful, till she burst out, "If Koko broke the window and 
ran away, would you say he was making the sign for 'escape'?"
 
The book makes the point that the moment primates do anything 
with signs, people are very ready to say "They're using 
language!", yet Deaf people had to struggle for decades to have 
Sign Language recognised as valid human language.
