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…

The ability to recognize and name the sounds of alphabet letters is a crucial prerequisite for students as they embark on their journey to learn how to read. Regrettably, some children face significant challenges in this area. In this single-case multiple baseline study, we utilized mnemonic pictures to facilitate the memorization of the…

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…

The study aimed to investigate the effect of embodied learning on children's literacy skills and whether the activities were particularly beneficial for children at risk for reading difficulties. We conducted a randomized controlled trial during 4 weeks for grade 1 children (n = 52, age = 7.1). Children were randomly assigned to receive regular…

Background: Despite evidence that synthetic phonics teaching has increased reading attainments, a sizable minority of children struggle to acquire phonics skills and teachers lack clear principles for deciding what types of "additional" support are most beneficial. Synthetic phonics teaches children to read using a decoding strategy to…

Fluency with skills that operate below the word level (i.e., sublexical), such as phonemic awareness and alphabetic knowledge, may ease the acquisition of decoding skills (Ritchey & Speece, 2006). Measures of sublexical fluency such as phoneme segmentation fluency (PSF), letter naming fluency (LNF), and letter sound fluency (LSF) are widely…

We examined the response to a phonics through spelling intervention for children with developmental dyslexia in word and pseudoword reading efficiency and word spelling. Furthermore, we investigated to what extent the response to the intervention is robust across different cognitive profiles (phonological awareness, rapid automatized naming, and…

Kindergarten reading screening measures typically identify many students as at risk who later meet criteria on important outcome measures (i.e., false positives). To address this issue, we evaluated a gated screening process that included accelerated progress monitoring, followed by a simple goal/reward procedure (skill vs. performance assessment,…

Purpose: We report here, for the first time, on developmental surface dyslexia in Turkish, a very transparent orthography. Surface dyslexia is a deficit in the lexical route, which forces the reader to read words via the sublexical route, leading to regularization errors. Methods: To detect surface dyslexia, we used reading aloud of loanwords with…

This study examined distributional statistical learning of positional, phonetic, and semantic regularities of an artificial orthography in Chinese children aged 8-10 years: 29 with dyslexia, 29 age-matched controls, and 30 reading-level matched controls. Despite having positional regularity learning performance comparable to the controls, the…

The purpose of the present study was to examine the effects of a brief experimental intervention that integrated spelling practice into a systematic phonics approach to initial reading instruction for at-risk children. The effects of this intervention were studied by means of a randomized controlled trial design that compared the experimental…

This article details a large-scale tutor-to-teacher pipeline created in the midst of the COVID-19 pandemic. The program addressed two vital needs: 1) improving outcomes for striving readers in high-needs communities, and 2) improving teacher training in both evidence- and research-based instruction. Across school year (SY) 2020-2021 and 2021-2022,…

Central questions in the study of visual word recognition and developmental dyslexia are whether early lexical activation precedes and supports decoding (a dual-stage view) or not (dual-route view), and the locus of deficits in dysfluent reading. The dual-route view predicts early word frequency and length interaction, whereas the dual-stage view…

A brief experiment was designed to examine cognitive flexibility practice embedded in beginning phonics instruction for kindergarteners with limited early literacy learning. Previously tested phonics content included single- and high-frequency two-letter grapheme-phoneme correspondences (GPCs), introduced at a rate of 2-4 correspondences per week.…

Cross-cultural studies have suggested that reading deficits in developmental dyslexia (DD) can be moderated by orthographic depth. To further explore this issue and assess the moderating role of orthographic depth in the developmental cognitive trajectories of dyslexic and typical readers, we systematically reviewed 113 studies on DD that were…
