Replotted data of subjective versus objective fixation disparity (see Fig 5).

<p>Lines connect data points of Session 1 and Session 2 for each subject to illustrate the similarity of these two results; triangles refer to Session1 and circles to Session 2. Two subgroups were formed based on whether the mean objective fixation disparity was negative (exo, n = 12) or positive (eso, n = 8).
