Symbolic communication between two chimpanzees (Pan troglodytes)
TLDR
Through use of learned symbols, two chimpanzees accurately specified 11 foods by name to one another when the food item's identity was known by only one and they could not do this when denied use of the symbols.Abstract:
Through use of learned symbols, two chimpanzees accurately specified 11 foods by name to one another when the food item's identity was known by only one. They could not do this when denied use of the symbols. The chimpanzees then spontaneously requested specific foods of one another by name. Requests resulted in cooperative and reciprocal symbolically mediated food exchange.read more

A developmental model for the evolution of language and intelligence in early hominids
TL;DR: It is proposed that the common ancestor of the great apes and man displayed rudimentary forms of late sensorimotor and early preoperational intelligence similar to that of one- to four-year-old children, which arose as adaptations for extractive foraging with tools, which requires a long postweaning apprenticeship.

Language Comprehension in Ape and Child
TL;DR: Comparisons of the language comprehension skills of a 2-year-old child and an 8 year-old bonobo who was raised in a language environment similar to that in which children are raised but specifically modified to be appropriate for an ape suggest that the potential for language comprehension preceded the appearance of speech by several million years at minimum.

Two-Way Communication with an Infant Chimpanzee
TL;DR: In this article, a two-way communication with an infant chimpanzee is discussed, and the authors consider the problem of choosing an appropriate medium for communication with a chimpanzee, considering why a medium based on vocalization cannot be appropriate.

Symbolization, language, and chimpanzees: a theoretical reevaluation based on initial language acquisition processes in four young Pan troglodytes.
TL;DR: The results indicate that it is ill advised to begin language training by introducing the names of objects or their attributes, and that the decontextualization of lexigram usage and the symbolic uses of the words used in training are ill advised.
