To test the hypothesizes, Structural Equation Modeling was exploited. The results of the study showed that: There is a meaningful relation between performance of management accounting's techniques and cognitive dissonance, framing bias and mental accounting bias. There isn’t any meaningful relation between performance of management accounting's techniques and ambiguity aversion bias
