Author information

The authors investigated retrospective timing in participants with Korsakoff's syndrome. Patients were assessed on four retrospective tasks on which they were instructed to read three-digit numbers aloud (15 seconds), fill connected squares (30 seconds), decide whether words were abstract or concrete (45 seconds), or read aloud a text about mushroom picking (60 seconds). Participants were not aware of the task's timing until the end of the tasks, when they were asked to estimate the elapsed time. Results revealed an underestimation of the elapsed time in Korsakoff participants, suggesting that time is perceived to pass quickly for these participants.
