Book excerpt: Individual Differences in Anaphora Resolution: Language and cognitive effects explores anaphora resolution from different perspectives, and investigates various aspects of the phenomenon, as contributions include research protocols that combine old and new experimental methodologies as well as theoretical and empirical approaches. A central theme across volume contributions are the multiple linguistic and extralinguistic factors that constrain anaphora resolution, its processing and acquisition by a variety of populations (children and adults, monolinguals, bilinguals and second language learners) as well as the mechanisms underlying anaphora resolution. Anaphora resolution constitutes an ideal environment to test the interaction between domain-general cognitive systems and domain-specific linguistic sub-routines, since variability in referential preferences is not related to binding constraints (an integral part of syntax per se) but is closely tied to processing (functional constraints) modulated by the integration of discourse-filtered information.
