<em><u>The original focus of swets' (1964) signal detection theory was improving the sensitivity of the air traffic controllers to plane blips.
</u></em>
Further Explanations:
Signal detection theory is the ability to recognize a stimulus when embedded in a disrupting background. It has a practical function such as to increase air traffic control accuracy. As per the theory, the viewer is required to differentiate amongst the trials in which a target stimulus is available. It also provides an objective measure of perceptual sensitivity also known as detection task. The credit for developing this theory is given to Ronald Sahyouni.
It is a bi-step procedure involving the actual strength of the stimulus that influences the observer's beliefof occurrence of stimulus and the individual observer's criteria for deceiving whether the stimulus happened or not. The theory has its vital significance in the taming of the sensitivity of the air traffic regulator as per the plane beep. It also aids to detect any foe plane in a specific region.
