The last 20 years have witnessed a revolution in reading research. Cognitive psychologists, using high-speed computers to aid in the collection and analysis of data, have developed tools that have begun to answer questions that were previously thought unanswerable. These tools allow for a "chronometric," or moment-to-moment, analysis of the reading process. Foremost among them is the use of the record of eye movements to help reveal the underlying perceptual and cognitive processes of reading. This volume provides a coherent framework for the research accomplished on the reading process over the past 15 years. It emphasizes how readers go about extracting information from the printed page and how they comprehend the text.
