Professor Aditi Lahiri has an ESRC project with Dr. Linda Wheeldon on the phonological encoding in language production, one of the issues being the relationship between the time it takes to begin an utterance and the nature of the initial consituent which the speaker plans to articulate. Research on language comprehension addresses the nature of the phonological representation in the mental lexicon. Behavioral reaction time experiments as well as EEG studies are conducted to address a variety of research issues.
