In this paper we propose six implicationally related cognitive statuse
s relevant for explicating the use of referring expressions in natural
language discourse. These statuses are the conventional meanings sign
alled by determiners and pronouns, and interaction of the statuses wit
h Grice's Maxim of Quantity accounts for the actual distribution and i
nterpretation of forms when necessary conditions for the use of more t
han one form are met. This proposal is supported by an empirical study
of the distribution of referring expressions in naturally occurring d
iscourse in five languages-English, Japanese, Mandarin Chinese, Russia
n, and Spanish.
