Observers experience complex patterns of visual motion in daily life due to their own movements through space, the movement of objects, and the geometry of surfaces in the visible world. Motion information shapes behavior and brain activity beginning in infancy. And yet most prior behavioral research has focused on how children process only one…

Purpose: The goal of this study was to examine the effects of cognitive and linguistic skills on masked speech recognition for children with normal hearing in three different masking conditions: (a) speech-shaped noise (SSN), (b) amplitude-modulated SSN (AMSSN), and (c) two-talker speech (TTS). We hypothesized that children with better working…

Purpose: Cochlear implants (CIs) transmit a degraded version of the acoustic input to the listener. This impacts the perception of harmonic pitch, resulting in deficits in the perception of voice features critical to speech prosody. Such deficits may relate to changes in how children with CIs (CCIs) learn to produce vocal emotions. The purpose of…

Purpose: This study aimed to identify predictors of response to treatment for residual speech sound disorder (RSSD) affecting English rhotics. Progress was tracked during an initial phase of traditional motor-based treatment and a longer phase of treatment incorporating ultrasound biofeedback. Based on previous literature, we focused on baseline…

Musical expertise and working memory (WM) have been isolated as being the most important predictors of phonetic aptitude -- meaning the ability to imitate unfamiliar speech material. Although the link between language functions and musical expertise has been subject to many investigations, specific languages and their individual link to musical…

Purpose: Speech acoustic characteristics of children with cerebral palsy (CP) were examined with a multiple speech subsystems approach; speech intelligibility was evaluated using a prediction model in which acoustic measures were selected to represent three speech subsystems. Method: Nine acoustic variables reflecting different subsystems, and…

Here we explore relations between auditory perception of amplitude envelope structure, prosodic sensitivity, and phonological awareness in a sample of 56 typically-developing children and children with developmental dyslexia. We examine whether rise time sensitivity is linked to prosodic sensitivity, and whether prosodic sensitivity is linked to…
