Remember when you were a
child and adults seemed to always be saying, "You are too young. Wait till
you get older." Or, they said, "You will understand this better when
you grow up." Now that you are older, especially if you are my age, people
seem to be saying in the politest way they can, "When are you planning to
retire?" "We have to make room for younger workers."
Oh, and if you are in the
job market, a young person is often told "I'm afraid you don't have enough
experience yet." But if you are over 50 or so, they will say "You are
over-qualified for this position."
These inevitable
put-downs are bad enough. But what you may not realize is that when you accept
such judgments of others, you may well impair your performance capability and development.
Here, I report research showing that this effect applies particularly to
seniors, and that the effect can be counteracted by the right kind of
intervention.
A study by Becca Levy (1)
showed that seniors can generate a positive self-stereotype that improves memory
performance. Moreover, the effect is more readily established if positive
priming is done implicitly, that is without conscious realization. In this
study they flashed positive-stereotype words on a screen at a rate fast enough
to be registered by the brain but below the level of consciousness. Prior
studies had shown that it is rather difficult to improve memory performance
with explicit priming, perhaps because such priming is superficial relative to
what might occur with implicit conditioning. This point is relevant here
because much of our age-stereotype processing, both in youth and older age, is subliminal.
While consciously we reject the age-related limitations that others imposed on
us, repeatedly experiencing the put-downs grinds away at our resistance by
unconscious, implicit means.
Here, a computer
subliminally presented 90 seniors with words related either to an old-age image
of senility or wisdom. Because all people vary a little in their speed
threshold for conscious perception of words on a screen (it takes about 125-250
msecs), the view time was adjusted to be just below threshold for each subject.
Before and after the priming intervention, three kinds of memory tests were
given: 1) working memory immediately after a test, 2) recall immediately after
repeat testing confirmed learning, and 3) recall after a delay in which other
tasks were performed.
The group that received subliminal
stimulation of positive stereotype words had better memory test scores, a
higher estimate of their memory capability, and a more positive outlook on
tests that measured attitude about aging. Declines were observed in the group
that received negative-stereotype word stimulation.
A second study tested
young people in the same way, and no such benefit of positive-stereotype
conditioning was evident. This may indicate that a person’s pre-existing
self-image governs how one responds to priming. Young people have not been
pre-conditioned to think their memory is weak because of age.
A related study showed
that a person’s explicit belief in their self-efficacy affects their memory
performance (2). Typically, as a person ages, the confidence in memory ability
declines. But this study aimed to raise confidence in memory ability in 84
people over 50 by a memory training program that integrated a memory skills
training class for six weeks, three hours per week, with elements designed to
change beliefs about memory competence. The study showed that by emphasizing
mastery, verbal encouragement, reduced anxiety, and modeling skills throughout
training, subjects became more convinced that they should believe in themselves
and their ability to learn how to be more effective learners. And the memory
tests bore out that prediction.
Recent studies by my
fellow faculty member at Texas A&M, Lisa Geraci and her collaborator,
showed that memory confidence can be easily bolstered in seniors and that, once
more confident, they perform better (3). Their review of older literature
established that negative stereotype priming can make seniors underperform. In
their study, young college students and older adults (70 years average) were
divided into equal groups that took a mental task that could be readily
completed, or was impossible to complete, or given no task. The task items were
clusters of five scrambled words that were to be re-arranged into a
comprehensible sentence. Neutral words were used that had no priming relevance
to age stereotyping. All subjects then took a free recall of a word list they
were allowed to study for two minutes. OIder subjects in the task-success group
recalled more words and reported less test-anxiety than those in the task-failure
group or in the no-task group. No such task effects were seen in the young
adults.
So, how can we apply
these findings to everyday life outside the laboratory? Obviously, we have to
contrive other ways to provide implicit positive priming. Maybe this could come
from making more of an effort to improve memory, as my book Memory Power 101 aims to do. When your
memory ability improves from using some established learning principles and
techniques, you implicitly know it and that would reinforce positive feelings
about memory capability. Indeed, this is what "memory athletes"
experience. As they practice memorizing, they get better at it, of course, and
this must surely have a subliminal effect on their sense of innate capability
which in turn helps them reach memory championship-level performance.
Each of these studies
makes the point that if you believe you can remember better, maybe you really
can, and that in turn promotes positive feelings about the ability to remember.
This becomes a self-perpetuating positive feedback loop for success. Learning capability improves, in large part
because of "learning-set" principles, which is a topic for another
day. But as these studies I just summarized show, there is a beneficial
component from a change in attitude about one's stereotype. So, for both
reasons, I emphasize with my students,
The more you know, the more you can know.
