What does psychophysical mean?
Psychophysical describes the relationship between mental activity and physical or physiological responses. It is especially used in psychophysics, where researchers study how sensations, perceptions, attention, and other psychological processes correspond to measurable bodily events such as reactions, responses, or neural activity. The term is also used more broadly for physical changes associated with mental states, including the bodily effects of stress, emotion, or attention. It should not be confused with psychological, which focuses on the mental aspect alone. Psychophysical is a technical, somewhat formal term, but it is useful whenever an important connection between the mind and body must be made explicit.
Relating to the interaction or measurable connection between mental and physical processes.
"The experiment tested the psychophysical effect of visual contrast on detection speed."
Common in technical and scientific contexts, especially psychology, psychophysics, physiology, and neuroscience.
A psychophysical phenomenon or measure, especially one used to investigate the relationship between a psychological process and its physical expression.
"The laboratory recorded each psychophysical carefully, including response time and skin conductance."
Usually occurs in technical discourse or as a modifier, rather than being used as an everyday countable noun.
Psychophysical research turns inner experience into a measurable signal: thoughts, emotions, and perceptions can leave traces in the body.

Where does psychophysical come from?
Psychophysical was formed in the 19th century by combining the Greek-derived prefix psycho-, relating to the mind or soul, with physical, from Greek physikos, meaning natural or bodily. Its components reflect the emerging scientific study of relationships between psychological and physiological processes. The related field of psychophysics developed from this shared concern with connecting mental experience to physical measurement.

How psychophysical is actually used
This is primarily a technical term used in psychology, psychophysics, physiology, and related research. It is more precise than psychological when the connection to bodily measurement or response is central.
Easily confused with psychophysical
Psychological refers primarily to mental processes or experiences, whereas psychophysical specifically concerns the measurable relationship between those processes and bodily activity.
