While it's not necessarily true that you're only as old as you feel, you may be only as old as you think:
In a paper appearing in the current issue of the journal Social Cognition, psychologists report that men and women in late middle age underperformed on a standard memory test when told they were part of a study including people over age 70.
Inclusion with an older group — an indirect reminder of the link between age and memory slippage — was enough to affect their scores, especially for those who were most concerned about getting older, the authors concluded.
Researchers refer to this self-undermining as a stereotype effect, and they have documented it in many groups. In studies, women perform less well on math exams after reading that men tend to perform better on them. Similarly, white men perform less well when they are told that they are competing in math against Asian students.
People over 65 also slump on memory tests when they are reminded of the link between age and mental decline. The new study, financed by the National Institute on Aging, is the first to show the effect so clearly in a borderline group, experts say — middle age is certainly not young, but it is well short of “senior.”
