What You See is Different from What I See: Species Differences in Visual Perception

  • Kazuo Fujita


Human perceptions of environmental events often differ from what they physically are. Suppose a man who has been talking to you at a distance of 1 m leaves you and walks away for a distance of 10 m. He should shrink to 1/10 of his real size because the retinal size of his image becomes 1/10 of what it was before. In fact, this idea never occurs to us; he looks almost as tall as he did at 1 m. This well-known phenomenon is called size constancy, and gives us an impressive example that what we see is different from what the real world is. In a sense, all perception is an illusion like this.
