What is difference threshold in psychology?

The just noticeable difference (JND), also known as the difference threshold, is the minimum level of stimulation that a person can detect 50 percent of the time.

The just noticeable difference would be the smallest change in volume that a person could sense..

What is a psychophysical function?

a psychometric relationship between a stimulus and judgments about the stimulus, as expressed in a mathematical formula. In the method of constant stimuli, it is the proportion of yes responses (i.e., that the stimuli were perceived) as a function of physical magnitude of the stimuli.

What is psychophysical nature?
