Primates perceive their world through a multitude of ways. One way in which primates perceive their surroundings is via the colors that they can see (Surridge, Osorio, & Mundy, 2003). Color vision is an evolutionary trait that has provided survival benefits to primates through evolutionary time (Regan et al., 2005). However, among certain species of primates, there are drastic variations among members in terms of the colors that they can see, thus suggesting a polymorphic basis. A polymorphic basis is when a characteristic of a species varies among its members genetically (Gomes, Pessoa, Suganuma, Tomaz, & Pessoa, 2002).
New World monkeys, such as spider monkeys, are said to differ in comparison to other primates based the colors they can see due to a sex link theory (Goulart, Bonci, Galvao, Silveira, & Ventura, 2013). However, while New World monkey’s polymorphic basis for color vision is often documented in previous research, questions still arise as two why members of the human species vary among the colors that they can see (Gomes, Pessoa, Suganuma, Tomaz, & Pessoa, 2002).
According to Franklin, Sowden, Burley, Notman, and Alder (2008), among the human species, children with autism differ from their typically developing peers in their color vision abilities, thus suggesting that individuals with autism have an atypical form of color perception. In contrast, just as the New World monkeys have a polymorphic basis for the color vision characteristic based on sex, it…
