The Oops! Response

Scientific American:

Is intelligence innate, or can you boost it with effort? The way you answer that question may determine how well you learn. Those who think smarts are malleable are more likely to bounce back from their mistakes and make fewer errors in the future, according to a study published last October in Psychological Science.

Researchers at Michigan State University asked 25 undergraduate students to participate in a simple, repetitive computer task: they had to press a button whenever the letters that appeared on the screen conformed to a particular pattern. When they made a mistake, which happened about 9 percent of the time, the subjects realized it almost immediately—at which point their brain produced two tiny electrical responses that the researchers recorded using electrodes. The first reaction indicates awareness that a mistake was made, whereas the second, called error positivity, is believed to represent the desire to fix that slipup. Later, the researchers asked the students whether they believed intelligence was fixed or could be learned.
