Psychophysical Auditory Filter Estimates Reveal Sharper Cochlear Tuning In Musicians, Gavin Bidelman, Jonathan Schug, Skyler Jennings, Shaum Bhagat

Faculty Publications

Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter selectivity. This hypothesis was directly tested by measuring both forward- and simultaneous-masked psychophysical tuning curves. Sharper filter tuning (i.e., higher Q10) was observed in musicians compared to nonmusicians. Findings suggest musicians' pervasive listening benefits may be facilitated, in part, by superior spectral processing/decomposition as early as the auditory periphery.

Concordance Between The Chang And The International Society Of Pediatric Oncology (Siop) Ototoxicity Grading Scales In Patients Treated With Cisplatin For Medulloblastoma, Johnnie Bass, Jie Huang, Arzu Onar-Thomas, Kay Chang, Shaum Bhagat, Murali Chintagumpala, Ute Bartels, Sridharan Gururangan, Tim Hassall, John Heath, Geoffrey Mccowage, Richard Cohn, Michael Fisher, Giles Robinson, Alberto Broniscer, Amar Gajjar, James Gurney

BackgroundReporting ototoxicity is frequently complicated by use of various ototoxicity criteria. The International Society of Pediatric Oncology (SIOP) ototoxicity grading scale was recently proposed for standardized use in reporting hearing loss outcomes across institutions. The aim of this study was to evaluate the concordance between the Chang and SIOP ototoxicity grading scales. Differences between the two scales were identified and the implications these differences may have in the clinical setting were discussed.ProceduresAudiological evaluations were reviewed for 379 patients with newly diagnosed medulloblastoma (ages 3–21 years). Each patient was enrolled on one of two St. Jude clinical protocols that included craniospinal …

Effects Of Age And Syntactic Complexity On Speech Motor Performance, Christopher Dromey, Kelsey Boyce, Ron Channell

Faculty Publications

Purpose: This study investigated the effect of age on articulatory movement and stability in young, middle-aged, and older adults. It also examined the potential influence of linguistic complexity on speech motor control across utterances that differed in their length and grammatical complexity.
Method: There were 60 participants in three age groups: 20-30 years, 40-50 years, and 60-70 years, with equal numbers of men and women in each group. The speakers produced 10 repetitions of five different stimuli, each of which included the same bilabial-loaded phrase in different grammatical contexts, while their lip movements were recorded.
Results: Participants from the 60 …

Structured Narrative Retell Instruction For Young Children From Low Socioeconomic Backgrounds: A Preliminary Study Of Feasibility, Suzanne M. Adlof, Angela N. Mcleod, Brianne Leftwich

Faculty Publications

Successful acquisition of literacy depends on adequate development of decoding skills as well as broader, meaning-related knowledge and skills for text comprehension. Children from low socioeconomic status (SES) backgrounds are often challenged in both domains, relative to peers who are not economically disadvantaged. The efficacy of code-focused instructional programs for at-risk preliterate children is well supported, but less evidence is available regarding interventions to improve broader language and comprehension skills. This preliminary study tested the feasibility of a new intervention, "structured narrative retell instruction" (SNRI), and explored its potential to enhance meaning-related knowledge and skills, including vocabulary, listening comprehension, and …
