My research focuses on the kinds of mental representations adults create when comprehending language. My research has focused on the conceptual representation of plurals. For example, consider the sentence The cats slept on the rug. When a comprehender hears this sentence what conceptual representation is built for “cats”? The plural referent cats could be left underspecified and represented as a single, non-differentiated group or it could be fully specified and thus represented as a set of differentiated cats. This question is important because if plurals are left underspecified, this could have implications for future processing. For example, if later the individuals in the plural need to be accessed, comprehension may slow down in order to individuate the entities in the plural, if it had not been previously done. My work is informed by formal linguistics as well as cognitive psychology.
