Fictive motion as cognitive simulation.

Sentences such as The road runs through the valley and The mountain range goes from Canada to Mexico include a motion verb but express no explicit motion or state change. It is argued that these sentences involve fictive motion, an implicit type of motion. But do people trying to understand these sentences mentally simulate motion? This question was addressed in four experiments. In each, participants read a story about travel--for instance, fast versus slow, short versus long distance, and easy versus difficult terrain--and then made a timed decision about a fictive motion sentence. Overall, latencies were shorter after they had read about fast travel, short distances, and easy terrains. Critically, the effect did not arise with nonfictive motion target sentences (e.g., The road is in the valley), as was demonstrated in three control studies. The results suggest that the processing of fictive motion includes mental simulation.
