In the last decade, graph theory has been widely employed in the study of natural phenomena. In this talk, I discuss the use of graph structure analysis to characterize discourse production among bilingual and clinical populations. I present evidence from college-aged learners of a second language, older adults with dementia and adults with post-stroke aphasia to suggest that measures of connectivity in spontaneous speech may be used to predict second language proficiency in bilinguals, but also symptom severity among clinical populations. This approach provides an alternative to verbal fluency and confrontation naming for assessing language abilities in clinical populations.

Prosem Lecture: Examining Effects of Elicitation Modality on Learning to Produce Novel Sound Sequences

Recent studies have consistently demonstrated that adult speakers can learn to be better at producing novel sound sequences, such as non-native onset clusters (e.g., GDEEMOO) in a practice-based motor learning paradigm. While each learner’s speech responses are typically elicited following both auditory and orthographic models in this paradigm, how this elicitation approach contributes to non-native cluster learning remains incompletely understood. Motived by the fact that speakers also face difficulty in perceiving the non-native clusters accurately, in this presentation, I will discuss an ongoing study that examined the extent to which learning to produce non-native clusters is impacted by the presence of auditory models in the production training task.

Prosem Lecture: Children Who are Deaf/Hard of Hearing Developing Two Spoken Languages: Igniting New Clinical Practices

62 Goodnight Hall

In this talk Dr. Benítez-Barrera will present recent research findings related to bilingual language development in children who are deaf and/or hard of hearing. He will use Spanish-English bilingual children as a model to provide best clinical practices for all clinicians working with families for whom English is not their primary language. He will also reflect on how cultural values as well as additional factors such as socioeconomic status and parental education might impact language development in this population. He will discuss how clinicians can embrace these values and differences to support successful outcomes. Attendees will walk away with a better understanding of bilingual spoken language development in children who are deaf and/or hard of hearing.

Hearing and Donuts (Brain and Bagels) Seminar

Sensorineural deafness has two underlying origins, environmental and genetic. In both cases, a major cause is death of the cochlear hair cells.  To understand the mechanisms of hair cell death, we have studied point mutations in the mechano-electrical (MET) channel protein, TMC1. These mutants surprisingly preserve MET channel function early in mouse neonatal development, but channel function is subsequently lost later in development, in the third to fourth postnatal week. This culminates in death of the hair cells and deafness. I shall describe two of the TMC1 mutants and possible experiments to document loss of MET channel function. I shall also discuss a possible link, involving reduced calcium influx through the MET channel leading to disorganization of hair bundle structure.

Prosem Lecture: Over-the-Counter Hearing Aids: Current Status and Future Challenges

62 Goodnight Hall
@ 12:00 pm - 1:00 pm

The Over-the-Counter (OTC) Hearing Aid Act went into effect in the fall of 2022, making hearing aids available without a prescription from an audiologist. What are OTC hearing aids? Who are they for? How can people with hearing loss successfully use OTC hearing aids? This talk will first review the motivation for, history, and current legal and regulatory status of OTC hearing aids. Then, the challenges, particularly service-delivery and self-fitting, for OTC hearing aids will be discussed. Particular attention will be paid to our recent work in developing hearing aid gain-frequency presets that maximize coverage for the potential OTC user population.
