The psycholinguistic literature provides evidence for syntactic priming, ., the tendency to repeat structures. This paper describes a method for incorporating priming into an incremental probabilistic parser. Three models are compared, which involve priming of rules between sentences, within sentences, and within coordinate structures. These models simulate the reading time advantage for parallel structures found in human data, and also yield a small increase in overall parsing accuracy. | Integrating Syntactic Priming into an Incremental Probabilistic Parser with an Application to Psycholinguistic Modeling AmitDubey and Frank Keller and Patrick Sturt Human Communication Research Centre University of Edinburgh 2 Buccleuch Place Edinburgh EH8 9LW UK @ Abstract The psycholinguistic literature provides evidence for syntactic priming . the tendency to repeat structures.

Bock 1986 . Most work on syntactic priming has been concerned with sentence production however recent studies also demonstrate a preference for structural repetition in human parsing. This includes the so-called parallelism effect demonstrated by Frazier et al. 2000 speakers processes coordinated structures more quickly when the second conjunct repeats the syntactic structure of the first conjunct. Two alternative accounts of the parallelism effect have been proposed. Dubey et al. 2005 argue that the effect is simply an instance of a pervasive syntactic priming mechanism in human parsing. They provide evidence from a series of corpus studies which show that parallelism is not limited to co-ordination but occurs in a wide range of syntactic structures both within and between sentences as predicted if a general priming mechanism is assumed. They also show this effect is stronger in coordinate structures which could explain Frazier et al. s 2000 results. Frazier and Clifton 2001 .
