Sleep and Rehearsal-Driven Memory in Epilepsy

"Encoding: (1) Participants will learn 60 associations between pairs of items (cue and target) that are presented sequentially at unique locations on a screen, in a given context. 30 pairs are presented once, and 30 pairs are presented repeatedly (4 times).~(2) After learning, the first recall phase begins after a short delay of 30 minutes: 50% of the pairs are tested in a similar way, this time with an assessment of contextual memory.~(3) The remaining 50% of pairs are tested after a 12-hour delay, involving either a day awake (condition 1) or a night asleep (condition 2)."

Eye-tracking will be carried out during the task to ensure that participants are focused on the task (quantification of the number and duration of eye fixations in the area of interest corresponding to the target presentation)

Questionnaire on task-related fatigue (Likert-scale) will be completed by participants between blocks of items during the task

Questionnaires on task difficulty (Likert-scale) will be completed by participants at the end of the task

Participants' state of sleepiness will be assessed at the beginning of each stage (encoding, immediate recall, delayed recall) using the Karolinska sleepiness scale
