Purpose – In developmental dyslexia, spelling deficits have been much less explored than reading deficits, although the former tend to be more persistent than the latter. The aim of this study was to explore the ability to acquire new orthographic representations through different learning conditions in dyslexic children. Method – Fifteen dyslexic French-speaking children (mean chronological age: 11; 4 years; mean reading age: 7; 6 years), 15 chronological age (CA) and 15 reading age (RA) matched controls participated in the study. Their ability to acquire new orthographic representations was assessed through different learning conditions: isolated pseudowords decoding, text reading with embedded target pseudowords and writing of pseudowords after presentation in their visual form associated or not to a semantic representation. In each condition, ten target pseudowords were presented six times. Orthographic learning was measured by a dictation of the targets immediately after the learning session and one week later. Results – Orthographic learning of dyslexics was significantly impaired and decreased more over time relative to CA group but not to RA group. Otherwise, dyslexics, as other groups, performed better when learning conditions consisted in writing pseudowords than in decoding them. Furthermore the condition associating a semantic representation to the pseudowords did not enhance the performances in any group. Conclusion – These results confirm that decoding abilities are essential to develop orthographic representations and suggest that writing is a powerful learning mechanism in dyslexic as in normal readers. By contrast, a semantic representation seems not to support the development of orthographic representations. [less ▲]Detailed reference viewed: 51 (13 ULg)

Most of the children attending bilingual immersion school programs in the French Community of Belgium learn to read in the immersion language before learning to read in their native language. This study aimed to explore the effect of learning to read in a second language having a transparent (Dutch) versus an opaque (English) orthographic code, on the later acquisition of French spelling. Because literacy acquisition depends on the orthographic depth of the code, the hypothesis is that learning to spell in a transparent language such as Dutch would promote the acquisition of the more opaque French spelling, by transferring the phonological recoding process. Contrariwise, the acquisition of French spelling would be less easy if learners were first immersed in very opaque spelling such as English. Participants were 182 third and fourth-graders immersed in Dutch or English, and monolingual French speakers (control group). Their French spelling skills were tested by words and non-words dictation. Results showed that the performance of Dutch immersed children was not significantly inferior to controls, which is not the case for English immersed children. This corroborates the fact that learning to spell in a more transparent orthographic code than French has a subsequent benefit on its acquisition. [less ▲]Detailed reference viewed: 18 (5 ULg)

Inflectional spelling abilities have been less extensively studied than lexical spelling abilities and the relationship between these two types of spelling abilities is poorly understood. In this study, we compared lexical and inflectional spelling abilities in 12-year-old children, by hypothesizing that attentional load may be particularly detrimental for sentence context-dependent inflectional spelling abilities, in contrast to sentence context-independent lexical spelling abilities. Ninety-five sixth graders had to write to dictation sentences containing orthographically inconsistent words as well as inflected words (plural nouns and verbs at the 3th person) in three different cognitive load conditions. In a medium load condition, a time constraint obliged the subjects to write the sentences as quickly as possible. In a high load condition, the participants had to write the sentences as quickly as possible while further carrying out calculation problems (additions). The minimal load condition corresponded to standard writing to dictation, with no time constraint or any secondary task. The number of spelling errors for orthographically inconsistent words (lexical spelling abilities) and inflected words (inflectional spelling abilities) was calculated for each condition. We observed that spelling performance for inconsistent words was not impacted by cognitive load. On the other hand, spelling performance for inflected words decreased significantly in the medium and high load conditions. These results suggest that inflectional spelling abilities are less proceduralized than lexical spelling abilities, and rely to a greater extent on cognitive control processes.
