Only those parameters are displayed that significantly affect any of the parameters based on the SRH test (see Table 8). Those combinations of variables were analyzed in detail that were significant even in the loglinear model (success \(\times\) image and success \(\times\) image \(\times\) subject). Regarding the success \(\times\) image \(\times\) subject parameter, each variable is significant, excluding FFD. \begin{table}

Table 8: The significant results of the Scheirer–Ray–Hare (SRH) test on the parameters of eye movements corresponding to the ring of the Landolt-C figure. Regarding the success \(\times\) image parameter, each variable is significant, excluding FFD and TTFMC. The following cross-tabulation tables of image x success parameter considers the results of each subject. Time to first fixation was longer in the case of failure than in the case of success. The longer fixation time increased the chance of failure (see Table 9). Fixation duration was always longer in the case of the colored image series than in the case of achromatic images. In the case of success, the duration of fixation decreased to the third part of that in the case of failure. The increase of the duration of fixation went hand in hand with the increase of the chance of failure (see Table 10). The visit duration was longer in the case of colored images, especially in the case of failure (see Table 11). The following cross-tabulation tables of subject \(\times\) image \(\times\) success parameter consider even the two groups of subjects. Based on the analysis of the experienced correspondences, it can be stated that, in the case of failure, anomalous trichromats fixated the achromatic figures significantly longer. Normal trichromats fixated the colored images shorter in time when they succeeded than in the case of failure. In the case of achromatic images, there was no significant difference between subjects when they succeeded (see Table 12). \begin{table}
\begin{tabular}{c c c} \hline \hline  & \multicolumn{2}{c}{**Image**} \\ \cline{2-3}  & **Achromatic** & **Colored** \\ \cline{2-3}  & **VD Mean (s)** & **VD Mean (s)** \\ \hline \multirow{2}{*}{Success} & Failed & 2.05 \({}^{\text{a}}\) & 3.35 \({}^{\text{b}}\) \\ \cline{2-3}  & Succeeded & 0.66 \({}^{\text{c}}\) & 0.99 \({}^{\text{d}}\) \\ \hline \end{tabular} The results of the Mann–Whitney statistical test are indicated by the letters in the superscript. If the letters (a,b,c,d) in the superscripts of two parameters are different, the two parameters are significantly (\(\alpha\) = 0.05) different from each other.
