Abstract

Included among color vision testing instruments are the Nagel anomaloscope and the Pickford-Nicholson anomaloscope. The Nagel is a spectral instrument whereas the Pickford-Nicholson uses filters. This paper examines how closely the two instruments actually correspond. It is concluded that both instruments do quantitatively yield similar results on both normals and color deficients. The standard deviations of both the means and ranges on the two instruments are equal, at the .02 level of significance .
