Résumé
Background: Visual perspective during memory retrieval has mainly been evaluated withmethodologies based on introspection and subjective reports. The current study investigateswhether visual perspective can be evaluated with a physiological measurement: pupil dilation.Methods: While their pupil diameter was measured with an eye-tracker, forty-five participantsretrieved one memory from a field perspective (i.e., as viewed through our own eyes) and onememory from an observer perspective (i.e., as viewed from a spectator’s standpoint). Afterretrieval, participants rated the emotional intensity of the memories.Results: Analysis demonstrated larger pupils during the retrieval of memories from a fieldperspective and higher emotional intensity for memories retrieved from a field perspective.Discussion: The larger pupils for memories recalled from a field perspective could, however, notbe attributed to their higher emotional intensity. These findings suggest that pupil dilation couldbe used as a physiological assessment of visual perspective during memory retrieval
