Department of Speech and Hearing Science

Research

The ability of humans to communicate using speech, language and hearing is one of the most important of all human behaviors. The faculty of the Department of Speech and Hearing Science at Arizona State University use state-of-the-art cognitive, behavioral and neuroscience techniques to study the components of human communication—speech, language and hearing—to advance our knowledge of this crucial behavior and to provide new ways to diagnosis and treat those with communication disorders and diseases. The research pursued in the many laboratories are organized around three main themes:

  • Auditory and Language Cognitive Neuroscience
    Auditory cognitive neuroscience is the study of the neural processing of sound from the cochlea to the cortex. The study of auditory cognitive neuroscience within the Department of Speech and Hearing Science at ASU includes research about normal and impaired speech-production mechanisms, normal and impaired auditory systems and prosthetic devices for hearing, especially the cochlear implant.
  • Developmental and Educational Sciences
    Developmental and early educational sciences research focuses on typically and atypically developing children in the age range of birth through eight years. Emphasis is placed on the acquisition and use of communication and language and how language develops in these maturing systems. Developmental and early educational sciences research is connected to the role communication and language plays in a child's education and everyday life, and the cognitive and educational challenges children face when disorders, disabilities or differences compromise language acquisition and use.
  • Habilitative/Rehabilitative Sciences
    Habilitative/rehabilitative sciences in speech, language and hearing investigates communication disorders and diseases in order to discover new techniques to assist those who are challenged in their ability to speak, hear, or use language. Research in the areas of habilitative/rehabilitative sciences involves a close cooperation between various research laboratories of the Department of Speech and Hearing Science and the state-of-the-art clinics in the department as well as several facilities in the greater Phoenix area and beyond.

Research on these themes and that involve the various expertise of the Department of Speech and Hearing Science faculty are carried out in the department laboratories, institutes and facilities, many of which are described in more detail below. Our academic faculty are very active researchers, and many are supported by grants from the National Intstitutes of Health or other extramural funding sources. As a department, and in collaboration with our colleagues across the country, we are responsible for nearly $25 million in current extramural funding.

The Department of Speech and Hearing Science also has several student research opportunities.
