Individual objective versus subjective fixation disparity as a function of forced vergence - Fig 5

<p>For Participants P12 and P03, the subjective (A) and objective (B) fixation disparity is plotted as a function of forced vergence, i.e., prism load. The same scales are used for both types of FD, in order illustrate the different amount of these two measures. The four colours represent the results of the four repeated measurements. Based on the combined data of all four repetitions, the equations describe the robust linear regressions lines with coefficients and 95%–confidence intervals (as subscripts); if the confidence interval (CI) is smaller than the amount of the coefficient, the coefficient is significant (two-tailed) based on all four datasets of one individual; significant coefficients are printed bold. A coloured dot is drawn at each coefficient if this coefficient is significant in one of the four repeated measurements. Thus, four coloured dots mean that this coefficient is significant in each of the four plots. The data of (A) and (B) are replotted in (C) for a regression of subjective fixation disparity as a function of objective fixation disparity, i.e., sFD_{i j} = k _i + C_i * oFD_{i j}, when the single measurements j are plotted directly relative to each other for each individual i.
