La mémoire de reconnaissance visuelle (MRV) est atteinte précocement dans la maladie d'Alzheimer (MA). Or, elle reposerait sur deux processus : la familiarité (simple sentiment d'avoir déjà rencontré un item) et la recollection (récupération de détails associés à l'item lors de son encodage). Si la recollection est clairement atteinte au début de la MA, les résultats concernant la familiarité sont à ce jour contradictoires. Supposée plus rapide que la recollection, la familiarité devrait pouvoir être évaluée directement par une approche temporelle. Son atteinte dans la MA pourrait alors être mieux comprise.Pour tester ces hypthèses, la procédure comportementale SAB (Speed and Accuracy Boosting) a été créée. Permettant d'étudier les propriétés de la MRV (sa vitesse-limite, Articles 1 et 2, ou sa nature « bottom-up », Article 3), ainsi que l'hypothèse que la familiarité est plus rapide que la recollection, cette méthode s'est montrée évaluer majoritairement la familiarité (Article 1). Chez des patients à risque de MA, une dissociation inattendue au sein de la familiarité a alors pu être révélée, avec une atteinte des signaux tardifs de familiarité (utilisés lors d'un jugement classique), mais une préservation des premiers signaux (supportant la détection rapide évaluée en SAB) (Article 4).En outre, la segmentation manuelle d'images IRM du lobe temporal interne (premières régions cérébrales touchées dans la MA, et clées pour la MRV) a été appliquée à la problématique connexe de l'effet de l'âge au début de la MA (Article 5).Indépendamment, ces méthodes ont permis de mieux comprendre la MRV et son atteinte au début de la MA ; leur combinaison s'annonce très prometteuse. / Visual recognition memory (VRM) is impaired early in Alzheimer's Disease (AD), but would rely on two processes : familiarity (mere feeling that an item has been seen previously) and recollection (retrieval of details associated to the item at encoding). If recollection is clearly impaired in early AD, results concerning familiarity remain contradictory. Supposed to be faster than recollection, familiarity should be better understood using a temporal approach. Its possible impairment in AD could then be better understood.In order to test this, a behavioural procedure was designed: the SAB (Speed and Accuracy Boosting). Revealing different properties of VRM (its speed-limit, Articles 1 and 2; its « bottom-up » nature, Article 3) and some of its processes (familiarity appeares indeed faster than recollection, Article 1), results showed that the SAB procedure was mainly assessing familiarity (Article 1). In patients at risk of AD, an unexpected dissociation within familiarity processes was evidenced, with an impairment of late signals of familiarity (as used for classical judgements), but a preservation of the first signals (supporting fast detection assessed with the SAB) (Article 4).Last, manual segmentation of MRI images of the medial temporal lobe (first cerebral regions affected in AD, known for their key role in VRM) was also used to assess age effect at the early stage of AD (Article 5).Independently, both methods allowed understanding better the VRM and its impairment in early AD; their combination appears very promising.

From its empirical perspective, it was developed as a case study related to São Paulo city Zona Leste, considering its urging need for the conception of physical environments directed to the evocation and storage of memory. Our empirical targets were, therefore, the Centro de Comunicação e Educação Popular de São Miguel Paulista and the Centro de Memória e Cultura da Zona Leste. It was launched the following research inquiring: to what extend is there a relation between the recollection maintenance in spaces dedicated to memory and the process of building up individual and colective memory? Our hypothesis establishes that architectural and cultural heritages are impacted by the media influence in relation to their conception as communicative vehicles necessary to the evocation and storage of memory as well as towards the construction of memory communicative links based on a defined community experiences. Our general objective in this research is to understand how the effort to interchange memory to physical spaces deals with communication in its interactive and media dimensions, whereas its specific aims are: the establishement of considerations about communication and media environments developed in order to past portrayal; and the understanding between recollection and memory. This qualitative research is, therefore, based on study cases and field research, both using documental and bibliographical sources, as well as evidentiary method. Its theoretical basis about memory are found in the works of Jeudy (1990), Benjamin (1994), Bergson (1999) Huyssen (2000), Halbwachs (2004), Rossi (2010) and Dosse (2013). Concerning the distinctions between memory and recolletion, we make use of Lazzarato´s (2006), Tarde´s (2007) and Didi-Huberman´s (2013) studies. We also add to our considerations related to heritage concept the debates proposed by Meneses (1998), Harvey (2000), Ferrara (2002) and so. Concerning the debates about mediatization, interactions, fictionalization and identity, there are, respectively, the works of Braga (2008); Braga (2012); Augé (1998) and Bhabha (2013). In such authors we look for their understanding of memory using a critical perspective, as an object made invisible by historiography, and, therefore, the remains, the nighmares, the ghosts, the residual images, the silence / Este estudo teve como objeto de pesquisa epistemológico a dimensão comunicacional da memória. Já a investigação empírica tomou como estudo de caso a Zona Leste do município de São Paulo e sua necessidade preeminente de conceber espaços físicos destinados à evocação e ao armazenamento da memória. Como exemplares do objeto empírico, definiu-se o Centro de Comunicação e Educação Popular de São Miguel Paulista e o Centro de Memória e Cultura da Zona Leste. Lançamos o seguinte problema de pesquisa: Qual a relação comunicativa existente entre a manutenção da lembrança presente em espaços físicos dedicados à memória e o processo de construção da memória individual e coletiva? Nossa hipótese supõe que os patrimônios culturais arquitetônicos são impactados pelo aspecto midiático no que tange à sua concepção como veículos comunicativos necessários à evocação e ao armazenamento da memória e à construção dos vínculos comunicativos da memória a partir das vivências de uma comunidade. O objetivo geral desta pesquisa foi compreender como o esforço de transmutação da memória para espaços físicos lida com a comunicação em sua dimensão interativa e midiática. Já os específicos foram: estabelecer reflexões sobre a comunicação e os ambientes midiáticos criados para as representações do passado; compreender a relação entre lembrança e memória. Além dos métodos de estudo de caso, pesquisa de campo, documental e bibliográfico, este trabalho qualitativo contemplou o método indiciário. Basicamente, o amparo teórico sobre memória advém de Jeudy (1990), Benjamin (1994), Bergson (1999) Huyssen (2000), Halbwachs (2004), Rossi (2010) e Dosse (2013). Sobre a distinção entre as concepções de memória e lembrança, destacam-se Lazzarato (2006), Tarde (2007) e Didi-Huberman (2013). Às reflexões referentes aos conceitos de patrimônios, integram-se ao debate: Meneses (1998), Harvey (2000), Ferrara (2002) etc. Sobre midiatização; interação; ficcionalização e identidade somam-se, respectivamente, Braga (2008); Braga (2012); Augé (1998) e Bhabha (2013). Tais autores se relacionam na medida em que entendem memória numa perspectiva crítica, como aquilo que foi tornado invisível pela historiografia, portanto, os vestígios, os pesadelos, os fantasmas, as imagens sobreviventes, o silêncio
