The
Effects of Spaced Repetition on Explicit and Implicit Memory
N. Kitao & T. Inoue |
Undergraduate
students studied stimulus words (nouns) which were presented successively
under three conditions; (1) spaced repetition, (2) massed repetition,
and (3) single presentation. Immediately after the study task, they
were given either an explicit memory test (free recall) or an implicit
memory test. In Experiment 1, 5 male and 57 female students were
given a word-fragment completion task as an implicit memory test.
The results showed significant spacing effects on implicit memory
as well as on explicit memory. In Experiment 2, 38 female students
were given a lexical decision task as an implicit memory test. The
results showed significant spacing effects on explicit memory but
not on implicit memory. These results were interpreted as an evidence
that spacing effects on implicit memory tests reflect conceptually-driven
processing. Key words: spacing effect, implicit memory, explicit memory |
