This volume brings together contributions by prominent researchers in thefields of language processing and language acquisition on topics of common how people refer to objects in the world, how people comprehend such referentialexpressions, and how children acquire the ability to refer and to understandreference. The contributors first discuss issues related to children's acquisitionand processing of reference, then consider evidence of adults' processing ofreference from eye-tracking methods (the visual-world paradigm) and from corpora andreading experiments. They go on to discuss such topics as how children resolveambiguity, children's difficulty in understanding coreference, the use of eyemovements to physical objects to measure the accessibility of different referents, the uses of probabilistic and pragmatic information in language comprehension, antecedent accessibility and salience in reference, and neuropsychological data fromthe event-related potential (ERP) recording literature.
