Métamémoire et dysfonctionnement exécutif : Etude clinique des niveaux de perturbation et réflexion sur les méthodes d'investigation de la métamémoire

Abstract : The aim of this work was double. On the one hand, it had as an aiming to realise a clinical study of the different levels of disturbances of the metamemory among frontal dysexecutive patients as well as links between metamemory processes and executive functions. In addition, we discussed methods to investigate the metamemory in these patients. We had therefore first presented a review on metacognition, metamemory and the links between metamemory and the executive functions. Experimentations were set up on 2 parts : 2 experiments focussed on making an exhaustive evaluation of the different components of metamemory and of executive functions in focal frontal and dysexecutive patients and 2 studies focussed on methodological aspects. Both experiments 1 and 2 highlighted a selected effect on some metamemory processes and links between these processes and some specific executive functions, for example abilities on planning and measures of metamemory monitoring. The third experiment was focused on the influence of study time allocation on other metamemory processes : contrary to control subjects, patients less benefit from self-paced study time. The last experiment was led in order to consider different difficulties regarding the methods used in order to evaluate the various paradigms, and more particularly the FOK judgment paradigm. All the collected data have been examined, and they converge to support the idea that metamemory was not a unitary function but constituted of several distinct processes. Data also showed that metamemory will be selectively disturbed in frontal and/or dysexecutive brain-damaged patients.
