Emotional Memory and Aging
Emotion researchers have discovered that as people get older, they experience fewer negative emotions and report better control over their emotions. (For more information about research on emotional experience and aging, you may be interested in visiting Laura Carstensen's lab webpage.)
One line of research in our lab investigates whether strategic processes in older adults' emotional attention and memory play a role in this improved emotional well-being with age.
We have found that older adults show more emotionally gratifying memory distortion for past choices and autobiographical information than younger adults do (Mather & Johnson, 2000; Kennedy, Mather, & Carstensen, 2004). In addition, when shown stimuli that varies in affective valence, positive items account for a larger proportion of older adults' subsequent memories than in younger adults (e.g., Charles, Mather, & Carstensen, 2003; Mather & Knight, 2005; Mather, Knight, & McCaffrey, 2005).
This positivity effect in older adults' memories seems to be due to their greater focus on emotion regulation and to be implemented by cognitive control mechanisms that enhance positive and diminish negative information.
For instance, when participants are simply asked to watch a slide show of pictures and later to recall the pictures (see Mather & Knight, 2005), older adults show a positivity effect when compared with younger adults:
In contrast, when participants are distracted because they must do a concurrent task while watching the picture show, most of what older adults recall consists of negative information:
These findings indicate that older adults use cognitive resources to help direct their attention and memory encoding processes towards information that will help them regulate their emotions.
In a couple of papers (Mather, in press; Mather & Carstensen, 2005), we have proposed that age differences in the valence of emotional memory will be seen when cognitive control processes are likely to influence the memory process, but not when the nature of the emotional influence is more automatic (e.g., Mather & Knight, 2006, threat detection summary).
