YesObjective\ud \ud This study explores whether the profile of patients’ interactional behaviour in memory clinic conversations with a doctor can contribute to the clinical differentiation between functional memory disorders (FMD) and memory problems related to neurodegenerative diseases.\ud \ud Methods\ud \ud Conversation Analysis of video recordings of neurologists’ interactions with patients attending a specialist memory clinic. “Gold standard” diagnoses were made independently of CA findings by a multi-disciplinary team based on clinical assessment, neuropsychological testing and brain imaging.\ud \ud Results\ud \ud Two discrete conversational profiles for patients with memory complaints emerged, including (i) who attends the clinic (i.e., whether or not patients are accompanied), and (ii) patients’ responses to neurologists’ questions about memory problems, such as difficulties with compound questions and providing specific and elaborated examples and frequent “I don’t know” responses.\ud \ud Conclusion\ud \ud Specific communicative difficulties are characteristic of the interaction patterns of patients with a neurodegenerative pathology. Those difficulties are manifest in memory clinic interactions with neurologists, thereby helping to differentiate patients with dementia from those with FMD.\ud \ud Practical implications\ud \ud Our findings demonstrate that conversational profiles based on patients’ contributions to memory clinic encounters have diagnostic potential to assist the screening and referral process from primary care, and the diagnostic service in secondary care

“…This effect, referred to in the literature as the "age of acquisition" effect (AoA effect), has been reported in many lexical processing tasks including: oral and written picture naming (e.g., Barry, Morrison, & Ellis, 1997;Bonin, Fayol, & Chalard, 2001;Ellis & Morrison, 1998;Morrison, Chappell, & Ellis, 1997;Severens, Van Lommel, Ratinckx, & Hartsuiker, 2005), face naming (e.g., Moore & Valentine, 1998), word naming (e.g., Gilhooly & Logie, 1981Morrison & Ellis, 1995, category instance fluency (Catling & Johnston, 2005;Forbes-McKay, Ellis, Shanks, & Venneri, 2005;Loftus & Suppes, 1972), word completion (Gilhooly & Gilhooly, 1979), visual and auditory lexical decision (e.g., Morrison & Ellis, 1995Turner, Valentine, & Ellis, 1998), naming from definition (Sartori, Lombardi, & Matiuzzi, 2005) or perceptual identification (Lyons, Teer, & Rubenstein, 1978). Moreover, although AoA measures are related to other lexical variables, at least in word naming and lexical decision tasks, AoA effects have been found to be independent of different measures of word frequency, familiarity, imageability and word length (Morrison & Ellis, 2000).…”

Since the early seventies, several studies have suggested that the age at which words are acquired (age of acquisition, or AoA) is an important predictor of the speed and accuracy with which those words can subsequently be processed in adulthood, with words acquired early in life being processed faster and more accurately than words acquired later (e.g., Carroll & White, 1973b).This effect, referred to in the literature as the "age of acquisition" effect (AoA effect), has been reported in many lexical processing tasks including: oral and written picture naming (e.g., Barry, Morrison, & Ellis, 1997;Bonin, Fayol, & Chalard, 2001;Ellis & Morrison, 1998;Morrison, Chappell, & Ellis, 1997;Severens, Van Lommel, Ratinckx, & Hartsuiker, 2005), face naming (e.g., Moore & Valentine, 1998), word naming (e.g., Gilhooly & Logie, 1981Morrison & Ellis, 1995, category instance fluency (Catling & Johnston, 2005;Forbes-McKay, Ellis, Shanks, & Venneri, 2005;Loftus & Suppes, 1972), word completion (Gilhooly & Gilhooly, 1979), visual and auditory lexical decision (e.g., Morrison & Ellis, 1995Turner, Valentine, & Ellis, 1998), naming from definition (Sartori, Lombardi, & Matiuzzi, 2005) or perceptual identification (Lyons, Teer, & Rubenstein, 1978). Moreover, although AoA measures are related to other lexical variables, at least in word naming and lexical decision tasks, AoA effects have been found to be independent of different measures of word frequency, familiarity, imageability and word length (Morrison & Ellis, 2000).The measurement of AoA has been operationalized in two different ways: a "subjective" measure, corresponding to adult ratings of the AoA of different words; and an "objective" measure based on the performance of children of different ages in object naming tasks. Several studies have shown that both measures of AoA are strongly correlated in different languages (e.g., Carroll & White, 1973a; De Moor, Ghyselink, & Brysbaert, 2000;Jorm, 1991;Lyons et al., 1978;Morrison et al., 1997;Pérez & Navalón, 2005;Pind, Jonsdottir, Gissurardottir, & Jonsson, 2000) providing validation for the rating method. Moreover, Bonin, Barry, Méot, and Chalard (2004) showed that the two measures were still significantly correlated when other lexical variables associated with AoA (including conceptual familiarity, word frequency trajectory, cumulative word frequency, imageability and phonological length) were partialled out.All this evidence would seem to suggest that AoA is an important lexical dimension on its own that can be measured in (at least) two different ways and that influences performance on a very diverse set of tasks. However, both of these contentions are still a matter of ongoing theoretical and methodological debate. On one hand, several criticisms have been pointed out to the two AoA measures and a new measure, "frequency trajectory", has been proposed to examine age-limited learning effects (Bonin et al., 2004;Zevin & Seidenberg, 2002). On the other hand, the independence of AoA and of AoA effects have been contested, esp...

“…En lien avec les travaux antérieurs, nos hypothèses sont validées (Marczinski & Kertesz, 2006 ;Forbes-McKay et al, 2005, Kremin et al,2001Lymperopoulou et al, 2006). Les études sur la fréquence avaient déjà mis en avant une plus grande aisance pour le traitement des mots fréquents par les patients Alzheimer ; dans une tâche de dénomination d'images, les sujets atteints de la maladie d'Alzheimer et les sujets sains réagissent de manière similaire face à des mots fréquents, mais de grandes disparités apparaissent dès lors que les mots présentés sont non fréquents (Balota, Burgess, Cortese, Adams, 2002).…”

“…La réponse est partagée entre problème d'accès à la mémoire sémantique d'une part (Pasquier, Lebert, Grymonprez, Petit, 1995 ;Nebes, 1989), et problème de connexion à l'intérieur même du réseau, d'autre part (Hodges & Patterson, 1995 ;Forbes-McKay et al, 2005 ;Rosser & Hodges, 1994 ;Rascovsky, Salmon, Hansen, Thal, Galasko, 2007). Les chercheurs soutenant la première hypothèse proposent que l'effet d'indiçage, souvent observé chez les personnes atteintes de la maladie d'Alzheimer, est la preuve d'un réseau intact mais d'un accès difficile.…”

Melissa.Barkat-Defradas@univ-Montp3.fr Résumé. Le but de cette étude est d'observer les effets de fréquence et d'âge d'acquisition dans les productions de sujets francophones atteints de la maladie d'Alzheimer et de sujets âgés sains lors d'exercices requérant la recherche, la récupération et l'activation du lexique en mémoire sémantique. Pour ce faire, nous avons soumis nos sujets à deux tâches de fluence verbale : une sémantique (animaux) et l'autre littérale (P). Les résultats montrent que les sujets atteints de la maladie d'Alzheimer réussissent moins bien que les sujets contrôles la recherche sémantique (vs littérale) et produisent moins de mots que les sujets sains. Leurs productions contiennent également des mots plus fréquents et acquis plus tôt que les mots produits par les sujets sains. Une régression logistique montre que l'âge d'acquisition à lui seulnest capable de prédire le groupe d'appartenance d'un sujet.
