Creativity is a fundamental human accomplishment from scientific advances to composing music. The left dorsolateral prefrontal cortex (DLPFC) and inferior frontal gyrus (IFG) are important metacontrol hubs in flexibility and persistence brain states, respectively. Those hubs are related to divergent thinking, insight problem-solving, and…

Background: To contribute to smart, inclusive, sustainable, and multisensory practices in science education, this paper presents research that studied the use of electronic sensors by children to address a sound pollution problem in their school. A didactic sequence was specifically designed and implemented to that purpose. Participants: The…

In the first year of life, infants' speech perception becomes attuned to the sounds of their native language. This process of early phonetic learning has traditionally been framed as phonetic category acquisition. However, recent studies have hypothesized that the attunement may instead reflect a perceptual space learning process that does not…

This sociophonetic study examines affricate variation through a continuous lens using diachronic data from Caracas Spanish. We investigate the relationship between frication and occlusion period duration in affricate segments across two steps. First, we present a phonetic characterization of the dependent variable and its variants. Second, we…

In this research note I want to address some misunderstandings about the construct of redeployment and suggest that we need to fit these behavioural data from Yang, Chen and Xiao (YCX) into a broader context. I will suggest that these authors' work is not just about the failure of three models to predict equivalence classification. Equivalence…

An introductory phonetics course provides foundational content for future clinical practice and may serve as a student's first experience within the field of Communication Sciences and Disorders. The Students as Partners framework (Cook-Sather et al., 2014) offers a model for valuing student assets and experiences in co-creating learning materials…

This dissertation explores clear speech which is defined as a specific speaking style people adopt when fluent communication could be compromised for various reasons. Although acoustic properties and their perceptual benefits of clear speech produced by monolingual speakers of English are well documented, there has only been a small body of past…

Problems in understanding speech in noisy environments are characteristic for age-related hearing loss. Since hearing aids do not mitigate these communication problems in every case, potential alternatives in a clinical rehabilitation plan need to be explored. This study investigates whether a computer-based speechreading training improves…

There is a significant amount of research literature on the importance of identifying and building on students' experiences and ideas for making sense of the natural world, especially when engaging in science practices. Simultaneously, approaches to creating justice-oriented science education promote the need to focus on the diverse sense-making…

Purpose: Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of…

Purpose: Verbal working memory is poorer for children with hearing loss than for peers with normal hearing (NH), even with cochlear implantation and early intervention. Poor verbal working memory can affect academic performance, especially in higher grades, making this deficit a significant problem. This study examined the stability of verbal…

Purpose: The contribution of tissue mechanical response to vocal fatigue is poorly understood. This study investigated the fatigue response of vocal fold tissues to large-amplitude vibration exposure at phonatory frequencies, using an ex vivo ovine model. Method: Twelve sheep vocal fold mucosal specimens were subjected to sinusoidal, simple-shear…

Purpose: This study investigated the criterion (analytical and clinical) and construct (divergent) validity of a novel, acoustic-based framework composed of five key components of motor control: Coordination, Consistency, Speed, Precision, and Rate. Method: Acoustic and kinematic analyses were performed on audio recordings from 22 subjects with…

Purpose: Speech understanding in noise and horizontal sound localization is poor in most cochlear implant (CI) users with a hearing aid (bimodal stimulation). This study investigated the effect of static and less-extreme adaptive frequency compression in hearing aids on spatial hearing. By means of frequency compression, we aimed to restore…

Speakers vary in their pronunciations of the sounds in their native language. Listeners use lexical knowledge to adjust their phonetic categories to speakers' idiosyncratic pronunciations. Lexical information can, however, be inconclusive or become available too late to guide this phonetic retuning. Sentence context is known to affect lexical…
