Consequential Science: Psychophysical Technologies and Their Implementations

  • Eugene Galanter

An experimental science like psychophysics is often justified, and justifies itself, by the applica- tion of its methods to practical affairs. So Fechner’s early technological innovations, his “psy- chophysical methods,†that are now adumbrated in elementary textbooks of psychology, were adopted by ophthalmologists, audiologists, and others interested in prescribing emollients for human sensory limitations. They also helped the design and implementation of prosthetic devices based on the psychophysics of these perceptual functions. Advantage—psychosensory meth- ods—they improved the perceptual experience of these folks.
