In addition to conducting research in attention, memory, and skill acquisition, with applications in the field of ergonomics, Dr. Johnson is active in several professional societies and has served on a number of editorial boards. She is currently Secretary of the Dutch Ergonomics Society. Attention: Theory and Practice is the second book she has co-authored with Robert W. Proctor. The first, Skill Acquisition and Human Performance, was published by Sage in 1995. Together, Drs.
