Psychophysics is the primary scientific tool for determining how the physical world translates into the biological world of sensations. As a noninvasive methodology that uses behavioral measurements of sensory function, it is often the first port of call for developing the stimuli, procedures and methods of analysis for subsequent use in neurophysiological, electrophysiological and brain imaging studies of sensory behavior. Psychophysics is not merely a methodology but also a research area in its own right, advancing alongside other developments such as in mathematical analysis and computer technology. Although this article concentrates on psychophysics as applied to vision, the concepts and procedures described are applicable to all sensory modalities.
