The mission of the MU Department of Communication Science and Disorders is to provide outstanding educational and research programs in the areas of language, speech, and hearing (including physiological, acoustic, perceptual, linguistic, cognitive, and social processes) and in the diagnosis and treatment of the spectrum of communication disorders. We have one of the oldest continually accredited programs in speech-language pathology in the nation and we offer the only PhD program in speech-language pathology in Missouri.

Individual variability in maternal infant-directed speech
(University of Missouri--Columbia, 2023)Infant-directed speech (IDS) is a universal, distinctive way in which adults speak to infants. IDS is characterized by a higher and more variable voice pitch, slower rate of speech, shorter utterances, more repetition, ... -
More than nouns, verbs, or adjectives: influence of word characteristics on vocabulary knowledge
(University of Missouri--Columbia, 2020)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Purpose- Although children generally learn nouns before verbs, form class does not fully explain differences in vocabulary knowledge. The ... -
Effects of menthol on swallowing function in a mouse model of presbyphagia
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The goal of this study was to characterize the progression of presbyphagia in our recently established mouse model and investigate the treatment effect ... -
Word learning from context : relations with language ability, socioeconomic status, and executive function
(University of Missouri--Columbia, 2017)During the school-age years, children learn most new word meanings from context rather than through deliberate vocabulary instruction. However, the actual process of word learning from context among schoolage children ... -
The effect of laryngeal nerve transection on swallowing function in a mouse model
(University of Missouri--Columbia, 2017)Dysphagia is a common postoperative complication of cervical and thoracic surgical procedures, presumably caused by iatrogenic laryngeal nerve injury. It is unknown which laryngeal nerve contributes most to dysphagia and ... -
A multiple subsystem approach to predicting speech intelligibility declines in older adults
(University of Missouri--Columbia, 2017)Introduction: Given the significant impact of progressive dysarthrias on individuals’ communication abilities and the increasing prevalence of progressive dysarthrias in the United States, it is becoming imperative to ... -
Characterization of dysphagia onset in a mouse model of amyotrophic lateral sclerosis (ALS
(University of Missouri--Columbia, 2017)The primary goal of this study was to characterize dysphagia onset and progression in the low copy number SOD1-G93A (LCN-SOD1) mouse model of ALS. A secondary goal was to determine the effect of serial radiation exposure ... -
Standardizing a freely-behaving canine videofluoroscopic swallow study protocol to investigate dysphagia in primary aging and neurological diseases
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The goal of this study was to establish a freely-behaving videofluoroscopic swallow study protocol (VFSS) for dogs that permits identification of ... -
Maternal behaviors following infant vocalization
(University of Missouri--Columbia, 2015)Studies of maternal responsiveness suggest responsive maternal utterances may encourage infant behaviors important to mastering speech and language. However, little is known about instances in which mothers are non-responsive. ... -
Noninvasive clinical tools to aid in early detection and monitoring of dysphagia in ALS : translating findings from mice to humans
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Previous work in our lab identified lingual dysfunction (i.e., slow lick rate) as the earliest clinical sign of dysphagia in SOD1-G93A transgenic mice, ... -
Videofluoroscopic characterization of dysphagia in the low copy number SOD1-G93A transgenic mouse model of ALS
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The goal of this study was to determine if the SOD1-G93A low copy number mouse model of ALS is a suitable model for studying dysphagia (i.e., swallowing ... -
Incidental word learning during reading : which skills do children use?
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Much of the growth in vocabulary during the school-age years occurs incidentally, as children encounter new words during silent reading. However, the ... -
Characterization of dysphagia in a canine model of late infantile neuronal ceroid lipofuscinosis
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Late Infantile Neuronal Ceroid Lipofuscinosis, also known as CLN2, is the most common form of Batten disease in children. Nearly all children with CLN2 ... -
