Purpose: Smith-Magenis syndrome (SMS), a rare, genetically linked complex developmental disorder caused by a deletion or mutation within chromosome 17p11.2, is associated with delays in speech-language development, otopathology, and hearing loss, yet previous studies lack comprehensive descriptions of hearing and communication profiles. Here,…

Numbers and letters are culturally created symbols that acquire meaning through extensive training, significantly influencing brain function. The distinct hemispheric specialization of cortical regions for these categories has been hypothesized to relate to the co-activated brain networks: the left language regions for letters, and the right…

Research literature about visually impaired students' approach to mathematics is still very scarce, especially in the case of algebra, even though mathematical content is becoming increasingly accessible thanks to assistive technologies. This paper presents a case study aimed at describing a blind subject's process of algebraic symbol manipulation…

Purpose: Many studies using machine learning (ML) in speech, language, and hearing sciences rely upon cross-validations with single data splitting. This study's first purpose is to provide quantitative evidence that would incentivize researchers to instead use the more robust data splitting method of nested k-fold cross-validation. The second…

Localizing sounds in noisy environments can be challenging. Here, we reproduce real-life soundscapes to investigate the effects of environmental noise on sound localization experience. We evaluated participants' performance and metacognitive assessments, including measures of sound localization effort and confidence, while also tracking their…

Children can only develop spoken language through consistent exposure to the acoustic cues that comprise speech and language. Until recently, hearing levels from the clinical audiogram were the primary measure used to define typical hearing and the presence or degree of a child's hearing loss. While the clinical audiogram remains an important…

Posthumanism points towards a relational understanding of embodied processes of becoming musical in and with the world which readily combine with existing aspects of early years music practice. In this article I describe the potential of this resonant encounter to develop alternative approaches to listening, opening further possibilities for both…

Purpose: The effect of onset asynchrony on dichotic vowel segregation and identification in normal-hearing (NH) and hearing-impaired (HI) listeners was examined. We hypothesized that fusion would decrease and identification performance would improve with increasing onset asynchrony. Additionally, we hypothesized that HI listeners would gain more…

The sense of hearing is very important in our need and ability to communicate with others, and for our safety. An audiologist describes features of the role of an audiologist and outlines training routes. Understanding how the ear works is the starting point, followed by basic details of some causes of hearing problems and management options for…

Background: Pragmatic language use in general and the use of evaluation devices (EDs) are very important components in everyday communication and expressing thoughts and feelings in narrative production. However, very little is known about the use of evaluative devices in the narratives of Arabic-speaking adolescents, especially those who are deaf…

Martha's Vineyard Sign Language (MVSL) is an extinct village sign language hypothesized to be a sister of British Sign Language (BSL) and a significant contributor to early American Sign Language (ASL) (Groce 1985). After the last deaf MVSL signer died, signs were elicited from five hearing signers. This study analyzes that data through a series…

Purpose: Acoustic and perceptual quantification of vocal strain has been a vexing problem for years. To increase measurement rigor, a suitable single-variable matching stimulus for strain was developed and validated, based on the matching stimulus used previously for breathy and rough voice qualities. Method: A set of 21 comparison stimuli for a…

Purpose: Amplitude modulations (AMs) are important for speech intelligibility, and deficits in speech intelligibility are a leading source of impairment in childhood listening difficulties (LiD). The present study aimed to explore the relationships between AM perception and speech-in-noise (SiN) comprehension in children and to determine whether…

Purpose: This study examined the impact of traumatic brain injury (TBI) on self-perceived hearing and suprathreshold binaural processing in young and middle-age adults. Method: Ninety-three adults with normal hearing (thresholds [less than or equal to] 25 dB HL, 250-4000 Hz) participated in one of four groups: 38 young adults, 23 young adults with…

Purpose: The long latency auditory evoked responses (LLAERs), originating in the auditory cortex, are often considered a biomarker for maturity in the central auditory system and may therefore be useful in the evaluation of children with central auditory processing disorder (CAPD). However, the characteristics of the LLAERs elicited in this…
