In a classic memory study by Peterson and Peterson (1959),participants were given consonant strings to remember-such as DBX and HLM-and then were instructed to count backward from 100 by 3.After a variable amount of time (delay),the participants were asked to recall the consonant strings.Which statement accurately describes the results of the experiment?
A)There was no decrease in recall accuracy until the delay reached about 20 seconds.
B)A 3-second delay decreased accuracy by almost 80%.
C)A 20-second delay decreased accuracy by over 80%.
D)There was no decrease in recall accuracy until the delay reached about 7 seconds.

Quizplus · Accepted Answer

The results of the experiment showed that there was no decrease in recall accuracy until the delay reached about 20 seconds. After a 20-second delay, accuracy decreased by over 80%. Option A is incorrect because there was a decrease in recall accuracy after a 20-second delay. Option B is incorrect because a 3-second delay did not decrease accuracy by almost 80%. Option D is incorrect because there was a decrease in recall accuracy before the delay reached 7 seconds.
