First paragraph: Ernst von Glasersfeld’s contributions to the LANA Project (the Language Analogue Project) were very important to its seven years of success, 1971–1977, during which the effort was led by the senior author of this paper… Indeed, his contributions have helped perpetuate research into the language skills of apes and sea mammals to this day. Ernst was a member of the original team of 1970 that formulated the proposal to the National Institutes of Health for four years’ funding to develop a computer-monitored keyboard-situation appropriate to research on the language skills of which the great apes might be capable.

The linguistic-type skills of a young chimpanzee (Pan) acquired in a computer-controlled language-training situation are reviewed. Those skills include facile acquisition of vocabulary, object naming, color naming, appropriate use of “yes” and “no” in response to certain questions, and conversation. In conversations the subject has formulated novel sentences and without special training has asked that objects be named, whereupon requests were made that they be given to her. These findings are interpreted in terms of how enriched environments can serve to bring forth novel communication skills in the chimpanzee, which is otherwise alinguistic; how the challenge of the environment can serve to limit manifest intelligence; and how a cognitive, rather than the traditional stimulus-response, framework is required for understanding the communication skills and psychological processes of the chimpanzee.
