Laboratories for Communication Sciences & Disorders
Students are encouraged to participate in our research projects.
The department of Communication Sciences and Disorders, housed within the Ruth S. Ammon College of Education and Health Sciences, plans to relocate all its various laboratories to Linen Hall in the coming year.
Neurophysiology in Speech Language Pathology (NSLP) Lab
Director: Reem Khamis-Dakwar, PhD
Currently in Hy Weinberg Center, Room 114
Research at the NSLP Lab focuses on examining the neural underpinnings of language learning in specific sociolinguistic situations, specific communication and language disorders, as well as during rehabilitation using event-related potentials (ERPs) recorded from 32 electrode arrays placed on the scalp combined with behavioral data.
Neurocognition of Communication Disorders (NCCD) Lab
Director: Melissa Randazzo, PhD
The NCCD Lab conducts experiments examining the neural underpinnings of multisensory integration in relation to linguistic and cognitive processing in healthy aging and aging-related disorders. We utilize a combination of behavioral and electrophysiological techniques to conduct clinically relevant investigations to inform diagnosis and treatment of communication disorders. Additionally, the NCCD Lab supports student research at the undergraduate, master’s and doctoral levels by facilitating the development of clinically relevant research questions and hands-on training with neuroimaging equipment.
The Voice and Quality of Life Laboratory (VQLL)
Director: Steven Cox, PhD
The VQLL seeks to investigate clinically based research questions focused on the human voice and how voice disorders can impact individuals’ physical, psychological, and social functioning. Particular emphasis is placed on individuals who undergo treatment for head and neck cancer. For example, individuals who have their voice box removed due to cancer often require an alternate method of speaking (e.g., ‘alaryngeal’ voice and speech). As a result, they can experience numerous changes in physical, psychological and social functioning. The VQLL focuses on the role of speech-language pathology and inter-professional intervention toward improving the quality of life for individuals with voice disorders, including laryngectomees.
The Language Observation and Analysis Laboratory
Director: Dana Battaglia, PhD
The Language Observation and Analysis Laboratory houses behavioral monitoring equipment, such as E-prime software, and SALT. Research at the LOA Lab focuses on examining the nature of word associations in typical and clinical populations. At present, the focus of the lab is to investigate word association in individuals with ASD, using behavioral methods.
Augmentative/Alternative Communication (AAC) Lab
Director: Cindy Arroyo, DA
The AAC Lab provides evaluations/consultations for individuals with severe communication impairments, as well as opportunities for teaching and research in the use of technology for individuals with severe communication impairments.
Speech Science Lab
Director: Laura L. Koening, PhD
The Speech Science Lab was originally developed by emeritus professor Dr. Lawrence Raphael. It includes specialized hardware and software that can be used to assess speech acoustics, aerodynamics (oral airflow), and articulatory contacts (electropalatography). Dr. Koenig has been working to add to and modernize this equipment. We have recently obtained newer equipment to measure air pressures during speech, a portable digital audio recorder that provides high-quality sound recording and can be used off-site, and a wireless microphone system—quite useful for recording young children, since the children can move freely while being recorded.
