Figure 3

Proportion correct for letter identification is plotted as a function of letter position from fixation (negative values: left of fixation; positive values: right of fixation) for four observers. Individual observers' data are shown in the small panels while the averaged data are shown in the large panel. Data were collected for 0.8° letters the identities of which were disclosed to observers before each trial. Data were scored according to the exact (filled circles) and the either-position (unfilled circles) methods.
