Analyzing Past Failures Helps Boosts Performance on New Tasks

Analyzing past failures may boost future performance by reducing stress, according to a new study.

Researchers report that writing critically about past setbacks leads to lower levels of the stress hormone cortisol, and more careful choices when faced with a new stressful task, resulting in improved performance.

The study, published in the open access journal Frontiers in Behavioral Neuroscience, is the first to demonstrate that writing and thinking deeply about a past failure improves the body’s response to stress and enhances performance on a new task.

This technique may be useful in improving performance in many areas, including therapeutic settings, education, and sports, researchers claim.

While people are often advised to “stay positive” when faced with a challenging task, past research suggests that paying close attention to negative events or feelings — by either meditating or writing about them — can actually lead to positive outcomes.

But why does this counter-intuitive approach lead to benefits?

To investigate this question, Brynne DiMenichi, a doctoral candidate from Rutgers University-Newark, together with other researchers from the University of Pennsylvania and Duke University, examined the effect of writing about past failures on future task performance in two groups of volunteers.

For the study, a test group wrote about their past failures while a control group wrote about a topic not related to themselves.

The researchers used salivary cortisol levels to provide a physiological readout of the stress experienced by the people in both groups. These levels were comparable across the test and control groups at the start of the study, the researchers report.

The researchers then measured the performance of the volunteers on a new stressful task and continued to monitor their cortisol levels. They found that the test group had lower cortisol levels compared to the control group when performing the new challenge.

“We didn’t find that writing itself had a direct relationship on the body’s stress responses,” said DiMenichi. “Instead, our results suggest that, in a future stressful situation, having previously written about a past failure causes the body’s stress response to look more similar to someone who isn’t exposed to stress at all.”

The researchers also found that volunteers who wrote about a past failure made more careful choices on a new task, and performed better overall than the control group.

“Together, these findings indicate that writing and thinking critically about a past failure can prepare an individual both physiologically and cognitively for new challenges,” DiMenichi said.

While everyone experiences setbacks and stress at some point in their lives, the study provides insight about how we can use these experiences to perform better in future challenges.

“It provides anyone who wants to utilize this technique in an educational, sports, or even therapeutic setting with clear-cut evidence of expressive writing’s effectiveness,” said DiMenichi. “However, it is difficult to compare laboratory measures of cognitive performance to performance on, say, the Olympic track. Future research can examine the effect of writing manipulation on actual athletic performance.”
