Psychophysical

Psychophysical: sharing the physical and psychological qualities. In the 19th century, German physicist, philosopher and mystic Gustav Theodor Fechner was revolutionary in terming psychophysics. In its simplest form, it is a mathematical relationship between one's internal (psychic) and external (physical) worlds on the basis on experimental data. Multiple studies are currently being conducted in relation to Fechner's ideas. ^[1]

Psychophysical may refer to:

• Psychophysics, the subdiscipline of psychology dealing with the relationship between physical stimuli and their subjective correlates, or percepts
• Erroneously to Psychophysiology, the branch of psychology that is concerned with the physiological bases of psychological processes including sensory processes, and is thereby connected to psychophysics
• Psychophysical parallelism, in philosophy, is the theory that the conscious and nervous processes vary concomitantly whether or not there be any causal connection between them.
