Abstract

The concept of a sensory threshold is a central element in sensory physiology and psychophysics. Yet it is a puzzle that a distinct threshold cannot be demonstrated. A fixed threshold would imply that stimuli above a certain strength are detected with certainty by a human observer while all stimuli below this strength escape detection. Experimental findings, on the other hand, demonstrate that the sensory threshold is a smoothly rising function, i.e. the probability of psychophysical detection gradually rises with stimulus intensity. The plot of the probability of detection as a function of stimulus strength usually follows an S-shaped curve.
