研究了颜色诊断人工目标的颜色记忆效应。由于有关这些物体及其颜色的知识已经在日常生活中学习，这些刺激允许调查获得的物体知识对颜色外观的影响。这些调查与高级视觉中的物体和颜色信息如何相互作用的问题以及学习和经验对感知的影响的研究有关。为了识别合适的人造物体，我们开发了一种反应时间范式，测量（主观）颜色诊断。在主要实验中，参与者将16个这样的物体调整为它们的典型颜色以及灰色。如果无色物体以其典型的颜色出现，那么参与者应该将其调整为对手的颜色，以便主观地将其视为灰色。我们发现，关于典型颜色的知识影响了人造物体的颜色外观。这种效应在沿着日光轴上尤其强烈。
We investigated the memory colour effect for colour diagnostic artificial objects. Since knowledge about these objects and their colours has been learned in everyday life, these stimuli allow the investigation of the influence of acquired object knowledge on colour appearance. These investigations are relevant for questions about how object and colour information in high-level vision interact as well as for research about the influence of learning and experience on perception in general. In order to identify suitable artificial objects, we developed a reaction time paradigm that measures (subjective) colour diagnosticity. In the main experiment, participants adjusted sixteen such objects to their typical colour as well as to grey. If the achromatic object appears in its typical colour, then participants should adjust it to the opponent colour in order to subjectively perceive it as grey. We found that knowledge about the typical colour influences the colour appearance of artificial objects. This effect was particularly strong along the daylight axis.
