Referring expressions like proforms (“it”) and demonstratives (“that”) are
at the center of discourse relationships, yet very little is known about
how people resolve reference to events, as opposed to reference to people
and objects. Using adverbial referring expression that unambiguously refer
to events ("so" and "thus"), and a novel paradigm designed to capture event
referent complexity, we ask if the form of the referring expression has an
effect on the complexity of the event that comprehenders interpret as the
referent. We report a significant main effect of form: interpreted
referents of "thus" are more complex than those of "so."
