(Ph.D., University of California, Riverside) Dr. Atchley began his career in psychology conducting research at the US Army Aeroflightdynamics Directorate Crew Station Research and Development Facility at NASA-Ames, Moffet Field, California. His early work examined simulator sickness and how visual abilities interact with the perception of self-motion. Since then, he has conducted research on issues related to perceiving motion, especially as related to dynamic tasks such as control of locomotion and driving. Current research focuses on the interaction of attention and perception. He is particularly interested in how these two aspects of cognition are influenced by aging, performance of dual-tasks (such as conversing and driving), and smoking.
