The belief that the ability to detect a signal varies with the characteristics of the perceiver, the level of background stimulation, and the stimulus itself is called Signal-detection theory.
The ability to distinguish between information-bearing patterns that are random patterns that detract from the information (called stimulus in living creatures and signal in machines) is measured using detection theory or signal detection theory (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
The separation of these patterns from a concealing backdrop is known in the realm of electronics as signal recovery.
Theoretically, there are several factors that govern how a detecting system will detect a signal and what its threshold values will be. The theory can explain how altering the threshold will impact the capacity for discernment, often revealing how well-suited the system is to the task, purpose, or goal for which it is intended. When a human being is the detecting system, traits including past experience, future expectations, physiological state (such as exhaustion), and other elements can influence the threshold used. For example, a sentry in a conflict zone may have a lower threshold, making it more possible for them to notice fainter stimuli than a sentry in a peace zone, but they may also be more prone to mistaking harmless stimuli for a danger.
