Description
In these sentences the first verb is ambiguous: (1) it is could be a finite past-tense verb, in which case it is the main verb of the sentence, or (2) it could be a passive participle, in which case it begins a reduced relative clause postmodifying of the subject, in which case the main verb of the sentence is still to come. The disambiguating region, which we label here as "disambiguator", rules out the first possibility. (In cases where the preceding context is strongly biasing toward the first interpretation, the disruption in human comprehension can be so high as to render the grammatical interpretation inaccessible, as many people find with the famous sentence "The horse raced past the barn fell".) If, in contrast, the postmodifying relative clause is unreduced, possibility (1) is ruled out from the start and disambiguator should be less surprising. Likewise, if the passive participle does not have the same form as a simple-past tense verb (such as "forgotten" vs. "forgot"), possibility (1) is ruled out from the start and the disambiguator should be less surprising.

((618,reduced_ambig/5,Disambiguator) - (617,unreduced_ambig/5,Disambiguator)) > ((620,reduced_unambig/5,Disambiguator) - (619,unreduced_unambig/5,Disambiguator)) We expect that the surprisal at the disambiguator in the reduced ambig minus the surprisal of the disambiguator in the unreduced ambig is less than its surprisal in the reduced un-ambig minus the unreduced un-ambig condition. This is because the disambiguator should be more surprising when the relative clause is reduced (not introduced by a “who was…” or “which was…”) and when the relative clause contains an ambiguous verb (like “brought” vs. “given”).
