A Study to Remember:
The Effect of Depth of Processing and Rehearsal on
Immediate and Delayed Recall
Paulene Meyers, RHS Ô06
The purpose of the current study was to determine the effect of depth of
processing and rehearsal on immediate and delayed recall of vocabulary. It was
hypothesized that for both immediate and delayed recall, deeper processing
techniques would produce better results than a shallow processing technique
(flashcards), and that self-reference would be more effective than
other-reference. It was also hypothesized that rehearsal would improve
immediate and delayed recall. One hundred and seventy-three eighth grade
students were assigned to a rehearsal and processing condition. Students were
given 16 words to learn using their assigned methodology and were tested
immediately and one day after. A repeated measures ANOVA demonstrated that
immediate recall scores were higher than delayed recall scores (p<.05). A
significant interaction was found between test and processing level (p<.001).
On the immediate recall quiz, students in the self-reference condition
performed best, and students in the shallow processing condition performed
worst. However, on the delayed recall quiz, the three groupsÕ scores were
statistically equivalent. Surprisingly, rehearsal had no significant impact on
studentsÕ performance on either test.
