Association Between Craniofacial Anomalies And Newborn Hearing Screening Fail Rate, Kaitlyn Sheapp, Ruth S. Marin, Larry Medwetsky

Journal of Early Hearing Detection and Intervention

Purpose: Increased knowledge of the prevalence of various craniofacial anomalies and their associated risks for hearing loss can help guide 1) development of evidence-based practice regarding detection and documentation of risk factors at birth and 2) health care professionals to make appropriate recommendations for follow-up testing and monitoring.

Method: Records were reviewed for 39,813 infants born at Adventist HealthCare Shady Grove Medical Center and White Oak Medical Center between January 1, 2014 and December 31, 2019 to determine the association between the presence of craniofacial anomalies and newborn hearing screening fail rates, as well as the prevalence of confirmed hearing …

A Case Study On Accessible Reading With Deaf Children, Jody H. Cripps, Samuel J. Supalla, Laura A. Blackburn

Communication Disorders & Special Education Faculty Publications

The concept of accessible reading for deaf students is new and worthy of exploration. In the face of the reading difficulties often experienced by deaf students, the lack of a specialized reading methodology that works for them must be addressed. Central to the paper is a research case study undertaken with two young deaf students, proficient in American Sign Language (ASL) and learning to read. The students participated in a tutorial with a tutor knowledgeable in a specialized reading methodology called ASL Gloss. The participating students demonstrated progress in reading skills over time. Two reading measures were adapted from English …

Counseling For Patients With Hyperacusis, Mary Maraist

Communication Sciences and Disorders: Student Scholarship & Creative Works

Hyperacusis is the phenomenon of experiencing moderately loud sounds as overly loud and/or intensely annoying. Hyperacusis can also cause fear or pain in response to sound. There is no one known cause of hyperacusis, and because of the variety of ways it presents itself, the approximate prevalence is difficult to determine. Despite the ambiguity of hyperacusis, the audiologist is an important part of diagnosing and educating clients with hyperacusis. During this project we aimed to discover the challenges individuals with hyperacusis face. These include anxiety, depression and avoidance behavior, and sometimes co-occurring tinnitus and hearing loss. Another aim was to …

Early Uneven Ear Input Induces Long-Lasting Differences In Left-Right Motor Function, Michelle W.

How asymmetries in motor behavior become established normally or atypically in mammals remains unclear. An established model for motor asymmetry that is conserved across mammals can be obtained by experimentally inducing asymmetric striatal dopamine activity. However, the factors that can cause motor asymmetries in the absence of experimental manipulations to the brain remain unknown. Here, we show that mice with inner ear dysfunction display a robust left or right rotational preference, and this motor preference reflects an atypical asymmetry in cortico-striatal neurotransmission. By unilaterally targeting striatal activity with an antagonist of extracellular signal-regulated kinase (ERK), a downstream integrator of striatal …

Cross-Modal Interaction Between Vision And Hearing: A Speed—Accuracy Analysis, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Cross-modal facilitation of response time (RT) is said to occur in a selective attention task when the introduction of an irrelevant sound increases the speed at which visual stimuli are detected and identified. To investigate the source of the facilitation in RT, we asked participants to rapidly identify the color of lights in the quiet and when accompanied by a pulse of noise. The resulting measures of accuracy and RT were used to derive speed-accuracy trade-off functions (SATFs) separately for the noise and the no-noise conditions. The two resulting SATFs have similar slopes and intercepts and, thus, can be treated …

Tracking The Time To Recovery After Induced Loudness Reduction (L), Yoav Arieh, Karen Kelly, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

In induced loudness reduction (ILR), a strong tone causes the loudness of a subsequently presented weak tone to decrease. The aim of the experiment was to determine the time required for loudness to return to its initial level after ILR. Twenty-four subjects were exposed to 5, 10, 20, or 40 brief bursts of 2500-Hz pure tones at 80-dB SPL (inducers) and then tested in a series of paired comparison trials. Subjects compared the loudness of a weak target (2500 Hz at 60-dB SPL) to the loudness of a comparison tone at 500 Hz previously judged to match the target. The …

Time Course Of Loudness Recalibration: Implications For Loudness Enhancement, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Loudness recalibration, the effect of a relatively loud 2500-Hz recalibrating tone on the loudness of a relatively soft 2500-Hz target tone, was measured as a function of the interstimulus interval (ISI) between them. The loudness of the target tone, assessed by a 500-Hz comparison tone, declined when the ISI equaled or exceeded about 200 ms and leveled off at an ISI of about 700 ms. Notably, the target tone’s loudness did not change significantly at very short ISIs (<150 ms). The latter result is incompatible with the literature reporting loudness enhancement in this time window but is compatible with the suggestion made by Scharf, Buus, and Nieder [J. Acoust. Soc. Am. 112, 807–810 (2002)] that early measurements of enhancement were contaminated by the influence of the recalibrating tone on the comparison …

Recalibrating The Auditory System: A Speed–Accuracy Analysis Of Intensity Perception, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Recalibration in loudness perception refers to an adaptation-like change in relative responsiveness to auditory signals of different sound frequencies. Listening to relatively weak tones at one frequency and stronger tones at another make the latter appear softer. The authors showed recalibration not only in magnitude estimates of loudness but also in simple response times (RTs) and choice RTs. RTs depend on the sound intensity and may serve as surrogates for loudness. Most important, the speeded classification paradigm also provided measures of errors. RTs and errors can serve jointly to distinguish changes in sensitivity from changes in response criterion. The changes …
