B) Helmholtz' theory
C) Brunzwik's probabilistic functionalism theory
D) none of the above

Question

Quizplus · Accepted Answer

No single theory can fully explain lightness perception, as it is a complex process that involves both bottom-up and top-down processing, as well as contextual factors. Wallach's ratio principle and Helmholtz' theory offer some insights into how brightness contrast and spatial frequency may contribute to lightness perception, respectively, but they do not provide a comprehensive account of the phenomenon. Brunswik's probabilistic functionalism theory is a general framework for understanding perception, but it does not focus specifically on lightness perception.
