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.
