Current Research Interests:

The main objectives of my research program are to investigate how brain functions mediate language processing by addressing four critical questions: 1) Are brain functions distinctive for specific language tasks? 2) How does neural activity elicited by linguistic stimuli mature over the course of development? 3) Do brain functions for language processing differ for individuals with a variety of language experiences and proficiencies? 4) What are the neural indices of language processing in communicatively impaired individuals?

To address these questions, I use a multileveled approach involving both electrophysiological and behavioral measures. The experimental paradigms are designed to test different aspects of language processing (e.g., lexical integration, syntactic constraints, phonological awareness). Experimental outcomes are revealed in measures of event-related brain potentials (ERPs) and behavioral results, including response accuracy and reaction times. Our protocols also involve comprehensive assessments of speech and language abilities.

We discovered that neural indices characterize and distinguish various aspects of linguistic processing that develop in childhood and adolescence. Furthermore, we have demonstrated that electrophysiological and behavioral measures reveal differences in underlying processing of linguistic information in communicatively impaired populations, including children with language impairments and adults and children who stutter. We have also discovered how subtle, as well as clinically ascertained behavioral differences in language proficiency are reflected in neural patterns of activity elicited by linguistic stimuli. The converging evidence from our research program (across typical and disordered groups, across different points in development, and across different language tasks) indicates that neural activity for language processing is highly sensitive to developmental factors, experience, proficiency, and the type and complexity of linguistic information that is being processed. As our understanding about brain functions for language continues to evolve, our work will ultimately help establish how our differences as individuals, with our unique experiential and proficiency profiles are mediated by functioning of specific neural systems for language. Finally, our work will help to elucidate which neural functions characterize less efficient language processing systems in individuals who stutter and those with language impairments, and when these differences arise during development in these populations. Results such as these are critical for future development of improved treatment of these and other communication disorders.
