Purpose: Phonological awareness (PA), the awareness of sounds in spoken words, is strongly linked to reading outcomes. However, there is an ongoing debate regarding the effectiveness of PA instruction without including print (i.e. PA without exposure to words or letters). Specifically, is PA-only instruction just as effective in improving reading…

Studies have suggested that multiple features influence letter knowledge across different orthographies. Arabic offers a unique opportunity to investigate the relations of letter properties on letter knowledge, but research on Arabic letter knowledge is scarce. This study was designed to investigate (a) letter frequency, (b) letter sequence, (c)…

Two methods of decoding instruction were compared. Participants were kindergartners who knew letter sounds but could not decode nonwords, M = 5.6 years. The segmented phonation treatment taught students to convert graphemes to phonemes by breaking the speech stream ("sss -- aaa -- nnn") before blending. The connected phonation treatment…

Learning the relationships between letters and sounds is a key component of early literacy development and a central aim during the first year of school. Introducing one new letter a week is the most common approach in many countries, but little is known about how the pace of letter instruction contributes to the development of early literacy…

To expand our understanding of script-general and script-specific principles in the learning of letter names, we examined how three characteristics of alphabet letters -- their frequency in printed materials, order in the alphabet, and visual similarity to other letters -- relate to children's letter-name knowledge in four languages with three…

We examined the predictive value of early spelling for later reading performance by analyzing data from 970 U.S. children whose spelling was assessed in the summer following the completion of kindergarten (M age = 6 years; 3 months). The word reading performance of most of the children was then tested after the completion of Grade 1 (age 7;5),…

It has been suggested that children acquire spelling by picking up conditional sound-spelling consistencies. To examine this hypothesis, we investigated how variation in word characteristics (words that vary systematically in terms of phoneme-grapheme correspondences) and child factors (individual differences in the ability to extract…

The Double Deficit Hypothesis of dyslexia is one approach to classifying students with reading disabilities. The theory offers four distinct groups of readers: (a) average readers, (b) students with phonological deficits, (c) students with naming speed deficits, and (d) students with double deficits: those having both (b) and (c). This study…

We examined whether young children acquire orthographic knowledge during structured adult-led storybook reading even though minimal viewing time is devoted to print. Sixty-two kindergarten children were read 12 storybook "chapters" while their eye movements were tracked. Results indicated that the children quickly acquired initial mental…

The relationship between linguistic experience and phonemic representations in spelling was investigated in two groups of Mandarin-English bilingual children (aged 5-6 years) who spoke mostly Mandarin-L1 (n = 23) or mostly English-L1 (n = 27) at home. A 60-item cloze task including high- and low-frequency words with word-initial and word-final…

Children's early spelling attempts (invented spellings) and underlying component skills were evaluated in a sample (N = 115) of 5-year-old children. Letter-sound knowledge and phoneme awareness were shown to be important predictors of invented spelling performance in this age group. The results also showed associations between invented spelling…

We conducted behavior?genetic analyses of kindergarten reading, spelling, phonological awareness, rapid naming, and spoken sentence processing in 172 pairs of monozygotic and 153 pairs of same-sex dizygotic twin kindergarten children sampled in the United States and Australia. We also modeled progress from preschool to kindergarten in…

In two separate studies, 100 South Korean kindergartners and 100 second graders were administered tests of speed of processing and phonological-processing skills as well as a Korean Hangul reading test. Speed of processing tasks were significantly correlated with most of the reading-related tasks but not with Hangul reading itself. Across studies,…

This study investigates the relationship between phoneme awareness and rapid naming skills and subsequent reading and spelling ability in two developmental periods: kindergarten to Grade 1 and Grade 1 to Grade 2. Two groups of children participated in the study: children at high and children at low familial risk of developmental dyslexia. The…

One goal of this longitudinal study was to examine whether the predictors of reading skills in Grade 3 would differ between English as a second language (ESL) students and native English-speaking (L1) students. Phonological processing, syntactic awareness, memory, spelling, word reading, and lexical access skills were assessed in kindergarten and…
