Thomas Stoffregen, Ph.D., School of Kinesiology professor and director of the Affordance Perception-Action Laboratory (APAL), was interviewed for a story about car sickness for The Pulse, a program on WHYY, a National Public Radio station in Philadelphia.

In response to the interviewer’s question on motion sickness, Stoffregen commented, “We move all the time and we don’t feel sick. The $64,000 question is, what causes it? Why would a conflict between what you expect and what you experience make you feel nauseous? Nobody really has the slightest idea why the symptoms are what they are.”
