This book is the sixth volume in the "Studies in Perception and Action" series and contains a collection of posters presented at the Eleventh International Conference on Perception and Action. The series provides a written record of the research presented at the poster sessions to help spur dialog among researchers at the conference and to provide a reference source afterward. Each volume presents new research, almost always at the cutting edge of the discipline, and gives a special place to younger scientists whose work contains the seeds which will determine the future growth and direction of the discipline. Studies in Perception and Action VI offers the reader not just a cross-section of leading research at a given point in time, but a mini-history of ecological psychology and its development.
