But there are actually two types of rehearsal: rote or maintenance rehearsal
and elaborative rehearsal.
What researchers call maintenance rehearsal
involves repeating the information mentally without regard to its meaning 6 for example, going through a grocery list and remembering the items just as words without regard to the meal they will become.
Woodward, Bjork, and Jongeward (1973) further added that participants engage in maintenance rehearsal of items until an instruction is given.
In support of this view, Greene (1987), in a review of the literature, found that increasing maintenance rehearsal (sometimes reported as rote rehearsal) increases performance on recognition tests, but not recall tests.
However, earlier work by Smyth did produce evidence of more specific visuospatial interference during maintenance rehearsal. Smyth & Pendleton (1990 observed that recall of a sequence of five Corsi block positions was poorer after subjects had watched the experimenter point to a further five positions during an interpolated interval, although this effect was restricted to order rather than item memory.
Consequently, it is not possible to determine whether the visual interference with the pegword mnemonic was limited to encoding and recall, or whether such interference extended also to maintenance rehearsal. Quinn (1988) did separate out encoding and maintenance phases of the Brooks spatial task, and noted that interference from the brightness judgement task was confined to the encoding phase.
In Hershey, the cast had "maintenance rehearsals
'' to make sure everything was in step.
