Abstract

If you stare at a waterfall, or look at passing scenery from the window of a moving train, you will have a strange sensation when you turn your gaze to something stationary. You can investigate these types of motion after-effects with simple equipment described by the Exploratorium. How long does it take to induce the effect? How long does the effect last? Can the after-effect be canceled by viewing motion in the opposite direction? (Staff, date unknown)

Some psychologists also apply these findings in order to design better products or to help people change their behaviors. Learn more about this career: Psychologist.
