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 people undergo a specific developmental delay in the area of metarepresentational development. The delay facilitates mind-blindness. There is some evidence that suggests that certain patients develop a rudimentary ToM and do not suffer from complete lack of ToM causing mind-blindness. A study by Bowler concluded that mind-blindness and social impairment is not as straightforward as previously thought. It showed that a complete possession of ToM was not enough to protect from social impairments in autistic people. Conversely the absence or impairment of the ToM that leads to mind-blindness does not lead to social impairments. The social and cognitive differences seen
