We Learn More From Success, Not Failure
There is a biological reason why we learn more from our triumphs than from our failures, according to new research at the Massachusetts Institute of Technology.
Scientists there have shown that the brain responds to success at the level of individual brain cells, but the neurons show virtually no response to failures.
The fact that we learn more from our successes than from our failures is not new. Even family pets respond more to reward than punishment, and so do children, according to numerous psychology studies.
But what wasn’t known until now is how feedback from the environment guides the learning, according to Earl K. Miller, professor of neuroscience at MIT and senior author of a study in the July 30 issue of the journal Neuron.
Miller and co-authors Mark Histed, now a postdoctoral fellow at Harvard Medical School, and Anitha Pasupathy, now an assistant professor at the University of Washington, reached their conclusions after studying neurological activity on the cellular level in monkeys, which, as we all know, have brains that function very much like ours.
“The main thing that’s new here is there have been a lot of studies about how the brain learns, but there is very little understanding about how feedback from the environment guides learning, and that’s critical because that’s the way we learn,” Miller said in a telephone interview. “We learn from the consequences of our actions.”
