Emmert’s Law specifies thatQuestion 5Answera.the nature of a sensation depends on which sensory fibres are stimulated, not on how fibres are stimulatedb.the smallest change in a stimulus that can be detected is a constant proportion of the stimulus levelc.the output of a photoreceptor depends on how many photons it absorbs, not upon the wavelength of those photonsd.perceived size is proportional to perceived distance for an object with a constant-sized retinal imagee.stimuli that are not fully visible due to occlusion by other stimuli must be more distant than their occluders
