Use of behavioral assays to establish sensory capabilities of an individual
the branch of psychology concerned with quantitative relations between physical stimuli and their psychological effects
Deals with the relationship between human sensation and their physical stimuli. The psychophysical approach used in the study of manual materials handling (MMH) tasks requires the worker to adjust the weight, force or frequency in a handling situation until they feel it represents their maximum acceptable weight or force.
the study of the relationship between the physical characteristics of stimuli and the conscious psychological experiences they produce. (8, 152)
the study of the relationship between properties of the physical world (e.g. light intensities, colour variations, shapes etc.) and our sensations of them. Important, because often found that sensation is not linearly related to variations in stimuli. E.g. often found that the relationship between the intensity of a physical stimulus (such as light) and our experience of it is characterised by a power law.
A name used by Fechner for the science of the relationship between mental processes and the physical world. Now usually restricted to the study of the sensory consequences of controlled physical stimulation.
Psychophysics is a subdiscipline of psychology dealing with the relationship between physical stimuli and their subjective correlates, or percepts.
