Syntactic priming in comprehension: evidence from event-related potentials

Area of Science:

• Psycholinguistics
• Cognitive Neuroscience
• Computational Linguistics

Background:

• Syntactic priming facilitates processing when sentences share grammatical structures.
• Priming effects are more robust in language production than comprehension.
• Previous comprehension studies often required verb repetition for priming.

Purpose of the Study:

• To investigate syntactic priming in language comprehension using event-related potentials (ERPs).
• To determine if syntactic priming occurs independently of lexical (verb) repetition.
• To examine the neural correlates of syntactic priming in comprehension.

Main Methods:

• An event-related potential (ERP) experiment was conducted.
• Participants read target sentences with reduced-relative clauses.
• Sentences were preceded by primes with either reduced-relative or main-clause structures, sharing the same verb.

Main Results:

• Reduced-relative clause primes elicited greater positivity compared to main-clause primes.
• Target sentences following main-clause primes showed greater positivity than those following reduced-relative primes.
• Syntactic priming effects were distinct from lexical repetition effects.

Conclusions:

• Syntactic priming can occur in language comprehension without explicit verb repetition.
• The findings suggest that syntactic structure itself can mediate priming effects.
• ERP measures reveal neural evidence for syntactic priming in comprehension.
