表面色知覚の心理物理学―実験の進歩と生態学的妥当性―

Humans easily perceive the color of objects. The ‘surface color’ perception has been defined as a problem of recovering the physical reflectance of a surface from the image, and its mechanism has been examined using artificial stimuli with nearly flat and perfectly uniform reflectance. However, recent studies using a variety of real-world surfaces suggest that the visual system estimates the surface color based on low- and high-level image features, similar to object recognition. The present paper reviews the experimental and theoretical development of surface-color perception research, and discusses how the ecological validity and diversity of stimuli is important for the reproducibility and validity of psychological findings.
