Summary
Perceptual effects of spectral stimuli are explained by an empirical strategy where perceived color depends on the probability distribution of stimulus sources. This addresses the inherent ambiguity in color vision origins.
Area of Science:
- Vision Science
- Perceptual Psychology
- Color Perception
Background:
- Rationalizing perceptual effects of spectral stimuli is a long-standing challenge in vision science.
- The phenomenology of color perception has remained puzzling for over two centuries.
Purpose of the Study:
- To review evidence explaining the perceptual effects of spectral stimuli.
- To propose a unifying empirical strategy for color vision.
Main Methods:
- Review of existing evidence in vision science.
- Analysis of the role of probability distributions in perception.
Main Results:
- Perceived color is determined by the probability distribution of possible stimulus sources.
- This empirical strategy is consistent across various visual perceptual domains.
Conclusions:
- The inherent ambiguity of real-world spectral stimulus origins necessitates an empirical strategy in color vision.
- This strategy provides a rational framework for understanding color perception phenomenology.
