Information on six research programs which studied eye movements during reading and evaluated aspects of PLATO-displayed reading instructional material is provided in this report. An analysis of eye movements of "competent" and "less competent" readers reading for general and detailed information showed many differences between them. One of the findings is that competent readers made fewer saccadic eye movements per line of print and spent less time on fixation pauses. In addition, when reading for detail, they did not change the size of the informational chunk taken in during each fixation pause but did increase the amount of time spent on such fixation pauses. Less competent readers decreased the informational chunk taken in per fixation but did not change the amount of time spent per fixation. Also reported are a pilot study concerning blink or saccad suppression of information, a study of eye movements as readers scan back from the end to the beginning of a new line, and the development of a procedure for measuring head movements. A study of informational chunking which investigated the effects of the wider angular distance of the PLATO display and typed materials suggests that a drop in efficiency of reading speed is noted when reading these compared to reading a printed book format.
