The purpose of this qualitative study was to examine the perceptions of principals' leadership styles and how they influenced teachers' job satisfaction in five Catholic high schools in the Bono and Bono East Regions of Ghana. The researcher employed a basic interpretive methodology to research these subjective domains. One-on-one interviews were…

Background: Phonetic transcription of disordered speech samples is especially crucial for the assessment and treatment of functional or organic speech-sound disorders. Previous studies show that students who struggle with the identification and segmentation of speech sounds are more likely to encounter difficulties with clinical phonetic…

This study investigated cross-cultural similarities and variations in children's developing understanding of mixed emotions. Four- to 9-year-old US (n = 56) and Chinese (n = 98) children listened to stories in which the protagonist encountered a situation combining positive and negative components. Children were asked whether the story protagonist…

This dissertation explores the relationship between quantitative phonetic measurements and listener identification of accents of English, focusing on phonetic distance and its perceptual correlates across various English accent varieties. The Levenshtein distance (LD) measure, which quantifies string similarity by calculating the minimum cost of…

In this mixed-methods convergent parallel database design study on the roles of the model professional learning communities (PLC), I explored the teacher's perceptions of the PLC process on teacher enhanced instruction and elementary student academic outcomes through interviews. I also examined archrival Texas Academic Performance Reports (TAPR)…

Background: Visual attention span (VAS) refers to the number of visual elements processed simultaneously in a multielement array. Yet, there are mixed findings regarding VAS deficit in developmental dyslexia (DD) across different tasks, stimuli, languages, control groups, and ages. Aim: The present meta-analysis aimed to investigate VAS deficit in…

This qualitative, phenomenological study examined undergraduate peer mentors' perceptions of the mentoring roles and their perceived student learning through their mentoring experiences. The participants' experiences were connected to the sociocultural theory of learning and self-determination theory. The study revealed four themes from peer…

Purpose: The aim of this study was to develop and validate a large Korean sentence set with varying degrees of semantic predictability that can be used for testing speech recognition and lexical processing. Method: Sentences differing in the degree of final-word predictability (predictable, neutral, and anomalous) were created with words selected…

Negative emotions such as mathematics anxiety (MA) may lead to the avoidance of mathematics, which can have dire consequences for future career-related decisions. This paper compared Grade 10 learners' levels of trait-MA with perceived MA according to the type of school and gender. Both quantitative and qualitative data through a survey conducted…

We present a neural network model of referent identification in a visual world task. Inputs are visual representations of item pairs unfolding with sequences of phonemes identifying the target item. The model is trained to output the semantic representation of the target and to suppress the distractor. The training set uses a 200-word lexicon…

Perception is not an independent, in-the-moment event. Instead, perceiving involves integrating prior expectations with current observations. How does this ability develop from infancy through adulthood? We examined how prior visual experience shapes visual perception in infants, children, and adults. Using an identical task across age groups, we…

To reveal the formation process of speech processing with early hearing experiences, we tracked the development of functional connectivity in the auditory and language-related cortical areas of 84 (36 female) congenitally deafened toddlers using repeated functional near-infrared spectroscopy for up to 36 months post cochlear implantation (CI).…

Previous research has variably indicated the role of working memory in error detection by which working memory played a role in rhythmic error detection but not melodic error detection. Here, we devised a longer melodic error detection task for college musicians in an auditory, rather than visual, condition using classical excerpts, which we…

Purpose: Stuttering is a neurodevelopmental disorder that disrupts the timing and rhythmic flow of speech production. There is growing evidence indicating that abnormal interactions between the auditory and motor cortices contribute to the development of stuttering. The present study investigated speech auditory-motor synchronization in stuttering…

For more than two decades, Norway has been one of the leading actors in engaging international volunteers to sport for development and peace (SDP) organisations in the Global South. SDP is a priority area of Norwegian sports politics, mainly projected through the Norwegian Olympic and Paralympic Committee and Confederation of Sports (NIF) where…
