Purpose: Speech perception in noise (SPiN) varies widely in individuals with normal hearing, which may be attributed to factors that are not reflected in the audiogram, such as inhibition. However, inhibition is involved at both sensory and cognitive stages of auditory perception, and while inhibition at the cognitive level has been shown to be a…

Purpose: The purpose of this study was to investigate the relationship between speech recognition benefit derived from the addition of a hearing aid (HA) to the nonimplanted ear (i.e., bimodal benefit) and spectral modulation detection (SMD) performance in the nonimplanted ear in a large clinical sample. An additional purpose was to investigate…

We provide a meta-analytic review of all group-comparison studies that used reading-level match design, were conducted in highly consistent European orthographies, included children with dyslexia younger than 13 years of age as participants, and included measures of one or more of the potential causes of dyslexia. We identified 21 studies meeting…

Purpose: Normal-hearing (NH) children acquire plural morphemes at different rates, with the segmental allomorphs /-s, -z/ (e.g., cat-s) being acquired before the syllabic allomorph /-[schwa]z/ (e.g., bus-es). Children with hearing loss (HL) have been reported to show delays in the production of plural morphology, raising the possibility that this…

Individuals differ in their ability to perceive and learn unfamiliar speech sounds, but we lack a comprehensive theoretical account that predicts individual differences in this skill. Predominant theories largely attribute difficulties of non-native speech perception to the relationships between non-native speech sounds/contrasts and…

Due in part to its complex nature, there is still much to uncover in the investigation of the neural processes that contribute to synchronization between speakers and listeners during communication in the context of social cognition, specifically between native and nonnative English speakers and listeners. This study used a novel method of…

This article reports on the findings of a qualitative case study exploring the auditory skill "deficits" of a twice-exceptional male student who had multiple exceptionalities, including deficits in auditory processing skills, which contributed to learning issues and social connection difficulties in unique ways. Auditory skill deficits…

Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

Purpose: This study details the intended and unintended consequences of pitch shifting with the commercially available Eventide Eclipse. Method: Ten vocally healthy participants (M = 22.0 years; 6 cisgender females, 4 cisgender males) produced a sustained /?/, creating an input signal. This input signal was processed in near real time by the…

Purpose: This study explores the role of overt and covert contrasts in speech perception by children with speech sound disorder (SSD). Method: Three groups of preschool-aged children (typically developing speech and language [TD], SSD with /s/~/?/ contrast [SSD-contrast], and SSD with /s/~/?/ collapse [SSD-collapse]) completed an identification…

Purpose: Spectral modulation detection is an increasingly common assay of suprathreshold auditory perception and has been correlated with speech perception performance. Here, the potential effects of stimulus duration and stimulus presentation level on spectral modulation detection were investigated. Method: Spectral modulation detection…

Purpose: This study compared auditory-perceptual measures of presence/absence and severity of vocal tremor to acoustic markers of vocal tremor. The validity (both concurrent and diagnostic) of various acoustic markers of vocal tremor was also assessed. Method: Fifty-six midvowel sustained [a:] recordings were selected to yield a representative…

A discussion of audio tones in the physics classroom will include mention of their frequency. The frequency of a periodic signal is a well-defined quantity that can readily be measured. A concept related to frequency is that of pitch. Pitch is a perceived quantity that cannot be measured directly and is most important when listeners characterize…

Purpose: Unexpected and sustained manipulations of auditory feedback during speech production result in "reflexive" and "adaptive" responses, which can shed light on feedback and feedforward auditory-motor control processes, respectively. Persons with Parkinson's disease (PwPD) have shown aberrant reflexive and adaptive…

The purpose of this study was to examine the effects of timbral instructions on pitch and timbre production. High school (n = 28) and collegiate (n = 28) trumpeters played sustained tones at two octave levels (written C4 and C5) following three types of timbral instructions (dark-timbre, bright-timbre, or neutral instructions). Presentation orders…
