About

Dr. Emily Morgan has accepted an offer to join the linguistics department at UC Davis, staring in Summer 2018. She is currently on leave, finishing a postdoctoral research project in the Department of Psychology at Tufts University, working with Gina Kuperberg and Aniruddh Patel.

Research Focus

To know a language is to use one’s past linguistic experience to form expectations about future linguistic experience. This process is mediated by both speakers’ stored representations of their previous experience, and the online procedures used to process new stimuli in light of those representations. My research thus asks what the form of these representations is, and how the language processing system integrates these stored representations with incoming stimuli to form online expectations during language comprehension. For example, when one encounters a highly frequent phrase such as “bread and butter”, is this phrase represented and processed holistically as a single unit, or compositionally as a conjunction of nouns? Is the form of this representation influenced by the frequency of the expression (compared to a less frequent expression like “facts and techniques”) or its frozenness in a given order (compared to a more flexible expression like “boys and girls”/”girls and boys”)? To answer these questions, I combine experimental psycho- and neurolinguistic methods, such as eye-tracking and ERPs, with probabilistic computational modeling.

I also ask comparable questions in the domain of music: how is our previous musical experience represented and processed to form expectations for future experience? For example, to what extent does processing of melodies rely upon language-like hierarchical structure versus surface statistics (e.g. note to note transition probabilities)?
