The time-course with which readers use event-specific world knowledge (thematic fit) to
resolve structural ambiguity was explored through experiments and implementation of constraint-
based and two-stage models. In a norming study, subjects completed fragments that ended in the
ambiguous region of a reduced relative clause (The crook arrested/by/the/detective). Completion
proportions up to and including the were influenced by thematic fit. The results were simulated
using a competition model in which independently quantified syntactic and semantic constraints
simultaneously influenced interpretation. Predictions were then generated for a self-paced reading
task using model parameter values established by the off-line simulations. The pattern of reading
times matched the predictions of the constraint-based version of the model but differed substan-
