psychophysics

 [si″ko-fiz´iks]
scientific study of the quantitative relations between characteristics or patterns of physical stimuli and the sensations induced by them.

psy·cho·phys·ics

(sī'kō-fiz'iks),
The science of the relation between the physical attributes of a stimulus and the measured, quantitative attributes of the mental perception of that stimulus (for example, the relationship between changes in decibel level and the corresponding changes in the human's perception of the sound).

psychophysics

/psy·cho·phys·ics/ (-fiz´iks) scientific study of quantitative relations between characteristics or patterns of physical stimuli and the sensations induced by them.

psychophysics

(sī′kō-fĭz′ĭks)

psychophysics

[-fiz′iks]
Etymology: Gk, psyche + physikos, natural
the branch of psychology concerned with the relationships between physical stimuli and sensory responses.

psy·cho·phys·ics

(sī'kō-fiz'iks)
The science of the relation between the physical attributes of a stimulus and the measured, quantitative attributes of the mental perception of that stimulus.

psychophysics

the study of the relationships between the subjectively perceived magnitude of sensations and their actual magnitude, particularly with regard to the ability to detect differences between stimuli of different magnitudes.

psychophysics 

Branch of science that deals with the relationship between the physical stimuli and the sensory response. The measurements of thresholds (e.g. visual acuity, dark adaptation) or matching of stimuli (as in the spectral luminous efficiency curve) are examples of psychophysics. See experimental optometry.
