Abstract
The aim of this research was to compare the photopic and scotopic spectral sensitivity of 2 New World monkeys which have not been previously studied ( Cebus Capucinus and Lagothrix) with that of a normal trichromatic and a protanopic human S and an Old World monkey ( Macaca mulatta). Spectral sensitivity was measured at different wavelengths using a modified method of limits. The results showed that the spectral sensitivity was identical for all Ss at a scotopic level. At the photopic level the normal human S and the Old World monkey also had a similar sensitivity. Both New World monkeys had a marked deficiency in the long wavelength part of the spectrum. This deficiency was comparable to that of the human protan. These results added therefore further evidence that New World monkeys are red deficient.Keywords
