This paper investigates syntactic priming in written language production using a completion task. The authors report five experiments that explore how syntactic information is represented in the lemma stratum of lexical entries. They extend the model proposed by Roelofs (1992, 1993), arguing that combinatorial information is phrasal and shared between different lemmas. The study shows that syntactic priming occurs when the verb is repeated, and that the magnitude of priming is not affected by changes in tense, aspect, or number between the prime and target. The results suggest that syntactic priming is influenced by whether the verb is repeated between the prime and target, with stronger priming observed when the verb is repeated. The experiments also show that syntactic priming occurs regardless of whether the verb is the same or different between the prime and target, and that varying the form of a verb does not affect priming. The findings support the idea that syntactic priming is not dependent on exact repetition of structure between the prime and target, but rather on the activation of syntactic information at the lemma stratum. The results demonstrate that syntactic priming occurs in written production between sentences that do not share the same verb, and that it is unaffected by differences in tense, aspect, or number between the prime and target. The study provides evidence for the representation of syntactic information within the lemma stratum and supports the model of the lemma stratum proposed by Roelofs.This paper investigates syntactic priming in written language production using a completion task.
