2.8 Intelligence and Achievement question 1
[Maximum number: 1]
A researcher compared the effectiveness of massed versus distributed practice in preparing for a memory test.
Each of two groups memorized the definitions of 40 vocabulary words.
In group A, there were 30 participants who were all under twenty-five years of age. Participants in group A used
the method of distributed practice, studying for 30 minutes on each of four evenings. They were tested on the
fifth morning at 7:00 A.M. In group B, there were 30 participants who were all over sixty years of age.
Participants in group B used the method of massed practice, studying only from 6:30 P.M. to 8:30 P.M. on the
evening before the test. They were tested the next morning at 7:00 A.M.
All participants completed a recall test. The test measured how quickly participants recalled the definitions. The
results showed that the mean difference between the distributed practice group and the massed practice group
was statistically significant. The researcher provided a list of the names and test scores for each individual
participant in a letter to all participants.
