This study is a follow-up of a previous study of the effect of adaptation on heterochromatic matching by flicker photometry and direct comparison. In flicker photometry, two patches of color are applied alternately to a region of the retina adapted to a mixture of the two colors. In direct comparison, the two halves of the pattern are usually applied to regions of the retina adapted to the separate colors. Two additional methods of equalizing the state of adaptation in the two halves of the retina in direct comparison matching have been tested. In both cases, equalizing the states of adaptation reduces the discrepancy between flicker photometry and direct comparison for two of the three subjects tested. For the third subject, the discrepancies are small but one can still demonstrate effects produced by equalizing the states of adaptation. Further study is needed to delineate the specific mechanisms of adaptation involved.
本研究是对先前一项关于适应对闪烁光度法和直接比较法进行异色匹配影响的研究的后续研究。在闪烁光度法中，将两块颜色交替施加到适应了两种颜色混合的视网膜区域。在直接比较法中，图案的两半通常施加到适应了单独颜色的视网膜区域。已经测试了在直接比较匹配中使视网膜两半的适应状态相等的另外两种方法。在这两种情况下，使适应状态相等会减少所测试的三名受试者中两名受试者在闪烁光度法和直接比较法之间的差异。对于第三名受试者，差异很小，但仍然可以证明使适应状态相等所产生的效果。需要进一步研究来阐明所涉及的适应的具体机制。
