Mayfest is a workshop that brings together researchers from a variety of disciplines and perspectives to discuss fundamental issues in linguistics. Over the course of two days, participants engage in talks and discussion sessions to stimulate new insights and collaboration. This year, we will be discussing the use of prediction in language and its neural instantiation. Researchers studying language perception, production, and development have been invited to speak about the representational properties, temporal dynamics, and neural underpinnings of expectations in language.
