My primary research projects ask how the parser navigates and represents sentential structure in real-time upon encountering an ambiguous string in the context of certain other linguistic and extra-linguistic information.

For instance, prosodic boundaries may indicate syntactic constituent boundaries, but since they are produced with high variability (depending on many complex factors), it is not clear whether or not the parser will use such information in its initial representations. If the parser only takes prosodic boundaries into account when other information has already been processed, then unusual or inconsistent prosodic boundaries in structurally ambiguous sentences won’t change the parser’s behavior while it builds an initial representation of a sentence. However, if the parser uses prosodic information early on to determine syntactic constituents, then unusual or inconsistent prosodic boundaries could confuse or mislead the parser and create notable slow-downs associated with garden-path effects.

In coreference resolution between a pronoun and a name, there is often an assumption that gender is a formal feature of the [English] word, thus is processed with other lexical/grammatical features. Furthermore, there is an increase in recognition of nonbinary genders and nonbinary pronouns (‘neopronouns’). It is not clear how one’s exposure to nonbinary genders and neopronoun use will influence real-time, early long-distance dependency formation. On one hand, pronouns are a conservative closed class in English, so it may be difficult to influence ingrained processing behavior associated with coreference dependency formation. On the other hand, meaningful and consistent exposure to people with non-binary genders and people who use so-called neopronouns may be sufficient to influence the lexical category and the way in which the earliest stages syntactic representation are built. Here is my AMLaP2017 poster that supports this latter possibility.

As a spin-off of this topic, I am also examining the possibility of a multidimensional “gender space” in which gender identities and personal names might be mapped. The objective of this is to provide more accurate and inclusive tools to researchers looking to examine the effects of linguistic behavior as a function of gender identity (e.g., one’s own identity or the encoding of another individual’s identity).
