Among existing accounts of passivisation difficulty, some argue it depends on the predicate semantics (i.e. passives are more difficult with subject-experiencer than agent-patient verbs). Inconsistent with the accounts that predict passive difficulty, Paolazzi et al. (2019) found that passives were read faster than actives at the verb and object by-phrase in a series of self-paced reading experiments, with no modulation of verb type. However, self-paced reading provides limited direct measurement of late revision/interpretive processing. We used modified stimuli from Paolazzi et al. (2019) to re-examine this issue in two eye-tracking while reading experiments. We found that in late measures, passives with subject-experiencer verbs had longer fixation durations than actives at the verb and two subsequent regions but no difference was observed across agent-patient verbs. Subject-experiencer verbs provide a state, but the passive structure requires an event. Thus, the required eventive interpretation is coerced with subject-experiencers (if possible) and induces difficulty.
