Kids should pay more attention to mistakes, study suggests -- ScienceDaily

The children then took a fast-moving accuracy task on a computer while their brain activity was recorded. The task: Help a zookeeper capture escaped animals by pressing the spacebar when an animal appeared -- unless it was a group of three orangutan friends, who were helping capture the other animals, in which case they had to withhold their response. Within half-of-a-second after making a mistake, brain activity increases as the person becomes aware of and pays close attention to what went wrong. Essentially, a bigger brain response means the person is focusing more on the error. Children with growth mindsets were significantly more likely to have this larger brain response after making a mistake in the study. In addition, they were more likely to improve their performance on the task after making a mistake.
