This volume is the outcome of the NATO Advanced Research Workshop on Time, Action and Cognition. which was held in Saint-Malo, France, in October 1991. The theme - time in action and cognition of time - was sparked by growing awareness in informal meetings between mostly French-speaking time psychologists of the need to bring together time specialists in the areas of development, motor behavior, attention, memory and representations. The workshop was designed to be a forum where different theoretical points of view and a variety of empirical approaches could be presented and discussed. Time psychologists tended to draw conclusions restricted to their specific fields of interest. From our own experience, we felt that addressing a common issue - possible relationships between time in action and representations of time - could lead to a more comprehensive approach. We are endebted to NATO for allowing us to bring this idea to fruition. We take this opportunity as well to express our thanks to Cognisciences ( Cognisud section) — an active interdisciplinary research organization - for its financial backing and the CNRS for its scientific support.
