The present study revealed that older adults recruit cognitive control processes to strengthen positive and diminish negative information in memory. In Experiment 1, older adults engaged in more elaborative processing when retrieving positive memories than they did when retrieving negative memories. In Experiment 2, older adults who did well on tasks involving cognitive control were more likely than those doing poorly to favor positive pictures in memory. In Experiment 3, older adults who were distracted during memory encoding no longer favored positive over negative pictures in their later recall, revealing that older adults use cognitive resources to implement emotional goals during encoding. In contrast, younger adults showed no signs of using cognitive control to make their memories more positive, indicating that, for them, emotion regulation goals are not chronically activated.
Previous findings reveal that older adults favor positive over negative stimuli in both memory and attention (for a review, see Mather & Carstensen, 2005). This study used eye tracking to investigate the role of cognitive control in older adults' selective visual attention. Younger and older adults viewed emotional-neutral and emotional-emotional pairs of faces and pictures while their gaze patterns were recorded under full or divided attention conditions. Replicating previous eye-tracking findings, older adults allocated less of their visual attention to negative stimuli in negative-neutral stimulus pairings in the full attention condition than younger adults did. However, as predicted by a cognitive-control-based account of the positivity effect in older adults' information processing tendencies (Mather & Knight, 2005), older adults' tendency to avoid negative stimuli was reversed in the divided attention condition. Compared with younger adults, older adults' limited attentional resources were more likely to be drawn to negative stimuli when they were distracted. These findings indicate that emotional goals can have unintended consequences when cognitive control mechanisms are not fully available.
Previous studies have found that younger adults detect threatening stimuli more quickly than other types of stimuli. This study examined whether older adults also show this adaptive threat-detection advantage. On each trial in the experiment, participants saw an array consisting of nine schematic faces. Eight of the faces were neutral; the ninth was neutral, angry, happy, or sad. Participants indicated whether there was a discrepant face in each array. Both older and younger adults were significantly faster to correctly detect a discrepant face when it signaled threat than when it signaled happiness or sadness. There was no age difference in this threat-detection advantage, indicating that this automatic process is maintained among older adults.
A large body of work reveals that people remember emotionally arousing information better than neutral information. However, previous research reveals contradictory effects of emotional events on memory for neutral events that precede or follow them: in some studies emotionally arousing items impair memory for immediately preceding or following items and in others arousing items enhance memory for preceding items. By demonstrating both emotion-induced enhancement and impairment, Experiments 1 and 2 clarified the conditions under which these effects are likely to occur. The results suggest that emotion-induced enhancement is most likely to occur for neutral items that: (1) precede (and so are poised to predict the onset of) emotionally arousing items, (2) have high attentional weights at encoding, and (3) are tested after a delay period of a week rather than within the same experiment session. In contrast, emotion-induced impairment is most likely to occur for neutral items near the onset of emotional arousal that are overshadowed by highly activated competing items during encoding. Effects of emotional arousal on memory: Reconciling findings of emotioninduced enhancement and impairmentWhen stimuli evoke emotional arousal, that emotion affects not only memory for the emotional stimuli but also memory for stimuli appearing just before or after the emotional item. Indeed, many studies reveal impaired memory for stimuli preceding or following an emotional item in a list of items (Bornstein, Liebel, & Scarberry, 1998;Detterman, & Ellis, 1972;Ellis, Detterman, Runcie, & Craig, 1971;Erdelyi & Blumenthal, 1973;Hadley & MacKay, 2006;Hurlemann et al., 2005;MacKay et al., 2004;Miu, Heilman, Opre, & Miclea, 2005;Runcie & O'Bannon, 1977;Schmidt, 2002;Strange, Hurlemann, & Dolan, 2003). However, a recent study provides an intriguing puzzle in its apparent contradiction with previous findings. Anderson, Wais and Gabrieli (2006) found that merely appearing before an emotionally arousing picture enhanced memory for a neutral picture a week laterrather than impairing memory for it, as would be expected given the prior studies. In the experiments outlined here, we attempted to demonstrate both the enhancement and impairment effects within the same experimental paradigm, with the hope that by revealing what leads arousing items to impair memory for nearby items in one case but enhance memory for nearby items in another case, we would gain insight into the fundamental mechanisms of how emotional arousal modulates memory.
