Memories of errors foster faster learning
Date:8/14/2014

ee the joystick, but it was represented on the screen as a blue dot. A target was represented by a red dot, and as volunteers moved the joystick toward it, the blue dot could be programmed to move slightly off-kilter from where they pointed it, creating an error. Participants then adjusted their movement to compensate for the off-kilter movement and, after a few more trials, smoothly guided the joystick to its target.

In the study, the movement of the blue dot was rotated to the left or the right by larger or smaller amounts until it was a full 30 degrees off from the joystick's movement. The research team found that volunteers responded more quickly to smaller errors that pushed them consistently in one direction and less to larger errors and those that went in the opposite direction of other feedback. "They learned to give the frequent errors more weight as learning cues, while discounting those that seemed like flukes," says David Herzfeld, a graduate student in Shadmehr's laboratory who led the study.

The results also have given Shadmehr a new perspective on his after-work tennis hobby. "I'm much better in my second five minutes of playing tennis than in my first five minutes, and I always assumed that was because my muscles had warmed up," he says. "But now I wonder if warming up is really a chance for our brains to re-experience error."

"This study represents a significant step toward understanding how we learn a motor skill," says Daofen Chen, Ph.D., a program director at the National Institute of Neurological Disorders and Stroke. "The results may improve movement rehabilitation strategies for the many who have suffered strokes and other neuromotor injuries."

The next step in the research, Shadmehr says, will be to find out which part of the brain is responsible for the "coaching" job of assigning weight to different types of error.
