The current study explores the interplay between central and peripheral processes in second language (L2) handwriting among bilinguals with diverse orthographic backgrounds. Our investigation delves into the cross-linguistic transfer effect in Spanish–English and Chinese–English bilinguals, emphasizing lexical frequency and phoneme-grapheme (P-O) consistency in spelling-to-dictation and immediate copying tasks. Results reveal that the interaction between central and peripheral processes in L2 handwritten production is shaped by the bilinguals' native language (L1) orthographic characteristics. Spanish–English bilinguals exhibited sensitivity to P-O consistency and the spread of this effect from central to peripheral processes throughout both tasks. Conversely, Chinese–English bilinguals showed heightened sensitivity to lexical frequency during orthographic planning and motor execution, particularly in the immediate copying task. In a broader context, these findings suggest that the parallel and cascading coordination of the L2 writing system is modulated by cross-linguistic variations. The implications of our findings hold relevance for handwriting production and bilingualism research.

Different studies have demonstrated that people with dyslexia have difficulties in acquiring fluent reading and writing. These problems are also evident when they learn a second language. The aim of our study was to investigate if there is a linguistic transfer effect for writing in children with dyslexia when they face tasks in English (L2), as well as the possible influence of other linguistic skills (spelling, vocabulary and reading) in English (L2) and in Spanish (L1). Participants completed a series of tasks both in Spanish and English: a picture naming task, a word reading task, a word spelling task, and a written composition of which we analysed its quality through different variables provided by the Coh-metrix software. Our results revealed that children with dyslexia show similar or parallel performance in written composition in both languages, which could imply a language transfer effect from L1 and L2. Besides, basic language skills are related to the characteristics of written composition to a greater extent in English than in Spanish, suggesting the impact of these on the quality of written composition.

Previous work in English has found that the spelling difficulties of children with dyslexia affect the overall quality attributed to their written compositions. The aim of this study was to investigate whether different processes related to transcription, translation and ideas proposing/planning are affected in developmental dyslexia and to what extent potential deficits are associated to poor spelling. Compositions handwritten by Spanish-speaking children with and without dyslexia aged 9-12 years-old (n = 42) were compared on measures of productivity, spelling accuracy, legibility, lexical diversity, punctuation, sentence structure and grammar, organisation, ideas quality, and readability. Children with dyslexia performed worse in spelling, lexical diversity, syntax and grammar and ideas quality. Interestingly, in the group with dyslexia spelling accuracy contributed to lexical diversity, while lexical diversity was the only significant predictor of syntax and grammar, organisation and ideas quality. This pattern of results was absent in typically developing children. This evidence suggests that spelling difficulties are associated to reduce the lexical diversity of the texts of children with dyslexia, which may affect the activity of the translator and the proposer, diminishing the perceived quality of their written compositions.

Spelling and handwriting are different processes; however, they are learned simultaneously, and numerous studies have shown that they interact. Besides the commonly reported presence of a spelling deficit, previous studies have indicated that handwriting difficulties can also be detected in children with dyslexia. Despite this, this issue has not been sufficiently explored. The goal of the study was to investigate the potential handwriting difficulties met by children with dyslexia and how they might relate to spelling difficulties and to basic graphic skills. Twenty children with dyslexia were compared with a chronological age-matched group and reading level-matched group. Participants completed a spelling-to-dictation task of words and pseudowords, an alphabet writing task, and two graphic tasks. Results showed that children with dyslexia were less accurate and slower in preparing and executing the written response than typically developing peers, but they showed the spelling level expected given their reading ability. Children with dyslexia also performed similarly to children with the same reading level in the alphabet and graphic tasks, with both groups being slower and less fluent than the control age group. Altogether, the results suggest the existence of a delay in the development of handwriting and graphic fluency related to the level of reading and spelling skills rather than the presence of a core deficit affecting fine motor skills in dyslexia. In this sense, it seems that reduced literacy skills can affect the development of other skills that are usually enhanced with handwriting practice, such as fine motor skills.

The present study addresses how handwriting speed increases with age among Spanish 8-, 10- and 12-year-old children (n = 60), and how this progression is related to spelling and more general graphic skills. Handwriting speed was measured in a spelling-to-dictation and a copying task, and graphic speed was measured in a trail tracing task. Results revealed that handwriting speed significantly increased from age 8 to 10 and remained stable up to 12 years of age, while graphic speed substantially increased only between 10 and 12 years of age. Thus, handwriting speed and graphic speed do not seem to follow the same pattern of development. Moreover, the relationship between linguistic processes and graphic skills with handwriting speed was not the same for all the groups. In the younger group, a different speed profile was obtained for each task, while in the groups of 10- and 12-year-olds, speed was similar in all the linguistic tasks. Graphic speed was positively correlated with speed in the spelling task only around the age of 10, and by age of 12 graphic speed correlated negatively when handwriting neatness was prioritized. Altogether, these results show that handwriting speed becomes consistent around the age of 10, when it is mostly affected by spelling ability and, in some circumstances, by graphic speed. By the age of 12, speed in linguistic tasks becomes decoupled from graphic speed and it is adapted depending on the relative importance of neatness and speed for the task. 

