What is true when there is a just-noticeable difference (jnd) between two stimuli?
A) They are detectably different.
B) They cannot be identified as different.
C) Fechner's law is supported.
D) An empiricist approach to psychophysics is appropriate.
Just-Noticeable Difference
The smallest change in stimulus intensity that can be detected, underlining the threshold at which a change is perceptible.
Detectably Different
The threshold at which a change in a variable or condition is perceptible or measurable from its previous state.
Fechner's Law
A principle describing the logarithmic relationship between stimulus magnitude and the resultant sensory experience's intensity.
- Elucidate the ideas of absolute threshold and difference threshold, alongside their significance in the realm of sensory perception.

Final Answer :
A
Explanation :
The just-noticeable difference (jnd) refers to the smallest detectable difference between two stimuli. Therefore, when there is a jnd between two stimuli, they are detectably different from each other.
