Question 1 Report
Which of the following methods would best test the duration of short-term memory? A researcher gives volunteers an unfamiliar three-letter code, prevents rehearsal by asking them to count backwards, and changes the delay before recall.
(a) Name the dependent variable in this study. [1]
(b) Outline why counting backwards is included. [2]
(a) Number of codes/letters correctly recalled / recall score [1] (b) It prevents participants rehearsing the code [1], so the researcher is more likely to measure the duration of STM rather than rehearsal effects [1]
