This
study examines the event- related brain potential (ERP) of 25 Mexican
monolingual Spanish-speakers when reading Spanish sentences with single entity
anaphora or complex anaphora. Complex anaphora is an expression that refer to
propositions, states, facts or events while, a single entity anaphora is an
expression that refers back to a concrete object. Here we compare the cognitive
cost in processing a single entity anaphora (éstafeminine; La renuncia [resignation) from a complex
anaphora (estoneuter; La
renuncia fue aceptada [The resignation was accepted]).
