Age Differences in Autobiographical Memory Specificity: It’s Not Just About Cognition
Lisa Emery & Meagan Griffin
INTRODUCTION
RESULTS
Previous research has found that older adults have
reduced specificity of autobiographical memory, a finding
that has primarily been attributed to age differences in
associative memory and/or executive function (e.g.,
Addis, Wong, & Schacter, 2008; Piolino et al. 2010).
Research in the clinical psychology literature, however,
suggests that reduced autobiographical memory
specificity can also result from emotion regulation
strategies such as functional avoidance (Williams et al.,
2007). Because older adults are thought to avoid retrieval
of negative memories (e.g., Mather & Carstensen, 2005),
we investigated whether age differences in emotion
regulation strategies also influenced memory specificity.

• Age differences in autobiographical memory specificity
were influenced by both associative memory and use
of active coping strategies. These effects were
independent of each other, and together accounted
for nearly all the age-related variance in specificity.
• There were no age differences in avoidant coping, and
contrary to the functional avoidance hypothesis,
avoidant coping did not influence memory specificity.
• Overall, this suggests that age differences in affective
processes combine with age differences in cognitive
processes to influence autobiographical memory
retrieval.

Participants
• 28 young adults (Ages 18-25; M = 19.3, SD = 1.7)
• 29 older adults (Ages 64-85; M = 73.3, SD = 7.1)
• Data collected as part of another study (see poster
by Burkett et al.)
• Participants were screened for cognitive problems
using the Short Blessed
• Specificity coding was not yet available for all
participants
Measures
• Cue-word autobiographical memory test; responses
coded for specificity on a scale of 0-3
• WAIS-IV matrix reasoning
• WMS-IV verbal paired associates
• Modified version of the COPE (Carver et al., 1989)
• Active coping questions
“I take additional action to try to get rid of the
problem”
• Avoidant coping questions (combo. of
mental avoidance, behavioral avoidance,
and denial)
“I pretend that it hasn’t really happened”

• Why does active coping result in reduced memory
specificity? (e.g., perhaps focusing attention on solving
the problem instead of dwelling on memory of it).
• Avoidant coping questions from COPE don’t quite
capture “functional avoidance” as defined by Williams
et al. (2007). (e.g., “Truncated search” of memory to
avoid negative affect from recall of unpleasant events)
