Yerkish is an artificial language developed for use by non-human primates. It employs a keyboard whose keys contain lexigrams, symbols corresponding to objects or ideas.[...]

Primates were taught to communicate by means of a lexigram board, a computerized array of keys labeled with lexigrams. Von Glasersfeld coined the term "lexigram" in 1971, created the first 120 of them, and designed the grammar that regulated their combination. This artificial language was called Yerkish in honor of Robert M. Yerkes, the founder of the laboratory within which the lexigrams were first used.

Moreover, Rosch argued that there is a "natural" level of categorization that we tend to use to communicate. This level is known as "basic-level categorization" and has been found to reflect a natural way humans categorize the objects in our world. This is important because we know that the processes of acquisition, storage and retrieval in the human brain are inextricably intertwined. Therefore, we can be fairly certain that basic-level categorization is a fundamental aspect of human cognition and communication.

Following the work of Rosch (1973) who first tried to connect these ideas into a psychological interpretation, we can conceive of these family resemblances as based on the fact that the human brain really possesses prototypes or exemplars in order to represent the meaning of a particular word, in relation to these. She found, through some extensive experiments with children, that there is in fact about 400 core concepts in western children, which are intensively used in growing up to interpret meaning.
