Laryngeal & Speech Dynamics Lab
The Laryngeal & Speech Dynamics Lab (LSD), located in Wethington 106, is a shared, multipurpose research facility designed to study the physiological and behavioral aspects of speech and voice production. The LSD research group couples basic and clinical research, allowing for an integrated approach to the study of normal and disordered voice production and human communication. The LSD Lab director is Richard Andreatta, Ph.D.
The LSD lab is flexibly designed to study sensorimotor aspects of vocal tract systems, but the equipment setup and stimulus protocols can be adapted with minimal effort to support conceptually similar research studies in both the hand and limb systems. This flexibility allows for expanded research and training opportunities for other areas with related interests in the sensorimotor dynamics of skilled human behavior (i.e., Athletic Training, Physical Therapy, Kinesiology, Occupational Therapy). The lab contains systems to support video imaging of the laryngeal system (flexible and rigid high-speed endoscopy - Pentax); voice, acoustic, and aerodynamic assessment (Computer Speech Lab/PAS/Nasalence - Pentax); chest wall assessment (Respitrace), surface electromyography; lip and jaw kinematics using custom-built strain gage technology; force assessment of the tongue, lips and jaw; cutaneous psychophysics; and trigemino-facial reflex assessment. The LSD lab is also equipped with various signal generation, acquisition, and processing hardware and software to support our experiments.
Social Communication and Cognition Laboratory
Social Communication and Cognition Laboratory (SCCA Lab) is a 300 square foot facility within the UK Communication Sciences and Disorders Clinic on the first floor of the C. T. Wethington Building. The laboratory houses standardized assessments for social communication and social cognition. Dr. Peter Meulenbroek is the Director of the SCCA Lab and uses this space to conduct research on how social communication and cognitive disabilities in persons with TBI affect their ability to participate in life-defining social activities such as work, family, and social engagement. Since opening the lab, Dr. Meulenbroek has conducted research on validating his assessment of workplace communication, the Voicemail Elicitation Task (VET) and developed the Feedback and Advice Spoken Task (FAST). These assessment instruments assess communication competence in key aspects of workplace discourse.
The Language and Cognitive Neuroscience Laboratory
The Language and Cognitive Neuroscience Laboratory lab is also located the UK Communication Sciences and Disorders Clinic in the C.T. Wethington building. Directed by Dr. Isabell Hubbard, the lab is focused on better understanding the role of cognition in language processing, especially in clinical populations. Through this research we hope to design brain-based therapies to treat individuals living with aphasia and/or cognitive decline or dementia. We employ neuroimaging (MRI), eye-tracking, and pupil dilation measurements to aid our observational and treatment studies. Further, our treatment studies are aimed at functional outcomes for communication. Lastly we investigate the utility and efficacy of non-invasive brain stimulation as an adjuvant to traditional speech-language therapy.
