Profound hearing loss can have serious and irreversible consequences for oral language development in children, affecting spoken and written language acquisition. Auditory-verbal therapy has been widely applied to children with hearing loss with promising results, mainly in developed countries where cochlear implants are available. An evaluation…

Purpose: The speech motor system uses feedforward and feedback control mechanisms that are both reliant on prediction errors. Here, we developed a state-space model to estimate the error sensitivity of the control systems. We examined (a) whether the model accounts for the error sensitivity of the control systems and (b) whether the two systems…

Lexical tone languages like Mandarin Chinese require listeners to discriminate among different pitch patterns. A syllable spoken with a rising pitch (e.g. "b[i-acute]" 'nose') carries a different meaning than the same syllable spoken with a falling pitch (e.g. "b[i with grave]" 'arm'). For native speakers (L1) of a non-tonal…

Distracted users can fail to correctly distinguish the differences between legitimate and malicious emails or search engine results. Mobile phone users can have a more challenging time identifying malicious content due to the smaller screen size and the limited security features in mobile phone applications. Thus, the main goal of this research…

In this article, we explore the implementation of a time-based intervention in a garden-based science, technology, engineering, art, and mathematics curriculum with a 3rd-grade science class that flipped the overdetermined functions of time and overdependence on predetermined learning outcomes to cultivate a disposition of sensitivity to the…

The purpose of this exploratory study was to examine speech characteristics in individuals with Parkinson's disease (PD) before and after participation in an 11-week choral singing intervention. Speech characteristics were analyzed using an acoustic measure of vowel space area (VSA) and a standardized speech intelligibility metric. Participants…

Purpose: Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and…

Purpose: We employed a time-gated word recognition task to investigate how children who are hard of hearing (CHH) and children with normal hearing (CNH) combine cognitive-linguistic abilities and acoustic--phonetic cues to recognize words in sentence-final position. Method: The current study included 40 CHH and 30 CNH in 1st or 3rd grade.…

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…

This study aimed to investigate how inquiry-based experiment-integrated science games affect the achievement and scientific process skills of 5th grade students. The topics of "Light and Sound" and "Electricity in Our Lives" were selected for the experiment. Two groups totaling 41 students participated. The research method…

Purpose: The purpose of the current study was to examine sensory and auditory memory limitations on intensity resolution in individuals with Parkinson's disease as compared to healthy older and younger adults. Method: Nineteen individuals with Parkinson's disease, 10 healthy age- and hearing-matched adults, and 10 healthy young adults were…

We developed a simple device to teach the concept of pH to visually impaired people through an experimental approach. An interface between a glass electrode and an open-source electronics platform based on easy-to-use hardware and software (Arduino Uno) was designed using an operational amplifier of ultralow input current. A headphone connected to…

In almost any given day, one will stumble upon sounds that are out of the ordinary, distinct enough to capture one's attention. Ordinary sounds in a home are represented by the white-noise-like background created by speaking, moving around, household appliances running, and so forth. The out of the ordinary is the sparkling sound of a knife blade…

The laptop ensemble is a platform that has recently been made possible by computer technology that enables individuals to perform music collaboratively. Research in this area has largely focused on the performance aspects, with very few studies focusing on the development of musical competency through participation in a laptop ensemble. This…

Background: The speech intelligibility of children with dysarthria and cerebral palsy has been observed to increase following therapy focusing on respiration and phonation. Aims: To determine if speech intelligibility change following intervention is associated with change in acoustic measures of voice. Methods & Procedures: We recorded 16…
