B)Presenting the stimulus list at a slower pace

D)Using a very long list (greater than 30 items at one item per second)

Question

Counting backward for 30 seconds before recall will disrupt rehearsal of the recent items, preventing them from being transferred to long-term memory and causing the recency effect to disappear. Delaying recall or presenting the stimulus list at a slower pace may also decrease the primacy effect by interfering with the encoding of the early items, but they are less likely to affect the recency effect. Using a very long list may also reduce the recency effect, but it is not a reliable method because it may overload working memory and cause confusion. Therefore, the best choice is C, counting backward for 30 seconds before recall.
