In language comprehension, humans show a bias towards prototypical agents that is visible in, e.g., reduced N400 amplitudes elicited by full-NP arguments of a verb and anaphoric pronouns referring back to an agent. As most studies have manipulated agentivity via animacy, little is known about the impact of agentive semantic-role features provided by verbs (e.g. volition) and manner adverbs (e.g. intentionality). We investigate how volition and intentionality modulate readers’ agent bias during pronoun resolution, as reflected in N400 modulations. We find that volition is a stronger cue than intentionality, which only exerts its full influence in the absence of volition.
