Signal detection theory originated in WWII radar plane detection
Evidence
This bias can be avoided if the subject is presented with an interval where the signal is or is not present. The interval is thus a period of time which can be indicated, for example, with a visual indicator on a computer screen. The length of the period is typically shorter than 10 seconds. The subject is asked whether the interval contains the signal, with the possibility of answering only âyesâ or ânoâ. This gives information about the tendency of the subject to favour either âsignal presentâ or âsignal not presentâ cases. The analysis of the results from such testing is formalized in signal detection theory, which is a theory of perceptual mechanisms when measuring thresholds (Gescheider, 1997). It was developed during World War II to correctly detect planes in noisy radar measurements. â Ville Pulkki, Matti Karjalainen, Communication Acoustics- AnâŠ, 887
