A general method is described for using a Lisp Machine to study reading as it takes place. The method involves simulating, on the machine's CRT, a moving window that passes through the text being read. The speed and direction of the window can be controlled by the reader, or test probes can be coordinated within the text viewed. The method allows reading to occur in an easily monitored environment, and the reader can respond to the material being read in a flexible manner. Suggestions for

We describe a technique for studying the reading process. The method relies on a standard Lisp Machine both to present text to be read and to collect data on-line as the text is read. To restrict immediate vision ofthe text, a moving window is simulated on the computer's screen. The window then moves through the text. Two basic modes of operation are available for collecting data. One involves providing the reader with active control over window speed and, if desired, window direction. The other involves having the reader perform one or more subsidiary tasks as the text is read, and recording how and how fast the reader responds to these tasks. Historically, a number of window systems have been developed to study
