The P600 is an event-related brain potential (ERP) typically associated with the processing of grammatical anomalies or incongruities. A similar response has also been observed in fully acceptable long-distance "wh"-dependencies. Such findings raise the question of whether these ERP responses reflect common underlying processes, and what…

This article presents three studies that investigate when syntactic constraints become available during the processing of long-distance backwards pronominal dependencies ("backwards anaphora" or "cataphora"). Earlier work demonstrated that in such structures the parser initiates an active search for an antecedent for a pronoun, leading to gender…
