Thinking your memory will get worse as you get older may actually be a self-fulfilling prophecy. Researchers at North Carolina State University have found that senior citizens who think older people should perform poorly on tests of memory actually score much worse than seniors who do not buy in to negative stereotypes about aging and memory loss.
In a study published earlier this month, psychology professor Dr. Tom Hess and a team of researchers from NC State show that older adults’ ability to remember suffers when negative stereotypes are “activated” in a given situation. “For example, older adults will perform more poorly on a memory test if they are told that older folks do poorly on that particular type of memory test,” Hess says. Memory also suffers if senior citizens believe they are being “stigmatized,” meaning that others are looking down on them because of their age.
“Such situations may be a part of older adults’ everyday experience,” Hess says, “such as being concerned about what others think of them at work having a negative effect on their performance – and thus potentially reinforcing the negative stereotypes.” However, Hess adds, “The positive flip side of this is that those who do not feel stigmatized, or those in situations where more positive views of aging are activated, exhibit significantly higher levels of memory performance.” In other words, if you are confident that aging will not ravage your memory, you are more likely to perform well on memory-related tasks.
The study also found a couple of factors that influenced the extent to which negative stereotypes influence older adults. For example, the researchers found that adults between the ages of 60 and 70 suffered more when these negative stereotypes were activated than seniors who were between the ages of 71 and 82. However, the 71-82 age group performed worse when they felt stigmatized.
Finally, the study found that negative effects were strongest for those older adults with the highest levels of education. “We interpret this as being consistent with the idea that those who value their ability to remember things most are the most likely to be sensitive to the negative implications of stereotypes, and thus are most likely to exhibit the problems associated with the stereotype.”
“The take-home message,” Hess says, “is that social factors may have a negative effect on older adults’ memory performance.”

Abstract: Recent research has suggested that negative stereotypes about aging may have a detrimental influence on older adults’ memory performance. This study sought to determine whether stereotype-based influences were moderated by age, education, and concerns about being stigmatized. Possible mechanisms underlying these influences on memory performance were also explored. The memory performance of adults aged 60 to 70 years and 71 to 82 years was examined under conditions designed to induce or eliminate stereotype threat. Threat was found to have a greater impact on performance in the young-old than in the old-old group, whereas the opposite was observed for the effects of stigma consciousness. In both cases, the effects were strongest for those with higher levels of education. Further analyses found little evidence in support of the mediating roles of affective responses or working memory. The only evidence of mediation was found with respect to recall predictions, suggesting a motivational basis of threat effects on performance. These findings highlight the specificity of stereotype threat effects in later adulthood as well as possible mechanisms underlying such effects.
