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)

Career Focus

If you like this project, you might enjoy exploring related careers.

Psychologist
Why people take certain actions can often feel like a mystery. Psychologists help solve these mysteries by investigating the physical, cognitive, emotional, or social aspects of human behavior and the human mind. Some psychologists also apply these findings in order to design better products or to help people change their behaviors.
  Neurologist
Each time your heart beats, or you breathe, think, dream, smell, see, move, laugh, read, remember, write, or feel something, you are using your nervous system. The nervous system includes your brain, spinal cord, and a huge network of nerves that make electrical connections all over your body. Neurologists are the medical doctors who diagnose and treat problems with the nervous system. They work to restore health to an essential system in the body.

Optometrist
Optometrists are the primary caretakers of our most important sense—vision. They diagnose and detect problems not only with vision, but with the health of the eye and the whole body. Based on their diagnoses, they prescribe glasses, contact lenses, and medications; refer patients to opthamologists for surgery; or develop treatment plans, like vision therapy, to help correct for deficits in depth perception. Their work helps people live better at every stage of life.
