psychophysical approach  

Definition

  • Psychophysics is the study of sensory, perceptual, and cognitive systems, based on the evidence of human observers making judgments about what they see, hear, or feel. It is the oldest route to understanding the senses, with its roots in classical times and medieval Arab learning, flowering in the hands of 19th century geniuses such as Thomas Young, Hermann von Helmholtz, and Ernst Mach, and with increasing technical sophistication it is a key approach to understanding perception today.
