Are effects of background contrast on color appearance and sensitivity controlled by the same mechanism of adaptation? We examined the effects of background color contrast on color appearance and on color-difference sensitivity under well-matched conditions. We linked the data using Fechner's hypothesis that the rate of apparent stimulus change is proportional to sensitivity and examined a family of parametric models of adaptation. Our results show that both appearance and discrimination are consistent with the same mechanism of adaptation.
背景对比度对颜色外观和敏感度的影响是由相同的适应机制控制的吗?我们在匹配良好的条件下,研究了背景颜色对比度对颜色外观和色差敏感度的影响。我们利用费希纳的假设(即表观刺激变化率与敏感度成正比)将数据联系起来,并研究了一系列适应的参数模型。我们的结果表明,外观和辨别都与相同的适应机制一致。
