Abstract The present investigation sought to examine and replicate previously observed patterns of both normal progressive and regressive saccades, as well as to further understand regression behavior by using a new experimental paradigm for experimentation and to compare previously unstudied characteristics of regressive eye-movements with those of normal progressive reading. A spatial memory component was also included in the main experiment to determine if those with better visuo-spatial working memory are able to make more regressions. The sample studied did exhibit normal progressive reading, and it was found that the saccade-distance effect for progressive saccades was absent for regressive saccades. Readers also seemed to exhibit two different regression strategies for locating previously fixated text. These two strategies seemed to rely on different cognitive processes, meaning that task type and information available for saccade programming may have an effect on the accuracy of a reader’s regressive saccades. Those readers with higher spatial memory made more accurate regressions with fewer total number of regressions to find the target.
