“…Mean consistency of grapheme-phoneme associations for French words (token-based, i.e., weighted by word frequency) was 83% (2% of words were excluded from the analysis because they were not present in the database; Manulex-infra, Peereman, Lete, & Sprenger-Charolles, 2007). Grapheme-phoneme consistency for German words could not be calculated since to our knowledge, no equivalent measure is available.…”

Referred to as orthographic depth, the degree of consistency of grapheme/phoneme correspondences varies across languages from high in shallow orthographies to low in deep orthographies. The present study investigates the impact of orthographic depth on reading route by analyzing evoked potentials to words in a deep (French) and shallow (German) language presented to highly proficient bilinguals. ERP analyses to German and French words revealed significant topographic modulations 240-280 ms post-stimulus onset, indicative of distinct brain networks engaged in reading over this time window. Source estimations revealed that these effects stemmed from modulations of left insular, inferior frontal and dorsolateral regions (German > French) previously associated to phonological processing. Our results show that reading in a shallow language was associated to a stronger engagement of phonological pathways than reading in a deep language. Thus, the lexical pathways favored in word reading are reinforced by phonological networks more strongly in the shallow than deep orthography.

In the present study, conducted with French-speaking children, we examined the reliability (group study) and the prevalence (multiple-case study) of dyslexics' phonological deficits in reading and reading-related skills in comparison with Reading Level (RL) controls. All dyslexics with no comorbidity problem schooled in a special institution for children with severe reading deficits were included in the study (N = 15; Chronological Age [CA]: 111 +8 months; RL: 80 +3 months). For the group study, the 15 dyslexics were matched pairwise on reading level, non-verbal IQ, and gender to 15 younger RL controls (CA: 85 +4 months). For the multiple-case study, the RL control group included 86 average readers (CA: 83 +4 months; RL: 85 +5 months). To assess the relative efficiency of the sublexical (or phonological) and lexical reading procedures, we relied on two comparisons: pseudowords vs. high-frequency regular words (the comparison mainly used in languages with a shallow orthography); and pseudowords vs. high-frequency irregular words (the comparison mainly used with English-speaking dyslexics), pseudowords and irregular words being either short or long. The dyslexics' skills in the domains supposed to explain their reading deficit were also examined: phonemic awareness, phonological short-term memory and rapid naming. In the group study, the dyslexics lagged behind the RL controls only when they were required to read long pseudowords. The results of the multiple-case study indicated that the prevalence of this deficit was high (the accuracy scores of all but 2 of the 15 dyslexics being more than 1 SD below the RL control mean), and that deficits in phonemic awareness were more prevalent (7 cases) than deficits in phonological memory (1 case) and in rapid naming (2 cases). Three unexpected results were observed in the group study: the difference between regular words and pseudowords (to the detriment of pseudowords) was not greater for the dyslexics; the difference between irregular words and pseudowords (to the benefit of pseudowords) was more significant for the RL controls; and there were no significant differences between the groups in reading-related skills. To explain these results, the severity of the dyslexics' reading deficit and the remediation they have benefited from must be taken into account. In addition, the fact that the outcomes of the comparison between pseudoword vs. regular or irregular word reading were not the same will make it possible to understand some discrepancies between studies carried out either in English or in a language with a shallower orthography (French, for instance).

“…Il définit la polygraphie comme le degré de transparence contenue dans les C.P.G., ce qui en fait une mesure statistique et donc objective, à l'instar de la consistance telle qu'elle a pu être présentée dans diverses études ou bases de données consacrées au français (e.g. Lété, 2008 ;Lété, Sprenger-Charolles & Colé, 2004 ;Peereman & Content, 1998, 1999Peereman, Lété & Sprenger-Charolles, 2007 ;Ziegler, Jacobs & Stone, 1996). Dans le cadre de cet article, malgré son ambigüité soulignée par Kreiner (1996) et en raison de son utilisation majoritaire dans la littérature (Bonin et al, 2008), nous utilisons le terme consistance au détriment de polygraphie.…”
