Field of Application+

Detailed Description+

Measures long-term focused attention and the visual differentiation of a relevant signal when distractor signals are present.
Signal detection theory describes the perception of weak signals against a constantly changing background. It addresses the following question: under what conditions can a person detect the presence of a weak signal against a background of irrelevant signals or among other signals that could sometimes be confused with the relevant signal? The test is used mainly in personnel psychology (safety assessments in aviation psychology), in clinical neuropsychology and in sports psychology. In the clinical context it is useful in identifying deficits, such as those that occur in connection with neglect.
