Mémoire épisodique et composante associative : nouvel outil d'évaluation en modalité visuelle

Abstract : Introduction : Episodic memory concerns events personally experienced and situated in their spatio-temporal context of acquisition ; it is impaired in normal aging. An episodic memory is constructed through binding, which links contextual features of an event into a common episode.
Objective : Current assessment tools of EM are mainly in verbal modality. An impairment of semantic memory can therefore impact the results. Moreover, they do not evaluate EM in its whole complexity (binding not studied). To limit these biases, we propose a new assessment tool (AppartMem) in visual modality. Self-reference is also studied.
Method : 60 participants (18-35 and 65-80 years old) took the AppartMem test, based on the RL-RI 16 model with free and cued reminding tests. Neuropsychological tests were also proposed.
Results : Our tool is sensitive to age effect on the items. We observed an age and cueing effect on the recall of associative items for older participants. Self-reference does not seem to predict recall, nor do the different cognitive functions assessed.
Conclusion : Our tool is sensitive to age and normal ME impairment. The binding is also influenced by the age. However, the recall conditions will be modified so that the tool assess episodic memory in visual modality only. Other biases will be taken into account.
