Abstract(s) :

(Anglais) P2.53- Assessment of word reading aloud subprocesses to better understand reading abilities in Alzheimer’s disease Aurelia Rendón de la Cruz, Isabelle Simoes Loureiro, Mandy Rossignol, & Laurent Lefebvre Institute of Health Sciences and Technologies, Université de Mons, Belgium Several studies have highlighted a word recognition impairment in Alzheimer’s disease (AD), particularly for low frequency exception words (regularization errors) and pseudo-words (lexicalization errors) (Graham & Patterson, 2004). A few of them have focused on the efficiency of the underlying processes involved in word reading aloud to better understand reading errors in AD. However, their results are partly contradictory as they do not consider the five subprocesses of reading, i.e., visual, orthographic, phonological, lexico-semantic processing and the phonological buffer. Therefore, the aim of this project is to systematically investigate these five subprocesses throughout AD. A French word reading aloud task and five tasks focusing on one reading component will be developed. They will be administered to three groups: mild AD, moderate AD and a control group. The word reading task comprises regular and exception words, pseudo-words (with and without neighbours) and pseudo-homophones (half derived from regular words and half derived from exception words). The five tasks involve (1) a letter comparison task (visual processing) (2) a lexical decision task (orthographic input lexicon) (3) a semantic wordmatching task (lexico-semantic processing) (4) a semantic exception-word matching task (phonological output lexicon) and (5) a pseudo-word repetition task to (phonological buffer).
