People have a tendency to repeat the types of sentences they use during lan
guage production. Recent experimental work has shown that this phenomenon i
s at least partly due to 'syntactic priming', whereby the act of processing
an utterance with a particular form facilitates processing a subsequent ut
terance with the same or a related form. In this review, we first provide a
n overview of the evidence for syntactic priming. The review will then expl
ore the implications of this research for three different areas of language
theory: the possible functional significance of syntactic priming in coord
inating speakers during dialogue, the mechanisms underlying sentence produc
tion, and the nature of linguistic representation.
