The ability to discriminate between two stimuli S1 and S2 depends on A) the absolute value of $\Delta$S = S₁ - S₂ only B) the value of S₁ and S₂ only C) the relative value of $\Delta$S to S₁ D) the value of log₂ S₁ E) the value of S₁

Question

The ability to discriminate between two stimuli depends on the relative difference between them, not just the absolute difference or the values of the stimuli alone. This is because perception often operates on a comparative basis, where the significance of a difference between stimuli is judged in relation to their magnitude.
