Lab Projects

ELLA: Early Language and Literacy Acquisition in Children with Hearing Loss

Funded by NIH, the purpose of the ELLA study is to (a) determine the developmental trajectories of oral language, phonological processing, and orthographic knowledge for children with hearing loss across the preschool years and (b) determine whether preschool oral language, phonological processing, and orthographic knowledge predict unique variance in literacy achievement in children with hearing loss at age 6.

MINI: The Relation of Minimal Hearing Loss and Literacy Impairments in School-Age Children

Funded by the UofSC Office of the Provost, the purpose of the MINI study is to (a) determine if the rate of failed hearing screenings differ across children with reading impairments and children with typical reading skills and (b) determine whether children who fail hearing screenings emerge as particular reading profiles, based on the Simple View of Reading. Learn More about MINI

(PH)IL2: Fatigue in Middle School Students with Hearing Loss: The Roles of Language Comprehension and Listening Effort

Funded by the UofSC Office of the VP for Research, the purpose the the (PH)ILstudy is to (a) compare fatigue across groups that vary by hearing and language comprehension status and (b) determine the impact of background noise and language difficulty on fatigue. Learn More about (PH)IL2

SALSA: Developing a School-Age Language Screening Assessment

The purpose of the SALSA study is to develop a screening tool that can be used by school personnel as a quick measure to determine if full language impairment assessment is needed for school-age children. Learn More about SALSA


Student Projects

Written Expression in School-Age Children with Cochlear Implants

The purpose of this study is to evaluate the story writing skills (spelling, syntax, story grammar) of school-age children with cochlear implants. Learn More

Print-Referencing Training for Parents of Children with Hearing Loss

Funded by Dr. Werfel’s AARC Award from ASHA, the purpose of this study is to develop and evaluate a DVD-training program that teaches parents of children with hearing loss to use specific book-reading strategies that increase their children’s print knowledge. Learn More

Oral Word Reading Errors of Children with Dyslexia who Fail a Hearing Screening 

The purpose of this study is to compare word reading errors of children with dyslexia who fail a hearing screening and those who pass a hearing screening. Learn More

 

Past Studies

A Comparison of Articulation Interventions

The purpose of this study is to evaluate the effect of therapy modality (flash cards versus tablet) on children’s gains in speech sound production accuracy during articulation therapy. Learn More

Contributions of Phonological Processing to Reading and Spelling in School-Age Children with Cochlear Implants

The purpose of this study was to examine the relative contribution of the component skills of phonological processing—phonological awareness, phonological memory, and phonological recoding—to reading and spelling achievement in school-age children with cochlear implants. Learn More

Contributions of Linguistic Knowledge to Spelling in Elementary School Children with Specific Language Impairment

The purpose of this study was to systematically explore the relation between linguistic knowledge and spelling proficiency, independent of visual memory, in elementary children with and without language impairment. Learn More

Visual Attention to Print During Storybook Reading of Preschoolers with Hearing Loss

The purpose of this study was to investigate visual attention to print during storybook reading in preschool children with hearing loss. Learn More

Print-Referencing Behaviors of Parents of Preschoolers with Hearing Loss

The purpose of this study was to compare print-referencing behaviors of parents of preschoolers with and without hearing loss. Learn More

Improving Initial Sound Segmentation Skills of Preschool Children with Severe to Profound Hearing Loss

The purpose of this study was to evaluate the functional relation between initial sound awareness instruction and increased initial sound segmentation skill in children with hearing loss. Learn More

Segmentation and Representation of Consonant Blends in Kindergarten Children’s Spellings

The purpose of this study was to describe the growth of children's segmentation and representation of consonant blends in the kindergarten year and to evaluate the extent to which linguistic features influence segmentation and representation of consonant blends. Specifically, the roles of word position (initial blends, final blends), class of blends, homorganicity, and nasality were considered. Learn More
