• It is an important control process of STM.
• It is used to retain the information for as much time as required.
• As the name suggests these kinds of rehearsals simply maintain information through repetition and when such repetitions discontinue the information is lost.
• It is carried through silent or vocal repetition.
Elaborative rehearsals:
• From the STM information enters the long term memory through elaborative rehearsals.
• This rehearsal attempts to connect the “to be retained information” to the already existing information in long term memory.
e.g. the task of remembering the meaning of the work “humanity” will be easier if the meaning of concepts such as “compassion”, “truth” and “benevolence” are already in place.
• In elaborate rehearsals, one attempts to analyse the information in terms of various information it arouses.
• Assignment of meaning and associations are formed. –
• It involves organization of the incoming information in as many ways as possible e.g. we can expand the information in some kind of logical framework, link it to similar memories or else create a mental image.
