Signal detection theory miss
WebThe theory of signal detections provides the best approach to separate the effects of sensitivity from those of response bias. What led to a "yes" or "no" decision as opposed to "what did the subject hear (or not hear)?" A hit occurs when the signal is present and the subject says "yes". A correct rejection occurs when the signal is absent and ... WebSignal Detection Theory (SDT) offers a framework and method for doing this, and in general for distinguishing between the sensitivity or discriminability (d') of the observer and their …
