The Ability of Color-Vision Defective and Color-Normal Early Elementary and Junior High Students to Utilize Color. Final Report.
Cook, Ann C. N.; Hannaford, Alonzo E.
The investigation was undertaken to obtain data on the number of kindergarten, second, and seventh grade Ss classified as having color vision defects by the American Optical-Hardy, Rand, Rittler Test (AO-HRR) and two tests by S. Ishihara. Also studied was the ability of color vision defective and color normal Ss to utilize color as measured by the Farnsworth Panel D-15 Test and the Dvorine Nomenclature Test. A single administration of the AO-HRR resulted in abnormally high percentages of Ss being identified as color vision defective. The AO-HRR classification of strong identified Ss at all grade levels who had problems utilizing color. Using the more stringent criterion of consistent failure on the AO-HRR and the two Ishihara tests, the percentages of Ss found to be color vision defective were lower than generally quoted in the literature, but approximately the same as cited for some school populations. A total of 2,476 Ss received initial testing, and 38 were found to be color vision defective using the three tests. A similar number of color vision normal Ss were selected as a comparison group. It was concluded that a factor or factors other than color vision are assessed by the AO-HRR Test when the published criteria are used with younger populations, that Ss who consistently manifest a color vision defect can vary in their ability to utilize color, and that Caucasian males manifested a significantly higher proportion of color vision defects than black males.
