Two experiments investigated the effects of emotional stimuli on recollective experience in recognition memory. In Experiment 1, words judged to evoke a positive emotional response (e.g., warmth, freedom) or a negative emotional response (e.g., mucus, corpse) were associated with more “remember” responses than emotionally neutral words (e.g., crate, border) when presented in mixed lists. This effect was stronger with negative words than with positive words. In Experiment 2 the effects of emotional stimuli were eliminated when participants studied pure lists of either all emotional or all neutral words. These findings are discussed in relation to Rajaram's (1996) distinctiveness account of recollective experience.
