THERE ARE TWO MAIN TYPES OF REHEARSAL: MAINTENANCE REHEARSAL AND ELABORATIVE REHEARSAL.

Maintenance rehearsal=Involves repeating the information being remember over and over again to retain in STM. maintenance rehearsal can either be verbal (words),sub-v ocally(silently repeating the information if your head), or non-verbal(involving visual or spatial information).
