Ay. Wang et al., LONG-TERM RETENTION UNDER CONDITIONS OF INTENTIONAL LEARNING AND THE KEYWORD MNEMONIC, Bulletin of the Psychonomic Society, 31(6), 1993, pp. 545-547
This study was designed to assess long-term retention following either
keyword learning or rote rehearsal under conditions of intentional le
arning. A 2 condition (keyword vs. rote rehearsal) x time (immediate v
s. delay) completely randomized design was used, with 24 Tagalog langu
age nouns serving as the learning material. All subjects had uniformly
high levels of retention on the immediate test of cued recall. Howeve
r, on the delayed test of cued recall (2 days later), keyword learners
had forgotten almost twice the number of items as had subjects who ha
d rehearsed the same material by rote. Long-term forgetting was also g
reater for the keyword condition than for rote rehearsal when subjects
were assessed by a test of associative matching. This pattern of resu
lts replicates earlier research that has revealed a detrimental long-t
erm effect of the keyword mnemonic under conditions of incidental lear
ning.
