What’s This Research About?

This broken escalator aftereffect has been proven in previous experiments.
In this study, they wanted to see if simply observing someone reacting to a
moving surface (sled) (not having previous experience with the sled) would
still result in compensatory movement to an anticipated unstable surface in
the observer. This effect would be explained by the presence of mirror neurons
in the brain. These mirror neurons allow people to decrease movement errors
by simply observing others in their social network. They also tested to see if
there was more of an aftereffect with an actor showing exaggerated amounts
of compensatory movement.
