How are maintenance rehearsals different from elaborative rehearsals?

Maintenance rehearsals: These kinds of rehearsals simply maintain information through repetition and when such repetitions discontinue the information is lost. They are carried through silent or vocal repetition.

Elaborative rehearsals: These rehearsals attempt to connect the ‘to be retained information’ to the already existing information in long-term memory. In elaborative rehearsals one attempts to analyse the information in terms of various associations it arouses. It involves organisation of the incoming information in as many ways as possible.
