L’objectif de ces travaux de thèse était d’avancer dans la connaissance des effets du vieillissement normal sur les capacités d’attention soutenue et les mécanismes de contrôle attentionnel qui les sous-tendent. A cette fin, nous avons combiné l’utilisation de mesures comportementales, subjectives, et électrophysiologiques (potentiels évoqués). Les résultats comportementaux mettent en évidence des effets différenciés de l’âge sur les capacités d’attention soutenue en fonction de l’approche utilisée : détérioration dans les tâches de détection, et préservation dans les tâches d’inhibition. Les données électrophysiologiques mettent en évidence plusieurs spécificités des seniors dans l’engagement des mécanismes de contrôle attentionnel en situ...
