The Spelling Errors of French and English Children With Developmental Language Disorder at the End of Primary School.

ABSTRACT: Children with Developmental Language Disorder (DLD) often struggle learning to spell. However, it is still unclear where their spelling difficulties lie, and whether they reflect on-going difficulties with specific linguistic domains. It is also unclear whether the spelling profiles of these children vary in different orthographies. The present study compares the spelling profiles of monolingual children with DLD in France and England at the end of primary school. By contrasting these cohorts, we explored the linguistic constraints that affect spelling, beyond phono-graphemic transparency, in two opaque orthographies. Seventeen French and 17 English children with DLD were compared to typically developing children matched for age or spelling level. Participants wrote a 5 min sample of free writing and spelled 12 controlled dictated words. Spelling errors were analyzed to capture areas of difficulty in each language, in the phonological, morphological, orthographic and semantic domains. Overall, the nature of the errors produced by children with DLD is representative of their spelling level in both languages. However, areas of difficulty vary with the language and task, with more morphological errors in French than in English across both tasks and more orthographic errors in English than in French dictated words. The error types produced by children with DLD also differed in the two languages: segmentation and contraction errors were found in French, whilst morphological ending errors were found in English. It is hypothesized that these differences reflect the phonological salience of the units misspelled in both languages. The present study also provides a detailed breakdown of the spelling errors found in both languages for children with DLD and typical peers aged 5-11.

Project description:We aimed at unveiling the role of executive functions (EFs) and language-related skills in spelling for mono- versus multilingual primary school children. We focused on EF and language-related skills, in particular lexicon size and phonological awareness (PA), because these factors were found to predict spelling in studies predominantly conducted with monolinguals, and because multilingualism can modulate these factors. There is evidence for (a) a bilingual advantage in EF due to constant high cognitive demands through language control, (b) a smaller mental lexicon in German and (c) possibly better PA. Multilinguals in Germany show on average poorer German language proficiency, what can influence performance on language-based tasks negatively. Thus, we included two spelling tasks to tease apart spelling based on lexical knowledge (i.e., word spelling) from spelling based on non-lexical strategies (i.e., non-word spelling). Our sample consisted of heterogeneous third graders from Germany: 69 monolinguals (age: M = 108 months) and 57 multilinguals (age: M = 111 months). On less language-dependent tasks (e.g., non-word spelling, PA, intelligence, short-term memory (STM) and three EF tasks testing switching, inhibition, and working memory) performance of both groups did not differ significantly. However, multilinguals performed significantly more poorly on tasks measuring German lexicon size and word spelling than monolinguals. Regression analyses revealed that for multilinguals, inhibition was related to spelling, whereas switching was the only EF component to influence word spelling in monolinguals and non-word spelling performance in both groups. By adding lexicon size and other language-related factors to the regression models, the influence of switching was reduced to insignificant effects, but inhibition remained significant for multilinguals. Language-related skills best predicted spelling and both language groups shared those variables: PA for word spelling, and STM for non-word spelling. Additionally, multilinguals' word spelling performance was also predicted by their German lexicon size, and non-word spelling performance by PA. This study offers an in-depth look at spelling acquisition at a certain point of literacy development. Mono- and multilinguals have the predominant factors for spelling in common, but probably due to superior language knowledge, monolinguals were already able to make use of EF during spelling. For multilinguals, German lexicon size was more important for spelling than EF. For multilinguals' spelling these functions might come into play only at a later stage.

