Since the early 20th century, a number of curious (and sometimes ethically dubious) psychological studies have tried to figure out if we can communicate with great apes using language. In the 1970s, the answer was reported to be an unequivocal “yes” after Koko, a female western lowland gorilla, learned to sign at her handler, a graduate student at Stanford University, using a modified version of American Sign Language.
But more recent critiques of the Koko studies (and others) dispute the idea that great apes have had truly meaningful two-way language communication with humans. This video from NPR’s Skunk Bear offers a brief survey of the history of ape-human communication research, suggesting that “Can we talk with them?” might be the wrong question to ask.
