Explain the relationship between criterion and sensitivity in signal detection theory.
What will be an ideal response?
In signal detection theory, criterion refers to an internal cutoff determined by an observer. The observer has one response for anything above this cutoff and another for anything below. Sensitivity refers to the ease or difficulty with which the observer can distinguish the signal from noise. The concepts are related. When sensitivity remains constant, criterion determines the ratio of hits to false alarms. For example, an observer with high sensitivity will generally have a high number of hits and correct rejections. However, if the same observer also has a low criterion, it can lead to many false alarms.
