Résumé du colloque

Memory problems are a major source of concern among aging and dementia. Whatever, different studies have shown a clear distinction between the pattern of spared and impaired memory’s functions observed in these subjects. None of them have focussed on the findings for prose materials, though text recall is a classic and frequent evaluation resource used, because is high sensibility to memory impairment and ecological value. Objectives : To compare processing and texts recall in normal aging, Mild Cognitive Impairment, Alzheimer and Parkinson’s diseases. This study, also, used a dual-task procedure in order to access texts processing, because the nature of the text materials has an important implication in prose recall. Methods : The materials selected in the past did not integrate psycho-linguistic data, so we have construct texts defined according to already existing models in cognitive psychology information processing. These texts varying in length and structure or genre. So, we provide four texts (description and narration texts) with a similarly constructed microstructure. In addition, the material we used for cued recall and recognition was rigorously controlled. Results : Qualitative and quantitative analyses we undertook show there are obvious functional and/or procedural differences in the nature of the processing devices involved. This will enable the pratician to either explain and determine some kind of behavior according to the " specific elements " affected, or analyze deficits, so as to provide a differential diagnosis.
