Abstract

To examine the relationship between visual imagery and autobiographical memory, eye positionand pupil size were recorded while participants first searched for memories and then reconstructedthe retrieved memories (Experiment 1), or only searched for memories (Experiment 2).In Experiment 1, we observed that, although recollective experience was not associated with thenumber of fixations per minute, memories that took longer to retrieve were linked to increasedpupil size. In Experiment 2, we observed that directly retrieved memories were recalled morequickly and were accompanied by smaller pupils than generatively retrieved memories. Aftercorrecting for response time, retrieval mode also produced an effect, showing that decreased pupilsize is not simply due to directly retrieved memories being recalled more quickly. These findingsprovide compelling evidence that objective measures, such as pupil size, can be used alongsidesubjective measures, such as self-reports, to distinguish between directly retrieved and generativelyretrieved memories.
