色相配列検査法の検討—1．成績を係数で表わす試みおよびアノマロスコープの成績との比較

Evaluation of 100 Hue Test (Color Discrimination Test)

　100Hue Testの成績を詳細に検討するには，その総偏差点と記録図のパタンのみでは不十分であると考え，これを1つの係数で表わそうと試みた。

　検討に使用した検査器は日本色彩社の色彩弁別検査器である。対象とした色覚異常者は17〜29歳の男で，P16名，PA37名，D71名，DA111名，計235名である。

It is very difficult to evaluate exactly the results of 100 Hue Test by only comparing with that pattern or the total error scores. Hence we attempted to show the results of this test as a numerical index.

Because the pattern of errors are characteris-tically different in protan and deutan, it isnecessary to decide the different index respec-tively.

Arithmetic means of deuteranopes were plot-ted on the scoring sheet. We could divide the color circle into 4 quadrants. In first and third quadrant many errors were found, in seco and fourth quadrant a few errors. △ is the index for deutan.
