The goal of this dissertation was to find converging evidence from behavioral and neuroimaging analyses of the mechanisms of orthographic integration with general language processes. By examining orthography effects, covert influences of orthography on non-written tasks, in participants with aphasia, we attempt to elucidate the nature of…

Speech sound disorder (SSD) puts children at risk for word reading difficulties but does not guarantee them. Research on early literacy skills in children with SSD has primarily focused on phonological awareness due to speech sound deficits associated with SSD. Researchers have begun to examine multiple factors beyond phonological awareness that…

This single subject experimental design study used an adapted alternating treatment design to examine the effects of a synthetic phonics intervention and an analytic phonics intervention on oral reading accuracy, oral reading rate, and letter-sound correspondences among first grade students. Students who were reading at least two levels below…

In the "Sound Pattern of English," Chomsky and Halle (1968) posited that English orthography, despite the complexity in how it relates to phonology, is in fact more "optimal" in at least one aspect: how it relates to morphology. A root or stem tends to maintain a constant visual form across words built upon it even as its…

Difficulties in writing can emerge as early as preschool, and often coincide with developing difficulties in reading (Berninger et al., 1997; Graham & Santangelo, 2014; Graham et al., 2020), as reading and writing are fundamentally connected skills (e.g., Fitzgerald & Shanahan, 2000). Writing instruction in general has had positive effects…

Learning to read in English is difficult for adult English language learners due to their diverse background, their level of experience with literacy in their first language, and their reason and desire for wanting to learn to read in English. Teachers of adult language learners must consider the educational and language experiences of adults…

This study examined the effects of an intensive remedial program, Wilson Reading System (WRS), on 43 struggling readers from second to twelfth grade. The students, who attended a large southwestern urban school district, were all at least two grade levels below their peers in reading. Participants received 20 hours of WRS instruction over the…

The current study is on second language acquisition (SLA), and the focus is on the process of visual word recognition in English by Arab learners of English as a second language (ESL). Arab ESL learners have poor performance in their visual word recognition in English, which has been explicated in terms of their poor spelling knowledge of English…

Accurate and rapid word recognition requires highly-specified phonological, orthographic, and semantic word-specific representations. It has been established that children acquire these representations through phonological decoding in a process known as orthographic learning. Studies examining orthographic learning and its predictors have thus far…

The purpose of this study was to investigate the use of linguistic knowledge in spelling by analyzing spelling errors made by 220 students in the fourth, fifth, and seventh grades. A 25-word researcher-designed spelling test with considerations of word frequency, word familiarity, and word type (based on morphological complexity) was administered.…

Teaching a child to read is one of the greatest gifts we can give to that individual and to society as a whole, and yet many students exit school without the necessary literacy skills. For decades, research has demonstrated the importance of phonemic awareness in the development of the alphabetic principle, a prerequisite for competent reading,…

This study examined the relationships between concept of word development and other early literacy measures (rhyme awareness, beginning sound awareness, alphabet knowledge, letter sound knowledge, spelling, and word recognition in isolation) using data from the PALS-K. Supporting previous research by using a much larger data set than had been used…
