近年来，人们越来越感兴趣的是澄清不同材料特征（如光泽度和透明度）的感知机制。在这项研究中，我们检查是否可以观察到知觉学习效果的材料知觉，以及是否积极进行材料判断任务的学习效果是重要的。观察员被分为两组;光泽度组和透明度组。前观察者重复光泽度判别任务，而后观察者重复透明度判别任务10天。我们测量了正确的反应率和反应时间的变化，学习前后的学习和未学习的材料特征的歧视。结果，在两个学习组中，学习后对所学材料特征的反应时间显着缩短。这些结果表明，人类视觉系统可以通过主动重复材料辨别任务来提高光泽度和透明度辨别性能。
There have been growing interests in clarifying perceptual mechanisms for different material features such as glossiness and transparency in recent years. In this study, we examined whether perceptual learning effects can be observed for material perceptions, and whether active conduct of material judgment tasks is important for the learning effects. The observers were divided into two groups; the glossiness group and the transparency group. The former observers repeated a glossiness discrimination task, while the latter observers repeated a transparency discrimination task for 10 days. We measured changes in correct response ratios and reaction times for discriminations of learned and unlearned material features between before and after the learning. In the results, in both learning groups, the reaction times for the learned material features were significantly shortened after the learning. These results suggest that the human visual system can increase glossiness and transparency discrimination performances by actively repeating material discrimination tasks.
