Schematic overview of the VR training program used in the OctaVis. A) During the first three days, healthy participants had to memorize and buy items of a target shopping list (list A), which was auditorily presented at the beginning of the trials. On day four, a new, interfering list (list B) was presented and participants had to memorize and buy only items of this interference list. On day five, participants had to recall and buy only items of the target list A, but without any further presentation and learning of list A. B) For the epilepsy patients, an extended program was used. This included six days of learning, on which the patients had to memorize and buy items of an auditorily presented target list (list A). On day 7, a new, interfering list (list B) was presented and participants had to memorize and buy only items of this interference list. On day 8, participants had to recall and buy only items of the target list A, but without any further presentation and learning of list A.
