Abstract
We investigate whether and in what conditions pronominal anaphora could be acquired by intelligent agents as a means to express recently mentioned entities. The use of pronouns is conditioned by the existence of a memory recording the object previously in focus. The approach follows an evolutionary paradigm of language acquisition. Experiments show that pronouns can be easily included in a vocabulary of a community of 10 agents dialoguing on a static scene and that, generally, they enhance the communication success.
