Intermediary Object States Are Activated by Sentences Describing Completed Events

Processing state change verb phrases (e.g., fill the cookie jar) during language comprehension appears to require the activation of representations encoding both the initial (an empty jar) and resultant states (a filled jar) of event participants. Given that the transitions between these states can generally be inferred (on the basis of experiential semantic knowledge), these boundary states may be the only states of event participants that are activated during sentence processing or at event boundaries. However, simulation-based accounts of representation and linguistic analyses of state change predicates suggest that, in addition to initial and resultant object states, intermediary object states should also be activated during sentence comprehension. To compare these two alternatives, we investigated the activation of initial, intermediary, and end object states by sentences describing completed events (e.g., Jasmine filled/has filled the cookie jar). Our results suggest that perceptual features associated with objects at intermediary points in an event are indeed activated and maintained in memory through at least the end of the event description. These findings support an account in which representations of the entire event sequence-not just the boundaries-are activated during language processing.
