Dear Tipsters, It is my understanding from the memory literature that there are two ways in which information can be sent from STM to LTM. One is rote rehearsal or maintenance rehearsal, in which information is simply repeated, and the other is elaborative rehearsal, in which the information is processed more "deeply" (in line with Craik and Lockhart's idea). The latter is better.
Two cautions: 1. Craik and Lockhart actually challenged the STM/LTM model, preferring to speak about levels of processing. However, we can see a strong similarity between elaborative rehearsal in the standard model and their idea of depth or level of processing of the material. 2. The Peterson and Peterson study has nothing to do with LTM. In that study, participants were prevented from rehearsing during the recall interval and PP found that recall declined over a period of 18 sec. They concluded that STM lasts about this length of time if no rehearsal occurs. Note, however, that this conclusion has been challenged for a number of reasons, one of which is that counting backwards during the interval may have prevented rehearsal but it may also have interfered with the memory trace.
