Abstract(s) :

(Anglais) Investigating the efficiency of reading aloud components of single words in Alzheimer’s disease Aurelia Rendón de la Cruz1, Isabelle Simoes Loureiro1, Mandy Rossignol1 & Laurent Lefebvre1 1Cognitive psychology and neuropsychology department, Institute of health sciences and technologies, University of Mons, Mons, Belgium aurelia.rendondelacruz@umons.ac.be Several studies have highlighted a word recognition impairment in Alzheimer’s disease (AD), particularly for low frequency exception words (regularization errors) and pseudowords (lexicalization errors) (Graham & Patterson, 2004). A few studies 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. Indeed, they do not necessarily consider the five subprocesses of reading, which are the visual, orthographic, phonological, lexico-semantic processing and the phonological buffer. Therefore, the aim of this project is to systematically investigate these subprocesses throughout AD, to explore the efficiency of each one of them by using tasks that selectively rely on these components. A French word reading aloud task and five tasks, each focusing on one reading component, will be developed. They will be administered to three groups: mild AD, moderate AD and a control group matched for age, sex and education. The word reading task is a computer task which comprises regular and exception words, pseudowords (with and without neighbors) and pseudohomophones (half derived from regular words and half derived from exception words). The same set of stimuli are used within all tasks. The five tasks comprise (1) a letter comparison task to assess visual processing in reading (2) a lexical decision task to evaluate the orthographic input lexicon (3) a semantic word-matching task assessing lexico-semantic processing (4) a semantic exception-word matching task designed to assess the phonological output lexicon and (5) a pseudoword (long and short) repetition task to evaluate the phonological buffer.
