- Examining linguistic factors related to spelling and writing abilities of children
- Developing assessment and interventions for spoken and written language disorders
- Examining factors related to successful language development and literacy skills, specifically reading and writing, with individuals with motor speech impairments who may or may not use augmentative-alternative communication
- Investigating the relationship between production and perception on working memory and literacy skills for individuals with motor speech impairments
- Examining and developing technology to assist in language and literacy learning for individuals with motor speech impairments
Neurocognitive Linguistics Laboratory

- Examining the role of cognitive processes on semantic processing
- Communication and swallowing disorders arising secondary to traumatic brain injury, stroke, neurologic disease, and dementias in both children and adults
Dr. Mark Hedrick
- Perceptual abilities of listeners with hearing loss
- Speech perception by listeners with normal hearing and listeners with hearing loss
- Elucidation of frequency and temporal coding mechanisms
- Sound localization ability
- Spatial release from masking
- Aided and prosthetic binaural, bilateral, and spatial hearing
- Hearing loss prevention
Speech Perception and Production Laboratory
Dr. Deborah Von Hapsburg
- The effect of signal audibility on the emergence of early vocalization patterns in hearing impaired infants.
- The effects of increasing word familiarity on bilingual speaker’s speech perception in noise
- Speech perception in noise in [Korean/English] bilingual listeners
- The contribution of sensory feedback to speech production and speech motor learning;
- The effects of contextual and listener factors on speech production;

Stuttering and Speech Science Laboratory
Dr. Tim Saltuklaroglu
- Investigations into the neural mechanisms responsible for inducing fluent speech in people who stutter.
- Examining the role of mirror neuron systems in speech perception and simulated production tasks via electroencephalograpy (EEG).
- Investigations into clinical efficacy of altered auditory feedback and other treatments for stuttering.
- Listener reactions to stuttering:
- Changes in eye-gaze behaviors and physiological responses. How these reactions may in turn affect people who stutter and their communicative interactions.
- Anticipatory reactions to stuttering in people who stutter. Changes in physiological responses of anxiety in anticipation of stuttered versus fluent speech.
- The effects of stuttering on manual functions.
Voice and Speech Science Laboratory
Dr. Molly Erickson
