How does a shared lexicon arise in population
of agents with differing lexicons,
and how can this shared lexicon be maintained
over multiple generations? In order
to get some insight into these questions
we present an ALife model in
which the lexicon dynamics of populations
that possess and lack metacommunicative
interaction (MCI) capabilities are
compared. <br>We ran a series of experiments
on multi-generational populations
whose initial state involved agents possessing
distinct lexicons. These experiments
reveal some clear differences in the
lexicon dynamics of populations that acquire
words solely by introspection contrasted
with populations that learn using
MCI or using a mixed strategy of introspection
and MCI. <br>The lexicon diverges
at a faster rate for an introspective population,
eventually collapsing to one single
form which is associated with all meanings.
This contrasts sharply with MCI capable
populations in which a lexicon is
maintained, where every meaning is associated
with a unique word. We also investigated
the effect of increasing the meaning
space and showed that it speeds up the
lexicon divergence for all populations irrespective
of their acquisition method.
