Well, It’s Just Hopeless:”We slow down after mistakes, but still mess up”
It’s no secret that people slow down mentally after making a mistake. Monkeys do, too. …
“Our research reveals that a combination of changes in the brain slow us down after mistakes…One gathers more information for the decision to prevent repeating the same mistake again. A second change reduces the quality of evidence we obtain, which decreases the likelihood we will make an accurate choice.”
“In the end, these two processes cancel each other out, meaning that the deliberative approach we take to avoid repeating a mistake neither enhances nor diminishes the likelihood we’ll repeat it,”
Humans and monkeys showed strikingly similar behavior. After errors, both slowed down the decision-making process, but the pattern of slowing depended on the difficulty of the decision.
Slowing was maximum for more difficult decisions, suggesting longer accumulation of information. However, the overall accuracy of their choices did not change, indicating the quality of accumulated sensory information was lower.