It is widely assumed that by identifying spelling errors and suggesting replacement words, spellcheck allows writers to revise spelling errors even if they do not have the necessary spelling knowledge. However, there have been no studies evaluating the efficacy of modern spellcheck tools for students with spelling difficulties, such as dyslexia. In fact, the very limited and dated research into use of spellcheck by writers with dyslexia indicated that, even when using spellcheck to revise spelling errors, this group left many misspellings in their texts. The current study is the first to investigate whether a modern spellcheck program allows college students with dyslexia to produce texts that are as free from misspellings as texts by their peers, and whether this affects the quality of the text in other ways.

College students with dyslexia (n=18) and a control group of peers (n=18) wrote two short essays using Microsoft Word, one with spellcheck active and one without spellcheck active. Spelling accuracy and overall quality of the texts were measured. Without spellcheck, students with dyslexia made more misspellings than the control group, however, with spellcheck active students from both groups left almost zero misspelled words in their texts. Text quality was not affected. Results demonstrate that spellcheck helps college students with dyslexia to overcome the limitations that poor spelling knowledge imposes. Importantly, results indicate that spellcheck does not lead to improvements in text beyond spelling accuracy, or lead to poorer quality texts, indicating that it is suitable for use in exam conditions.

Previous literature has indicated that linguistic and motor processes influence each other during written sentence production, and that the scope of this influence varies according to spelling ability or cognitive resources available. This study investigated how the spelling deficits associated with dyslexia affect the dynamics of the interaction between central and peripheral processes and the level of anticipation that can be observed in word spelling in the context of a sentence to dictation task. Children 9-12 year-olds with and without dyslexia wrote sentences to dictation in which the lexical frequency and phonology-to-orthography consistency of the last word (target) were manipulated. Analyses of kinematic measures (writing durations, in-air pen duration, and peaks of speed) revealed that children with dyslexia showed lexical frequency effects evident in within-word pauses (in-air pen) in the article and noun production. In addition, both children with and without dyslexia showed a phonology-to-orthography consistency effect in the pause before the target word. This effect tended to continue affecting the execution of the syllable prior to the inconsistency only in the group with dyslexia. Results support the influence of linguistic processes on motor execution. In addition, the study provides evidence of the impact of spelling deficits on the dynamics of handwriting in children with dyslexia.

Several studies have yielded fine-grained insights on the embodied dynamics of language by revealing how processing of manual action verbs (MaVs) affects the programming or execution of concurrent hand movements. However, virtually all extant studies have relied on highly contrived dual tasks in which independent motoric and linguistic processes are arbitrarily related. To circumvent potential attentional confounds, we conducted the first assessment of motor-language integration during handwriting, an early acquired skill that necessarily integrates both types of processes. Using a digital pen, participants copied carefully matched MaVs, non-manual action verbs, and non-action verbs as we collected measures of motor programming (the time needed to start the writing routine after verb presentation) and motor execution (the time needed to write the whole verb). Whereas motor programming latencies were similar across conditions, the unfolding of motor routines was faster for MaVs than for the other two categories, irrespective of the subjects’ daily writing time. Moreover, this effect remained consistent regardless of whether word meanings were accessed implicitly or explicitly. In line with the Hand-Action-Network Dynamic Language Embodiment (HANDLE) model, such findings suggest that everyday manual movements can be primed by effector-congruent verbs, even in a highly automatized task that seamlessly combines linguistic and motoric processes. In addition, this effect differs from that observed for MaVs in a previous (keyboard-based) typing experiment, suggesting that language-induced sensorimotor resonance during writing depends on the motoric particularities of each production modality. More generally, our paradigm opens new avenues for fine-grained explorations of embodied language processes.

The debate about whether compound words are accessed as whole-words or via their constituents remains unresolved, especially in the field of language production. In the present study, three experiments using a copying task examined whether compound words are accessed via their constituents in handwriting production. In Experiment 1, production of compound words and noncompounds was compared. The last inter-letter interval within the first constituent of compounds was observed to be shorter than the same interval in noncompounds, revealing that writing durations are sensitive to morphological processing. In Experiments 2 and 3, the first and second constituent frequency was manipulated respectively. The frequency of both constituents affected writing onset times. Interestingly, the interval between the last two letters of the first constituent was shorter when the second constituent was of high-frequency, suggesting that the effect obtained in this position in Experiment 1 was related to the anticipation of the second constituent. Our findings indicate that both constituents are activated before the initiation of the written response and that the second component is reactivated before the production of the first constituent has finished.
