... preventing rehearsal of information to be recalled, suggests the importance of rehearsal as the active process. Word length effect, where it was found that recall was poorer with longer words and later shown that this was because subvocal rehearsal is in real time, so rehearsal time was decreased, again indicates the importance of rehearsal for maintaining phonological information in short-term memory. The phonological similarity effect, whereby similar sounding words produced poorer recall than distinct words, suggests the fading of words stored in the phonological loop and the confusion with similar information. Overall, findings suggest because the effects rest on similar common processes, they should interact in predictable ways. The interaction of these effects show rehearsal to be the active process supporting the phonological store and that these two systems make up the phonological loop. The importance of the phonological loop, and therefore rehearsal, in the encoding of new memories is ...
