Course Descriptions

The following undergraduate courses provide a foundation in communication sciences and disorders and may be required for those students that do not have an undergraduate degree in Communication Disorders.

COSI 211 - Phonetics and Phonology (3)
Theoretical and applied study of the speech sounds of language. The use of the international phonetic alphabet as a tool for characterizing normal and deviant sound patterns. The linguistic structure and function of speech sound systems of both the adult and developing child.

COSI 313 - Language Development (3)
Language acquisition theory and stages of development of syntax, semantics, pragmatics, and phonology in children. Contributions of biological, social, cognitive and environmental factors to process of language development. Information on language variation in multicultural populations. Open to majors and non-majors. Recommended prerequisites: Child Psychology

COSI 321 - Speech and Hearing Science (3)
Acoustics and the processes of speech/motor control. Human perception of speech sounds, motor control, methodological procedures, instrumentation and research findings. Prerequisite: COSI 325

COSI 325 - Anatomy and Physiology of Speech and Hearing Mechanisms (3)
The anatomy and physiology of normal speech production and of the hearing mechanism.

COSI 345 - Communication and Aging (3)
The normal and abnormal psychobiological changes that occur during aging and their effects on communication are addressed, as are communicative interaction styles, disordered communication, and rehabilitation practices.

COSI 352 - Introduction to Clinical Practice (3)
Clinical assessment and teaching procedures as well as the role of research/theory in clinical practice. Procedures to observe, measure, analyze communication skills. Practical application through case studies. Students complete 25 hours of observation of speech/language assessment and intervention. Prerequisite: COSI 211 and COSI 313, or consent of department.

COSI 357 - Acquired Neurogenic Communication Disorders (3)
This course is designed to provide knowledge about the theoretical foundations, etiologies, and characterizations of acquired language-based and cognitive-communication disorders in adults. The organization of the course is designed so that we will discuss communication disorders typically associated with left hemisphere lesions (e.g., aphasia), right hemisphere lesions (e.g., RHD), frontal lobe lesions (e.g., traumatic brain injury) and mesial temporal lesions (e.g. dementia). This course is intended to provide students with a framework for considering communication disorders of diverse medical etiologies rather than specific impairment types. The course is meant to provide information that can be used as a foundation for a clinically applied course in acquired language disorders. The course will focus on critical thinking, professional presentation (both oral and written), and critical consumption of research.

COSI 370 - Introduction to Audiology (3)
Disorders of hearing, assessment of hearing; including behavioral and objective measures; intervention strategies; and identification programs. Prerequisite: COSI 325 and COSI 321 or COSI 421

COSI 421 - Speech and Hearing Science (3)
(See COSI 321)

COSI 444 - Evidence-Based Practice in Communication Disorders (4)
Evidence-based practice is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual clients. Having its origins in the fields of medicine and clinical epidemiology, EBP is now a growing part of speech and language sciences. The goal of COSI 444 is to instill in you a career-long desire to seek out high-quality relevant evidence pertinent to the clinical questions that affect your practice.  To do this, you must first know how to find the evidence and evaluate the quality of evidence available. This course is intended to demystify the research process so that you can become critical consumers of the research literature in our field.

COSI 445 - Communication and Aging (3)
