In philosophy, perceptual constancy refers to the puzzling phenomenon of the perception of properties of objects despite our changing experience of those properties.
When comparing magnitude production to ratio estimates (Da Silva), we again found similar exponents (n = .846 and n = .915--ours; n = 1.05 and n = .90--theirs), although 32-m range of distances were different from constancy value in Da Silva's investigation, while our [approximately equal to] 49- range produced perceptual constancy in all-cue conditions.
