Development of the Principle of Analyzing the Dynamics of the Psychophysical Indicator <i>d′</i> Using the “Moving Average” Method

The article describes the possibilities of using the “moving average” method in the analysis of psychophysical indicators using the example of indicator d′ used in the “Yes” method/No”, based on the Theory of signal detection. The general principles of applying the “sliding window” method to the psychophysical indicator d′ are considered, as well as the features of its use. Methods are described to test the basic assumptions inherent in the model of the Theory of signal detection, but in relation to dynamic data. Some possible tasks are analyzed, the solution of which becomes available when using this method of data analysis.
