The essays appearing in these two volumes are based on Keynote (Vol. 1) and State-of-the-Art (Vol. 2) Lectures delivered at the XXVth International Congress of Psychology, in Brussels, July 1992. The Brussels Congress was the latest in a series of conferences which are organized at regular intervals under the auspices of the International Union of Psychological Science (IUPsyS), the main international organization in the field of Scientific Psychology. The first of those meetings took place in Paris in 1889. An important function of the International Congresses is to promote communication between different specializations in Psychology. Speakers were therefore asked to present lectures and discussions in their own fields of study, in a way that would be accessible to fellow psychologists active in other fields. State-of-the-Art lecturers were specifically asked to prepare a tutorial review on a topic which, in the view of the Program Committee, had recently given rise to particularly important developments. These contributions are included in Volume Two. Keynote lecturers were left free to address whatever subject they felt was of greatest interest. The chapters in Volume 1 are preceded by the Presidential Address by Mark R. Rosenzweig.

AIMS AND ORGANISATION OF THE PRESENT REPORT This document is a report on the state of Cognitive Science research in the European Economic Community. Since Cognitive Science is a young discipline, we have taken part of our task to be an exposition of its goals, methods and progress, and of its significance for technology. Subsequent to this exposition we survey the intellectual resources devoted to Cognitive Science research within member nations of the EEC. Specific proposals for the advancement of the discipline in Europe are also formulated. In more detail, the six chapters comprising the report may be summarized as follows. -Chapter 1 (What is Cognitive Science?) is an overview of the major research themes that define contemporary Cognitive Science. The relation of these themes to current technological issues Is also briefly discussed. -Chapter 2 (Survey of cognitive competencies) treats four principal axes of Cognitive Science research In more detail. Our discussion Is at once theoretical and applied Inasmuch as we describe potential app lications of basic research to technological and societal issues. -Chapter 3 (Biological perspective on Cognitive Science) is a discussion of neuroscience approaches to Cognitive Science. This chapter is intended to under line the distinction between Cognitive Science and Artificial Intelligence. -Chapter 4 (Cognitive ergonomics) highlights the study of man-machine interaction. It may be usefully accompanied by FAST series N" 9: "Mismatch between machine representations and human concepts."
