  1. Values for reading accuracy in percent correct and reading speed in words per minute (WPM) are given for the three viewing conditions over the population of 23 subjects. Data are presented by font size and given as median values with differences to 16th and 84th percentiles. See Fig. 2 for a graphical presentation of these data.
