This study analyzes the relationship between phonemic proficiency and orthographic learning in first and second-grade students. It is established in the empirical literature that phonemic skills play a crucial role in word-level reading. What is not thoroughly understood is why some children learn and remember words more efficiently than others.…

The science of reading has captured the attention of educators, policy makers, and the public. Elfrieda H. Hiebert recounts some of what she's learned from her recent exploration of the topic. She has found that research evidence tends to fall into three categories: research that provides unequivocal conclusions, research that holds promise for…

An often overlooked but fundamental issue for any comprehensive model of visual-word recognition is the representation of diacritical vowels: Do diacritical and nondiacritical vowels share their abstract letter representations? Recent research suggests that the answer is "yes" in languages where diacritics indicate suprasegmental…

Visual word recognition is facilitated by the presence of "orthographic neighbors" that mismatch the target word by a single letter substitution. However, researchers typically do not consider "where" neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate…

This dissertation investigates intuitions about Spanish syllable structure and whether or not word segmentation strategies are affected by these syllabic intuitions. The study utilizes monolingual Spanish speakers, L1 Spanish speakers who are L2 learners of English and L1 English speakers who are L2 learners of Spanish. For Spanish syllabic…

In recent years, the number of English learners (ELs) in U.S. public schools has rapidly grown, with Hispanic children accounting for more than half of Texas public school students, including pre-kindergarten and early childhood education. ELs continue to demonstrate lower reading achievement in comparison to their native English-speaking peers.…

The What Works Clearinghouse™ is a federally funded source of scientific evidence for what works in education. The What Works Clearinghouse aims to disseminate findings from rigorous education research to the education community. One mechanism for accomplishing this aim is the production of practice guides. Panels of national content experts,…

Early literacy assessment has become commonplace in the preschool years, with phonological awareness constituting one component of emergent literacy targeted by such practices. This within-subjects experimental study examines the role of word familiarity on 93 dual language preschoolers' performance on phoneme-level awareness tasks in…

Background: Intelligibility measurement is influenced by the characteristics of a speaker, listener and contextual factors. This study addresses the clinical problem of measuring speech intelligibility in children with velopharyngeal insufficiency (VPI) in real-world conditions. Aims: The purpose of the study was to investigate the effects of…

Background noise challenges auditory recognition of speech and may reveal the underlying deficits in auditory word recognition skills. Previous studies have reported an association between children's auditory skills and various linguistic skills, including phonology, although in some languages only. However, language-specific features influence…

Purpose: Readers can draw on their knowledge of sound-to-letter mappings to form expectations about the spellings of known spoken words prior to seeing them in written sentences. The current study asked whether such orthographic expectancies are observed in the absence of contextual support at the point of reading. Method: Seventy-eight adults…

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…

The purpose of this study was to examine the effects of word boxes on the phoneme segmentation, word identification, and spelling performance of a sample of children with autism. Three children with autism were selected on the basis of similar performance on early literacy skills as measured by the Dynamic Indicators of Basic Early Literacy Skills…

Given the well-documented consonant primacy established in Roman script, this study examined the role of consonants and vowels in lexical decision of Korean "Hangul" among skilled Korean readers in order to identify whether the salient role of consonants over vowels would be script-universal or script-specific. Three experiments were…

The purpose of this study was to examine the role of phonological information on visual word recognition by using letter transposition effects. The Korean writing system gives a unique opportunity to investigate such phenomenon since the transposition of the beginning consonant (onset) and the end consonant (coda) of a certain syllable allows one…
