Abstract
The intensity of sensation depends in general on the intensity of the process in the end-organ and brain, which in turn depends in part on the intensity of the physical stimulus. There are, therefore, two relations to be considered: (1) the relation between the stimulus and the nervous process, and (2) the relation between the nervous process and the sensation. Taking Into account the relativity of sensations and the relativity of the estimation of sensations, we find difficulties enough to account for the fact that no laws of the quantitative relation of stimulus-intensity to sensation-intensity are discoverable at present. The nearest approach to a law of this kind is "Weber's Law," which deals with the intensity difference threshold only. After describing Weber's Law, the author examines the determination of the just perceptible differences in intensities and the relativity of sensation. The author concludes with a discussion of beats, an important phenomenon of intensity in the auditory realm. (PsycInfo Database Record (c) 2022 APA, all rights reserved)
