Abstract
Memory impairment is prevalent in multiple sclerosis (MS). Retrieval practice is a powerful memory technique whereby retrieving information (quizzing oneself) leads to better memory than restudying. In a within-subjects experiment, 12 memory-impaired MS patients encoded verbal paired associates (VPAs) through massed restudy (MR), spaced restudy (SR), or retrieval practice (RP). Half of VPAs were tested after short delay (30 minutes) and half after long delay (one week). RP robustly improved memory more than restudy. Short delay: MR=15.6%, SR=27.1%, RP=72.9%. Long delay: MR=1.0%, SR=4.2%, RP=24.0%. RP was the best memory technique for nearly all patients after both short and long delays.
