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)…

As children learn to read, they become sensitive to context-dependent vowel pronunciations in words, considered a form of statistical learning. The work of Treiman and colleagues demonstrated that readers' vowel pronunciations depend on the consonantal context in which the vowel occurs and reading experience. Using explanatory item-response models…

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…

We investigated how and when French children in Grades 1-5 acquire orthographic representations for silent letters and double consonants. Linear mixed-effects modeling analyses on the spelling accuracy scores obtained for 2,519 French words were used to test our predictions. As predicted, the presence of a silent letter or double consonant had a…

Statistical learning has been proposed to underlie the developmental transition during infancy from allophonic to phonemic speech sound perception. Based on this, it can be hypothesized that in dyslexic individuals, core phonemic representation deficits arise from reduced sensitivity to the statistical distribution of sounds. This study aims to…

We assessed nonword repetition (NWR) skills in 7-9 year-old children with dyslexia (dyslexia-only), developmental language disorder (DLD-only), co-occurring DLD+dyslexia, and typical development (TD) with a norm-referenced and an experimental task. The experimental task manipulated phonemic variability (dissimilarity among consonant phonemes…

Purpose: This study was designed to assess the efficiency of a French version of "GraphoGame" (GG) against an equally engaging math intervention ("Fiete Math," FM) in a large school sample of children from socioeconomically disadvantaged neighborhoods in grade 1 (N = 921). Method: The intervention was implemented in two…

This study examined Spanish spelling errors among 166 native Spanish-speaking students from Kindergarten to Grade 3 based on a spelling-to-diction task. Fifteen types of spelling errors were analyzed in a latent class analysis. Results suggested three phases of spellers: Phase 1 students had a high chance of committing almost all types of errors.…

Potential implicit orthographic learning deficits were investigated in adults with dyslexia. An artificial grammar learning paradigm served to assess dyslexic and typical readers' ability to exploit information about chunk frequency, letter-position patterns, and specific string similarity, all of which have analogous constructs in real…

We investigated how letter length, phoneme length, and consonant clusters contribute to the word length effect in 2nd- and 4th-grade children. They read words from three different conditions: In one condition, letter length increased but phoneme length did not due to multiletter graphemes (H"aus"-B"auch"-S"chach"). In…

We examined the manifestation of dyslexia in a cross-linguistic study contrasting English and Greek children with dyslexia compared to chronological age and reading-level control groups on reading accuracy and fluency, phonological awareness, short-term memory, rapid naming, orthographic choice, and spelling. Materials were carefully matched…

Visual attention span (VAS) predicts reading performance over and above phonological skills. Given the growing number of studies that include VAS, it is surprising that indications of the stability of VAS performance and its relation with reading over time have not yet been reported. The current study addressed these important issues. Participants…

In polysyllabic languages the assignment of stress is crucial for understanding the reading process. Here we review empirical evidence, drawn mainly from studies on Italian, and discuss critical issues in understanding reading. We first discuss the lexical and sublexical mechanisms responsible for stress assignment and propose that the former is…

When readers search for misspellings in a proofreading task or for a letter in a letter detection task, they are more likely to omit function words than content words. However, with misspelled words, previous findings for the letter detection task were mixed. In two experiments, the authors tested the functional equivalence of both tasks. Results…

One influential theory of literacy development, the constructivist perspective, claims that young children believe that writing represents meaning directly and that the appearance of a written word should reflect characteristics of its referent. There has not been strong evidence supporting this idea, however. Circumventing several methodological…
