The search for flavored particles is one of the most;interesting topics in high energy physics. Many experimental groups are working on this subject, but the solution to many of the problems are still open. Therefore it seemed very useful that people interested in these problems can probe then in a discussion. This is the aim of this Europhysics Study Conference, which has been organized both as a conference and a workshop. The present experimental knowledge on branching ratios, life­ times, cross sections and production mechanisms of flavored parti­ cles has been presented in general talks and discussed in the morn­ ing sessions, as well as the bases of the theoretical ideas and pre­ dictions. The experimental methods: visual detectors, live targets, high resolution vertex detectors, special triggers of search on fla­ vored particles, have been treated in the afternoon panels. These proceedings contain the talks and panel discussions with the exception of a few small contributions to the panels and talks by C. Baltay ("Search for charm and new flavors with bubble cham­ bers"), G. Alteralle ("Lifetime of charm and new flavors"), P. Monacelli ("Results on charm production from a CERN Beam Dump exper­ iment"), A. Capone ("Experimental study of same-sign dimunon events produced in neutrino and anti-neutrino beams").

From August 24-29, 1980 the international "Symposium on the Study of Motion Perception; Recent Developments and Applications", sponsored by NATO and organized by the editors of this book, was held in Veldhoven, the Netherlands. The meeting was attended by about eighty scholars, including psychologists, neurologists, physicists and other scientists, from fourteen different countries. During the symposium some fifty research papers were presented and a series of tutorial review papers were read and discussed. The research presentations have been published in a special issue of the international journal of psychonomics "Acta Psychologica" (Vol. 48, 1981). The present book is a compilation of the tutorial papers. The tutorials were arranged around early versions of the chapters now appearing in this book. The long discussions at the Veldhoven tutorial sessions resulted in extensive revisions of the texts prior to this publication. Unfortunately this led to a delay in publication, but we feel that this was justified by a greater depth of understanding which, in our opinion, has significantly increased the quality of the book. As they now stand, the chapters cover most of the issues relevant to the study of motion perception. Also they clearly reflect the intensive exchange of knowledge that took place during the symposium. As such we think that this book can be used both as an advanced text for students and scientists alike and as a comprehensive reference source.
