WebFigure 1: The model of sdt. stimulus with a value of x larger than 2 comes from the signal distribution and is given the response Yes. The position of the threshold can also be given relative to the signal distribution (because the noise has zero mean, B is the distance of the threshold relative to the noise distribution), as the mean of Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
