The Pseudoackromatic Stimuli Identification task (task 1) included 20 trials (10 for each stimulus set; 5 for the green semiset and 5 for the red one), for each colour transformation (Variantor, Coblis protanopia, Coblis deuteranopia).
Contrariwise, Figure 5 also shows that all the comparisons between Variantor and the expected values for deuteranopia (leftmost bars in Figures 5c and 5d) produced large and significant differences ([DELTA][h.sub.uv] between 12.33[degrees] and 17.39[degrees], p< 0.01; [DELTA][L.sub.r] between -0.42 and 0.23, p< 0.001).
Both for protanopia (rightmost bars in Figures 5a and 5b) and deuteranopia (rightmost bars in Figures 5c and 5d), [DELTA][h.sub.uv] values were large (between -45.79[degrees] and -34.72[degrees] for protanopia; between -41.35[degrees] and -33.08[degrees] for deuteranopia) and significant (p<0.001).
Red and green CVD (protanopia and deuteranopia, respectively) have the highest frequency in the general populations (Oriowo and Alotaibi, 2008).
In Pakistan, there is very little data available reporting the distribution of protanopia and deuteranopia in the general population.
Deuteranopia is one of nine classes of inherited defective color vision, and it affects 1% of men.
Only one class of defective color vision was studied because the inclusion of all four of the most common types of defective color vision -- protanopia, deuteranopia, protanomaly, and deuteranomaly -- would have increased the complexity of the experiment, especially considering that persons with the latter two vary quite a bit in the extent of their loss of color discrimination.
(26) Deuteranopia is found in about 1.3% of men and 0.01% of women.
The main cause of protanopia and deuteranopia lies in the unequal intergenic and intragenic recombination of the L- and M-cone pigment genes.
