Several observations of artificial language use are presented, suggest
ing an analogy in cognitive processing between artificial and natural
language use. This article stresses the value psycholinguistics has fo
r building a cognitive model of the artificial language user. An accou
nt for the presented observations of artificial language use is given
in terms of psycholinguistics, for example, common ground, the princip
le of optimal design, referring as a collaborative process, generaliza
tion, and incremental parallel production. Implications of the analogy
are also described and involve specific, testable predictions about u
ser behavior, as well as tentative design recommendations for future a
rtificial language interfaces that adapt to the cognitive processes un
derlying the user's artificial language use. Copyright (C) 1996 Elsevi
