How Stereotypes Can Threaten Your Driving

In 1995, Stanford University psychologists Claude Steele and Joshua Aronson completed a series of ground breaking experiments showing that evoking negative stereotypes about a group can actually undermine the performance of people in that group — a phenomenon known as stereotype threat.

Steele and Aronson’s research demonstrated that stereotype threat. Similarly, new research published in Applied Cognitive Psychology shows that negative stereotypes about older drivers may hinder their performance behind the wheel.

Older drivers are often portrayed negatively in popular media and in the news as less safe and competent than their younger counterparts. However, research actually shows that drivers 65 and older are among the safest drivers on the road. For example, the Insurance Institute for Traffic Safety finds that seniors are far less likely than younger drivers to engage in dangerous activities, such as drunk driving or texting, behind the wheel.

A team of psychological scientists led by Ann Lambert of the University of Utah wanted to know whether exposure to negative age-related stereotypes could have the unintended effect of harming older people’s driving performance.

Lambert and colleagues suspected that stereotype threat interferes with performance by competing for cognitive resources related to working memory capacity (WMC) — the ability to maintain task goals in mind in the face of distraction. That is, when people feel anxious and stressed about their performance, they may have fewer cognitive resources available for other processes. When it comes to driving, this means that people who are anxiously self-monitoring their performance may have less working memory capacity available for the processes necessary for safe driving.

For the study, 39 volunteers ranging in age from 62 to 83 years old came to the University of Utah campus to take part in a driving simulator study. Twenty participants were male and 19 were female.

Working memory capacity was assessed by asking each participant to complete a very challenging memory task. Participants had to attempt to solve an equation and then memorize a word. At the end of each set of problems, they were asked to recall words in the correct serial order. All participants met a minimum math accuracy criterion of 80%.

Next, participants were randomly assigned to the stereotype threat or the control condition. Both conditions were identical except that in the stereotype threat condition, participants heard the following script:
“Before we begin collecting driving data, I want to tell you a little more about the purpose of this study. Older adults, as a group, are stereotyped to be bad drivers. While it may be the case that not all older adults are bad drivers, there is some evidence that this stereotype may be true. Here are some examples of evidence that older adults may be bad drivers.”

During the experimental drive, participants were instructed to follow a lead vehicle at a specific safe distance, braking whenever this lead vehicle braked, and to exit at the city of Murray, which required a lane change.

As predicted, evoking stereotype threat resulted in significant driving impairments in drivers already low in working memory capacity. Their driving showed the same pattern of distraction that is typical of people attempting to talk on the phone while driving: They had slower reaction times on the brakes and had difficulty maintaining the correct following distance compared to the control group.

Ultimately, the researchers explain, the local laws and policies designed to increase awareness of the challenges of driving and aging may be undermining seniors’ safety.

“Our findings present an urgent safety concern,” the Lambert and colleagues write. “Ironically, the re-evaluation process and even the media coverage of these policies may unintentionally elicit stereotype threat effects in driving, akin to those reported here, ultimately jeopardizing public safety.”
