As busy as teachers and scholars are, rarely do they find the time to sample widely from the table of scientific inquiry. This book offers the opportunity to do just that. The fourth volume in the "Studies in Perception and Action" series, it contains a collection of posters presented at the Ninth International Conference on Perception and Action, sponsored by the International Society for Ecological Psychology. Like its predecessor, this volume is a collection of short reports, mostly empirical in nature. The reports are considerably larger than the abstracts presented in the proceedings of many conferences, and provide the authors with opportunities to present arguments, methods, results, and conclusions in condensed forms.
