Are they under the control of the visual information available in words and in scenes, or under the control of the meanings of those items, or is there little or no control at all? The origins of this volume are in discussions held at a meeting of the European Society for Cognitive Psychology (ESCOP) that was held in Wiirzburg in September 1996. Informally and formally, a number of us with interests in eye movements were arguing about the landing position effect in reading — an effect that, if substantiated, would provide evidence of the use of parafoveal information in eye guidance. The argument was not resolved in Wiirzburg, and so we decided to continue talking about eye guidance at a small meeting that was held in Chamonix in February 1997. Many of the contributors to this volume were present at that meeting, but the argument was not resolved in Chamonix either. We decided that the way forward was to extend the debate to encourage contributions from psychologists who had been unable to attend the meetings, but who were known to have views on the matter. And this volume is the product. The argument is still unresolved, but the problem is now clearer. ESCOP not only provided a forum for our initial arguments in Wiirzburg, but also generously supported the workshop in Chamonix. We are very grateful to the Society for giving us the opportunity to sit around a table talking about eye movements to fellow enthusiasts. Not all of the arguments in Chamonix centred upon questions of eye guidance of course, and academic rivalries saw expression in a number of competitions during our meetings. The most memorable must be the tall-story competition, which was won by an explanation of the events leading to one colleague arriving at the airport with minutes to spare before departure. This winning story involved a highly improbable overnight vigil and an illegal journey down a motorway. Chamonix also witnessed eye-movement researchers engaged in a glove-throwing competition (the best throw won by several hundred metres) and a self-mutilation-while-snow-boarding competition (the winning entry involved a party of French schoolchildren, blood spilt on the snow and, appropriately enough, an accident researcher). While our meetings have been fun, the most enjoyable aspect of the debate has been in helping this volume to completion. The contributors have responded to the original question with enthusiasm. They have developed a set of arguments, often supported with new data, that help us to understand how our eyes move in characteristic ways. Each of the chapters has been reviewed by at least two other contributors to the volume, and authors required to respond to reviewer's comments. The authors and reviewers have kept to a strict schedule. For their readiness in making the volume a coherent series of discussions around a single question, I am vplieased to acknowledge their contributions as authors and as reviewers.
