Signaalintunnistus
Signaalintunnistus, also known as signal detection theory, is a framework for studying how people make decisions in ambiguous situations. It is used to understand how observers detect signals from noise. The theory was originally developed by statistical theorists and engineers to help engineers distinguish between signals and noise in electronic systems. However, it has since been applied to a wide range of fields, including psychology, neuroscience, and medicine.
In signal detection theory, the observer is presented with a series of stimuli. Some of these stimuli
The theory proposes that the observer's performance can be described by two parameters: sensitivity and response
Signal detection theory has been used to study a variety of phenomena, including visual perception, auditory
