Activation of syntactic information during language production.

In order to produce utterances, people must draw upon syntactic information. This paper considers how evidence from syntactic priming experiments casts light upon the nature of syntactic information activation during language production. We examine three issues: the way in which syntactic information is initially activated, the circumstances under which activation may persist or dissipate, and the effects of residual activation of syntactic information on subsequent language production. Evidence from dialog experiments suggests that the information that is initially activated is the same in both production and comprehension. Evidence about the persistence of activation following initial activation is more complex. We suggest that persistence may be related to the potential relevance of the information for subsequent syntactic processing. We show that current evidence is inconclusive about how long syntactic information remains activated.
