<P>Since 1991, the edited book series <I>Studies in Perception and Action</I> has appeared in conjunction with the biennial International Conference of Perception and Action (ICPA). ICPA provides a forum for researchers and academics who share a common interest in ecological psychology to come together, present new research, and foster ideas towards the advancement of the field. This volume highlights research presented at the 18th ICPA meeting, hosted by the University of Minneapolis in the summer of 2015. The short papers presented in this book represent the contributions of researchers and laboratories from across the globe, on a wide variety of topics in perception and action. This volume will especially appeal to those that are interested in James J. Gibson's ecological approach to psychology, as well as, more broadly, students and researchers of action and coordination, visual and haptic perception, perceptual development, human movement dynamics, human factors, and social processes.</P>
