Highly affective memories have been thought to be longer lasting and more
detailed than other memories, and many experimental results have supported this
assertion. The apparent robustness of these memories, however, may result from their
high distinctiveness, rather than their emotional content. Two experiments tested free
and cued recall for negative affect, distinctive, and neutral paragraphs. Experiment 1
compared neutral and negative affect paragraphs using a blocked and recovered memory
technique.
Affective paragraphs were remembered significantly better than neutral
paragraphs in free recall of paragraph titles, regardless of condition. Details of neutral
paragraphs were remembered significantly better than affective paragraphs, regardless of
condition. No recovery effect was found.
Experiment 2 compared distinctive and neutral paragraphs using the same
technique. Free recall of paragraph titles did not differ between paragraph types. Neutral
paragraphs were remembered better than distinctive paragraphs in cued recall, regardless
of condition. Participants remembered significantly more with cued recall, and significantly more in the forget condition, and distinctive paragraphs were subject to a
much greater forgetting effect than neutral paragraphs. It is unclear why a robust
forgetting effect, using these stimuli, was not found. Consistent with previous literature,
affective stimuli were remembered well, but inconsistently, distinctive stimuli were not.
These results provide support for the claim that negative affect memories are more
robust than other memories. This may result from their inherent emotional content as
opposed to their being distinctive in some way.
