Examining the factors that affect structural repetition in question answering.

We present two experiments that examine structural priming in the single-trial phone-call paradigm introduced by Levelt and Kelter (Cognitive psychology, 14 (1), 78-106, 1982). Experimenters called businesses and asked either What time do you close? or At what time do you close? Participants were more likely to produce a prepositional response (At 7 o'clock vs. 7 o'clock) following a prepositional question than following a non-prepositional question.
