Vortrag von Sonia Kandel am Dienstag, 27.11.2012, 16-18 Uhr

Sonntag, 18. November 2012. Aus der Kategorie 'Vortragsreihe'. Das Sprachwissenschaftliche Institut lädt ein zu dem Vortrag von Sonia Kandel (Grenoble): Towards an integrated approach of writing --
Although writing is an essential communication tool for living in society most research on language production has focused on speech communication and little is known on how we write words. In addition, written word production has been investigated by two distinct approaches that have hardly interacted. On one hand, spelling research studied the retrieval of orthographic codes from the mental lexicon. They were concerned about the central processes taking place before movement initiation. On the other hand, written production has been examined from a strictly motor perspective as the conversion of letters into movements that produce a graphic output. Orthographic representations were conceived as linear sequences containing information on letter identity and order so word writing consisted of programming one letter after another.

Our research attempts to integrate these two approaches. First, we collected a series of digitiser data with children and adults indicating that the orthographic representations we activate to write a word are far more complex. They code groups of letters that follow phonological and/or semantic coherence. We activate grapheme, syllable and morpheme letter chunks that modulate motor programming. So the movement to write a letter will not only depend on its shape and the motor program that is activated to produce it but also on linguistic aspects. For example, writing letter A in the French word CLAVIER, where A = /a/, is different than in PRAIRIE because in this case AI = /ε/. In addition, graphotactic parameters such as bigram frequency may also affect motor programming. Second, central and peripheral processes may interact such that spelling activation may spread or cascade onto the motor regulation of writing. We investigated when central and peripheral processes interact and the locus of the interaction during written production.

Our findings suggest that not all spelling processes affect movement production in the same manner. Lexical and sublexical processing does not cascade to the same extent. The former affects the production of the initial letters of the word whereas the latter may regulate movement execution even until the final letters. This “integrated approach” of writing provides evidence that spelling and motor processes cannot be dissociated. Written production has to be investigated as a linguistic event.

Der Vortrag findet in Raum 3/159 statt.