Project description:IntroductionSpelling difficulty is a common symptom of aphasia and can entail editing difficulties. Previous research has shown that extensive editing is related to a lower production rate in text writing for persons with aphasia, yet editing difficulty is not commonly examined. It is not known if editing difficulty is related to reading and writing skills or to aspects of the word.AimsTo analyse spelling and editing processes as well as errors in a dictation task performed by Swedish-speaking adults with post-stroke aphasia. Furthermore, the study aimed to identify any relationships between spelling and editing difficulties and characteristics of individual words. Finally, relationships between successful edits and reading and phonological ability were investigated and specific editing strategies or behaviours identified. Correlation analyses were performed between measures of spelling and editing and word frequency and length as well as participants' scores on tests of reading, phonological spelling and phonological decoding.Methods & proceduresA total of 16 Swedish speaking participants with post-stroke aphasia wrote a word-dictation task in a keystroke logging program and were tested for phonological spelling, phonological decoding and reading ability. Spelling errors were categorized and analysed.Outcomes & resultsThe most common error type was omission of letter(s) and there was evidence of aphasia-specific writing errors. Both spelling and editing difficulty were related to word frequency and word length. Successful editing was related to participants' scores on the phonological spelling task, but not to phonological decoding or reading ability. Specific editing strategies could be identified, and some strategies were individual, while others were more commonly used.Conclusions & implicationsWord length and word frequency should be taken into consideration in spelling tests for persons with aphasia, and the presence of editing difficulty should be taken into account when assessing spelling difficulties. Treatment for writing difficulties in aphasia should include training in successful editing strategies and individual fitting of digital writing aids. What this paper adds What is already known on the subject Post-stroke aphasia often causes writing and spelling difficulties. Spelling difficulties may entail editing difficulties, in turn causing extensive and/or unsuccessful editing. Extensive editing is known to impede productivity in text writing. Still, editing behaviour, abilities relating to editing or what features of a word that causes editing difficulty has not been investigated for persons with aphasia. What this paper adds to existing knowledge This study adds an in-depth analysis of spelling ability, spelling errors and editing behaviour for persons with aphasia, using keystroke logging and a single-word dictation task. Results showed that both features of the target word (frequency and word length) and the individual abilities of the person with aphasia (score on a phonological spelling task) related to spelling and editing difficulty, editing behaviour and successful editing. Specific editing strategies were analysed and described. What are the potential or actual clinical implications of this work? Word length and word frequency should be taken into consideration when testing single-word spelling for persons with aphasia. When assessing spelling difficulties, both correctness of spelling as well as the presence and nature of any editing difficulties should be taken into account and treatment for writing difficulties in should include training in successful editing strategies. The fitting of digital writing aids for persons with aphasia should be individual, since many of the editing strategies used were individual.

Project description:Predictors of treatment effects allow individual tailoring of treatment characteristics, thereby saving resources and optimizing outcomes. Electrical stimulation coupled with language intervention has shown promising results in improving language performance in individuals with Primary Progressive Aphasia (PPA). The current study aimed to identify language and cognitive variables associated with response to therapy consisting of language intervention combined with transcranial direct current stimulation (tDCS). Forty individuals with PPA received written naming/spelling intervention combined with anodal tDCS or Sham, using a between-subjects, randomized design, with intervention delivered over a period of 3 weeks. Participants were assessed using a battery of neuropsychological tests before and after each phase. We measured letter accuracy during spelling of trained and untrained words, before, immediately after, 2 weeks, and 2 months after therapy. We used step-wise regression methods to identify variables amongst the neuropsychological measures and experimental factors that were significantly associated with therapy outcomes at each time-point. For trained words, improvement was related to pre-therapy scores, in RAVLT (5 trials sum), pseudoword spelling, object naming, digit span backward, spatial span backward and years post symptom onset. Regarding generalization to untrained words, improvement in spelling was associated with pseudoword spelling, RAVLT proactive interference, RAVLT immediate recall. Generalization effects were larger under tDCS compared to Sham at the 2-month post training measurement. We conclude that, for trained words, patients who improve the most are those who retain for longer language skills such as sublexical spelling processes (phoneme-to-grapheme correspondences) and word retrieval, and other cognitive functions such as executive functions and working memory, and those who have a better learning capacity. Generalization to untrained words occurs through improvement in knowledge of phoneme-to-grapheme correspondences. Furthermore, tDCS enhances the generalizability and duration of therapy effects.
