Central auditory processing disorder (CAPD), as defined by the American Speech-Language-Hearing Association (ASHA), refers to difficulties in the perceptual processing of auditory information in the central nervous system and the neurobiological activity that underlies that processing and gives rise to electrophysiologic auditory potentials (ASHA,…

The auditory system helps regulate phonation. A speaker's perception of their own voice is likely to be of both emotional and functional significance. Although many investigations have observed deviating voice qualities in individuals who are prelingually deaf or profoundly hearing impaired, less is known regarding how older adults with acquired…

Purpose: The function of child-directed speech has been debated for decades. This study examined the perceptual and acoustic characteristics of child- and adult-directed Cantonese tones to test the hyperarticulation and prosodic hypotheses that have been proposed to account for the acoustic modifications in child-directed speech. Method: Sixty-two…

The purpose of this dissertation was to examine the development and importance of fingerspelling among young Deaf children of Deaf parents for communication, learning about language, and pre-literacy in their natural home environment. The rationale was to examine how Deaf parents use fingerspelling with their young Deaf children during…

When we look at a scene, we are conscious of only a small fraction of the available visual information at any given point in time. This raises profound questions regarding how information is selected, when awareness occurs, and the nature of the mechanisms underlying these processes. One tool that may be used to probe these issues is…

Purpose: Auditory perception of vowels in background noise is enhanced when combined with visually perceived speech features. The objective of this study was to investigate whether the influence of visual cues on vowel perception extends to incongruent vowels, in a manner similar to the McGurk effect observed with consonants. Method:…

Background: Research on retelling ability and cognition is limited in children with cerebral palsy (CP) and speech impairment. Aims: To explore the impact of expressive and receptive language, narrative discourse dimensions (Narrative Assessment Profile measures), auditory and visual memory, theory of mind (ToM) and non-verbal cognition on the…

This article explores the emergence of Emirati novice teachers' professional identity from a socio-cultural viewpoint where influences on identity are sourced internally through beliefs, attitudes, values and dispositions and externally through factors such as roles and responsibilities. Empirical data collected through individual and group…

Two explanations for resolving dyslexia were investigated, one assuming resolving underlying deficits and another assuming compensatory mechanisms based on cognitive strengths. Thirty-six Dutch gifted secondary-school students with either persistent (n = 18) or resolving (n = 18) dyslexia participated. Groups, matched on IQ, were assessed on…

The aim of the study was to conduct a systematic review in order to synthesize the evidence-based literature on mathematics education among students with visual impairment (VI). Studies were identified through searches of electronic databases (SCOPUS, PubMed, ERIC, and Web of Science). The authors included articles published between 1 January 2000…

This study investigates the perception and production of a specific type of metaphoric gesture that mimics melody in speech, also called "pitch gesture," in the learning of L2 suprasegmental features. In a between-subjects design, a total of 106 participants with no previous knowledge of Chinese were asked to observe (Experiment 1) and…

Introduction: The huge impact of technology in the last few decades, and the ample development of information and communication technologies (ICT) has established them as an essential characteristic of today's society. This vertiginous advance, and the quantity and diversity of changes in knowledge that are being generated, are inducing important…

The current study aims to assess the effectiveness of a program based on a multi-sensory strategy in developing of visual perception for primary school learners with learning disabilities. The study employed the quasi-experimental method on the experimental group of learners. A training program based on multi-sensory strategy was employed on a…

Recent research suggests that drawing activities can help students learn concepts in the science, technology, engineering, and mathematics (STEM) disciplines. In particular, drawing activities, which mimic the practices of STEM professionals, can help students engage with visual-spatial content. However, prior work has also shown that students…

In this dissertation, I investigated how cognitive resources as well as formal, and informal language experience impact language learning in two studies. In the first study (Chapter 2), I examined the learning of Spanish grammatical gender by Chinese international students who were studying abroad in the US. The goal of that study was to uncover…
