In this study, we examined the accuracy and consistency of Greek-speaking children with spelling difficulties using a spelling level-matched design at two time points. Eighty-seven children were selected for inclusion in three groups: a group with spelling difficulties (SpD, n = 22 fifth graders) and two control groups, a chronological age-matched…

Spelling poses a challenge to Arabic-speaking learners due to the complexity of the morphological and orthographic systems in Arabic. Arabic morphology has been argued to play a critical role in spelling since its morphological operations are built on a system consisting of a root that is interlocking into different patterns of vowels to form…

Three experiments using a spelling error detection task investigated the extent to which morphemes and pseudomorphemes affect word processing. We compared the processing of transparent compound words (e.g., doorbell), pseudocompound words (e.g., carpet), and matched control words (e.g., tomato). In half of the compound and pseudocompound words,…

Morpheme-based literacy training programs are widely used in German primary schools. This study investigated whether (1) morphological training is effective early in development (Grade 2) and (2) literacy gains can be attributed to advanced morphological processing. Fifty-two German-speaking second-graders participated in an eight-week…

Background: Middle school students use the information conveyed by morphemes (i.e., units of meaning such as prefixes, root words and suffixes) in different ways to support their literacy endeavours, suggesting the likelihood that morphological knowledge is multidimensional. This has important implications for assessment. Methods: The current…

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…

Spelling is influenced by implicit cues, but less is known about variability in this reliance. We assessed whether the influence of three implicit cues on Dutch past tense spelling was moderated by grade, literacy, and format. An Auditory infinitive, Written infinitive, and Picture+cloze format was completed by 68 third-graders and 47…

The purpose of this research was to understand better how morphemic units are encoded and auto-organised in memory and how they are accessed during writing. We hypothesised that the activation of morphemic units would not depend on rule-based learning during primary school but would be determined by frequency-based learning, which is a process…

Patients with semantic dementia show a specific pattern of impairment on both verbal and non-verbal "pre-semantic" tasks, e.g., reading aloud, past tense generation, spelling to dictation, lexical decision, object decision, colour decision and delayed picture copying. All seven tasks are characterised by poorer performance for items that are…

Purpose: The purpose of this study was twofold. First, we investigated whether first-grade children evidenced morphological awareness and whether they used their knowledge of morphological relations to guide their spelling. Second, we sought to determine whether children's morphological awareness abilities were predictive of their performance on…

The central purpose of this three-paper dissertation was to explore the ability of school-age children with and without language-learning disabilities (LLD) to apply sound/word level structure knowledge when performing speaking, spelling, and reading tasks. Data came from a larger investigation that used stratified sampling to create two ability…

Two experiments and two corpus studies focus on homophone dominance in the spelling of regularly inflected verb forms, the phenomenon that the higher-frequency homophone causes more intrusion errors on the lower-frequency one than vice versa. Experiment 1 was a speeded dictation task focusing on the Dutch imperative, a verb form whose formation…

Two studies examined whether young children use their knowledge of the spelling of base words to spell inflected and derived forms. In Study 1, 5- to 9-year-olds wrote the correct letter (s or z) more often to represent the medial /z/ sound of words derived from base forms (e.g., "noisy," from "noise") than to represent the medial /z/ sound of…
