Color blindness all variations in human color vision involve the red and green receptors in male eyes. It is very rare for males or females to be "blind" to the blue end of the spectrum. The first scientific paper on the subject of color blindness, "Extraordinary facts relating to the vision of colours", was published by the English chemist John Dalton in 1798 after the realization of his own color blindness. Because of Dalton's work, the general condition has been called "daltonism", although in English this term is now used only for deuteranopia. Color codes present particular problems for those with color
Mind-blindness total loss of the ToM that would to mind-blindness. Some studies have shown that the orbitofrontal cortex is not directly associated with the theory of the mind or mind-blindness. However, a study by Stone and colleagues were able to show impaired ToM on mentalisation tasks. Since the frontal lobe is associated with executive function, researchers theorize that the frontal lobe plays an important role in ToM and its associated nature. It has also been suggested that the executive function and the theory of mind share the same regions. Despite the fact that ToM and mind-blindness can explain executive function deficits,
