Signal Detection Theory for the Development of the Model of Decision Making and of Subjects' Confidence in His/Her Decisions

Abstract

In the framework of signal detection theory using a multi-reference data of observations' description, the formulae for the calculation of correct responses probability in each trial were obtained. They explain the phenomenon of participant's confidence in his decisions. As a result of simplification of these formulae the heuristic model of decision making and confidence in it was elaborated. The model simulates subject's behavior more precisely then the previous ones.
