Question

Quizplus · Accepted Answer

Stevens's Power Law is a general principle that applies to all sensory modalities and describes the relationship between the physical intensity of a stimulus and the perceived magnitude of the sensation. Therefore, option C is correct. The law has been shown to hold true for vision, audition, taste, olfaction, and the skin senses. Option A is incorrect because the law applies to all senses, not just vision. Option B is incorrect because the law applies to all senses, not just vision and audition. Option D is incorrect because the law is both valid and reliable, as it has been tested and replicated in numerous studies.
