OVP : permet de mieux comprendre les processus impliqus dans le dcodage des mots.Mais peut aussi tre utilis des fins plus pratiquesExemple : la lecture chez lenfant sourd.

Grandes tapes du dveloppement oral chez lenfant entendant7-11 mois :Babillage syllabique11-14 mois:Premier mot16-22 mois:2 motstapes suivantes: grammaire, syntaxeApprentissagede lcrit = ovp

Etapes similaires chez lenfant sourd :Vers 6 mois :Babillage sign et oralVers 12 mois:Premier signeVers 16 mois:2 signestapes suivantes: combinaisons de signes, syntaxe de la langue des signestapes pr-linguistiquestapes linguistiques80 % dillettrisme !

The question whether thought is possible without language The Principles of Psychology, William James (1890).La pense est-elle possible sans langage, sous entendu, les personnes sourdes nont pas de langage.Dveloppement de loralisation

Observations de Broca sur des patients aphasiques (qui comprennent le langage mais ne parlent pas) : dbut de la localisation crbrale.Les diffrentes fonctions du cerveau sont localises anatomiquement.Conception rigide de lorganisation crbrale. Plasticit neuronale

Deux types de signes :- symbole linguistique (quivalent du mot chez lenfant signeur)- geste communicatif, couramment utilis par les bb. Mme modalit que le symbole sign linguistique, formellement identique.Les enfants sourds distinguent ces deux types de gestes et les utilisent de manire diffrentes.

Distribution bi-modale chez les enfants exposs la langue des signesActivit motrice pr-langagire, en rapport avec la segmentation, le rythmeDcomposition en syllabe, mots, phrasesBabillage = activit linguistique et non pas purement motrice

Phonetic and Gestural Method of Borel-Maisonny (Silvestre de Sacy, 1978). This program helps the child to identify speech segments and to link them to their written counterparts. Each phoneme of the language is correlated to a combination of lip movements and hand gestures.

Plusieurs hypothses concernant lOVP : habitudes de lecture (T.Nazir) contraintes lexicales spcialisation hmisphrique

Les habitudes de lecture. (T.Nazir) sens de lecture : gauche vers la droite associ un dplacement de lattention asymtrie de lempan=> Orientation de lattention vers la droite, l o se trouve linfo utile OVP invers en hbreux et en arabe

Les contraintes lexicales. les mots peuvent tre reconnus partir des premires lettres plus haut degr de contraintes lexicales au dbut des mots que vers la fin lorsque les mots taient contraints par leurs lettres finales, lOVP tendait se dplacer sur la droite, en fin de mot

La spcialisation hmisphrique temps de transfert inter-hmisphrique interaction entre la visibilit des lettres (diminuant avec l'loignement du centre) et la supriorit du champ visuel droit (CVD) pour le traitement des informations linguistiques

Hypothse de la spcialisation hmisphrique repose sur la notion de Split FovaLa question fondamentale qui se pose est la suivante :Est-ce que linformation visuelle perue en vision fovale est projete vers les 2 hmisphres (reprsentation bilatrale) ou au contraire est-elle latralise (split fova) ?
